Insulating the ceiling of a bathhouse is an old-fashioned way. Heat conservation in a wooden house

Today, many people are building bathhouses on their property. It is clear that it should be as warm as possible. If the owners do not want to get an unsuitable design, then they should think about every moment at the planning level. But when creating a full-fledged bathhouse, you can save a lot on firewood.

What should you think about? Insulation of a bathhouse ceiling is important stage in construction. There are enough proposals for materials on the market. Before starting construction, it is worth considering any action. After all, each material has its own characteristics and fastening technology.

When can you not do without insulation?

According to experts, it is not necessary to insulate the ceiling in a bathhouse with your own hands in every case. There is a law of physics that you should not forget: warm air rises up. The ceiling restricts the movement of heat, and it accumulates there, without benefit. In this situation, it is important what level of thermal conductivity. In the absence of an insulating structure, about 30 percent goes to the street.

Depends on the season

Some note that for a bathhouse flooded in summer time, there is nothing wrong with the lack of insulation. If this building is used all year round, then you will have to think about insulation.

In addition, if a person does not want to heat all day, it is also worth completely eliminating heat loss. This can be done without the involvement of specialists. Since insulating the ceiling of a bathhouse is a simple process, all that remains is to take full instructions into service.

Several methods to choose from

As already noted, there are plenty of ways, you just have to choose your own and implement the project. How is the choice made? This is influenced by what is above the ceiling:

Despite this, there are limitations to the work. Experts identify several main areas:


As a result, each procedure gives the main result - insulation of the bathhouse ceiling. You can complete this operation with your own hands in a couple of days. Before you begin, you should understand the effectiveness of each action, the preparation of material and tools required in the work process. Having understood the nuances, you can begin installation.

Flat ceiling

During the work process, you will need several component materials - expanded clay, clay and sawdust. When present cold attic, but you don’t want to insulate it, then it’s worth thinking through some points. The flooring option is the most suitable for this design.

This is a simplified construction - since there are no loads on the ceiling, strengthening the beams is not required. The rough structure will lie directly on the harness. From the name of this method it is clear that an embankment will be produced. Therefore, it is worth laying the block with a thickness of at least 4 centimeters to prevent collapse.

What should the layer be?

Any materials available to the owner of the building are used. But the principle is the same. This is a “pie” with several layers. The bottom-up overlay goes like this:

  1. Finish ceiling.
  2. A layer of vapor barrier material.
  3. Boards.
  4. Wax paper.
  5. Insulation layer.

Vapor barrier

It must be said about Its function - it is not only protection from steam, but also the ability to withstand high temperatures. There is not a wide range of such products on the market, so choosing will not be difficult. Many people think that foil is the best option.

The insulating layer is made of expanded clay, clay and straw. If this is a modern flooring, then to prevent component elements from spilling through the cracks, paper (necessarily waxed) is used. The thickness of the coating reaches 30 centimeters. This is quite enough to ensure maximum protection and prevent heat from escaping outside. Expanded clay of various fractions is available for sale. It is important to lay it so that no voids are formed. This is the only way to insulate the ceiling in a bathhouse with expanded clay with your own hands.

Some craftsmen additionally fill the surface with boards of small thickness (for separation.) But there is no great need for this.

Clay and other options

The next type is the use of clay. It is initially soaked and then mixed with straw or sawdust. Insulation of the ceiling in the bathhouse is done when a homogeneous composition is achieved. Afterwards, the resulting mass is distributed around the perimeter of the insulation zone. There is another option: you can dilute the clay, place it over the entire area, and let it dry for four days. Afterwards, repair the cracks that appear with the same solution. Sprinkle sawdust or oak leaves on the surface, up to 9 centimeters. The final layer is 5 centimeters of dry clay.

From the bathhouse side (to rough ceiling) vapor barrier material is installed. The joints are sealed with construction tape. Afterwards the lathing is made, and the ceiling is already installed on it. This could be a forcing or just a chopping block. The choice will depend on the financial capabilities of the owner.

If both of these options are compared, then there is one common disadvantage. That's a lot of weight. This means that the ceiling should be made of thick boards. The advantage of this method is that it is inexpensive. starting materials. A good option Do-it-yourself insulation of ceilings in bathhouses with mineral wool. Expanded polystyrene is also often used. But such materials will not be cheap.

What should you prepare?

During the work process, it is worth preparing the necessary raw materials and tools. This:

  • Construction stapler.
  • Saw.
  • Hammer.
  • Boards.
  • Foil and wax paper.
  • Metal tape.
  • Nails.
  • Expanded clay or clay.

Before purchasing insulation material, it is worth making a calculation so as not to spend too much and provide maximum protection.

false ceiling

Create such ceiling insulation in a bathhouse with cold roof not so easy. This is required for those who wish to create a room on the erected structure. If there will be a living space on the second floor, then it is worth making the floors reliable and complete. Afterwards the ceiling is already finished. Before starting work prepare:

  • Construction stapler and tape measure.
  • Hammer and saw.
  • Sharp knife.
  • Mallet.
  • Beams.
  • Foil.
  • Metal tape.
  • Nails with protective layer.
  • Laths for sheathing.
  • Lining or other finishing material.
  • Insulation.
  • Edged board.
  • Vapor barrier film.

Before purchasing, you should calculate the amount of insulation for the bathhouse ceiling. If the bulk method is chosen, then the calculation is made based on the height and area of ​​the ceiling. Do not forget about the climate indicators in the region. What the insulation will look like from bottom to top:

After preparation necessary materials and the required tools, the process of performing the work begins:

  • First you need to lay the floor beams.
  • After which the vapor barrier is fixed to them from below. To do this, purchase foil. To completely eliminate the passage of air, it is worth sealing with metal tape. It is good to carry out such work with a stapler.
  • To ensure that steam does not accumulate, the slats are fixed and a gap of 3 centimeters is made.
  • For finishing it is better to use lining. But such material is not cheap, so if desired, you can replace it with something.
  • Next is to climb into the attic. It is laid between the beams insulation material and vapor protection. But what to choose? It is good to insulate the bathhouse ceiling basalt wool.
  • Afterwards it is worth laying a layer of waterproofing. If we're talking about about a bath, it is better to give preference to a membrane.
  • Next, edged boards are used, everything is hidden under them. Since this part will become the floor for the second floor, you should not use concrete. It's heavy.
  • Flooring is carried out as a finishing material.

The process is not complicated and anyone can handle it. You should not skip any of the stages, otherwise the design will be unreliable and will not create additional heat.

How to insulate a panel ceiling?

Masters say that such a design is rare in a bathhouse, because it is difficult to work with. The fact is that you need to mount a pallet into which the main materials will be loaded. In your work you will need to use:

  • Hammer.
  • Saw.
  • Construction stapler.
  • Sharp knife.
  • Nails.
  • Foil.
  • Mineral wool.
  • Bars.
  • Boards.

To insulate the ceiling of a bathhouse with mineral wool, it is worth taking a thickness of up to 10 centimeters. The material is easy to work with, as it is cut with a knife, inserted and, if necessary, pressed. You need to install the pallet depending on the room itself, but the width can reach up to half a meter.

Knowing the length and width of the ceiling, you can calculate in advance how much it costs to purchase. There is no need to take extra. Sometimes mineral wool has a higher density. In such a situation, you won’t be able to compress it - you can only cut it. But these pieces can be used in some recesses. If the size of the bathhouse ceiling is 3.5 by 3.5 meters, then 22 standard mats will be enough.

It is clear that in the bathhouse the temperature rises greatly, so using any insulation will not work. Particular attention is paid to the place where the person will steam. The material must be:

  • Non-flammable. In case of fire, do not create smoke.
  • Capable of not reacting to temperatures up to 100 degrees.
  • Do not accept liquid.
  • Do not release chemicals into the air.

Find completely high quality and suitable material not so simple, because each has its own pros and cons. Therefore, you should base your choice on the basis of these data. How the work is going:

  • The new design is made first. To do this, you need bars or boards, the length of which can reach up to half a meter.
  • The bars are fixed at a distance of half a meter, and the boards are fixed to the fasteners perpendicularly. An indent of 4 centimeters is made from the edge.
  • According to external data, this is a box. The vapor barrier goes deep into it. Then it is fixed. This shield needs to be raised up. It is better to strengthen it so that it does not fall apart.
  • The created shields are placed close to each other on the roof.
  • The supports for such a structure will be the walls. It follows from this that their length should be identical. The insulation is laid in existing pockets. Next is the laying of the flooring boards and then the finishing floor.

Panel ceilings are used in two-story baths. It is compared to a hemmed one. As a result, everyone decides for themselves whether to save money on the construction of the structure. When installing a panel ceiling, you should not use plastic in the finishing. He is very afraid of high temperatures. So, a few hours after using the bathhouse, this entire structure can simply become deformed, ruining the entire interior of the room.

Conclusion

So, we found out how to insulate a bathhouse yourself. Before making the final choice of material, it is worth familiarizing yourself with the characteristics of each insulation. Only then will it become clear which is better. Some have increased flammability, which is definitely unacceptable. Builders believe that ceiling insulation should be planned at the level of building a bathhouse. And everyone can do this with their own hands, without the involvement of specialists.

Real estate and electricity prices are growing steadily. Construction corporations and ordinary people Those who want to build a house are forced to look for ways to reduce the cost of providing heat to their premises.

– one of the best solutions. To tell the truth, this is not a new thing at all. This technology has long been used by our ancestors. It was first remembered in Europe and the USA, when the issue of thermal efficiency of houses became an issue. You should not naively assume that a house made of straw will fall apart at any moment, as in the fairy tale about the three little pigs. Thanks to special technologies, such a house will last a hundred years to the delight of its owners.

In America, for example, since the mid-19th century they built thatched houses. This began because straw was a widely available material, but wood was in short supply. As soon as pressing machines were invented, building houses from straw became popular. After the advent of new construction technologies (mid-20th century), they forgot about straw, but not for long. The environmental crisis and concern for their health have prompted people to revive such construction.

has a number of advantages listed below:

  1. Excellent thermal insulation.
  2. Relative speed of construction.
  3. Cheap straw.
  4. Quite good sound insulation.
  5. Ecologically pure material- does not harm health.

If technology is not followed insulating a house with straw the following consequences may occur:

  1. Straw rotting at a moisture content of more than 20%. It is necessary to strictly monitor during construction to ensure that the straw is dry.
  2. Fire is very dangerous during construction. The straw blocks themselves, compressed special technology, resistant to fire. But, during the construction process there should be no fire on the site (even smoking is prohibited), because A few tufts of straw on the floor can cause a large fire.
  3. Risk of rodents settling in straw walls. To avoid such troubles, experts advise using rice or rye straw, which mice do not feed on.
  4. Although it is not expensive to build houses from straw, you must immediately have the funds for complete construction, taking into account the internal and exterior finishing. Such construction cannot be “frozen” and continued in a year or two.

Where to begin insulating your house with straw? First you need to purchase compressed straw blocks. It is very important that the pressing is strong and of high quality (otherwise there will be risks of fire). Next, the blocks are placed between the frame posts. Straw blocks are fastened with rods (both metal and wood can be used). The next stage of insulating a house with straw is processing the straw. As a rule, it goes clay-lime mortar or a mixture of clay and water. It should be applied in several layers.

Drywall covers the inside of the wall. For exterior finishing many options. The lining looks good. Thanks to frame technology a wall insulated with straw is quite resistant even to hurricane winds.

If the walls of the house are made of straw, then the roof cannot be constructed from very heavy materials. To prevent rain and snow from falling on the walls in large quantities, they usually make a cornice with a margin (at least 50 cm).

The positive thing about building walls from straw is that the foundation does not have to be massive, which speeds up and reduces the cost of the construction process.

In addition to the obvious environmental benefits, insulation of walls with straw is cost effective. Brick house with the same level of comfort it usually costs twice as much. Wood prices are also constantly rising, due to insufficient regeneration of the Earth's forest reserves. Straw, in fact, is a waste product that often rots. The price of straw bales mainly consists of the cost of baling the straw. The cost of the material is scanty. It’s worth thinking about why, despite a number of advantages, straw houses have not replaced other construction? The answer is simply simple - it is not profitable for someone, namely corporations that produce expensive building materials. So, before enriching someone's pockets, you should study the pros and cons in detail. And choose a house made of straw!


When arranging a cottage or country house The task of building a bathhouse often arises. The classical bathhouse has developed a number of specific traditions that go back to ancient times. Previous generations created proven construction and finishing technologies. Thanks to these techniques, the bathhouse has unique healing properties. Today we’ll talk in more detail about how insulate the bathhouse ceiling.

Ceiling insulation

During construction baths, installation and insulation of the ceiling is considered one of important points. What affects the ceiling? In the process of using the bathhouse, it undergoes a number of aggressive influences. Conditions are created inside the steam room high humidity and air temperature. Hot steam rises to the ceiling, and if there is little heat transfer through the ceiling, the space inside the bath will not warm up, and bathhouse will not serve its intended purpose. There are many ways to insulate ceilings, let's look at some of them.

The old way insulate the bathhouse ceiling

A solution of about 5 cm of dough-like clay with the addition of chopped rye straw is spread on the tongue-and-groove boards from the attic side. After drying, the clay cracks. This dried layer is rubbed with a solution made of clay and sand. When both clay layers are dry, a sand cushion 10-12 cm thick is poured on top. The clay-sand layers are used for absorption excess moisture, which is formed from wet steam. Thanks to high temperature In the bathhouse, when there is no steam, the clay layer dries and retains heat in the bathhouse.

Backfill method

Tongue boards are nailed to the beams. They need to be oiled. A layer of boards with moisture gaps is attached to the tongue and groove boards. A layer of waterproofing is laid on top. A 20 cm cushion of bulk types of heat insulators is poured onto the waterproofing layer. It can be slag, sand, or a mixture of sawdust and clay. A good option for this method of insulation is backfilling with expanded clay granules.

Combined method of insulation bathhouse ceiling

The ceiling is covered with thick boards, the thickness of which is 7 cm or more. A vapor barrier is laid on the boards (waxed paper, dry cardboard, foil). Then a pillow is made of soft clay, on which a 15 cm thick insulation is laid.

Various organic and mineral heat-insulating substances are used as insulation. For example, sawdust with clay, expanded clay, modern mineral fibrous materials. A sand-cement screed is made on top of the thermal insulation, and a flooring is made on top. On mineral wool additionally lay film or fiberboard sheets.

Combined method with sawdust

Two layers of boards are screwed to the beams using screws, the first layer consists of edged boards, and the second (with inside) – finished lining made of aspen leaving gaps. Cardboard is laid on top of this structure from the attic side, and a 2-5 cm layer of clay mixed with sawdust is placed on top of it. Next layer – 15 cm basalt insulation. This whole “pie” is covered with film and attic boards.

On the modern construction market you can find a great variety of insulation materials made from jute, flax fiber and other materials. Good feedback There are reports of jute felt, which does not emit harmful substances.

There are several ways how to insulate a bathhouse ceiling. I will be glad if I helped you with advice.

A warm room in winter is much cozier and more comfortable. Although wooden beams and logs have excellent thermal insulation properties, there are vulnerabilities, requiring additional thermal insulation.

Construction wooden houses has its own specific features, one of which is the insulation of walls, floors and ceilings.

Why additionally insulate a wooden house?

Wood contains a large number of moisture, which evaporates over time. At the same time, the geometric shape and dimensions of the logs from which the house is built change.

Previously, moss was used to seal cracks between logs. With the advent of new insulating materials there was an opportunity to do this in other ways.

What and how should be insulated in a wooden house?

IN wooden building additional insulation require:

  • walls;
  • ceiling.

The floor is insulated with a layer heat-insulating material, placed on top of wax paper or waterproof film used as a waterproofing.

If the house has a basement, then film or paper is spread over the ceiling of the basement. If the house is on the ground, the waterproofing is laid on the base slabs.

We insulate the floor

The thicker the insulation layer, the less heat will escape from the house through the floor. The plank floor is laid on top of the insulation.

See more details:

In addition, the so-called system is currently becoming popular in wooden houses. warm floors:

If the house has an attic, then insulating the ceiling is done in the same way as insulating the floor. A layer of hydraulic insulation is laid on the attic side, on which insulation is laid.

Insulation of the attic floor

Wall insulation wooden house produced by two methods:

  1. outside;
  2. from the inside.

When the main temperature change occurs in the facing layer. Wherein wooden structures are in more favorable conditions. Temperatures inside the house and from outside logs (if available external insulation) differ little.

External insulation of a wooden house with polystyrene foam

External insulation is carried out mainly by finishing a wooden house different materials- clapboard, brick, lining aerated concrete blocks etc. Between outer wall and a layer of insulation is laid over the cladding.

When covering a wooden house with bricks, it is necessary to leave between wooden wall and a brick gap for ventilation. This will ensure timely removal of excess moisture and protect the wood from premature aging.
Aerated concrete blocks can be laid without a ventilation gap. They have greater vapor permeability than wood, so excess moisture is quickly removed.

See more about methods of external insulation:

In winter, a wooden wall is exposed to high negative temperatures. This contributes to conditions that adversely affect the condition of the logs.

Insulating a house from the inside with mineral wool

Excess moisture can accumulate between the insulation layer and the wall, which leads to faster aging of the wood.

  • See more details: .

The insulation method is the same: on wooden wall waterproofing and a layer of thermal insulation are applied. If the house is insulated from the inside, the environmental friendliness of the insulation must be more high requirements than with external thermal insulation.

Decorative finishing on top of the insulation can be done with boards.

Also, which may not seem so obvious, sometimes it’s a good idea to insulate the roof and foundation. Cm.:

If you want to keep warm in wooden house, the owner should decide what he wants to have as a result. Internal insulation saves appearance wooden house, stylized as antique. External insulation gives the house a modern appearance and does not affect the beauty of the interior.

Lunarman, reading your posts, it is logical to draw only one conclusion - you are a seller of insulation materials, such as mineral wool and other nastiness in terms of ecology + high cost, or a firefighter who suffered from extinguishing “bare” sawdust
Here on the forum people mixed sawdust with binder and set it on fire and did whatever they could with it, but such material is not afraid of anything, so your negative opinions about sawdust as an insulation material are “like peas against the wall.”
No, I’m not a salesman, I just use my head sometimes.
What is "sawdust with binder"? With clay, perhaps? That’s what I said above, that previously double-insulated floors were done this way (but not ceilings - what’s the point there?).
As for the fact that “such material is not afraid of anything,” this is for the time being. Even fire-retardant impregnations do not make wood forever non-flammable - over time, all this chemistry can be neutralized.
Do you believe in miracles, like non-combustible sawdust? If they become non-flammable, then they will obviously lose their properties (hygroscopicity and low thermal conductivity).

Now I’m wondering about mineral wool, the second person is already talking about it. What kind of “bad ecology” does it have? Basically, tell me, what do you think it consists of?
Mineral wool is not good for walls - you need to nail it or press it down, otherwise over time there will be voids at the top, but the topic is about the ceiling.
As for the “high cost”, it’s also strange to hear. Any "Ursa", etc. It’s not really worth it, to be honest. Rockwool is more expensive, of course, but also, in my opinion, a relative trifle.

How much fireproofing impregnation did you use?
I lived my whole life in wooden houses with the ceiling and floor insulated with sawdust; in these houses there were stoves... They were and are warm, although there was no mineral wool. All of these houses were more than 20 years old, except one...

I think that mineral wool will not add any value to the house wooden properties fire protection, for some reason. But properly executed wiring, a good chimney and a working stove will give some confidence)

First of all, I didn’t insist on mineral wool. He said, at least take the slag (from us an old house at the dacha from the previous owner and was covered in the attic with slag, but not with sawdust, of course).
And you don’t see the difference between a board-log and sawdust, or what? In terms of fire safety?
And mineral wool for the attic between the floors is just that. It won't slip anywhere, won't get wet anywhere. And thus, thermal insulation properties won't lose. Mice, of course. Well, then pour expanded clay. Or the same slag.

I have a workshop built in the 1950s with insulation on the ceiling - sawdust with clay
They stand for about 60 years. It’s warm.
does not cake, does not burn, no antiseptic is needed. This is how we insulated our floors and ceilings in the old days. It’s better to mix the clay not with sawdust, but with chaff
It was not about sawdust and clay. I talked about sawdust and clay right away. Only this is already the Stone Age, and mainly for the floor. And not that warm, by comparison. I lived in a house where the floors were insulated with sawdust and clay, and in a house (now) where they were insulated with expanded clay and mineral wool. Two big differences.
If we exclude fire from chimney(slag, cutting, etc.), then how will sawdust, for example, ignite? Just wondering.

There could be a lot of things. Everything in the attic is like gunpowder. The beam will pass through the defective glass, focus, and a spark from some pipe will jump out through the microhole. You never know. Why is all this needed? Sawdust essentially turns into tinder over time.

That's right, I have a similar situation. Yesterday I went to the attic of the bathhouse and dug up sawdust and took pictures. Sawdust like new, not an ounce of dampness.

Dry, that is. Oh well.

"Sawdust-in-the-attic-bath." Surrealism, gentlemen, one word.
Moreover, bathhouses are not even particularly insured by insurers. In any case, ours do not insure (Moscow region, south).

If there weren’t so many people here defending these sawdust in the attic, I would never have believed that this could happen. So we were surprised, in one word.
