Mount-builders always believed that there was no sense from the foil. However, this opinion is erroneous, and, with the right approach to its installation, you can achieve a special effect.

In fact, the foil is a thin layer of aluminum. When fastening it onto the walls under the wooden trim, everything is warm, which produces the boiler comes to the surface and reflected back. Thus, all thermal energy remains indoors. This layer is applied along with the insulation or separately. The corresponding material is able to reflect about 97% of heat, which is developed.

Dignity and disadvantages of material

Foil usually always comes complete with another type of insulation. It is rationally mounted in combination with glass gamble and other more dense materials. When these conditions are met, the material will have the following advantages:

Vapor insulation and thermal insulation - Thanks to this, hot steam does not pass in the middle of the insulating material, thereby keeping its properties, as well as heat inside the room.
Fire safety. Material withstands high temperatures and does not ignite. Prevents the spread of fire to other walls.
Possession of good sound insulation properties. Almost 70% suppresses noise from the street and inside the steam.
Bathing Bath Heating Time. Thanks to the correctly equipped insulation of the inner walls, the heat will fill the steepler and retain in it.

Despite the large number of advantages, this material is not devastable. These include:

continuous formation of condensate;
do not do without ventilation equipment;
the air penetrates badly, which is able to cause dampness and the appearance of mold;
the poisoning properties of aluminum (this metal is able to rolling into the body).

Proper room care, its regular ventilation is able to reduce all cons of minima. Therefore, after each bathing should not forget to open the doors, windows and outstands.

What manufacturer foil can be trusted

The building materials market present a sufficient number of brands specializing in the production of foil insulation. Among all, three manufacturers can be distinguished.

Isolon. Concern is located in Izhevsk. Specializes in the manufacture of foil and plastics. For the production of insulation, special technologies use. The material is produced in sewn and not sewn.
Penophol. This manufacturer makes a subtle material with a lack of substrate. At the same time, the structure is strong enough and reliable.
URSA.. One of the leading manufacturers in Spain. It makes high-quality insulation of different thicknesses and structures. This insulator is sold in Russia.

When choosing a brand, attention is paid to those brands that promise high quality and compliance with all the guests.

Foil Selection Rules for Bath

After examining all possible options and characteristics of foil materials, you can make the right choice. To do this, consider several simple criteria.

As for the thickness of the material, it all depends on how much the bath needs insulation. If the room needs to be isolated from the loss of thermal energy, then you can do the usual thin heat-resistant foil.

Brick Bath Foil

Brick walls do not differ good heat insulation, as they have cracks between the seams. For such premises, the foil canvas is used throughout the area. Mounted directly on the partitions. There is a small space, after which the root and skin is done. Therefore, it is better to buy material with a thick substrate.

In the steam room with concrete walls

Here the usual aluminum modification does not fit. In this case, it is better to use options with any substrate. This allows you to achieve efficient vapor barrier, reduce the risk of dampness in simpleness.

Save time: selected articles every week by mail

Let's start with the fact that many do not know at all, whether the foil is needed for the bath. The question is relevant for most of the owners of country houses. If you believe the professionals, then the foil must be used when finishing the bath, since it takes a sufficiently high temperature, which, besides, must also hold on. It is for this reason that the ceiling and walls are covered with an insulating material that prevents the output of thermal energy beyond the placement. Almost in all cases "Pie", which is formed on the inner surfaces of the bath in order to insulation, includes an aluminum foil. The latter, in turn, is made immediately in several options.

Be that as it may, we note that the foil recommended by one people for use in the bath is still categorically denied, and the dispute between the parties does not subside for a long time. That is why we have to deal with whether the foil really is so necessary or can you refuse it? In parallel, it will find out that this material is by itself, how can it be how much about it is and how to correctly perform installation for the maximum efficiency of the insulation layer.

And now, having familiarized yourself with the peculiarities and the main varieties of the material described in the article, you can proceed to consider some popular brands. For convenience of visitors, the information below is given in the form of a small pivot table.

As you can see, the cost of foil varies and depends not only on the variety, but also from a particular manufacturer.

Is the foil layer in the bath so need?

As a rule, the baths today are insulated with a thin foil (the thickness varies within 30-300 microns). Which is characteristic, the aluminum layer can be applied directly to the heat insulator or kraft paper and sold separately for subsequent use in tandem with other insulation materials.

Those who are against the use of foil assure that there is no sense from it, since it has a high thermal conductivity, and therefore it is simply unable to keep heat inside the room. The opponents of this method believe that the purchase / laying of the foil thermal insulator is just a useless waste of funds. Note that it is partly true, because the use of foil can be effectively only if it is properly installed.

That is why the room, when finishing the foil for a bath, heats up faster and keeps heat longer. Therefore, it will be quite logical that it will be comfortable to bathe in such a bath, while the cost of heating will be significantly reduced.

The main advantages of foil for the bath

In view of the operational and climatic features of the bathroom, you can select a number of requirements that are mandatoryly used by the aluminum foil must be configured:

high moisture and vaporistability;
appropriate thermal conductivity;
refractory;
high reflectivity (from 95 to 98 percent), which is obtained due to the special polishing of the outer layer;
canceled anti-corrosion properties.

As we have already found out, high vaporizolation characteristics prevent leakage of the heated steam out of the room, while it will not accumulate in the coating.

In addition, the aluminum foil for the bath has other advantages:

it is not deformed and does not lose its initial properties;
it protects the neighboring rooms in the presence of those;
the material is plastic, even if a long time is exposed to high temperatures;
features increased resistance to chemicals;
does not highlight harmful gases and compounds;
hygienic, durable;
resistant to UV radiation;
maximum easy to install.

Note! If the foil is neatly handled, then even the thinnest sheets will not be distorted. But in any case, it is necessary to acquire the material with a slight margin (at least 5 percent).

The maximum temperature that the foil can achieve 145 degrees. Thanks to the creation of the so-called thermos effect, heat inside is saved by about 2.5 hours longer. We also note that the material can be used both for walls and for floors and ceilings (that is, it is universal), and in no special processing of fungicides does not need any.

What to pay attention to when choosing a foil for a bath?

If you intend to purchase a suitable foil, then there are obliged to take into account several factors that affect the durability of the material, the convenience of its installation future efficiency. Consider the main selection criteria in more detail.

Key varieties of foil insulators for baths

Foil species, as well as combined insulation, in which it is present, there is a lot, all of them differ not only by cost, but also by various characteristics. We will consider today only the most common from the materials.

NO1 option. Roll foil (no basis)

This material is quite thin, and the strength of it can hardly be considered high. The thickness of such a heater can reach 0.2 millimeters, while the width varies in the range of 100-150 centimeters. The material is sold, as it was possible to guess from the name, rolls with a length of 5-20 meters. Used for mounting on the wall over already in the already occasional base insulator. Mustically attached with the allen, and the joints must be sampled with a metallized tape to obtain the most sealed reflective coating.

Note! The material can be used at a temperature of no more than +650 degrees, so the stewed steam room will quickly warm up and retain heat for a long time.

In addition, such a foil is resistant to corrosive processes, and during heating does not allocate any toxic substances.

Option NO2. Kraft foil

It is manufactured with the basis of the paper or, which is preferable, in a three-layer version (paper - foil - PE), also known as "Isolan". The strength is high enough, the material can be laid on top of a bar without using an additional heat insulator (provided that the walls are well legitimate). The material is environmentally friendly, its thickness can reach 1 centimeter. It can be operated at a temperature of no more than +100 degrees. Installation requirements are the same as in the previous case, however, it is more convenient to work with such material because it is more durable and not so much.

NO3 option. Fall.

In this case, it is about a vapor barrier, which can consist of one / two layers of foil material, as well as from reinforcing fiberglass mesh (the latter cells are 4x4 millimeters). Such reinforcement allows the material to maintain all its initial characteristics even at a temperature of -60 to +300 degrees! This material is environmentally friendly, is able to withstand considerable loads (including mechanical character). It is produced in several varieties. Sold with rolls with a width of 100 centimeters and 50 meters long.

NO4 option. "FOLGOZOLON"

Next, if you can express it, the foil for the bath is a foamed PE with a foil coating. Sold by sheets / rolls, may have different thickness. Very durable material that can be mounted without using the main insulation. It can be used not only for log walls (as the main heat insulator), but also for concrete / bricks (as auxiliary). The maximum allowable working temperature is about +125 degrees, dimensions (SHDCT) make up 60x120x2x11 centimeters. Cutting the material easily, as well as mount to the crate, but it is not deformed.

Option NO5. Minvata Foilized

The last variety of foil, which we will consider today. Sold with plates and rolls, the thickness varies in the range of 0.5-10 centimeters. Dimensions can be different, where much depends on a particular manufacturer. Excellent reflective ability - up to 97 percent, maximum permissible temperature - +300 degrees.

Note! There are a lot of types of foil minvati, but one of the most popular (at least in Russia) is the "sauna avo." having all the properties that require the specificity of this room.

Key features of insulation: What do you need to know?

Before entering directly to insulation, you should learn about the rules for its implementation, as well as about what is required to pay attention to. So that the foil participates in the support of the desired indoor microclimate, consider the following important points.

In the room must necessarily have a good ventilation. Otherwise, all thermal insulation layers will be poisoned and deprived of their initial characteristics. The foil material itself will be simply useless.
Between the finishing material and insulation layers should remain ventilation gaps.
Bold all the layers correctly, in accordance with the requirements, also do not forget to seal the joints between the sheets.

Remember that if you do not fulfill at least one of the listed requirements, then it is likely that all your efforts will be wasted, and the total thermo-and and sound insulation properties of the foil will be practically zero.

What should be the thickness of thermal insulation in the bath?

Here a lot depends on the thickness of the walls, as well as from the material from which they are made. So, for brick / concrete walls with a thickness of 25 to 35 centimeters, it is necessary to use a thermal insulator with a thickness of 10-15 centimeters. For the same walls, but with a thickness of more than 35 centimeters - within 8-10 centimeters. If we are talking about wooden walls with a thickness of 10-15 centimeters, then the thickness of the thermal insulator should be approximately 6-8 centimeters, if 15-20 is approximately 4-6 centimeters, finally, if more than 20 t - about 2-4 centimeters . As you can see, there is nothing complicated here, so we go directly to the installation work.

Step-by-step manual insulation bath

To begin with, we note that if the steamer is small, there will be quite enough foil in rolls or kraft foil, the thickness of which is at least 0.3 centimeters. But if the steamer is quite large, then preference is better to give materials based on mineral wool. More mandatory, consider how condensate will be assigned: if the ceiling is insulated, then the foil from it must be displayed onto the walls, and if the latter is insulated to the floor. The backstage should be approximately 15-20 centimeters, and all the joints will repeat, should be combined with a metallized scotch.

Note! You should not forget about the ventilation gap between the insulation layer and the finishing finish (about 1.3-1.8 centimeters). In this case, you will achieve a healthy microclimate indoors.

The installation process itself does not represent anything difficult and consists of several simple steps. Consider the features of each of them in more detail.

Step one. To begin with, build a crate on the walls using 5x5 centimeters for it. As for the shade of the crate, it in this case depends on what is the width of the insulation. If it is 60-120 centimeters, the step, respectively, should be 60 centimeters; For foil whose width is 100-150 centimeters, it is 50. To attach bars, use the apparent length of the appropriate length.

Step two. Put the insulated material between the bars. Try to do it in such a way that the heat-insulator does not go to the level of the planks.

Step Third. When the main insulation is installed, put a foil coating over it, compulsory with the last reflective layer inside the room. For sealing joints between sheets, you can use metallized tape, however, remember that the glue, being under the continuous exposure to the high temperature, softened, and therefore, the canvas may well dispense, which is shown to the tightness of the entire coating.

It is desirable that foil for bath Fixed with nails or brackets - the latter should be nailed directly to the bars. And if the width of the foil is quite large, it should be fixed both at the edges and in the center.

Step fourth. The trigger fixed by foil, not forgetting the air layer with a thickness of 1.5 centimeters. This layer is necessary in order to reduce the thermal conductivity of the foil in order to limit the reflection of all rays that hit the coating back into the room. Getting this kind of air "pocket" is possible due to the construction of a wooden crate under the lining. For this crate, try to use bars whose thickness is within 1-2 centimeters, and use all the same screws for fixation.

Sometimes the crate can be built over the insulation layer - foil in this case will be naked at once all over the area of \u200b\u200bsteam room, even on the bars. If so, then there is no particular need to create air "pockets", and the lining can be fixed directly on the crate. However, the practice shows that the use of combined materials, including a foil layer, is preferable not only in terms of economic, but due to a significant simplification of all installation work.

Thanks to the use of foil when finishing the steam, you can save from 25 to 30 percent on the stove fuel, in addition, the service life of the entire structure will noticeably increase, since you will prevent the development of mold, fungi and various kinds of microorganisms, harmful to health .

Features of Bani ventilation

As noted earlier, the arrangement of the high-quality ventilation system is mandatory for the normal functioning of the heat insulating cake. This should be taken in advance - even before it starts directly to insulation. There are several location of the holes for ventilation at once, you will get briefly with each of them.

First

We are talking about the scheme designated in the illustration above the letter "A". This is a natural ventilation, the intake sponge for it is placed at the bottom of the wall next to the heating device, and the exhaust is the opposite. The option is simple, but its effectiveness leaves much to be desired. For example, some doors open to enhance such ventilation.

Second

The option "b", in which both inventories are located on the same wall, and the heating device - at the opposite. Suitable for bath with one outer wall. To enhance the system, a fan is used (in the supply hole).

Third

As for the option "B", it needs to be implemented in the construction of a bath, since the air in this case will move under the pure floor. The location of the ventilation windows is the same, as in version number 1, but the fan should be positioned already in the exhaust hole (that from above). A fairly effective system, it is worth noting.

Fourth

Finally, the scheme "r" is effective only when furnaceing the stove. The hole here is only one - the supply - and it is located on the opposite wall opposite from the heating device.

As a result, we note that the size of the ventilation holes depends on the specific area of \u200b\u200bthe room. So, for each square meter, the steam should have at least 24 square centimeters. That's all, good luck in work!

Foil for a bath, which is better to choose, and is it necessary at all? This question arises from all owners of country plots, which decided to acquire their own poirs. Experts consider foil with one of the most important materials when finishing bathrooms, as they should quickly gain the necessary temperature and heat heat for a long time.

For this purpose, insulation on the surface of the walls and the ceiling is mounted, which will block the way out of the warmth of the bath. Almost always into the traditional insulation "pie", created on the inner surfaces of this structure, includes an aluminum foil produced in different versions.

However, it is necessary to state that this material, which is welcomed by one users, is completely denied by others, and between these "camps" there is an irreconcilable dispute. Therefore, it is worth to figure out how much this thermal insulation material is needed, or you can do without it. At the same time, let's see how the installation should be done so that the underlying layer be created properly.

Does the foil layer need?

For usually a thin layer of aluminum foil is used, the thickness of which is an average of 30 to 300 microns. It can be applied on kraft paper, directly on the insulation material or go separately from them and apply with other heat insulators in combination.

Opponents of the use of foil argue that there is no finishing from it, since aluminum has a high thermal conductivity and therefore it is not able to delay heat in the room - it will be unhindered outgoing. In their opinion, it turns out that the acquisition and installation of foil material is a useless waste of money and forces. It should be noted that this is to some extent - it is completely fair, since the foil will "work" only if its installation is carried out according to all the rules.

High thermal conductivity of aluminum foil will show itself negative if it is fixed directly on the cold wall, built from materials such as brick, concrete or foam concrete, without an additional insulation between them.

Secondly, besides the high thermal conductivity of the material, due to its structure, which is unable to keep the heated air indoors, there are other ways to recover heat - this is a convention and infrared radiation. Thus, the hot furnace gives the developed heat into the rooms mainly in the form of infrared rays that heat the surface when absorbing.

In case of heat rays on the aluminum foil layer, they are not absorbed by it, and they are reflected back to the room back. Thus, thermal energy is not waste on the heating of the walls, and is useful used inside. Therefore, it follows that the foil delays heat without due to its thickness or structure of the structure of the material, but by creating a reflective surface. Moreover, it should be noted that it is capable of reflecting up to 97% of the heat furnished.

Thirdly, the foil is an excellent vapor insulation for the insulation laid on the surface of the walls. It creates a hermetic, non-moisture coating, so prevents the outlet through the walls and the ceiling of the heated steam. This not only contributes to the preservation of heat in the room - vaporizolation does not give insulation to drink moisture and lose its thermal insulation qualities from it.

Therefore, sheathed with insulating material and supplemented with a foil layer quickly heats up and retains heat longer. Logical conclusion - in such a room, it is more comfortable to take bath procedures, with all that the cost of fuel or energy carrier will become much less.

Foil Selection Criteria for Bath

To determine the choice, first of all, it is necessary to take into account some factors affecting the efficiency of the material, the ease of installation of the canvas and the long-term operation. These criteria include the following points:

Foil, having a substrate, much easier to fasten to the crate, since the probability of its damage becomes significantly lower. Therefore, to acquire such a material - much more practical.

As a substrate for this heat-insulator, materials such as mineral wool foamed polyethylene or kraft paper can be used. In addition, the sale is presented with a foil reinforced with a fiberglass mesh, which has a thickness, slightly exceeding than that of the material without the base.

Foil for bath

For Bani's conditions, it is very important that the walls of the walls have resistance to elevated temperatures. This indicator must be at least + 100 degrees. The material for the bath must be resistant to the sharp drops of temperatures, and the rolled foil is even without the base, or having it, fully meets this criterion.
High-quality foil material should differ highly reflective ability of at least 95 ÷ 97%, since it will be directly dependent on the preservation of heat in the bathrooms.
If, the high thermal resistance indicators should also be assessed.
The vapor permeability of the foil layer should not exceed 0.01 g / m² in 24 hours.
The strength quality of the material is important in terms of the convenience of its installation.
A very important criterion is the ecological purity of foil material. When heated to high temperatures, it should not be released toxic substances.
Of course, you should evaluate the durability of foil material - what guarantees gives it a manufacturer, and how consumers speak about it.

Varieties of foil materials for thermal insulation bath

So, there are quite a few varieties of foil and foil materials that differ in their properties. The table contained below shows the most popular of them:

Illustration	Name and main characteristics of the material
	Rolled foil without base is a thin material, not particularly durable to the gap. It is produced with a thickness of 0.007 to 0.2 mm, in rolls of 5, 10 or 20 meters, wide from 1000 to 1500 mm. The unduminarious foil is used for mounting on the walls of the bathrooms, on top of the previously laid insulation. The material of the material is fixed by the blast, and their joints are necessarily sampled with a metallized tape, forming a hermetic reflective surface. The operating temperature limit for foil reaches +650 ° C. The ability to reflect the heat radiation is up to 97%, so the foil is able to ensure fast heating with a steam room and a long time to maintain a comfortable temperature in it. The material is resistant to corrosion and does not release toxic substances when heated.
	Kraft foil is performed on a paper basis, as well as in a three-layer version, consisting of foil, kraft paper and polyethylene - this material is called "Isolar". Kraft foil has good strength characteristics and can be used to secure on well-walled walls from the bar without additional use of the insulation. Kraft foil is an environmentally friendly material, since it does not release toxic evaporation when heated. The thickness of this insulator varies from 0.03 to 1.0 mm. Operating temperature - up to 100 degrees. With proper installation and sizing the joints with metallized chest, the material creates a hermetic, well reflective heat layer - reflective ability reaches 95%. The material is more convenient in the installation compared to the unduminarious foil, as it is less than the moment and is durable.
	Fallear is a vapor barrier, consisting of one or two layers of aluminum foil, between which the fiberglass mesh with cells 4 × 4 mm, which is the reinforcing web element. Due to this hardification, the foil insulator retains its qualities even in the temperature range from -60 to 300 degrees. Falloar is an environmentally friendly material that does not contain carcinogens and allergens, withstands high loads, including mechanical. Such material produced three types: - "A" - sheets with one-sided foil and operating temperature from -40 to +150 degrees; - "B" - canvas with bilateral foil and operating temperature from -40 to +300 degrees; - "C" - sheets having a one-sided coating of a foil and an adhesive basis for fixing on smooth surfaces of the walls, ceiling and floors. Operating temperature from -40 to +80 degrees. Standard roll parameters - length 50 m, width 1000 mm.
	"FoloSolon" is a foamed polyethylene having a foil coating. It is produced and comes on sale in the form of rolls or sheets, depending on its thickness. This insulation has high strength, depreciation and sound insulation characteristics. Since such canvases (sheets) may have a sufficiently large thickness, they are often fixed on the surface without additional thermal insulation materials, provided that certain conditions are met during the arrangement of the room. "FoloSolon" is used to insulate the log surfaces, as the main heat insulator, or concrete and brick walls, as an additional layer to the main insulation, installed between the bars under the cladding cladding. Material sheets have the following parameters: - thickness - 20 ÷ 110 mm; - Length 1200 mm, - Width - 600 mm. Rolls: - thickness - 2 ÷ 10 mm; - Length - 25 ÷ 30 m, - width - 1000 ÷ 1200 mm. The operating temperature range is + 100 ÷ 125 degrees. The material is not deformed, it is easy to cut and fastened on a wooden crate with the help of brackets and a stapler, and on a metal profile - using bilateral scotch.
	Foil mineral wool is made in rolls and plates with a thickness of 5 to 100 mm. The material may have different lengths and width - these parameters may vary from different manufacturers. The reflective ability of the material comes to 97%, the operating temperature is from -60 to 300 degrees. The varieties of foil minvati are many, and one of the most popular in the Russian market from this line of materials is a basalt thermal insulator for the bath "IsOVER Sauna", which has all the qualities necessary for such specific conditions.

How to conduct insulation correctly?

Before moving to insulation measures, you need to find out how to carry them out correctly, and that it should be foreseen.

In order for the aluminum layer to participate in maintaining the necessary microclimate, as well as conceived by the manufacturer, it is necessary to take into account the following points:

Mandatory arrangement Ventilation Bathrooms. Otherwise, all insulation layers will be impregnated with moisture and lose their thermal insulation qualities, and the foil will be simply useless.
Compliance with the parameters of the insulation thickness in relation to the thickness and material from which the walls are derived.
Proper fixation of layers of insulating and foil material and sealing of joints between sheets.
The formation of ventilation gaps between layers of insulation and finishing.

We must not forget that non-fulfillment of even one of the listed conditions is fraught with the fact that all the efforts attached during the installation of materials will be wasted, as well as vapor insulation and heat-reflecting qualities of foil insulation - are reduced to zero.

Ventilation of bathrooms

Properly organized ventilation system Parling is one of the main conditions that are necessary for the proper functioning of thermal insulation. Ventilation plan in advance before starting insulating operations. There are four main schemes for the location of the ventilation holes in rooms with high humidity and, accordingly, the distribution of air flows with a prerequisite for maintaining the optimal temperature regime.

The first embodiment, presented in the diagram under the letter "A", is a natural ventilation system. For her, holes are satisfied on the opposite walls of the room:

- at the bottom of the wall, next to the stove-heater, the supply hole is made;

- On the opposite wall, in its upper part - exhaust window. The exhaust window is advisable to place the partition so that the pair does not create direct drafts.

Both windows must necessarily have adjusting inflows and an outflow of the door of the door.

This option can be called the easiest in the arrangement, but not enough effective. The air flow falling into the supply hole is heated immediately by passing by the furnace, and then it immediately rises to the ceiling and goes to the hood. As a result, there is no proper ventilation of the room, since the air masses move along one trajectory, without covering the distant corners of the steam room. That is why the exhaust window is better to place the partition.

Strengthening such ventilation after the adoption of procedures will have to be due to the open door.

The second scheme (b) represents the ventilation system in which both holes are input and exhaust are on one wall, and the furnace is set near the opposite. Such ventilation is usually arranged if the bath has one outer wall in which the ventilation windows are mounted. In this embodiment, the ventilation system is enhanced by a fan, which is installed in the lower supply hole, so called forced. The fan makes the air intake in the room more intense, so its flows are separated and covered most of the steam room.

A more efficient way of ventilation parches: the supply hole is downstairs behind the stove, exhaust - on the wall on the contrary, but not at the top, and below. In this case, the exhaust hole needs to be equipped with a fan. With this arrangement of the beats in the steam room, the cold air heats up from the stove, climbs up, it cools and lowers down.

The third option (B) is implemented during the construction of the bath, as it assumes the passage of air under the "clean" floor. In this case, ventilation windows are located in the same way as in the first version, that is, on opposite walls, but the fan is installed in the upper exhaust ventilation window. In addition, air flows are divided due to the holes in the floor and the gap between the opposite wall and the "clean" surface of the floor, since additional traction is created thanks to such a design. Such a system can be called effective, since evaporations do not have time in large quantities to settle on the walls and the ceiling.
The fourth system (d) will only work during the furnace furnace. Having arrange it, they make only one inlet hole, which is located on the wall opposite the furnace. In this embodiment, hot airs from the furnace rises up, then cooling down, lowers down, mixed with the incoming cold air, and is displayed through the confusion door.

There is another system in which the exhaust air is output through confused. It is in such a way that the configuration is below the level of "clean" floor, and at the top of the foundation there is a supply hole, which will be in the space between the "black" and "clean" floor. So, the air falling through the hole in the foundation will provide ventilation not only underground space, but also the lumen between the foil and facing material of the bathroom.

Ventilation windows must be of size, which will be proportional to the area of \u200b\u200bthe room of the steam room. So, on 1m² of ventilated area, the window must have at least 24 cm².

Folgized insulation

Proper ventilation bath is the key to its long-term operation!

More information about all nuances of arrangement can be obtained from a special publication of our portal.

Wall thickness and insulation used

From how correctly the thickness of the insulation for the walls of the bath will be selected, the effect of the foil material will be dependent. In order to decide on this parameter, you can use this table:

Wall material	Wall thickness steam steam	Heater thickness (recommended), mm
Concrete, brick	350 ÷ 370 and more	80 ÷ 100.
Concrete, brick	250 ÷ 350.	100 ÷ 150.
Wooden log	100 ÷ 150.	60 ÷ 80.
Wooden log	150 ÷ \u200b\u200b200.	40 ÷ 60.
Wooden log	More than 200.	20 ÷ 40.

It should be understood that the indicated insulation thickness is precisely for the bath, that is, for short-term reception of bath procedures, and with the obligatory use of a foil reflective layer directed into the premises. For the premises of permanent residence of people, the criteria for selecting the thickness of the insulation will be others. And there can no longer do without calculations.

How to determine the thickness of the insulation of the external walls of the residential building?

There is a very affordable and convenient algorithm for calculating the heat engineering characteristics of the wall. With all the details, it is set forth in the article of our portal dedicated to. There is also a convenient calculator for independent calculations.

Wall insulation Baths using foil materials

Properly mounted on the walls and ceiling of Bath "Insulation Pies" directly affect how comfortable will the atmosphere in the premises. In addition, a violation of thermal insulation technology can be in disrepair not only the insulation itself, but also the walls of the structure.

The order of installation of the insulating system may vary somewhat - depending on the material from which the walls are built.

Warming Bath - Wooden Sir

Wood has a low thermal conductivity and high ability to maintain heat inside a log house, subject to high-quality cacked of a log docking or a bar. Therefore, for the insulation of the bath from this material there is its own technology.

1 - log wall.

2 - foil polyethylene.

3 - case of a bar.

4 - - Wooden lining or tank board.

Work on the consolidation of materials is carried out in the following order:

Illustration
	The walls are used on the insulated carriage, the walls are stretched and fixed with a stapler and brackets foamed foil polyethylene or even a non-free foil. The material of the material is fastened with a reflective coating inside the indoor of the venge of 150 ÷ \u200b\u200b200 mm. If a heater is selected, which has a sufficiently large thickness - at 10 ÷ 15 mm, then in this case, the sheets are fixed, without gaps.
	Fixing foil material, it is necessary to constantly monitor its integrity, since even a small damage can disrupt the intended effect of insulation and vaporizolation. If the material was accidentally damaged, it immediately needs to be sealed with a special foil scotch. The next step is all the canvas along the alternation line or joints are glued to the same scotch, so as to create a hermetic coating over the entire wall area.
	From above, on a foil insulation, rails with a cross section of 30 × 50 mm are fixed. They can be installed vertically or horizontally, depending on how the boards of lining is planned: in any case, perpendicular to the inner trim.
	The finish is mounted on the workshop. Between her and the foil surface should be required to remain a ventilation gap, which, in fact, and set the craters racks - 30 mm.

All operations for internal insulation of bathrooms are made only after the shrinkage and the execution of the secondary cacopate, otherwise the decoration of the decoration and the rupture of the insulation can occur.

Warming of brick or concrete walls bath

The insulation of the cold walls derived from brick, concrete, as well as foam concrete blocks, is somewhat different from similar operations with wooden structures, and is made as follows:

Illustration	Brief description of the operation
	The first step of the walls are placed, and the bars of the crates are fixed, thick in cross section equal to the thickness of the insulation, as it should get up between the bar flush. Moreover, if it is planned to install the lining vertically, the bar is attached either vertically, since to secure the trim after fixing the foil will be installed another number of bars a counter test, perpendicular to the already installed. The bars of the frame of the frame is mounted at a distance of each other, which will equal to the maximum tightly to put the insulating plate plates between them.
	If ventilation windows or holes are installed on the walls, it is necessary to fix the bars around them in the section as the remaining elements of the crate, since around them will also need to fasten foil.
	Further, there is a thermal material between the cluster of the mosser. For the bath, the modified hydrophobic basalt wool is most often used, for example, a vapor-permeable and waterproof insulation "Rockwool".
	The next step, the insulation is closed by one of the varieties of foil material - it can be a conventional foil without a substrate or foamed foil polyethylene. Foil fastening to cruciform bars is carried out using brackets and stapler. If the foil canvas are consolidated horizontally, its installation begins on the floor. If the foil has a small thickness, then its second stride is superimposed on the bottom brace of 150 ÷ \u200b\u200b200 mm. With a thickness of a foil material at 10 ÷ 15 mm, the canvas are mounted asking, as well as when mounting on a wooden wall.
	Around the ventilation holes and windows, Foil also need to fasten well, killing to pre-mounted bars. If there is an opportunity, it is desirable to hermetically glue the edge of the foil around the holes or windows with scotch.
	Foil sheets are bonded between themselves at the joints of the metallized scotch. If the surfaces of the walls and the ceiling are insulated, then a part of the sheet is recommended, about 200 ÷ 300 mm mounted on the ceiling, omit onto the wall so that the joint between the two planes is tightly closed.
	Top of foils are fixed with a thickness of 20 ÷ 25 mm thick, width of 40 ÷ 50 mm, which will fix the foil and insulation, create a gap between the foil and the trim, and will also serve as a crate for further installation of the lining.
	The next step is the lamp is trunks, but you need to trace the distance between the clap and the foil, the distance, at least 20 ÷ 25 mm be preserved. This space is necessary to ensure efficient ventilation and evaporation of condensate formed after each bath procedure.

In conclusion, I would like to reiterate that the foil will become an excellent obstacle from the penetration of moisture into wall structures and in the overlap, it will help to maintain a comfortable temperature in the steam room, but, if complying with all technological rules of its use during the warming of the walls and the ceiling of the bath. Therefore, it is not necessary to doubt its need.

Nowadays, the covering of steam aluminum foil is very popular. What are the advantages of this material, why best choose foil? Let's try to figure it out.

First, the steam room is a room that is used to treat very many diseases, including diseases of the respiratory system. Therefore, only such materials that are not separated by a pair of toxins and other harmful substances can be used to cover the steam room. It is like that of the material and is foil.

Secondly, with this method of the condensate condensation on the walls of the steam, that is, it does not happen on a wooden trim, and the tree does not deteriorate.

Thirdly, the foil retains its structure and shape even with the largest heating, while other materials can be deformed when heated.

Fourth, such a room heats up much faster than any other, in the steam room, which was trimmed with foil, warm steam is held as long as possible, so bath procedures can be continued as much as they need with minimal fuel consumption. The foil has a reflective effect, precisely because of it heat is saved so long.

And finally, fifthly, the foil does not miss moisture. Therefore, the insulation that is under it does not suffer from a hot couple, which means that your wage will serve you for a very long time.

What is the foil?

If you decide to sew a foil steam, you need to learn about the types of foil and the features of such a coating.

Most often weave aluminum foil.

Its species is determined by the presence of additives.

Foil is simple, fabric and foil paper. The best foil for the steam room is simple, which can withstand very large temperatures. The sheet of such a foil has a thickness of 0.03 to 0.3 mm. This is enough so that such a sheathing has taken out all the necessary loads. Of course, it is better to acquire a thicker foil. The foil must be at least 99 and a half percent of aluminum. Ten square meters of such material are less than 500 rubles, which is very profitable. Each roll of foil has labeling "T" or "M". The letter "T" means "hard", and the letter "m" "soft".

Fabric foil costs somewhat more expensive. Such a form of foil has several varieties - based on fiberglass or pholoisol. The tight variety of tissue foil is called canvas foil. For the steam room, it is not used as often as a simple foil, because she misses couples, although it is very well kept warm.

Paper-foil is made on the basis of cellulose, which is covered with a thin layer of aluminum. Such material does not withstand the temperature above +120 degrees Celsius, so it is better not to use it for the wage. But this foil can be seen by the pre-tribades and other adjacent premises. Such a foil is perfectly suitable for the cattle between the pipes, as it is very plastic. It is worth such material very cheap - 10 meters can be purchased for the amount of less than 300 rubles.

How to shelter a stewed steam?

The plaider of the Foil Steer should begin after the room of the bath gave a natural shrinkage, the walls were cocoon and insulated.

1. The room is measured and determined how many rolls of foil must be purchased. Usually simple foil is sold by rolls of 10 meters. It should be remembered that each sheet needs to be attached not to join, but a mustache, not less than twenty centimeters, so the material should be bought with a margin.

2. Foil sheets are nailed to the walls of galvanized nails. The reflecting surface of the foil is sent inside the room.

3. If during the installation, some sheets received small damage, they are stuck with the help of metallized tape. If damage is too significant, this sheet is better replaced. Scotch is glued and along the butts of sheets.

4. A doomle made of specks with a cross section of about five square centimeters. The finishing material is installed on top, for example, lining. The finishing material should not be installed directly on the foil, must be a short period.

Myth about foil and its disclosure

There is a steady myth that the foil in the bath is harmful and misses the heat outward, preventing effectively warm the bath. This myth is easy to debunk.

First, in front of the foil is the coating material that takes on most of the thermal energy. Secondly, behind the foil is the insulation. So added foil can not increase thermal losses, and can only reduce them.

Also, some people say that excessive humidity and lack of air passage foil will lead to a damage of wood. It is not true. First, to condensate steam on the foil (not on the trim), there is a place, and secondly, in the bath there should always be forced exhaust ventilation included by the user.

Timely and high-quality insulation of the saunas and baths can provide reliable protection of the finished designs of premises from high humidity, fungus and further destruction.

The folgized insulation for the bath contributes to effective energy saving, which leads to accumulation of 98% of the heat in the room. This allows you to save on the fuel and at times to speed up the process of the pair of steam.

What is the foil for?

The foil for the bath is the finest aluminum layer, which is used in its original form or in an effective combination with fiberglass, rolled insulation or kraft paper. The thickness of the canvas ranges from 30 to 300 microns.

Aluminum foil is distinguished by high thermal conductivity, therefore is a powerful heat reflector that is released by the fuel. The insulation of this type does not absorb infrared radiation, and reflects it, effectively distributing around the perimeter of the room.

Due to this, all the highlighted heat accumulates inside the pair. Among other things, such material is successfully used as a sound insulation.

According to experts, this is the best thermal reflector designed for modern baths capable of reflecting up to 98% of the radiation of the infrared spectrum allocated by the fuel.

Aluminum foil is an effective sealant that does not transmit steam and water, which means that it prevents moisture outlets outside the premises. The stew covered with foil is heated faster and cools slower.

Characteristics and advantages

Given the operational features of various bathrooms, thermal insulation from foil must comply with the following requirements:

High vapor and moisture resistance;
Excellent refractory properties;
Resistance to corrosion processes;
High level of thermal reflectivity (up to 98%) due to the mirror top layer;
Sufficient thermal conductivity;
Resistance to high temperatures;
The absence of toxic substances.

High vaporizolation characteristics prevent the outlet of the steam from the heated room and reduce the likelihood of condensate formation. This provides a long service life and an excellent appearance of the insulation.

The foil for the bath has the following advantages:
Resistance to deformations and plasticity in the heating process;
Preservation of initial consumer characteristics;
Inertia to the effects of ultraviolet radiation;
Protection of premises from condensate, fungal formations and malicious organisms;
Resistance to the effects of chemicals;
Simplicity and availability in carrying out installation work;
Durability, practicality and wear resistance;
Hygienic and environmental friendliness;
Available cost.

Aluminum foil is able to withstand high temperatures up to 150 degrees, which in combination with increased reflectivity contributes to the effective preservation of the heat released indoors.

Such unique characteristics allow you to create a thermos effect in the bath, so the material is ideal for the insulation of wall, ceiling and floor surfaces in the steampers and technical premises.

Varieties of foil

Depending on the type of application and auxiliary components that are part of the composition, the material is divided into several types:

The material is represented by a thin aluminum layer with a thickness of up to 300 μm, roll width up to 150 cm. Designed for a wide temperature range, so used for paired baths and saunas. Given the high probability of deformations and breaks when laying, it is recommended to apply foil to the refractory heat insulating base with fixation on metal brackets.

It is a cellulose base with an aluminum top layer. Paper withstands high temperature modes from 50 to 125 degrees, so suitable for auxiliary and technical room baths.

Material consisting of a fiberglass base and an aluminum layer. It has high sound, heat, vapor and moisture insulating characteristics, resistant to rotting and the appearance of mold.

The special type of insulation, the basis of which is the foamed polystyrene foam, covered with a thin aluminum layer. It is represented in rolls and sheets. The advantages of such a material are resistance to high temperatures, excellent refractory, heat-insulating characteristics and simplicity of installation.

The material base is a mineral wool covered with a thin layer of aluminum. It has high heat and vapor insulation properties.

Plates are easily installed on ceiling and wall surfaces, so baths are intended for use in any room.

Criterias of choice

The most effective option for the insulation of the room of the bath is an aluminum foil.

When choosing a foil insulation for a bath, it is important to comply with simple recommendations:

The main criterion for choosing foil in rolls is the thickness of the aluminum layer, which determines the coefficient of vaporizolation. This indicator ranges from 0.007 to 0.2 mm. The more thickness, the more reliable protection.
High-quality thermal insulator should consist of 99% of aluminum.
When choosing a reflector from aluminum foil, pay attention to its marking. So, the letter designation "M" is marked with a soft impeded material; "T" - a solid nearby basis.
A qualitative insulation must have all the necessary quality and imprisonment certificates. Therefore, it is recommended to choose products of reliable and proven suppliers.
The installation of the foil case is carried out using a tape on a metal basis (to hide joints), as well as galvanized nails, screws and brackets.

How to perform the trim bath foil yourself

The heat insulation of the wooden bath is performed by the method of cauldium. But mineral wool can be used as an additional insulation.

The use of foil cover is an important procedure that helps reduce heat loss in the premises. In this case, the material is used as a heat transfer device, which is mounted on the walls of logs or boards. Next is installed wooden lining.

Sequence of mounting work for insulation Bath Foil:

A wooden frame from thin planks is installed on the wall or ceiling surfaces with a cross section of 5 × 5 cm. Fixation of the slats is performed using self-samples. If necessary, the insulation is laid - mineral wool.
Foil sheets are mounted on the crate of a reflective layer inside the Vangest (18-20 cm) with fixation on galvanized nails or metal brackets. With a significant width of the material, its fixation is carried out not only at the edges, but also in the middle.
To prevent the deformation or rupture of the material, the joints are glued with a metallic basis.
The fixed foil is sewn with lining, while leaving the necessary technological gap of 1.5 cm for the right air exchange. This will provide the best thermal conductivity of the material and the qualitative reflection of infrared radiation in the room.
Fastening the lining is performed on a wooden crate set on top of foil. For this, a 2 cm thick layers are used with fixation on the self-tapping screw.

The thermal insulation of the pylons using foil reflectors allows to save up to 30% on raw materials for the fifumes, as well as extend the life of wooden buildings of modern baths, preventing rotting, the development of mold and pathogenic microorganisms.

Aluminum foil for a bath: What better to choose, characteristics and installation

The insulation of this type does not absorb infrared radiation, and reflects, effectively distributing it. Aluminum foil is distinguished by high thermal conductivity, therefore is a powerful heat reflector.

All the subtleties of the use of foil in the bath for insulation of walls and ceiling

The perfect bath implies a quick heating steam room and long coherent heat. To achieve this, you have to either put a log cabin with thick walls, or additionally insulate the walls with the ceiling. The second method is cheaper, but not all thermal insulation material is able to withstand the bath conditions. Traditional insulation will not fit, but the aluminum foil for the bath is exactly what it is necessary. However, there are your pitfalls here.

What is the fool from the foil in the pair: "Divorce" or indisputable benefit

Some argue that from the foil insulation in the bath is zero, and others are what is the perfect thermal insulator. Part of the masters are simply used by foil, and others prefer to combine it with thermal insulation material. Discussions are infinite, but you need to choose.

Principle of action of material

Heat in steam room is transmitted by:

On the one hand, the aluminum foil has a high thermal conductivity, but on the other - it reflects almost everything that falls on it infrared radiation.

The first moment often mentions opponents of this material. But they forget to say that the foil is able to warm only from the sheat or walls of the bath. First, the lining should be punished, and only then it will give part of the heat aluminum. The walls of thermal energy will be given the foil surface itself.

Important! The high thermal conductivity of the foil will play a negative role only if its square is a large suspension area. The lining case is not able to give a significant amount of heat due to the minimum contact between these two building materials.

With infrared radiation, everything is quite the opposite, just the most interesting thing begins here. It is him that they emit hot stones and stove in the bath. However, due to its properties, IR rays of foil almost completely reflects back to the room. Therefore, it is correct to call it heat reflector, and not insulation.

There is another nuance - a hermetically stacked foil layer is an excellent vapor polypoletor. As a result, the heated steam remains indoors, increasing the temperature of the bath air. The sauna is fastened faster, and after burning firewood cools slower.

Advantages of use

Among the advantages of the use of foil in the bath should be mentioned:

Lack of harmful discharge and hygiene.
The preservation of the coating with prolonged exposure of excessive moisture and high temperatures.
Simple installation.
Incompetence of rotting.
Enhance sound insulation.
Fire resistance and heat dissipation of material.

However, if the foil layer will have braces, then its utility will decline sharply. It's all about condensate. It will fall out not on the outer side of the foil inside the bath, but on the inner facing the wall. The accumulation of moisture will necessarily lead to the appearance of mold and rotting wood.

What folgized material is better to choose for a bath

In addition to the usual rolled foil, there are a lot of different foil materials intended for insulation of walls. But not all of them apply in the bath where high temperature and humidity. It is imperative to choose the right and harmless thermal insulator, otherwise the double room can lead to health problems. The additional layer makes foil more durable or increases its thermal insulation characteristics.

You can warm the bath:

kraft foil (on paper basis);
foil tissue (on fiberglass);
folgicone (on polyethylene foamed).

The first option is a complete analogue of standard aluminum foil, only with a hardening layer of paper. The second is the most durable and fire-resistant of all, and the third due to foamed polyethylene creates an additional layer of classical heat insulation.

Tip! Near the furnace to snew the walls and the ceiling of the bath, experienced masters recommend exclusively foil on fiberglass. It is durable, harmless and withstands temperatures up to several hundred degrees.

Polyethylene substrate calmly transfers heat steam room. But near the furnace, this foil material is not worth it on the walls. In the heat of a hot stove, he will inevitably begin to melt.

There are also fool-based insulation based on Minvati, but it is not recommended to use them in the bath. Some of them contain formaldehydes, which begin to stand out when the temperature is raised, while others lose all their thermal insulation properties during wetting.

Even the thick aluminum foil without a substrate during installation is fairly easy to damage. Its applying in the bath is only as a last resort. It is best to choose an option on fiberglass, manufactured in three types:

"A" with one-sided folging (operating temperature from -40 to + 150 ° C).
"B" with foil from both sides (operating temperature from -40 to + 300 ° C).
"C" with adhesive base and one foil layer (operating temperature from -40 to + 80 ° C).

All listed materials are sold in rolls of various sizes and thickness. They will easily lift under the desired size. And their mounting in the bath is produced by galvanized nails or stapler brackets.

Nuances of mounting foil and foil insulation in the sauna

The choice of foil thermal insulator depends on the material from which the bath is erected. In some cases, it is quite simple aluminum foil, and in other trimming it is recommended to be performed only using the insulation.

Option # 1: Frame Warming

If the walls of the bath are made of thick logs, then the casing of their foil is money for the wind. Here is more important than the quality of caulking, and additionally, it is easy to warm the logs. From the thermal insulation layer of the positive effect in this case will be little.

In the log sauna, the foil insulation is worth using only when the ceiling is trimmed. At the top of it, at least some sense will be, especially if the ceiling overlap is made thin and without a warming layer on top.

Also aluminum foil without a substrate can be covered with walls around the stove. Such a screen will reflect warm in the form of infrared radiation in the steam room, instead of spending it on a useless heating of the wall behind the heating.

When the ceiling is trimmed, the foil insulation is settled with a reflective layer of down, a mustache and small, at 5-10 cm, entering the walls. The joints are mandatory are punctured by special aluminum scotch. It is very important to create a sealed layer without the slightest lasers for steam.

After installing foil, you can leave as it is. So the condensate will not accumulate on it. But from aesthetic point of view it is better to cover it with a clapboard. To do this, you will need to fill the cave from the 40x40 mm bars, to which wooden planks will be born.

Option # 2: Brick or Framework

If the steels of the sauna are made of bricks or a framework technology is used, then it will be mandatory to insulate them with foil heat insulating material. Otherwise, heat in such a bath will not stay long.

The sequence of work in this case is absolutely identical to the technology used in the log cabin. Only the plating foil is performed in bulk throughout the area of \u200b\u200bthe walls and the ceiling so that there is a thermos. You need all possible ways out of heat to overlap to the maximum.

Tip! Special attention in thermal insulation bath using aluminum foils must be given to windows and doors. The stacked material should be reliably nourished to the shoals and sneak tape.

Ideally, the crate under the lining should be made independent, with a gap between the frame and the foil. The more spaces, the better the ventilation and less condensate. And this is the most important point in the insulation of the steam room.

According to the technology, the foil walls with a ceiling in the bath receive reliable protection against moisture, and the foil coating works as a heat mirror, contributing to maintaining comfortable temperatures. You can insulate the bath yourself, there is nothing difficult in this matter, you only need to consult with a specialist in choosing a heating substrate.

Foil for thermal insulation Baths: What to choose and how to install

Will there be in the Ban from aluminum foil. What a folgized insulation is better to choose for a bath. Mounting foils in a steam room.

What a aluminum foil for the bath is better suitable

The perfect bathing construction should warm up as quickly as possible and a long time to maintain thermal energy. For this wall and ceiling in it insulate. Such a thermal insulator as an aluminum foil for a bath is one of the most sought-after materials, since it is distinguished by resistance to high temperatures and humidity.

Properties Foil

Among the characteristics with which the foil and sauna has the most important ability to reflect about 97% of infrared rays. If a solid covering of steam room is performed by this material, thermal energy will be maintained as much as possible. The fact is that IR rays are not absorbed by the walls, but are reflected in the direction of the room.

Foil foil is perfect because:

the material is able to withstand temperatures up to 300 degrees and even higher - this property depends on its type;
does not emit substances harmful to the human body;
it has a small proportion.

In addition, the aluminum foil has such advantages:

moisture resistance;
plasticity;
durability;
countertilebility;
resistant to corrosion processes.

When using this material, almost all heat remains in the steam room, at the same time the insulation for a bath with a foil on the walls will be securely protected from condensate. The fastening process is not relieved, the main thing in work is not to allow deformation, and there is no gaps between the canvas.

To achieve a larger effect, foil insulation for the baths are not alone, but also the ceiling surface, because pairs and hot air are first rising up.

Rolled aluminum foil

Foil is produced, both in rolls and sheets. Roll material can have a thickness from 0.007 to 0.2 millimeters, 10 -1500 millimeters width. The percentage of aluminum content in it - up to 99.5%.

Depending on the type of surface of the foil happens:

smooth, not having additional finishes;
under the finish;
finishing.

On the scope of application, the material is divided into the canvas:

Depending on the manufacturer's method, foil is distinguished:

soft (annealed), having marking "M";
solid (unnecessary) - she is assigned the letter "T".

Quality products are called a canvas that there are no folds, stains, donkeys and other inclusions on the surface. When viewed on the lumen of a thin canvase, it must have cuts and the smallest holes. In total foil, the presence of a small number of holes is allowed, which is regulated by the technical parameters of the equipment used.

The thin canvas is wound on the sleeves having a different diameter. Thick foil is produced in sheets.

Before starting work on insulation, developers are interested in how much foil is worth the bath. Rolled products of domestic production will cost cheaper imported material. With a roll length of 25-30 meters, the price will be approximately 20-30 dollars.

Using foil for insulation bath

To determine which foil is better to use for a bath, you need to consider what material the structure and conditions for its operation are erected. If the construction is logged with carefully cocked walls, then the foil heat insulator is not required.

In the case when the bath is built out of natural wood, but large in the area and warms well, experts recommend to sew the ceiling and walls from the inside of a thin foil, and then close it with lining. You can apply a foil cloth for the surface behind the heating unit, with the result that the pair will warm up faster.

Despite the fact that the bath building from foam concrete is considered warm, it requires high-quality vapor barrier, so the use of foil will be justified, but it is better to stop the choice on the combined products.

Frame and brick buildings need to warm up. For this, insulation are perfect for a bath with foil based on polystyrene foam and minvati. The type of this material is chosen for ceilings, taking into account the thickness of the overlap and absence / availability of the insulation of the attic.

In addition, the operational conditions are important. If the bath enjoys infrequently and accept procedures for a short time, there is no need to warm it with foil. When the steam room is often used and there are for a long time, high-quality heat insulation will save fuel, and the room will quickly warm up and cool.

Fulfillment of simple bathing

When the walls of the bath buildings are trimmed, the foil canopy is attached to the surface or on top of the heat insulation layer. Such work will take little time and does not require great effort.

The process is as follows:

Before you have a foil bath, a frame made of wooden planks fix on the wall.
The insulation is placed between the rails.
The top of the heat-insulating material is covered with the foil of the mustache, the joints between the stripes are sampled using aluminum tape.
Foil is chosen by clapboard and be sure to make a 15-20-centimeter air gap between her and the foil surface. This is a prerequisite for efficient heat transfer.

The air gap will reduce the thermal conductivity of aluminum, and since the hot lining will not touch the foil, then the direct heat transfer will be impossible due to the insulating quality of the air. At the same time, infrared rays falling on the surface of the foil cannon will sing towards the parley.

Types of insulation with foil for bath

In the process of work, the thin soft web of the foil is easily frozen and rushes, so new technologies have appeared.

Now available:

Foil paper

Other its name is a compatible foil on a paper basis for a bath. It is elastic and tight material and is characterized by excellent vapor barrier characteristics. It is released two types: foil plus kraft paper and foil plus paper plus polyethylene.

Foil paper is able to withstand 130-degree heat. It has resistance to compression loads. It holds the form and easily cuts. Standard bandwidth is 120 centimeters. For its attachment, self-tapping screws, construction brakes and nails are used. The material is used to cover a bath from the inside. It is not recommended to use a cascated foil for the surface of the walls adjacent to the furnace.

Folotkan (foil fabric)

This soft two-layer material is made of fiberglass and foil. Volumecan thickness is in the limit of 0.12 -3 millimeter. The canvas need to fix the jack. Foil tissue is used to insulate the room bath, it is possible to sow walls near the heating unit.

Its main characteristics:

the ability to withstand temperature up to 500 degrees;
resistance to mold and other harmful microorganisms;
good moisture resistance.

Foil polystyrene foam

The insulation is made on the basis of polystyrene and covered with the finest layer of aluminum foil. We produce material in sheets of 1.2x0.6 meters thick 2-10 centimeters. Apply in order to insulate the premises of the bath building from the inside. The sheets are equipped with stepped locks that prevent the formation of cold bridges.

Foil polystyrene foam has the following qualities:

not absorb moisture;
reflects about 98% of thermal energy;
features vapor insulation properties;
resistant to chemical impacts;
safe for health;
has a long service life.

Foil polyethylene foam

This rolled insulation thickness from 2 to 10 centimeters has one-sided or bilateral foil coating. It is used in the arrangement of thermal insulation of interior baths.

This material is able to withstand the temperature of no more than 100 degrees. It is not used to cover the surfaces located near the oven.

Fungalized Minvata.

It is produced in rolls or in the form of mats of different thickness. It has excellent thermal insulation qualities. Ideal for insulation of frame bath buildings. The use of rolls or mats with foil makes finishing work easier and comfortable.

Best Bath Warming Material

Since the cost of energy is constantly growing, the hosts of the bath and saunas are forced to look for ways to save the cost of exploitation of the steam. When erecting a new building, it is necessary to apply materials with heat-saving characteristics. In additional protection against heat loss, the baths erected from bricks, foam concrete, slagoblock and other building materials, except natural wood.

Especially carefully at the arrangement of the steam, the wage should be approached by the issue of which foil is better for the bath, since the material should be environmentally friendly and well reflect heat. All these requirements are responsible insulation, having a foil aluminum coating.

Pluses of foil insulation:

The material is universal, since it is used for walls, ceiling overlap and floor of the bath.
Foil coating insulation have a good lift.
Products are produced in a wide range.
They are used in wet premises, while they do not need to be treated with fungicidal compositions.
High hygienic indicators have. Aluminum properties do not create a nutrient medium for rising fungus and mold.
They are not deformed and not melted in the steam room in conditions of elevated temperature.
The material is convenient in operation. It is easy to assemble and fix on different planes: vertical, horizontal and inclined.

Tips for insulation baths:

If the bath building does not have a commercial destination, there will be enough decoration of the walls of a 3-millimeter foil in rolls.
For commercial enterprises, solving the problem, which is better to choose a foil for a bath, will be the use of cashed products on a basalt mineral basis.

When insulating a bath, located inside the capital building, you need to take into account the functioning of central heating, as it warms the air additionally.

Aluminum foil for a bath: what better to choose, whether to use on a paper basis in a sauna and steam room, foil insulation, how to stripped walls

Aluminum foil for insulation bath: thermal insulation myth or ingenious reality?

Ideally, the bath must quickly warm up and long retain the resulting heat. For this wall and ceiling are trying to isolate high quality, connect all outputs outside the steam room. The traditional insulation layer has a complex structure, but almost always the constant component is an aluminum foil. This component is also popular as ambiguous. Philosophical battles, supported by the theory of physics textbooks, are underway on the forums of baths for more than one year. Some argue that foil is a wonderful insulation for a bath, others - it is practically useless as the heat insulator. Where is the truth? Let's try to figure out.

Aluminum foil: the next "divorce" manufacturers?

Aluminum foil for insulation bath is a thin (average 30-300 μm) aluminum layer, which is used in a constant form or in combination with kraft paper, fiberglass, rolled insulation. The main argument of opponents of using foil in the bath is that aluminum has a high thermal conductivity.

Based on this, thermal energy can be easily passing through the metal layer and be outside the steam. In fact, everything is not quite so. First, the high thermal conductivity will "work" against us only in the case of direct contact of the foil with a heated body (for example, with wooden clapboard or block chamber). Secondly, in addition to thermal conductivity, there are other ways to transfer heat.

Three ways to transfer heat

Heat transmission can be produced in three different ways in nature:

In the case of Foil, it is worth considering only the last method - radiation. The furnace in a steam room during the extractor begins to intensively emit infrared rays that a person perceives how heat. Now the most interesting begins. Ik rays, falling on the aluminum layer of foil, do not absorb them, but are reflected in the opposite direction, that is, back to the steam room. Reminds the effect of the mirror. Therefore, we can say that the foil for bath is not a heatel in the literal sense of the word, it is more correct to call it the heat transferser. And it reflects to 97% of all IR rays.

In addition, the foil is a vapor insulation - a hermetically material that does not transmit water or steam. Accordingly, it prevents the output of the heated steam and it also contributes to the preservation of heat.

At the expense of all this, the steam, sheltered by foil, is sleeping much faster and no longer cools.

Foil can be mounted directly on the walls of the bath or on the insulation layer (basalt cotton wool, glass gamble, etc.). The last option is more efficient and most often used as a traditional insulation of "pie" in the steampers.

The fact is that the foil is able to reflect not all heat. Part of it, due to the high thermal conductivity of aluminum, goes on. In order for it not to go beyond the wage, the heat insulating material is fixing the foil layer. High-quality thermal insulation "cares" what foil missed, and sends it back.

This is especially important in frame, brick, concrete baths and saunas. Without good thermal insulation, bring such a bath "before the condition", especially in winter, problematic - the lion's share of thermal flows emanating from the furnace will immediately be carried away through the walls on the street. But good Russian bathrooms with a real brick furnace in special thermal insulation, except for caulking, do not need.

Bath trim foil: how to do it right?

In order for the aluminum foil to perform all its functions assigned to it by the manufacturer, you should know how to fix it correctly. In this case, there are some nuances, the non-fulfillment of which reduces its heat-reflecting and vapor barrier properties to zero.

The process of skin simplifier looks like this:

A frame of wooden slats is mounted on the walls of the bath, between which the insulation (rolled or slab) is laid.
Foil foil on top of the insulation on the plank. All joints are carefully sampled with special scotch - for tightness.
Foil is sewn with lining. It is very important that the air gap of 15-20 mm is settled between the aluminum surface and the lining. This will not allow the high thermal conductivity of aluminum to manifest themselves completely. The heated lining and the foil will not touch, and therefore the direct heat transfer will not (the air is a good heat insulator). At the same time, IR rays that have come down to foil will almost fully reflect the back.

Such an insulation "Pie" using foil is arranged on the principle of thermos. Simplified, thermos is a double-lit flask with a vacuum layer between the walls. The mirror layer is applied to the inner surface of a smaller flask (of which the heated liquid comes into contact). The vacuum prevents heat propagation by means of thermal conductivity, and the mirrored layer is by IR radiation. The same processes, only with a lower degree of intensity, occur in a foil insulation layer. At the same time, the role of a mirror reflecting surface plays foil, and the role of a vacuum with a very low thermal conductivity is the material of the heat-insulator located behind the foil.

Thus, using foil as part of the insulation layer of walls and the ceiling of the steam, it is possible to significantly reduce the time of the battery, longer enjoy the concentrated steam and heat, save the amount of wood or electricity.
