This article is about how to choose the right windows for your apartment. It just so happened that the window customer usually completely shifts the function of choosing windows to the seller. My task is to tell you what you should pay attention to when buying, and which factors are not of any importance. Let's get started.

Our goal is to acquire a warm, practical and durable window.

The points

  1. What window parameters do we have to choose?

There are several of them:

  • frame material. Currently, they are made from metal-plastic (PVC with metal inserts that increase the rigidity of the profile), wood (glued from lamellas and treated with protective compounds) and aluminum;
  • Position and number of opening and blind leaves;
  • Frame manufacturer and (in the case of metal and metal-plastic products) profile structure;
  • Manufacturer and design of window fittings;
  • Number of double-glazed chambers;

In this case, the chamber is called the air gap between the glasses in a sealed double-glazed window. The number of chambers is one less than the number of glazing threads: a double-glazed window made of two glasses is called single-chamber, with three - two-chamber, and so on.

  • In the case of special requirements for double-glazed windows - its functionality. It can be energy saving, sun protection and noise protection.

Material

  1. Which frame is better - plastic, wood or aluminum?

With a limited budget - plastic. Why? Here are the arguments in their favor:

  • Service life of less than 50 years;
  • No special care requirements. The surface of the PVC profile can be safely washed using any cleaning agents, including weak solutions of acids and alkalis. Only abrasive products are undesirable: their frequent use will make the glossy surface of the profile rough and make it get dirty faster;
  • The range of permissible operating temperatures is from -60 to +60 degrees, which allows them to be used in any regions of our wide and immense;

Plastic windows perform their functions in any climatic zone of the country - from the Crimea to Yakutia.

  • Possibility of painting in any color (including the entire volume of plastic) or pasting with a decorative film (including a textured one that very reliably imitates wood).

Why are competing solutions bad against this background?

Disadvantages of wooden frames:

  • High (at least one and a half more expensive than when using PVC) window price even when using cheap coniferous wood. The use of noble breeds increases it at least twice more;

  • To wash window frames, you can only use soapy water or special detergents;
  • The surface of the frames must be periodically (at least once a year) treated with a protective emulsion, compensating for the evaporation of the protective impregnation.

The choice of an aluminum profile means an unjustified increase in heat loss: aluminum is a metal with high thermal conductivity. Each frame will become a bridge of cold, contributing to the leakage of heat, and in extreme cold it will also be covered with frost (which, at the first thaw, will turn into water dripping onto the floor).

Warm aluminum profiles exist, but they are still the same combination of metal and plastic, only at a higher price than PVC frames.

sashes

  1. How to choose a window design - the position of deaf and opening sashes ?

I would formulate my experience with plastic windows of different designs as follows:

  • The blind sash at the top of the window is very inconvenient even with its considerable height: it is difficult to wash it from the outside. Much more practical opening sash in the entire height of the window opening. An exception is a window so high that the lock handle located in its middle will be at a height inaccessible to the owner;

  • It is highly undesirable to increase the width of the opening sash over 70 - 75 centimeters. It will begin to sag under its own weight;
  • A window with a width of more than 1.5 - 1.6 meters should be made tricuspid. In this case, the opening sash should be located in the middle, between two deaf ones. An alternative solution is two opening sashes along the edges of the opening.

This configuration of the sashes will again help wash the glass from the outside without the risk of falling out of the window.

Profiles

  1. Which plastic windows are better to choose according to the type of profile?

The main advice when choosing windows for cold regions is to look at the width of the profile. It can be equal to 60, 70 and 90 mm.

The greater the width, the less heat will be lost through the frames.

The most affordable are 60 mm profiles; on the other hand, in the 70 mm category, only high-quality products from eminent manufacturers are offered.

  1. What affects the number of air chambers inside the profile?

On the thermal conductivity of frames and sashes. More chambers means less heat loss. The mechanism for reducing losses is quite obvious: inter-chamber baffles limit air convection inside the frame, which transfers thermal energy between the outer walls of the profile.

  1. Who produces the highest quality plastic window profiles?

The Germans are Rehau, Veka and KBE. All these manufacturers have their own factories for the production of profiles in Russia, so they can offer a competitive price for their products.

However

Perhaps this statement looks seditious, but with the same width and number of air chambers, products from different manufacturers (including profiles of famous German companies and inexpensive products from Russian and Chinese brands) differ little in terms of performance.

The fact is that all products entering the domestic Russian market undergo mandatory certification. It eliminates the inconsistency of the profile with environmental requirements or low resistance to ultraviolet radiation.

German profiles have only one important difference from competing products - greater rigidity in relation to bending loads due to the greater thickness of the metal embedded part. However, stiffness is important mainly with a large window area and significant wind loads, and even then it is rather limited.

Let me give you my own glazing as an example. Two panoramic windows with an area of ​​13 square meters each are assembled on an inexpensive Chinese-made Hauteck profile. The glazing endures the strongest winter winds typical for seaside areas without any excesses.

accessories

Manufacturer

  1. What you need to know when choosing accessories? Which products are worth looking at? ?

Here, on the contrary, the manufacturer is very important: during the operation of windows, the fittings experience significant loads, therefore, the duration of the trouble-free operation of the window as a whole depends on the thoughtfulness of its design and the quality of the metal.

Here are four manufacturers that have earned themselves an impeccable reputation in this market sector:

  • Siegenia-Aubi;

  • Roto;
  • Maco;
  • Winkhaus.

As a rule, window sellers themselves offer to include fittings from one of the manufacturers I have listed in the window package. It is understandable: why do they need unnecessary problems with dissatisfied customers?

Functions

  1. How to choose fittings according to functionality ?

Here is what I consider to be a reasonable minimum feature set:

  • Blocker of erroneous actions. It does not allow you to turn the handle of the open sash, completely releasing its upper edge from the loop;
  • Transom mode (folding the sash towards itself). The hinged sash will allow you to ventilate the room in windy and rainy weather without flooding the window sill with rainwater;

  • Micro-ventilation mode - fixing the folded-back sash in intermediate positions. Installing hermetic plastic windows instead of wooden ones for an apartment means a violation of the well-thought-out ventilation system of rooms through the windows: it continues to work through the ventilation ducts, and the inflow completely stops.

As a result, an increase in humidity leads to the appearance of condensation on glass, frames and slopes, and after it - to black spots of fungus. Micro-ventilation provides a constant dosed supply of fresh air without the risk of cold drafts: the cold flow is mixed with the warm air rising from the heater under the window;

If the windows are already installed, micro-ventilation can provide installation on the frame and sash of the window retainer. This product costs 100 - 200 rubles; You can screw it to the window in 5-10 minutes.

  • With a significant width of the sash, a microlift is very useful - a simple device that raises its edge when closed;

  • The sash must be fixed not only with a central lock, but also with pressure rollers at the top and bottom. Otherwise, the top and bottom of the sash will inevitably move away from the frame, leaving gaps in the seal for cold air from the street;
  • In cold regions, another instruction for choosing fittings is important: its pressure rollers must have summer-winter modes. Turning the oval roller changes the sash pressure: in winter it is pressed more strongly, which compensates for the decrease in the linear dimensions of the profile during cooling, in summer it is weaker, which eliminates the deformation of the seal.

Turning the roller - eccentric allows you to adjust the sash clamp.

double glazing

Number of cameras

  1. Which plastic windows to choose according to the type of double-glazed window - single-chamber, two-chamber or three-chamber ?

It all depends on the climate zone.

In warm regions (Crimea, Kaliningrad, Volgograd and Krasnodar regions), single-chamber double-glazed windows are most in demand.

In areas with a temperate and moderately cold climate (the center of the country, the near Trans-Urals and most of the Far East), windows with double-glazed windows predominate in the assortment of sellers.

In the Far North (primarily in Yakutia and Chukotka), three-chamber (4 threads) glazing prevails.

energy saving

  1. What is energy-saving double-glazed window?

One of the glasses in its composition has a metallic coating (a multilayer coating based on silver and titanium oxides only a few molecules thick), which has limited transparency in the infrared spectrum. At the same time, glass transmits up to 90% of visible light.

What does it give?

In winter, when the temperature in the apartment is higher than outside, the coating reflects infrared rays towards the heated room, reducing heat loss. In the summer, energy-saving glass filters sunlight, filtering out the thermal part of the spectrum, and reduces the heating of rooms on the sunny side.

As a filling of an energy-saving double-glazed window, not air is often used, but an inert gas (most often inexpensive argon plays this role). Due to its lower thermal conductivity and higher viscosity compared to air, it further reduces heat loss due to convection.

It is useful for a potential buyer to know a few interesting facts, one way or another related to energy-saving double-glazed windows.

  • The market offers two types of energy-saving glass: hard-coated k-glass is obtained by applying a metal layer to a hot substrate, and i-glass with a soft layer is produced by the emission of metal molecules in a vacuum onto a cold surface. I-glass is more translucent with less permeability to infrared radiation, but its coating is very unstable in relation to mechanical stress;

On the left is an open balcony door, on the right is an energy-saving double-glazed window. As you can easily see, it almost does not darken the field of view.

This problem is solved extremely simply: even at the stage of assembling a double-glazed window, i-glass is mounted by spraying inside.

  • The sputtering of k-glass is strong enough to be used for single strand glazing;
  • A single-chamber energy-saving double-glazed window is a quarter warmer compared to a two-chamber package with plain glass and 40% warmer than a conventional single-chamber one. At the same time, the cost of a single-chamber energy-saving and two-chamber conventional packages are approximately equal, and the weight of the first of them is one and a half times less, which reduces the load on the profile and increases the service life of the fittings;
  • A double-glazed window, including two i-glasses, in terms of the quality of thermal insulation, approximately corresponds to a brickwork of 70 centimeters. At the same time, the second i-glass in the package increases its heat-insulating qualities by only 2-3%;

  • Argon in an energy-saving package increases its thermal efficiency by 8 - 12%, and in a regular one - by only 4;
  • During the year, due to the molecular diffusion of argon, up to 3% of its total volume is lost through the sealant;
  • It is impossible to determine the presence of argon in double-glazed windows by eye: you will have to rely entirely on the honesty of the seller. But I-glass is easy to recognize by looking at the reflection in the glass of the spark of a match or lighter: the metal coating shifts the reflected image to the red part of the spectrum;
  • Due to the lower penetration to IR rays, i-glass heats up five to seven degrees more than usual. Therefore, to reduce heat loss in winter, a double-glazed window should be installed with this glass inside, and to reduce the heating of the room in the summer months - outside.

In my attic (let me remind you - with a total window area of ​​​​26 m2 with a room area of ​​​​60 m2) single-chamber packages with one i-glass are installed. Climatic zone - Crimea, Sevastopol. The average January temperature is +3, the minimum winter temperature observed by me is -20C.

Two facts speak about the effectiveness of energy-saving glazing functions:

  • The flooring opposite the open balcony door, brightly lit by the sun, heats up several degrees more than the adjacent floor area, illuminated through the glazing;
  • At -20 on the street, 4.1 kilowatts of thermal power (28.47 watts per cubic meter) is enough to maintain comfortable +20 in the attic, which is noticeably less than the calculated value for heating systems of modern houses with insulated facades.

The photo clearly shows the thermal power of the inverter air conditioner - the only source of heat in the attic.

Light protection

  1. How is a light-protective double-glazed window arranged?

Partial permeability in the visible part of the spectrum is provided by a method already familiar to us - deposition of a metal coating with a thickness of a few nanometers. Glass can have a translucency in the range from 30 to 70% and have an arbitrary color - blue, green, gray, brown, and so on.

The main function of light protection is to reduce the insolation of the room on the south side of the house. However, in addition, the owner also receives protection from immodest looks from the street: the coating has a metallic sheen and, thanks to the mirror effect, does not allow the interior of the room to be seen from the outside as long as the street lighting is brighter than the internal one.

Light-shielding and energy-saving glass can be combined into one double-glazed window. This solution is popular in the south of the country.

Noise protection

  1. How to choose the right plastic windows facing a busy street ?

The main problem for you will be the noise from the street. The solution is a two- or three-chamber noise-protective double-glazed window. Noise protection is provided by two factors:

  • Different glass thicknesses (typically 4 and 6 mm);
  • Different widths of spacers that form air chambers between the panes.

It is also possible to combine any types of glass into a noise-protective double-glazed window - ordinary, light-protective and energy-saving.

Finish with a file after assembly

  1. What to do if you have already installed windows that do not suit you with their functionality?

Here is a list of typical problems with inexpensive windows that are installed by builders or offered by dealers in the lower price category:

  • Lack of tightness due to the lack of pressure rollers. It is treated by replacing a set of accessories. The replacement itself costs up to 1000 rubles per window. The cost of fittings is quite predictably determined by its manufacturer and functionality;

  • Lack of tightness due to deformation of the seal. It is eliminated by replacing the seal on the frame and the opening sash. The sealant is welded to the profile only in the corners and is usually easily removed from the groove with your own hands, and a blunt steel spatula can be used to install new insulation;

  • The absence of a micro-ventilation system is compensated by the installation of the window retainer or supply valve already mentioned by me;

There is an easier way to organize ventilation: just cut a couple of pieces of insulation 3-5 centimeters each on the frame and sash. On the frame, it is cut out from below, and on the sash from above: then all the dust from the street will not be transferred by the supply air to the living room, but will settle between the frames.

  • It is easy to turn a double-glazed window into an energy-saving or sun-protection unit by sticking a film with the appropriate functionality on the glass. Glass is washed clean and abundantly moistened with water with the addition of liquid soap or baby shampoo. Then the film with the liner removed, cut to fit the glass, is pressed against it and smoothed out from the center to the periphery with a rubber spatula or a plastic card.

A double-glazed window with a glued film will look neater if it is removed from the frame before the sticker. To dismantle it, it is enough to remove the glazing beads around the perimeter of the glass by prying them with a knife or a steel spatula. When installing, the glazing beads are pressed into the frame and are achieved with a rubber mallet.

How to choose high-quality plastic windows? This question interests everyone who is thinking about buying and installing them. At the moment, hundreds of organizations provide their services in this area, but it can be difficult to choose something suitable and of really high quality from the numerous options.

The main principles of choice

The current plastic windows are a complex system, which includes several elements. However, among them it is impossible to name those that are the main ones, and those that are secondary in purpose.

The main mistake of choosing people is focusing on a particular brand. It is clear that most advertised brands attract with their popularity, but they can greatly disappoint the buyer, since the appearance does not always reflect the content.

The first thing the buyer must decide is the purpose of the windows, the need for their purchase and installation. In addition, you should understand some of the nuances that relate to the device of this product. Technical parameters are completely dependent on operating conditions, therefore, when choosing windows, three factors should be taken into account.

The first factor is the temperature regime of the room in which the products will be installed. This also applies to the climatic conditions outside the building. Subsequent factors include the level of noise and the corresponding load, the requirements for safety. Therefore, such moments as the location of windows towards a quiet courtyard or a busy street, the floor on which the apartment is located, the room for which plastic windows are required, all this together is of considerable importance when choosing.

How to choose a profile?

The main element from which the profile for plastic windows is made is polyvinyl chloride (PVC). It is on the quality of this material that the service life of the entire structure, appearance and characteristics depend, since the profile is considered the basis of this product. You should choose only the product that has been certified, meets current quality standards.

When choosing a company, it should be taken into account that today's market is literally divided into different groups. You can find inexpensive brands or brands that occupy an intermediate position. Many Russian companies are engaged in the production of their own windows and may well compete with European manufacturers. However, they use raw materials and equipment from European countries.

Profiles from Western Europe make up a high price segment, their manufacture is carried out only outside of Russia. Most experts are convinced that there is no significant difference between the products of different companies, but they advise to beware of economy class products, that is, the lowest in cost.

In addition, they claim that the important indicator is the characteristics of the product, and not the brand and its popularity. It is on the characteristics that you should pay more attention.

The profile also performs a supporting function, which emphasizes its importance. Window statistics are affected by profile dimensions, length and width. For massive sashes and frames, a third sealing circuit, anti-burglary elements, a wide double-glazed window and a larger number of air chambers are designed. It is worth noting that the larger the profile width, the better it is, but purchasing such a product will be a costly affair.

The durability and strength of the profile is influenced by the thickness of the outer walls. If you follow the requirements of GOST, then middle-class windows should have a thickness of at least 3 mm. It is worth noting that there is a light version for economy class, in which the thickness is reduced to 2.5 mm.

For sound and heat insulation, air chambers play an important role, at the same time acting as stiffeners. A large number of chambers indicates that these qualities are at the proper level and the higher their number, the better the performance of sound and heat insulation. For unheated rooms and premises or for a temperate climate, three-chamber windows 58-60 mm wide are quite suitable. For most regions of Russia, it is recommended to purchase five-chamber windows with a width of 70 mm.

You should also pay attention to the reinforcing insert that will be used in production. It is used to give the necessary rigidity to the structure and stabilize the shape and linear dimensions, which can change under the influence of external factors, such as weather conditions. The insert is inserted into the main chamber of the profile. It is made of galvanized steel, the thickness of the sheet will be 1-2 mm.

Thus, when choosing a window profile, you need to pay attention to several points. The number of chambers, profile dimensions, including wall thickness, height and width, characteristics of the reinforcing insert and its presence deserve special attention.

The choice of double-glazed windows

The need for high-quality double-glazed windows is that it is a protection against extraneous noise and allows you to provide the necessary thermal insulation. In addition, double-glazed windows are multifunctional, and since they make up most of the window, their role increases significantly.

The main factors on which the choice of this element depends are represented by the level of noise exposure, climate characteristics, and safety requirements. These include such an aspect as the appearance of the product, but this is already at the choice of the buyer.

The choice of double-glazed windows is represented by a variety of designs, among which there are single-chamber and double-chamber, heat-saving and so-called safe double-glazed windows. In addition, there are also sun protection products.

The single-chamber design is represented by two glasses, between which there is free space. Depending on the thickness of the glasses and the dimensions of the distance frame, their thickness ranges from 24 to 26 mm. Such designs, which do not have technologies for saving heat, are suitable for warm climates and unheated rooms with good ventilation. Otherwise, they will often fog up.

A double-glazed window has high rates of sound and heat insulation. The total layer thickness is 32 mm, so they are well suited for central Russia. This type of double-glazed window is represented by a three-glass construction, which improves the performance of the window.

Glasses can be located at different distances, depending on the model and manufacturer. In different models, this distance can be 6 or 16 mm. This makes it possible to resist noise impact with different efficiency and improve thermal insulation properties. As for the insulation, some manufacturers resort to a technical trick, increasing the thickness of the outer glass from 4 to 5-6 mm. This step allows you to improve the insulation performance in the specified category.

New technologies in the manufacture of double-glazed windows

To reduce losses and heat or save it, energy-saving windows are used. There are designs with a soft or hard coating. The first option is represented by a film applied to the glass itself, and the second type involves the application of a heat-insulating material during the glass production stage. The material transmits light well, but reflects heat in the direction from which it is produced. That is, this technology will not lead to the loss of thermal energy.

In addition to the fact that heat losses are many times reduced, the room heats up less in sunny weather, which is good during hot weather. Another advantage of these windows is that condensation does not appear on the windows, and the material protects home items from the harmful effects of sunlight, leading to furniture burnout.

Another option for energy-saving technologies is filling the window chambers with gas. The gases used have a lower thermal conductivity and transfer heat more slowly than air. This leads to a decrease in heat transfer, as a result of which not only the cooling of the room is reduced, but also the cost of heating the room.

With regard to safety double-glazed windows, these windows have a polymer layer called triplex. Under external influences on the surface of the window glass, the fragments do not scatter in different directions, but remain in the specified layer, as a result of which the possibility of injury or injuring yourself is reduced many times.

Thus, the choice of a double-glazed window plays a big role, since not only the quality of the window, but also its characteristics depends on it. As in the case of the profile, you should not give preference only to famous brands, you need to familiarize yourself with all the parameters in detail. This also applies to new technologies used in the manufacture.

Let's talk about how to choose plastic windows correctly. In a modern apartment, all interior details should be carefully thought out, because they are a significant part of your life.

Therefore, the choice of such an important detail of the interior of your home as windows should be approached with particular care, paying attention not only to aesthetics, but also to reliability in operation. It is difficult to overestimate the importance of windows in a modern apartment, because it is through them that sunlight, air, as well as external sound sources enter the room.


How to choose good plastic windows

Let's take a closer look at modern metal-plastic windows and consider the advantages that make them so popular. One of the main advantages is soundproofing. Now the noise of the street will not prevent you from enjoying the comfort and coziness of your home nest.

Having installed metal-plastic windows in your house, you can be sure that even in a harsh winter the house will be warm, since such windows favorably differ in a high level of thermal insulation.

Reliability and durability are no less important characteristics of modern metal-plastic structures. Since the windows are not exposed to the summer sun, rains and frosts, in other words, they are not exposed to atmospheric influences, and as a result they do not warp, do not crack, their service life is up to 20 years.

Also, metal-plastic windows are unpretentious in care - you just need to remember to wash them with detergent from time to time. A wide range of shapes, colors, textures and design methods allows you to realize the most unusual design ideas, and simply give the room a cozy and elegant look.

How to choose the best windows, when choosing between plastic and wooden ones, take combined ones, because they contain all the advantages and eliminate the disadvantages of these two types.

We are convinced that metal-plastic windows are the ideal solution for a modern, warm and comfortable home. Now let's dive into the details. How to choose good plastic windows, the most common types of window designs are blind, tilt and turn.

Which window profile to choose

So, a blind window is a fixed, non-opening window. In operation, it is more reliable, since it does not have moving parts, but the room still needs to be ventilated, and therefore the combination of a blind window and a window that opens is popular.

Opening windows are divided into rotary and tilt-and-turn. A hinged window is a structure that opens with sashes inward, that is, traditionally.

A more complex design is a tilt-and-turn window, which opens both inwards, horizontally and vertically (the upper part of the window leans back). This design is more convenient, because you yourself choose how convenient it is to open the window at a particular moment. Which window profile to choose is up to you, of course, but the tilt-and-turn design is the most popular.

Depending on the size of the room, you can choose a single-leaf window (which consists of one window structure), a double-leaf window (it, respectively, consists of two window structures), and a three-leaf window. When installing windows, it is necessary, if possible, to avoid wide sashes, for the reason that they go far into the room and do not allow the use of areas of living space. In addition, the “heavy” sash creates an additional load on the fittings.

How many cameras should there be?

A very important point is the number of window cameras. The more chambers the window includes, the stronger and warmer it will be. Accordingly, if you want to protect yourself from the jokes of a harsh winter, it would be more profitable to choose a three-chamber double-glazed window, consisting of four glasses, between which three air chambers are formed.

The thickness of the glass is 4 mm, the space between the glasses is 10 mm. With simple calculations, we get the thickness of a three-chamber double-glazed window of 48 mm. If you are not afraid of frost, or in winter the climate pleases with mild weather, you can stop at a one- or two-chamber window. But residents of panel houses need to take note that double-glazed windows do not provide optimal thermal insulation.

The space between the glasses, except for air, is filled with inert gases or their mixtures to improve the heat and sound insulating characteristics of the double-glazed window. The most commonly used are argon and krypton, which are obtained by separation from liquefied atmospheric air.

When choosing a double-glazed window, it is important to remember that the thermal insulation of a window directly depends on the tightness, thickness of the glasses and the distance between them. And tightness, in turn, depends on the quality of the sealant.

Cheap designs use a short-lived silicone sealant that will cost twice as much to replace as its original cost.

What should be the glass

In modern windows, instead of ordinary glass, so-called low-emission (energy-saving) glass can be used, with a special coating with a layer of silver atoms.

Advice. You can check the intimacy of windows in a simple way: bring a lit lighter or match to the window. By the number of reflections of the light in the window, judge the number of cameras: if there are three reflections, then the window is two-chamber, and if four, it is three-chamber.

Also, using a match or a lighter, you can check for the presence of energy-saving glass - it does not cast a red, but a purple glow.

How long a new window will serve you depends on the thickness of the metal reinforcing profile that reinforces the PVC structure, which must be galvanized without fail, otherwise corrosion will begin to destroy it after a while.

Often, the cost of double-glazed windows is associated with the absence of galvanized iron. But, as the proverb says, we are not rich enough to buy cheap goods. When answering the question of how to choose the best windows, you need to remember that with savings, you can later spend more on replacement and repair.

accessories

A very important addition to the window design is fittings. Having spent money on windows, you should not save on bolts, handles, turning mechanisms, and other trifles, otherwise you will suffer from skewed sashes that constantly jam and stop. Additional expenses will not hit your wallet, but will pay off a hundredfold.

White is considered the traditional color of double-glazed windows, but if there is a desire, the color and texture can be ordered for every taste: both in a different color and “under the tree”. Additional accessories are also purchased: mosquito nets, window sills, safety glasses, etc.

No less important than the quality of the windows themselves is the installation process, on which the quality of their operation largely depends. Therefore, it will not be superfluous to personally control the installation of windows.

Manufacturer

When choosing windows, special attention should be paid to the manufacturer. To date, the most famous and reliable manufacturers on our market are Rehau, Salamander, VEKA and others.

Founded in 1948 in the Bavarian city of Rehau, Rehau was the first company to replace conventional materials with polymers. For more than half a century, Rehau has delighted customers with outstanding innovation and reliability.

The German company Salamander started producing profiles for PVC window and door manufacturers in 1973, and today the company is one of the leading European manufacturers of PVC profiles for window structures.

VEKA is also a German company, known in the CIS market for more than ten years. The company's products are distinguished by a wide choice of design forms and a variety of color shades. Of the advantages of the company's window structures, one can confidently name strength, tightness and good ventilation. But Veka windows do not always come out of the battle with fifty-degree frosts with honor.

I hope we answered your question, how to choose plastic windows correctly and not regret your decision. Choose worthy and enjoy the warmth and comfort of the hearth!
