What windows are better - plastic or wooden, consumers are conceived when designing housing or repair planning. Installing windows is performed on what to serve they will be more than one year. Therefore, there is nothing surprising in the fact that all the characteristics of the materials are subject to careful analysis. The decision-making is largely dependent on the cost of a plastic window or wooden with similar characteristics.
Ecology
As for such a characteristic as environmental friendliness, it is worth noting that many confuse it with naturalness. In fact, the ecology of PVC compared to wooden frames will not have a big difference. Polyvinyl chloride window blocks are recommended by sanitary organizations to use in children's institutions, hospitals, while wood frames coated with special protective substances and varnish can be harmful to metal-plastic structures.

Hello, dear friends!
My name is Dmitry, I work as the head of the client department in the company "Just windows". As you already guessed, tell me in my blog exactly about the windows. And in the windows I understand.
Offers on the window market are a lot: what no! And there are not so many areas where the price variation on the same order would be so great as in the windows. And this is if we talk about honest companies. About dishonest and how to recognize them, I will definitely tell you in detail. The essence of my blogs I am going to reduce to one: how to understand which windows you need, how to recognize truly useful offers from advertising "chips", and choose the best option in terms of price and quality ratio. With all this, we will destroy marketing myths) I hope it will be interesting and informative.
So, proceed. Let's start with the fact that you still choose: plastic windows or wooden windows? A lot of articles are written about this topic. But the thing is that they write their marketers or a company engaged in plastic windows, or their rivals - "wooden officers". Well, and, by itself, marketers are very far from building physics and from practical experience. Well, and I have knowledge in these directions - even eliminate. At the same time I will try to maintain neutrality and objectivity of estimates.
Plastic windowsI think everyone is quite clear, because at present it is the most common option. These windows are made of polyvinyl chloride (PVC). Naturally, there are various stabilizers, pigments and so on. Many believe that it is non-environmentally. But sure, not to find a single cheer who would think the same. Because all these materials strictly comply with all SanEpidemiological standards, gta stamps, and other. However, to eat plastic windows in food or smoke, I still do not recommend, but I think you were not going to do this)
Small nuance. Windows is positioned, like German, English, Austrian and god news what. It does not matter. Absolutely all PVC profiles are produced in Russia. There are, of course, the same rheuu diamond or a geneo, which many positions as brought from Germany itself. I know only one company that brings the Rhuau Brilliant from Germany, but also the price of them will reach about 25 thousand per square meter of the window. And I know many companies that deliberately enter the client misleading, just cheating. Even can make linden certificates.
Nothing terrible, of course, no, that profiles are made in Russia. But each positions the profile in its own way. And this often occurs with loss in quality for the purpose of cheaper. Therefore, the company that will implement your order to life must be chosen very carefully. About this, I think, will be the next post.
It is much more difficult to all with those windows that are made of wood.
They can be divided into several types: old Soviet (carpentry); new cheap (such sometimes put in new buildings); Wooden eurowindows; Swedish; Finnish.
Old Soviet windows probably saw everything and many have so far stand. They stand at some decades. Clelli then build! But everything comes an end and they should also be changed.
In new buildings, it is sometimes quite rare, put wooden windows with a glass of double-glazed windows and fittings, a modern sample. The quality of the tree and processing is simply disgusting. I myself somehow lived in a student hostel-new building with exactly the windows. Cold winter, then hot summer - and the windows shied incredible. The gaps such that little birds did not fly. This option is even worse than the cheapest plastic windows from the developer.
Wooden eurowindows. It is precisely what they mean when they ask: what windows are better-glossy or wooden.
According to the principle of action and on the arrival of the sash with the frame, such windows are similar to plastic. Double-glazed windows are installed there. Different with a profile material only.
Such windows are made of three-layer glued bars of various, usually valuable, tree breeds. (Pine, larch, oak). You will not find exact technical specifications, such as sound insulation or heat transfer resistance. Each case is individual. But, about these two indicators, these windows correspond to the average class of plastic windows.
Everywhere they write that such windows "breathe" and environmentally friendly. This is pure marketing. Nothing there is not breathing there - this is not just an unprocessed array of wood, it is a three-layer glued bar. Which is carefully treated with aseptics, protection against fire, color and so on. Ecology here is dubious, it is like if inside the profile from PVC insert a wooden bar.
Stand these windows 3-4 more expensive plastic.
It would seem then: why are they generally needed? But, for example, in Germany, where plastic windows have already been stood everywhere in the 70s, it is precisely wooden eurowindows for replacing. Here, of course, it is worth the amendment that in Germany with quality everything is in order, and we can and deceive. Not so easy to distinguish the usual pine near Moscow from the Siberian larch. Although, perhaps, in 20 years, plastic windows will be perceived as the Soviet carpenter now.
Well, while the wooden windows are the image of the image. It is expensive, it is cool. It's like inset in Torpedo in Maybach from Karelian birch. Otherwise, they are definitely not better than many plastic. At the same time, care is demanding more thorough.
Well, now let's go to the exotic) Swedish windows. Sweden Country where obviously not fools in natural conditions with a climate like our. Therefore, the windows are really cool with them) if we talk about eurowindows of ordinary, then the principle of construction is about the same as PVC. Everything is clear here.
The Swedish windows have another design. There are two paired flaps. Inner (the one in the room) the flap is equipped with a single-chamber glass. And this sash is parenched with another sash, which is 10 less centimeters than internal. And there is no longer a glass pack, but a flat glass. The external flap itself is attached to the inner and can open to, for example, wash the windows. Is this design, by the way, does this design, by the way, are our joinery?)
It turns out that the frame there is a double: one for the inner sash and one for the exterior. It turns out more points of the frame and sash compared to the classic design. This, of course, is good) Plus it turns out a wide space between the outer and the inner flaps. The truth is not hermetically. And due to convection here it is difficult to say unequivocally good or bad that there will be a wide distance. But you can set the blinds there)
There is also I. finnish windows) They are almost the same as the Swedish, only the flaps are not paired there. That is, two separate sash. Otherwise - all the same.
The most, in my opinion, a significant difference between Swedish / Finnish windows from Eurocon / PVC is a wide box. Due to this, the slopes are free. Another big plus is more frames of frame sealing and sash. If the money allows you to have a very good option.
Well, and again about the price. Swedish / Finnish windows will cost 2 times more expensive than wooden Eurocon. At the same time in Russia, there are still few people doing this. Therefore, it is necessary to search in very large cities.
In general, the beginning is put. I will regularly add new posts. And this is still a pen test. All successful repair. And remember, in fact, the windows are not so difficult. I would even say, just)
Starting the conversation about which windows to establish, it is important to understand what we expect in the final result depending on the functional purpose of systems, our budget constraints and aesthetic preferences.
In the past 20 years, we see the trend when people began to massively refuse wooden windows, replacing them on plastic. 10 years old, as the tree again returns lost positions, but already a little in another interpretation.
The main dilemma facing buyers is wooden or plastic windows, which is better. Answer definitely on the assigned question is unlikely to take a self-respecting specialist, but to outset the main advantages and disadvantages of each of the options, perhaps.
So, today there are 3 types of windows:
- from an array of wood;
- from glued timber;
- metal plastic.
Having understood in the advantages and disadvantages of each option, we will be able to make your choice based on individual capabilities and needs.
What you need to know about wooden windows
Array of wood
The main material for such systems serve: pine, ash, beech, oak, maple, ram. This is most often solid trees that are less susceptible to mechanical damage. If we order such a window, and do not buy ready, we will have to wait for some time, since each element of the frame will be cut on the saws and processed separately.
Window from the array of wood
In order for the window to be qualitative and served a period of time - it needs to be treated several times with special impregnations that prevent rotting, infection with fungi, insect damage. After that, only beats, priming and varnishing. Naturally, such windows will be in a penny and will need a lot of time.
Glued bar
The windows from the glued bar are essentially different from the analogues from the array. Bar is thinly chopped, glued strips (lamellas) obtained by picking raw materials. The material varies with the amount of lamellaes per unit: three and five, from which its thickness depends.
Bruce window
Time for the manufacture of such frames is required slightly less and the cost will be more democratic.
If we talk about the quality characteristics of wooden windows, it is worth paying attention to their advantages and disadvantages.
Benefits of a tree:
- the tree is an environmentally friendly product, safe for allergic and asthmatics;
- durable and durable;
- has a high indicator of noise and thermal insulation;
- provides natural air circulation;
- maintains constant temperature regime;
- provides a normal level of humidity in the room;
- it's just beautiful.
Disadvantages of wood:
- change in the amount at different times of the year;
- high price;
- labor complexity;
- production duration;
- flammable material;
- complexity in care (compared to plastic windows, but this later).
So, wooden windows, whatever option we choose, an array or glued bar, it is beautiful, and practical, and safely in terms of ecology. The main thing is determined with the view of the tree and order the manufacture of a good joiner, which will qualitatively perform its work.
Plastic windows
Plastic windows are known to us as PVC (polyvinyl chloride). This is a relatively new material used to produce plastic structures and stretch ceilings. Today, PVC technology has strict quality standards and sanitary and hygienic standards that control and prohibit the presence of heavy metals in the alloy, such images protecting consumers from poisonous and chemical evaporations that harm their health.
Plastic window
Since the 80s of the last century, a ban on the use of lead and zinc was introduced in the manufacture of a polymer profile, a less toxic chlorine came to replace them, the pairs of which begin to stand out at a temperature of + 270 ° C and higher.
Benefits:
- durability;
- complete sealing of the room;
- ease of construction;
- lack of restrictions in form;
- ease of care;
- complete noise and sound insulation;
- the ability to install the upper turning mechanism;
- protection against insect penetration into the room.
Disadvantages:
- the possibility of the appearance and reproduction of mold;
- lack of natural air circulation;
- the formation of condensate due to violation of convection;
- no possibility of correction of mechanical damage.
What is the result? Plastic windows Modern option of a wooden analog. They are easy to operate, are rapidly manufactured and suitable for any size and features of the design. They may have protection against children, the anti-burglar system, do not burn and do not change their sizes depending on weather conditions.
Secure windows
Choosing which windows are better, wooden or plastic, manufacturers' safety manufacturers are not less important to consumers.
Secure windows
We have already sorted out in the material from which there are windows, now it remains to understand what secure windows are presented. When choosing safe options, it is important to carefully choose not only the material for the manufacture of the window block, but also pay attention to the glass and accessories.
The glass is not a set of glasses in the frame, it is a hermetic space filled with gas, which performs the function of heat and sound insulation, prevents the output of heat into the street, which is especially important in the heating period.
Choosing that it will be the main material of the window, wood or plastic, you can stay on the combined version, when the windows are inserted into the wooden frame, in this case the disadvantages, and the advantages of the systems merge together. We get an environmentally friendly product, we maintain natural ventilation indoors, protecting ourselves from the sounds of the street and reducing heat loss during the heating season.
Wooden windows for a long time no longer as before. The introduction of innovative production technologies made it possible to eliminate most of their shortcomings. Now they can adequately compete with a plastic regarding durability, practicality and functionality. At the same time, Euro-windows are still beautiful and safe. Let's consider the features of wooden window blocks in comparison with PVC structures.
Why in Europe do not like PVC
Polyvinyl chloride. Not very beautiful and a little frightening word, is it not true? So called incredibly popular today basic synthetic polymer. This material has a number of outstanding operational properties, therefore quickly found the application in almost all industries and especially in construction. His specific characteristics of PVC receives thanks to a certain set of all sorts of additives. Plasticizers facilitate the processing process of polyvinyl chloride, make it elastic, stabilizers prevent destruction in the production and operation of products, modifiers improve specific physical properties, fillers reduce the cost, dyes allow to produce colored products.
For more than 80 years, Polyvinyl chloride has become victorious of the planet, but its address constantly sounds regarding the safety of PVC products for humans. PVC manufacturers are fiercely fighting for their products, they are ready to prove its ecological purity with all their might. A certainty number of tests and tests has been carried out, a variety of certificates received. But completely safe supplements for polyvinyl chloride are not.
Recently, one famous manufacturer of plastic profiles announced that it stops to use extremely harmful lead and proceeds to calcium-zinc stabilizers.
And this is after almost a forty-year history of the manufacture of plastic with lead? After how many years now we will tell us the truth about calcium, cadmium, zinc? Russian consumer, financially able to afford high-quality euro-windows, is at the crossroads, it is well acquainted with terrible wooden products of the Soviet era, but something is alarming him in the windows of PVC. Many are not ready to fully and fully trust official sources and even more aggressive advertising statements of sellers of plastic windows.
Naturally, we are not trying to invent a bicycle, but we appeal to the experience of Western European states, especially since manufacturers of plastic windows in their booklets with pleasure lead relevant statistics. When they say that in Germany, the proportion of plastic structures is more than 50% of the installed window systems - true truth, but the percentage of this is the total mass of translucent structures. The windows of the residential premises on the homeland of PVC in 70% of cases are made of wood, and their share is consistently growing - by 3-4% per year, naturally due to plastic. If we talk about Scandinavia countries, there are generally more than 70% of all windows - wooden. The percentage of wood windows drops slightly in countries with small annual temperature drops and scarce forests, such as Spain, Italy, France. The reality is that, despite the global financial crisis, Europeans parquet, cotton and wooden joorear prefer linoleum, synthetics and plastic windows, and the PVC-windows market quickly and confidently shifts towards Eastern Europe.
What properties have wooden windows
The tree is pure, natural material that originally has excellent technological qualities: low thermal conductivity, good sound insulation, resistance to temperature effects, high strength. Unfortunately, wooden windows are afraid of moisture. Wood needs reliable multistage protection, including insects, microorganisms, fungi. Production of translucent wood designs is a high-tech, long-term, expensive.
Naturalness and beauty. Wooden windows are the embodiment of home heat and comfort, the aesthetic characteristics of wood products remain out of competition, despite fairly successful attempts to copy its texture. Qualitatively made wooden windows can become a highlight, the stem of the entire interior, largely define its style. Even convinced supporters of the windows from PVC, being adherents of the practicality and availability of plastics, will not argue with the exceptional attractiveness of natural material. Due to the ability to handle wood manually or using digital equipment, manufacturers of wooden windows can offer consumer products of a wide variety of non-standard forms. In turn, the desire for designers and developers to apply some "special" plastic window in the interior, simply impracticable due to the treason laconicity of angular PVC profiles.
Strength. Any breed of wood consists of fiber-oriented fibers, which, with a competent approach, alternating in a glued timber, their direction allows you to create very durable, durable, geometrically stable products. Compared to PVC windows, which will definitely stabilize the metal liner, they have an incommensurable smaller coefficient of temperature expansion. Currently, the window is most often made of pine, oak, larch, beech, cedar, fir, spruce, mahogany. Each type of wood has its own durability and durability. But do not forget that the more denser the material, the greater thermal conductivity it has.
Insulating properties. Wood has natural porosity, contains air in capillaries. Therefore, with an equal thickness of the profiles, the wooden window holds heat and extinguishes sound oscillations somewhat better than made from multi-chamber plastic. On average, 20-25% oak the warmer PVC, pine - by 25-30%.
The need for protection and periodic care. The stumbling block for wooden windows is atmospheric humidity. Wood can easily absorb moisture from the air, because of which the fibers will swell - the product leads. The rapid loss of moisture causes cracking and deformation with the subsequent loss of insulating characteristics. It is because of the fact that it is necessary to take serious protection measures, the total technological chain is so long, and the cost of wood products remains consistently high. Only multi-stage treatment of wooden profiles with antiseptic impregnation, soils and paintworks will provide windows practicality and durability. However, no matter how technologically, there was no coverage, it has its own service life, therefore once every 3-4 years, sometimes more often, you have to torn wooden window blocks, in particular the lower horizontal parts of the rods from the rain and ultraviolet. That is why the combined windows appeared, as well as options with aluminum or plastic overlays over the tree. In addition, with each year of operation, the protective coating loses about 0.01 mm thickness, which is why the wooden window should be periodically handled with special polyrols, varnishes.
Ecology. In fairness, we note that, despite the obvious safety of wooden windows, their production cannot be submitted without the use of a certain number of "chemistry". Powbanders, soils, shovels, paints, lesing compositions, antiseptic impregnations, adhesive for the manufacture of timber, butyl sealants of double-room windows - that's what manufacturers of windows from PVC say about the ecological safety of wooden window systems.
"Breathing" of wooden windows. Manufacturers of wooden windows declare that their windows "breathe". Some even suggest that through the micropores of wooden boxes there is an airbreaker such a volume that is able to provide ventilation of the room, which prevents condensate falling. They are little shy. Wooden windows sash have several sealing contours, wood is processed by the compositions that are filled in other words, such structures are almost sealed. The air entering the room through the window, for normal ventilation, it will be clearly not enough (GOST 24700-99 "Blocks of window wooden with double-glazed windows"), condensate will appear. That is why serious companies persistently offer their customers wooden windows with installed ventilation valves, which were originally invented for PVC products.
High price. With all the advantages of wooden windows, their price is quite high compared to plastic. For example, a standard window block from pine (1.45x1,8) already in the basic configuration "pulls" by $ 600-800, any other breed of wood will increase this price of an order. This largely explains why domestic consumers prefer to order plastic windows several times cheaper, which, besides, "do not paint", "this is not a tree - they will not crack, do not fail", "put," put a rag and forgotten. "
How do wooden windows
The material and design of the profile is the main thing that distinguishes wooden windows from PVC products. Production of high-quality window profile of wood The case is complex, long and very labor. It is not surprising that as soon as the first eurocon samples appeared in the post-Soviet space, the energetic owners of traditional "carpets" quickly surveiled their prospects and tried to establish the appropriate production, but did not achieve success. Even now many companies collecting wooden windows work with a purchased profile.
In most cases, modern wooden windows are made from a multilayer glued bar. It is not difficult that it has greater durability, better resistance to temperature drops, less hygroscopic compared to the ground-tree. Some manufacturers have mastered the production technology of high-quality windows from the array of northern pine, which is carefully selected and no less thoroughly dried. Raw materials intended for the production of timber is subject to several, quite complex preparation stages.
The first thing wood passes several stages of drying, the full cycle of which takes some time:
- natural drying,
- processing in the chamber - steaming and dry heating with alternating temperature indicators,
- normalization of temperature and achieving the balance of humidity.
Drying is designed to remove the internal stresses inside the wood, and also eliminate the possibility of cracking during the processing process. The preparation of the board in the drying chambers is automated, according to a given program for certain breeds of wood. The optimal humidity of raw materials at the outlet ranges in the range of 10-12%.
Next, wood is selected (optimized). Sections with knots, cracks, resin pockets, core residues, worms, sinks and stains are cut from the board. So the small planks are obtained - the define, on the ends of which the toothed spikes are formed. They are missing with water-repellent glue and under pressure spliced \u200b\u200bin one long board - lamella. The glued lamellas are kept in the press, after drying, they are plane (calibrated).
The next stage of profile production is the bonding of a timber of thickness. The boards are glued under the press, the plastics, while the inner layers are made of scrambled lamellae, and the outdoor mainly of the solid. As a rule, a three-layer timber is made, but some companies use technology with a large number of layers, and some lamellas can be pasted on the sides of a three-or four-layer pie.
It is very important that the fibers of the neighboring lamellae will be directed in opposite directions. Only such a glued bar is considered qualitative and able to ensure the stability of geometric forms of the product.
Then the wooden bar is milling on equipment with numeric software, resulting in a window profile with a very complex cross section. For the manufacture of windows with exclusive, non-standard forms, an individual approach may be required, "Handmade".
Next, the process of manufacturing a wooden window is significantly accelerated. A frame assembly occurs, which is polished, processed by impregnation (under pressure or vacuum), is ground, painted. After the end of the painting works, double-glazed windows and seals are installed, the fittings are mounted, the sash are hung.
Design wooden windows
Modern wooden windows are constructively similar to plastic products. For their operation, the same accessories is used, which allows producing not only swivel, but also a folding, swivel-folding opening of single sash. They also have several sealing contours. For glazing wooden windows, not only sheet glass is used, but also a variety of double-glazed windows, including special, energy-saving. The main difference between wooden windows is that they can have several design schemes depending on the number and type of sash. Note, some structures are historically connected with a certain country, which caused their "people's" classification on a national basis.
Single windows. This is the so-called European type, Euroko, the German window. In fact, it is a direct analogue of plastic windows, with the only difference that the profile is made of glued wooden bars. With a profile width of 68 and more than millimeters, a glass unit is installed in them from 36 to 44 mm. The design of the GRAYDA allows you to apply two or three seal contour for Eurocon, modern fittings makes it possible to manage all operations with the sash only with a handle. The accessories itself for such wooden windows produce the same firms that they work in the market of products from PVC: Roto, Maco, Siegenia-Aubi ... Naturally, the consumer becomes available such options such as winter slotted ventilation, stepped opening, trimming and other protection. Single wooden windows are currently the most common in our country.
The windows with separate sash are also called "Finnish". Such a window block is characterized by a large frame width, about 120-180 mm. On the external and inner side of the box are hanging independent sash, as on Soviet windows. A sheet glass is inserted into the outer flap, which serves as a peculiar buffer from the effects of various environmental factors, and the inner sash is supplied with a single-chamber, often energy-saving double-glazed windows. Interestingly, the outer glass seal is not hermetic, which prevents condensate on it - this is just the so-called "boot". Accessories, working in windows with separate sash, allows only a swivel opening, so the ventilation is carried out using the vehicle or the sash opening limiter. Thanks to a two-chamber design, such windows have excellent insulation characteristics, a significant width of the box prevents the impact freezing. Inside the Finnish window, there are sunscreen blinds, sometimes removable lattices.
The windows with paired sash are supplied to us mostly from Sweden. They also have a two-frame design. The main difference from the windows with separate sash lies is that the inner flaps of such window blocks are connected to the outer through the sliding connecting elements. The inner flap has a locking rotary-folding fitting, controlled by one handle. Therefore, many are also called "eurocams" with paired sash.
What kind of wooden window design is better, it is unambiguous to say difficult, each of them has its advantages and cons. For example, a two-chamber windows of a single window and glazing of two-dimensional windows (plus glass plus glass) have about some insulating characteristics. The wooden frame of two-dimensional windows is warmer due to a large width, but at the same time it is necessary to care for two, but for four planes; Separate design does not have a loved ones of the folding opening. Of course, the "Scandinavian" windows are more expensive than "European", but if you compare blocks with similar sound and thermal insulation, then the difference will not be very significant, especially when the first are made in Russia, and the second - abroad.
What should pay attention to, ordering wooden windows
Foreign manufacturers of wooden windows firmly entrenched in the Russian market. They are constantly working to improve the quality of wooden translucent structures, reduced their cost. Every year our attention is offered fresh design developments, new protective formulations and types of profiles. Western firms perform a full cycle of works from wood harvesting to the manufacture of double-glazed windows, they have large high-tech plants. Our manufacturers work on European technologies, on imported equipment, many of them profile and double-glazed windows are purchased on the side, often abroad.
Imported windows are about one and a half - two times more expensive than Russian.
From measurement until the moment of delivery, it will have to wait until three months, while domestic companies usually fulfill the order within 3-8 weeks.
Warranty is provided in most cases complex - on profile, double glazing, protective coating, accessories. Naturally, the window must be installed by the manufacturer. Russian firms usually give 3 years warranty, foreign - 5 years.
Windows made of oak about 2 times more expensive than from pine; Larch - 1.5 times.
Wooden window blocks made of timber with frenched outdoor lamellas will be cheaper on average by 15% than solid.
You can save, ordering a profile in which the outer layers are made of expensive wood, such as oak, and internal pine. There are options with a profile of a veneer of valuable breeds.
The window sizes are also somewhat cheaper than custom-made.
The longer the production time, the lower the cost of the window - so manufacturers regulate the flow of orders. But for urgency it will be necessary to pay up to 20%.
Blocks with twisted and separate sash 15-25% more expensive than single.
Often, the manufacturer of the windows can be ordered to be the corresponding rims on the color and texture of related products: window sills, slopes, platbands.
It is quite obvious that modern wooden windows and in our country will find their place, they will be more practical from year to year and more affordable. The plastic boom will end sooner or later, and the share of windows from the wood will begin to grow, especially since the Russian climate is sustained enough, while we have decent forest reserves, and by shoulders we have centuries-old traditions of wooden construction.
What windows are there?
What is it done from?
- Let's deal with what plastic windows are made: from the polymer and collecting chemical elements of the entire Mendeleev table in one bottle.
- And from what wooden windows? The wooden window block is a few dozen thin ecologically clean planes of the tree, purified from resin pockets and bitch, glued with special moisture-resistant glue impregnated with oil, lacquer, soil, which in turn also in its composition have a lot of chemical elements.
Technical Side
But to make the right choice of school, institute years and some logical thinking will help us. In the production of plastic windows, high-group safety polymers are used closer to class A (the profile class depends on the price and honesty of the performer). Also, all profiles from which plastic structures consist are special chambers and taps for micro-taking and dull moisture, a network of seals and a non-smaller network of silicone pistol.
"Budget" Wooden windows often have no cameras for moisture removal, do not have system channels for micro, but have the ability to absorb moisture, check out and swell during their improper manufacturer.

Video: Features and advantages of wooden windows
What about reliability?
Not quite familiar, our, who survived the Soviet times mentality plastic windows, of course, will not be able to replace ordinary wooden with vents, but from noise, dust and dampness to protect the dwelling in a state.
Wooden profiles with a double-glazed window, subject to quality manufacturers, can also be protected, but, alas, they will have to serve them every year, no matter how they spoke the manufacturers - a tree, it and in Africa, a tree and under any coating can either rot, or accumulate moisture and crack. And this is a fact known to everyone.
But still, as practice shows, for example, in Europe, plastic windows are installed in Europe, and the wooden there is installed there. And why? They are cheaper, the service is only in rubbing the profile rag, adjusting the accessories from time to time, and the replacement of seals after a number of years.
The tree with a good slack stand will be long, but not as long as plastic. Polymers lose their properties more than 300 years, and a tree? Air, moisture, sun and wind - and after 20 years the window in Truh (remember the old frames at grandmothers). Two packages either will not save the tree from moisture and erosion.
But with the competent approach of the manufacturer, with a high-quality primer of a bar in several layers, no less weak color and impregnating with antipirens and so on, the tree can also hold out for a long time, but the price will then be equal to the double cost of the plastic window.
