What is better plastic windows or wooden euro windows. Wooden or plastic windows: which is better? Wooden windows are attractive
Probably, each of us, when building a house, or when replacing dilapidated frames in an apartment, faced the problem of choosing windows - plastic or wooden? Skewed and slitted, hard to close, dusty between the muddy openings of rattling glass, these construction elements from Soviet times have become the subject of numerous ridicule and an eyesore to caring owners of families.
Why plastic windows?
In many ways, it was the stereotype, formed from the past, that contributed to the boom in building know-how - plastic windows. More precisely, metal-plastic, because the frame is reinforced with metal from the inside for rigidity. Production of products began in the 1960s in Europe. At first there were imported from Germany and Poland. Then production was established in our country.
Plastic quickly conquered the window market in Russia, favorably standing out primarily for its insulating characteristics, tightness, durability, and aesthetics. As well as the absence of ever-jamming vents and bolts, as it is equipped with a convenient opening system in two (three) directions.
Competently and culturally built service marketing also played a big role in activating the demand for plastic windows. Manufacturers and suppliers of PVC windows immediately set up service and maintenance, offering the buyer the installation of products on a turnkey basis.
PVC - polyvinyl chloride - the main composition of the material.
It is enough to pay the purchase price - and there are no problems: delivery, replacement of old structures, installation, even cleaning and removal of construction debris.
Wooden windows could not boast of such attention to themselves.
Firstly, they were not included in the assortment at woodworking enterprises, therefore, they did not receive significant changes in production technologies laid down in the days of the USSR.
Secondly, manufacturing in the 90s was in the handicraft segment of the economy, and therefore there was a large percentage of defects. Moreover, it was difficult to legally punish such a manufacturer for dishonest work.
Thirdly, an inexperienced buyer had to both choose wooden frames and look for an installer - again, from the aforementioned "craftsmen".
And most importantly, the ease of use of PVC windows, their cleaning, in comparison with wooden ones, was undeniable.
Why wooden?
Few people know, but plastic windows in Europe have long lost ground to wooden ones. For example, today in the European market "wood" occupies 60%. It is not for nothing that the EU countries produce a huge amount of appropriate tools and lines for the manufacture of wooden windows.
Therefore, in the 90s, plastic window manufacturers, in order not to lose sales, began to develop the markets of the post-Soviet countries, offering seductive prices and service, the quality of which we mentioned above.
Gradually, thanks to thoughtful marketing and advertising, a stereotype was created for the inhabitants of the "scoop" that PVC windows are a symbol of prosperity and prestige. At the same time, in Germany, Austria, France or Switzerland, on the contrary, wooden euro-windows are a symbol of well-being and respectability, being aesthetically attractive and environmentally friendly.
But also more expensive, because the manufacturing technology cannot be compared with the Soviet "ancestors".
Previously, in the USSR, solid pine wooden beams were used for the manufacture of windows, which was economically beneficial, but caused deformation of window frames under the influence of humidity and temperature.
In Europe, a wooden blank is used from three- or four-layer glued beams. For production, pine (the inside of the beam), oak, ash, Siberian larch are selected, but there are production technologies from mahogany - meranti.
For example, light red meranti is similar in characteristics to oak, somewhat inferior in hardness.
The category of elite, and expensive, includes products made of beech and chestnut. There are almost none on the market, and not so much because of the high cost, but because of the complexity of preparing the source material and processing. For example, the manufacture of an oak window is preceded by a three-year drying of the blanks under certain conditions.
Manufacturers - especially small ones - replace the natural drying of wood with an electric dryer. This leads to the fact that the profile may be covered with black spots.
Note that a compromise in terms of the “price-quality” position is windows made of expensive wood on the outside and a layer of pine on the inside.
The blanks are processed and impregnated with chemical compounds that improve moisture resistance, protect against decay, but at the same time do not prevent the tree from “breathing”.
It is worth noting the variety of paint and varnish coatings for wooden windows. It is better to give preference to German, Finnish and Dutch paints, which preserve the properties of wood, improve the appearance of products, emphasize the structure of wood (if “under varnish”). Wide color and texture palette.
Differences between wooden and plastic windows: pros and cons
There are conflicting opinions both on hearing and on the Internet. But it is worth noting that most of them are initiated by interested parties, and therefore are subjective, speculative, and aim to “drown” a competitor or promote their product.
For an objective assessment of wooden and plastic windows, it is more correct to compare the advantages and disadvantages that have manifested themselves in the course of many years of operation. From the point of view of how these products have proven themselves in practice, common reviews and opinions are analyzed. So let's get started.
1. PVC windows are easy to operate
Because of this quality, they gained popularity in our country. But remember that plastic windows appeared in our country against the backdrop of a miserable state in the production of similar wood products. Modern wooden ones have an elegant appearance, and the profile is in no way inferior to plastic ones in terms of convenience. In addition, a partial repair of wooden windows is provided, the color can be easily refreshed or changed.
2. Plastic windows have excellent tightness
But, unfortunately, even too tight, and poor ventilation leads to mold and moisture condensation. This is one of the main disadvantages of metal-plastic products. To avoid this problem, you must either buy windows with a built-in ventilation system, or purchase a supply valve separately. Wooden ones are almost devoid of this drawback, because, as they say, they “breathe”. According to average data, a standard wooden frame passes about 2.5 cubic meters through its pores per day. air. Thus, wooden products contribute to maintaining the optimal air consistency, since wood stabilizes the humidity regime better than other materials.
3. PVC windows are highly thermally insulated
The question is moot. The air chambers of metal-plastic windows significantly reduce heat transfer. But the main merit in this is not so much profiles as double-glazed windows. And modern wooden frames are also equipped with high-quality one- or two-chamber packages (glasses connected along the contour, between which an air-filled space is formed). In addition, the wooden frame itself, due to its natural porous structure, has a lower thermal conductivity than PVC, which is especially important in Siberian cold weather or Asian heat. The same quality of wood prevents, unlike plastic, the appearance of condensation on the doors.
4. Plastic are highly soundproof
The claim is also debatable. As in the previous paragraph, it all depends on the quality of the double-glazed window and the number of glasses in it: the more, the more noise is delayed. But wood, due to its texture, is an excellent soundproofing material that is not inferior, or even superior, to plastic profiles.
5. Plastics are easy to care for and wash, even with abrasives.
It's right. Wooden products are more whimsical to the use of detergents, especially do not tolerate abrasive ones. Without proper care, they quickly age and become unusable. But on the other hand, unlike metal-plastic structures, wooden structures do not have electrostatic properties - they do not attract dust - therefore they do not need to be washed as often as plastic ones. This is especially important in industrial or arid steppe regions.
6. PVC windows tolerate high humidity without problems
This is true. Even more: plastic refers to hydrophobic substances (repel water). Unlike wooden competitors, plastic windows very well endure even prolonged contact with moisture or the influence of precipitation. Modern technologies are not yet able to completely protect wood from harmful moisture, which is the main cause of their decay and mold.
7. Metal-plastic windows tolerate temperature changes well, are frost-resistant
The claim is rather controversial. Frost resistance - this function is assigned exclusively to double-glazed windows. But very low or high temperatures (-40 - +40) are perceived differently by a wooden and plastic structure. Wood is a natural material, hardened under the mentioned temperature conditions, so it is physically more resistant. Due to its natural origin, wood, unlike all other materials, also has the lowest coefficient of expansion, which makes it ideal for use, for example, in very cold conditions. That is why wooden windows are especially popular in the Nordic countries - Finland and Sweden. PVC windows, especially considering the presence of metal parts in their structures, are quite vulnerable in this regard: a large temperature difference over time leads to a loss of insulating properties and, in general, structural strength.
8. PVC windows are less prone to deformation, more durable
A very controversial statement. It is still too early to draw conclusions about the durability of metal-plastic windows, since this product has been in operation for 20-30 years at the most. In fact, each of us has often seen old houses in which wooden frames have not changed for a hundred or more years. Even though they have peeling paint, the doors are already poorly fitted - but with appropriate repairs, they can last for more than one year. And these are windows made in those times when they did not even think about advanced technologies and materials used now. The only enemy of wooden windows is moisture, which leads to their deformation, infection with fungus and mold. But with proper care, this danger can be avoided. Plastic windows are subject to other misfortunes. The main one is a high coefficient of expansion with a temperature drop, which gradually leads to loosening, loss of strength. And not only in the plastic itself, but also in the places where it meets the window opening.
The fact is that wooden frames are made of homogeneous materials (the same in physical properties), which have a similar coefficient of expansion and perceive external influences in the same way. PVC windows in their design have different materials (especially metal fittings inside), and therefore they tolerate significant temperature changes worse than wooden ones.
Plastic without a metal base does not exist: polyvinyl chloride itself is a very fragile material, therefore, without proper reinforcement, the profile can be deformed. Another significant problem of metal-plastic windows is rubber seals. Even high-quality ones lose their properties over time, harden, begin to crumble, especially under the influence of low and high temperatures, detergents, exhaust gases from the street, etc. They are inexpensive, but replacing the entire profile is troublesome.
9. Plastic is dangerous for the environment
Polyvinyl chloride, from which window profiles are made, is extremely dangerous for humans. No less dangerous are various additives (plasticizers, dyes), which are released into the air in small quantities (especially when heated). It is this fact that is often cited as the main argument in favor of wooden windows. But not everything is so scary. Firstly, most of all toxic and toxic substances enter the atmosphere not from the finished window, but during the production of PVC raw materials.
Secondly, if we take into account the amount of plastic in the window and the volume of the room in which it is located, then the “harmfulness” from the emitted substances is reduced to virtually zero.
Thirdly, although there are harmful substances in the structure of the material, this does not mean that they must necessarily enter our body (unless, of course, we burn and inhale combustion products). In addition, we are already surrounded by a huge number of products containing plastic: linoleum, toys, vinyl wallpaper, various packaging, etc.
Yes, there is actually not a single thing around that would not contain some kind of poison. Another argument that is popular among opponents of plastic windows is that, unlike wooden ones, very toxic and poisonous substances are released when polyvinyl chloride ignites. In this case, there is only one advice: do not burn plastic windows in your apartment! It's a joke, but... But if, God forbid, it comes to a situation where the windows are already burning in the room, then these fumes are unlikely to be significant in the overall picture of the tragedy. As well as environmentally friendly burning of wooden windows.
A person's health is the most precious thing in the world, so such concepts as the harm or safety of a product have become one of the main tools in the struggle for the consumer between competitors. Not surprisingly, this area is most prone to subjectivism and bias. Sometimes a product that is hazardous to health is advertised as almost healing, and vice versa: a neutral product is presented as an environmental disaster.
10. Wooden windows are attractive.
Wood products have always been valued for their beautiful texture, aesthetic and attractive appearance. But there is no dispute about tastes. For example, metal-plastic structures are more suitable for a modern building "concrete-glass-aluminum" than wooden ones. In addition, PVC windows are now very diverse both in shape and color (about 50). Wooden ones are somewhat limited in the arbitrariness of structures (the radius of the arch is limited).
When starting a conversation about which windows to install, it is important to understand what we expect in the end result, depending on the functional purpose of the systems, our budgetary constraints and aesthetic preferences.
In the last 20 years, we have seen a trend when people began to massively abandon wooden windows, replacing them with plastic ones. Not even 10 years have passed, as the tree regains its lost positions, but already in a slightly different interpretation.
The main dilemma facing buyers is wooden or plastic windows, which is better. It is unlikely that a self-respecting specialist will undertake to answer unambiguously the question posed, but it is perhaps worthwhile to outline the main advantages and disadvantages of each of the options.
So, today there are 3 types of windows:
- from solid wood;
- from glued beams;
- metal-plastic.
Having understood the advantages and disadvantages of each of the options, we can make our choice based on individual capabilities and needs.
What you need to know about wooden windows
solid wood
The main material for such systems are: pine, ash, beech, oak, maple, hornbeam. These are most often hardwoods that are less susceptible to mechanical damage. If we order such a window for ourselves, and do not buy a ready-made one, we will have to wait for some time, since each element of the frame will be cut on saw machines and processed separately.
solid wood window
In order for the window to come out of high quality and serve its due date, it must be treated several times with special impregnations that prevent decay, infection by fungi, and insect damage. After that, staining, priming and varnishing only begin. Naturally, such windows will cost a pretty penny and take a lot of time.
Glued laminated timber
Windows made of glued laminated timber are essentially no different from analogues made of solid wood. A bar is thinly cut, glued planks (lamellas) obtained by sawing raw materials. The material differs in the number of lamellas per unit: three and five, on which its thickness depends.
Glued timber window
It takes a little less time to make such frames and the cost will be more democratic.
If we talk about the quality characteristics of wooden windows, then you should pay attention to their advantages and disadvantages.
Wood Benefits:
- the tree is an environmentally friendly product, safe for allergy sufferers and asthmatics;
- durable and strong;
- has a high rate of noise and heat insulation;
- provides natural air circulation;
- maintains a constant temperature;
- provides a normal level of humidity in the room;
- it's just beautiful.
Wood Disadvantages:
- change in size at different times of the year;
- high price;
- the complexity of manufacturing;
- duration of production;
- combustibility of the material;
- difficulty in care (compared to plastic windows, but more on that later).
So, wooden windows, no matter which option we choose, solid wood or glued laminated timber, it is beautiful, practical, and environmentally friendly. The main thing is to decide on the type of wood and order the manufacture of a good carpenter who will do his job with high quality.
Plastic windows
Plastic windows are also known to us as PVC (polyvinyl chloride). This is a relatively new material used for the production of plastic structures and stretch ceilings. Today, PVC technology has strict quality standards and sanitary and hygienic regulations that control and prohibit the presence of heavy metals in the alloy, thus protecting consumers from toxic and chemical fumes that are harmful to health.
Plastic window
Since the 80s of the last century, a ban was introduced on the use of lead and zinc in the manufacture of a polymer profile; they were replaced by less toxic chlorine, whose vapors begin to be released at a temperature of + 270 ° C and above.
Advantages:
- durability;
- complete sealing of the room;
- ease of construction;
- no restrictions on the form;
- ease of care;
- complete noise and sound insulation;
- possibility of installation of the top rotary mechanism;
- protection against the entry of insects into the room.
Flaws:
- the possibility of the appearance and reproduction of mold;
- lack of natural air circulation;
- formation of condensate due to violation of convection;
- inability to correct mechanical damage.
What is the result? Plastic windows are a modern version of the wooden counterpart. They are easy to operate, quick to manufacture and suitable for all sizes and design features. They can have protection against children, anti-burglary system, do not burn and do not change their size depending on weather conditions.
Safe Windows
When choosing which windows are better, wooden or plastic, manufacturers' feedback on the safety of the system is no less important for consumers.
Safe Windows
We have already figured out the material from which windows are made, now it remains to understand what safe windows are. 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 double-glazed window and fittings.
A double-glazed window is not a set of glasses in a frame, it is an airtight space filled with gas, which performs the function of heat and sound insulation, prevents heat from escaping into the street, which is especially important during the heating season.
Choosing what will be the main material of the window, wood or plastic, you can stop at the combined option, when a double-glazed window is inserted into the wooden frame, in this case both the disadvantages and the advantages of the systems merge together. We get an environmentally friendly product, maintain natural ventilation in the room, protecting ourselves from street sounds and reducing heat loss during the heating season.
From the moment of its appearance on the market, plastic windows have become the undisputed leader in sales, and consumers have not puzzled themselves with the question of choice for a long time. They ordered this modification without hesitation. This dominance of PVC profile structures continued until the technology for the production of wooden windows made it possible to significantly improve their performance and reduce costs. From that moment on, many buyers began to doubt which windows are better - wooden or plastic?
Surprisingly, but in this matter there are no unambiguous criteria for selection. Both options are good in their own way. Wooden profile products outperform PVC windows in some ways, but they are inferior according to some criteria. The final decision is made based on the allocated budget, features of operation and personal preferences.
Structural differences between plastic and wooden windows
Wooden and plastic windows differ not only in the material for making the binding. When assembling them, different technologies and opening mechanisms are used.|

When considering these parameters, plastic windows are superior to wooden ones only in terms of fixation, as well as sealing of double-glazed windows and glazing beads. Such a difference is felt not during operation, but during the dismantling of these elements. Beads and double-glazed windows from wooden models are much more difficult and longer to extract than from plastic ones. This nuance must be taken into account when ordering windows, since double-glazed windows have to be changed for various reasons. In addition to the problems with removing stuck double-glazed windows and removing old silicone, you need to keep in mind the need to restore glazing beads, the surface of which can be damaged during the work.
Plastic and wooden windows - which is better?
To find out which is better wooden or plastic windows, you need to compare performance characteristics. A comprehensive study of the main parameters will help to make a choice in favor of one or another material.|

**As an example, the minimum cost of pine windows is given. If larch, oak, ash or mahogany is used for the manufacture of structures, the price difference will increase.
***Since the European beam is mainly used in the manufacture of windows, it is necessary to take into account the frost resistance not of the material itself, but of the adhesive joints. Usually this indicator varies from -40 to -50 ° C, and it is enough for our climatic conditions with a margin.
As can be seen from the table, wooden windows are superior to plastic ones in some respects and inferior in others. Wood structures are more durable, retain heat better and absorb noise. But plastic windows are more resistant to atmospheric phenomena and have an affordable cost. When comparing the heat and sound insulation of structures, it should be borne in mind that the maximum indicators are observed at, read more about them in a detailed review on WindowTrade.
Some sellers of wooden windows still claim that their products, unlike plastic ones, breathe. This is not true, because after treating the wood surface with primers and paints and varnishes, the pores are clogged. In terms of airtightness, timber models do not differ from PVC windows.
Which plastic windows are better
It is possible to compare plastic windows from different profile systems only if they are equipped with the same double-glazed windows and fittings. In this case, the characteristics of sashes and frames are considered. Subsequently, this analysis and consultation of managers will help to find out which plastic windows are best placed in different situations. The quality of polyvinyl chloride, from which profiles are made by reputable manufacturers, is approximately the same today. As a result, products must be evaluated according to the following criteria:- outer wall thickness (2.2-3mm) - ideally, you need to strive for a larger value;
- number of internal chambers (from 3 to 9)- in our climatic conditions, it is recommended to use systems with at least 5 cameras to equip heated residential premises;
- installation depth (58-150 mm)- the larger this parameter, the better;
- rebate depth for double glazing- it is desirable that this size be at least 20 mm, but 23-25 mm is considered the optimal value;
- the maximum possible thickness of installed double-glazed windows (30-56 mm)- thick double-glazed windows retain heat better and dampen sound waves, therefore, in this case, you need to strive for the maximum value.
Pros and cons of plastic windows
To assess the attractiveness of this type of product, you need to translate all technical specifications into a language understandable to the buyer. This is best done by listing their advantages:- Durability- thanks to special plasticizers and additives, PVC profiles, with proper care, do not change their shape, color and dimensions during the period declared by the manufacturers.
- Minimum care- plastic windows are easy to maintain in working and aesthetically attractive condition. It is enough to clean and lubricate fittings with sealing contours in time, as well as periodically wash the surface of profiles and double-glazed windows.
- tightness- constructions made of PVC profiles do not allow air, water, dust and noise to pass in both directions.
- energy efficiency- with the right selection of the type of profile and double-glazed windows, plastic windows do not allow the slopes to freeze through and retain heat well in the interior.
- Versatility– these models can be adapted to any interior design. The exception is the elite furnishings in a classic style.
Since the advantages of PVC profiles are much greater than the disadvantages, they are readily purchased for installation in residential, municipal, commercial, sports and industrial facilities. These unpretentious structures can be used wherever they are in harmony with facades and interiors.
Which wooden windows are better
Although approximately the same methods are used for the manufacture of wooden windows today, the operational and aesthetic characteristics of different modifications differ significantly. They depend on several factors:- wood species- larch, pine, ash, oak, meranti and mahogany, which are used today for the assembly of doors and frames, have different properties;
- window type- there are single- and double-leaf, vertically sliding and sliding models, and their thermal characteristics largely depend on the design of the binding;
- type of paintwork- the quality of the wood surface finish determines the appearance of the windows and the durability of the protective and decorative coating;
- type of timber– Parts for assembling windows can be made from solid or spliced solid wood.
Advantages and disadvantages of wooden windows
Modern wooden windows have almost the same advantages as plastic ones - tightness, energy efficiency, durability and functionality. In addition, these products have the advantages of an individual character:- fire resistance- a wooden beam impregnated with a special composition is charred during thermal exposure, and does not melt like a PVC profile. This gives more time to leave the premises through the windows during a fire.
- Pleasant tactile sensations– touching natural wood cannot be confused with anything else.
- Rich selection of decors– despite the limited number of species used for the production of wooden windows, surface finishing technologies have expanded the design possibilities of manufacturers. Through the use of various techniques, stains and paint mixtures, any window texture can be created.
- Respectable appearance- even products from inexpensive breeds ennoble the interior of the interior and make it more solid. In terms of aesthetics, neither plastic nor aluminum structures can compete with high-quality wooden models.
- Possibility of manufacturing structures with large active doors- according to GOST, an increase in the base section of a beam allows for a 10% increase in the maximum allowable dimensions of products.
It is advisable to install wooden windows in cases where the use of plastic structures will negatively affect the interior or exterior of the facade. In addition, such products should be used, if necessary, to minimize the processes of heat transfer between the walls and the frame. However, in any case, it is desirable that there is free access to the outside of the structure. This will allow you to regularly care for the surface of the tree and keep its aesthetic appeal longer.
What windows are better to put in an apartment
To figure out which windows are better to put in an apartment, it is recommended to consider the possibility of caring for their outside. Wooden windows will sooner or later require restoration of the frame and sashes from the side of the street. On the upper floors, this procedure is quite difficult to perform even with the involvement of craftsmen for high-altitude work with special equipment. The paint layer must be applied in sealed chambers, and it is impossible to create such conditions from the outside of a multi-storey building.In addition, high-rise buildings are usually located in the most polluted areas of the city. An unfavorable environment quickly destroys the paintwork and the wood itself. PVC is more resistant to such conditions. As a result, plastic windows for apartments are the best option. If the interior design requires the use of wooden frames and sashes, profile lamination can be performed. You can imitate the surface of natural wood only on one or both sides of the frames and sashes.
When installing wooden windows, you must immediately take into account the problems that you will encounter during their restoration. To perform a high-quality replacement of the paint layer, it is often necessary to dismantle the structure, and on the upper floors it is almost impossible.
Which windows are better for a wooden house
For installation in houses made of logs or timber, it is better to give preference to wooden windows. There are several reasons for this:- Laminated PVC profile retains a rich color for decades, while natural wood gradually fades. In a few years, wood-like plastic windows will stand out strongly against the background of the facade plane of a house made of timber or logs.
- The proximity of natural and artificial materials often harms the interior and negatively affects the overall environment.
- Wooden windows are much better combined with decorative platbands, which are used to decorate openings.
Regardless of the type of windows, they must be installed in wooden houses using a special technology that will eliminate distortions. This technique ensures the mobility of the frames relative to the walls, so that the binding structures do not deform even with significant subsidence.
