Which is better to make plastic windows. Where to start the choice of metal-plastic windows? Types of sections of plastic windows

Metal plastic windows  Today they have gained unprecedented popularity, and there are a great many companies involved in their production. How to choose plastic windows, what to focus on when buying?

The advantages of plastic windows are not in doubt. They are much better than traditional wooden blocks. These designs do not allow dust, cold, moisture, do not require any complex care. High sound insulation - their main difference from wooden structures. But all these advantages are preserved provided that a quality product has been purchased. The market of plastic windows is simply oversaturated by various manufacturers. To attract as many new customers as possible, they offer various discounts and bonuses. And consumers in the pursuit of profit do not always pay attention to quality. More precisely, they simply do not know what to consider when buying a metal-plastic window in order to avoid big problems in the future.

Window construction

When choosing a metal-plastic window, you must pay attention to the following structural elements:

  • PVC profile;
  • glass;
  • plastic;
  • fittings;
  • type of ventilation.

It is also important to know how reliable the window manufacturer is and how better it is than others.

The life of the window depends on how well the installation rules for the window construction are observed.


Manufacturer

As for the brand, experts recommend choosing windows from well-known manufacturers (for example, German REHAU models installed more than 10 years ago have still not changed their quality and appearance): they care about their name and do not save on components of window models.

Today in Russia there are many factories engaged in the manufacture of domestic profiles. But often in the pursuit of savings, the quality of their products leaves much to be desired.


Profile

A window profile made of plastic is one of the main structural elements. He has a complex system. For products from a reliable manufacturer, the thickness of the external wall of the profile is 3 mm. Manufacturers who want to save money use thinner plastic, which will undoubtedly lead to a quick loss of the appearance of the window and affect the life of the window. The window will bend, change its parameters and ultimately can move away from the walls, and this will lead to the appearance of cracks and to all the consequences arising from this. But to visually determine which profile is in front of you is difficult.

The metal-plastic profile is reinforced with a reinforcing belt that will hold the window in case of temperature changes. Today, the climate is changing so often that it is impossible to predict what this or that season will be like. Therefore, it is better to purchase windows in which a galvanized steel insert with a thickness of at least 1.5 mm is present in all window elements. Thanks to her, the window will last much longer.

Unscrupulous manufacturers install black, unprotected metal, which is exposed to corrosion already at the very beginning of the operation of the window, or use thinner reinforcement.

The reliability and strength of the entire structure depends on the quality of the profile, so it is best to purchase windows made of certified material that meets the necessary standards and GOST.


Plastic

Most often, a low-quality profile is made matte. Unfortunately, it strongly absorbs dirt, and it is not always possible to wipe it off even with specialized means (which are also expensive).

The glossy surface of the profile is less susceptible to dirt. Even with the most inexpensive element, you can easily remove any stain. In addition, glossy plastic looks much better.


After a PVC profile, a double-glazed window is one of the important parts of a metal-plastic window. Its function is noise reduction and energy saving. Installation of a double-glazed window is carried out after installation of accessories. It is a block of 2-3 glasses, between which are sealed chambers. Glass thickness must be at least 4 mm. Unfortunately, you can “run into” 3 mm thick glass. But in this moment again you have to rely on the integrity of the manufacturer.

Double-glazed windows are of two types: single and double chamber. A distinctive feature of the latter is a high level of sound insulation. But they cost more. If you want to ensure a comfortable stay, especially if you live in a big city, do not save, choose two-chamber models. By the way, they have three glasses, not two, as many buyers think.

High-quality double-glazed windows from a reliable manufacturer have cameras of different thicknesses (this can be determined by the metal spacer inside the bag), the outer glasses should be thicker than the inner ones.

Check the number of glasses in the bag with a burning match, bring it to the window; you can’t check the thickness of the glasses, you have to trust the manufacturer, so again you need to choose the products of trusted brands.

Some manufacturers fill the glass with inert gas, which increases the thermal properties of the entire structure.

But here it is necessary to take into account one feature of two-chamber packages: they are quite heavy, and not every hardware is able to withstand the weight of the opening sash and not move. Therefore, special attention should be paid when choosing a window to her.

Glass with heat reflecting effect

Glasses with a special coating that allows reflecting infrared waves, that is, heat, are called energy-saving. Such constructions will not allow heat to leave in winter, and in summer they will not let heat into the room. They cost more than ordinary glasses, but provide housing with additional comfort.


Hardware

Thanks to the fittings (hinges, brackets, rods, connecting elements), the sashes are tightly attached to the frame, are in the right position, there are no gaps in the window structure. The whole mechanism is controlled with just one handle. The life of the window depends on the choice of fittings. Again, you need to choose accessories from reliable manufacturers.

Cheap parts on a double-glazed window design will significantly reduce window life. Problems will begin in six months: the sash will fall to one side, the fit will not be tight and even, cracks will appear.


Details

So that the air in the apartment is not stale and stuffy, it is better to choose windows with the possibility of folding the sash and adjusting the level of ventilation. It is possible to purchase designs with a micro-ventilation system and with special supply valves cut directly into the window box (they will have to make a hole in the frame). But not all manufacturers offer such parts, so information about them must be found out from the seller.

If it is important for you to constantly ventilate in an apartment or a house, then choose a system with heat recovery, it will provide heating of incoming cold flows due to the outgoing warm air masses.

Do not save on the installation of ebbs, mosquito nets. This will lead to greater costs in the future.

Drainages are necessary so that water does not fall into the gap between the wall and the window. The mounting foam, which was used when installing the window, will begin to collapse if moisture enters.

A mosquito net is a reliable protection of residents from insects, from which in the summer there is simply nowhere to go.

It is best to “dress” the entire window structure with high-quality plastic slopes. This will help prevent mold.

Do not choose drywall for finishing slopes, it will be covered with mold spots in the first winter.

Reliable manufacturers install white or transparent elastomer sealant on their products. Such a material is more expensive than a standard black seal, but it is resistant to temperature extremes and is more durable.

Before the winter season, grease the seal with a special compound or silicone oil.


The installation of a metal-plastic window must be carried out in accordance with GOST 30971-2002 “Seams of mounting units for adjoining window blocks to wall openings”. A properly installed design will last you more than a dozen years.

Find in your city a company that installs your windows in accordance with the specified GOST, it costs a little more, but it will be performed reliably and efficiently.

When choosing a metal-plastic window, you should understand that you are acquiring a thing that will be used by you for many years. Therefore, saving on trifles will significantly reduce its service life and add you trouble in the future.

It’s best not to focus on the brand, but to opt for a manufacturer that has established itself in the market for such products. And be sure to pay attention to the quality of components. This will subsequently avoid a lot of trouble.

No home or office can do without windows. Their types and forms are different, as well as the materials that are used for the production of window blocks. Wooden and metal-plastic, standard and arched, with increased protection against burglary and safe for children, colored and white, warm and with high light transmission - all this variety of windows is presented in stores. Recently, PVC windows have been especially popular, which is quite understandable by the excellent characteristics of these windows and the ease of care for them. However, the question of which metal-plastic windows are better still torments the consumer before replacing an existing window or when building a new house.

Modern window construction

In order to determine the choice of a window, you need to know the device of the window block itself. The components of the window are:

  • metal-plastic profile with structural elements (frame, impost, glazing bead, sash);
  • working fittings;
  • double-glazed window;
  • seals.

The stiffness of the entire metal-plastic window unit gives the frame of metal. In addition, the profile is equipped with channels for the removal of moisture and condensate, a sealant and a filter. Additional stiffeners are jumpers inside the metal-plastic profile. Thanks to these jumpers, a large number of compartments and chambers are formed inside, which are filled with air, which increases the thermal insulation characteristics of the window unit. In addition to the heat-insulating properties, the chambers also perform other functions: outflow of water, reinforcing stiffness, and fixing hardware.

Most often, the window unit is an immovable part of the structure (1 or more), imposts and sashes. The frame is mounted in the doorway. A leaf is a part of a window that is movable and rests on a vertical pillar (impost). The main part of a metal-plastic window is a double-glazed window.  The number of glasses in it starts from one onwards, is determined by the customer and limited by the manufacturer. Between these glasses is gas or air. The remote frame mounts the glass around the perimeter.

The sealant, which is most often silicone, determines the heat-insulating characteristics of the window. Seals are located on the edges of both sides of the glass packet, which serves as protection for the space between the frame and the sash. High-quality fittings (brackets, hinges, hooks, connecting elements) determine the characteristics of sound and noise insulation, service life. It is the fittings that take the maximum load over the entire life cycle.

Window companies

There are several significant manufacturers of metal-plastic windows on the market, which are often very difficult to choose from. Therefore, before finally deciding on the manufacturing company, the consumer proceeds to study all the big brands.

The consumer bases his choice on several factors:

  1. Company experience. Manufacturers who have been on the market for quite a long time are equipped with modern production facilities for making windows, and also have several qualified teams for their installation. After all, it is the correct installation of the window that will allow it to serve for a long time.
  2. Recommendations It is on the basis of existing experience in operating windows from a large list of companies that few remain that have proven themselves among the interviewed acquaintances.
  3. The professionalism of the staff.

A company whose experienced managers will help with the choice of the design of the future window unit, talk about its characteristics, causes more confidence among customers. In addition, qualified window openers, on whom the correct execution of a window depends, are also important for choosing a company. A company that has been working for the production of metal-plastic windows for a long time must certainly have crews for installing windows that possess all the necessary skills, have the appropriate certificates and tools. Delivery, guaranteeing the safety of the window unit during transportation, is most often carried out by specialists of the manufacturer.

Additional points

  1. Materials and applied technologies. A manufacturer who is confident in his products provides samples of all types of manufactured windows in sales offices. Moreover, these samples should be presented in section, enabling the customer to see the design of the window unit, as well as display the entire color scheme.
  2. Availability of warranty. Warranty Periods  services should not be overstated (15 years or more) and are at least 3 years. This warranty time is based on tests and is crucial for manufacturers. The warranty may include additional points to which this guarantee does not apply, for example, the low degree of sound insulation of the window installed in the house next to a busy road. The warranty can be supplemented by special customer requirements.
  3. Availability of packages of official certificates and permits. These documents must be required, and they can be on the various components of the window (double-glazed window, fittings). Their absence raises doubts about the quality of the metal-plastic window.

Only a high-quality plastic window can provide comfort in the house or a working atmosphere in the office. became the most popular among analogues.

This caused competition between manufacturers, and now there are many varieties of plastic windows on the market. In this regard, the problem of choice is ripe. Let's solve it together.

The quality and physical characteristics of the constituent elements of the window completely determine its reliability, functionality and durability.

Metal-plastic window construction:

  1. Frame is basic structure, which is attached to the window opening in the wall. It is made of a metal-plastic profile.
  2. A leaf is a movable part of a window attached to a frame. Sashes are also assembled from metal-plastic profiles.
  3. A double-glazed window is several glasses connected in a single tight design. Glass creates air chambers among themselves. There are single-chamber, two-chamber and three-chamber double-glazed windows.
  4. Glazing beads are plastic trims designed to fix double-glazed windows in a frame or sashes.
  5. Accessories are various window mechanisms: hinges, fastenings, locks, awnings, handles, etc.
  6. Seals are rubber cords installed at the joints between window elements: sash - frame, double-glazed window - sash, etc.

Which metal-plastic profile is better

A profile is a supporting frame of a window responsible for the strength and durability of the entire structure. Before making a choice, you need to study its design and basic technical characteristics.

The metal-plastic profile is a tandem of PVC and aluminum plastic. Inside, the profile is divided into chambers using plastic partitions. Each chamber has an individual purpose: reinforcement of the structure, condensate drain and mounting hardware. There are three, four, five and six-chamber profiles.

The cameras of the metal-plastic profile are filled with air. It is a poor conductor of heat, which improves general characteristics  window.

The main characteristic of the profile, in addition to strength, is its thermal conductivity (the less it is, the better). This indicator depends on several factors: width, number of sections and profile class.

The width of the profile and the number of cameras have a close directly proportional relationship - the more cameras, the greater the width of the profile. If you do not observe the proportions, then the effectiveness of a large number of cameras will be minimized.

The ratio of the width of the profile and the number of cameras:

  1. 58-70 mm is enough for a three-chamber profile.
  2. 70-90 mm is enough for four and five-chamber profile.
  3. 90 mm and more - for a six-chamber profile.

The metal-plastic profile is divided into classes - "A" and "B". More durable and resistant to operation in harsh conditions - a class “A” profile. A class “B” profile is a budget option, but its characteristics are sufficient for use in building windows.

How to choose a profile for a plastic window is described.

Which double-glazed window is better

A double-glazed window is a window element responsible for isolation from heat leakage to the street and from the penetration of street noise into the room. The efficiency of a double-glazed window is determined by several factors: the quantity, thickness and type of glass used.

The number of glasses in a double-glazed window affects its insulating properties, however, the principle "the more the better" does not work here. As with the profile, air chambers are created between the glass panes. Air is the main noise and heat insulator. Therefore, it is better to install a double glazing, but to increase the distance between the glasses than to install a narrow triple.

The thickness of the glass affects the characteristics of the window - the thicker the glass, the better the insulating properties. However, there is one important nuance - in a double-glazed window with glass of the same thickness, vibrations from street noise are created. These vibrations have a devastating effect on window construction and create additional noise. Getting rid of this phenomenon is very simple - you need to alternate the thickness of the glass in the glass. For example, the outer is 8 mm, followed by 4 mm, etc.

To improve insulation from noise and cold, the space between the glasses can be filled with inert gases, but this does not bring much efficiency, so if the budget is limited, you can refuse this function.

Types of glass used for double-glazed windows:

  1. Triplex is a glass coated with a special transparent film, which improves its soundproof and strength properties.
  2.   - This is a glass covered with silver atoms that reflect heat. It is installed on the inside of the room.
  3. Impact-resistant glass is coated with a transparent resin layer and is installed both on the outside and the inside of the room in accordance with individual preference.
  4. Tinted glass is coated with a transparent substance that absorbs light.

How to choose a window sash opening mechanism

One of the most important functions of a window is to air the room. There are many different ways to open the wings. Each of them is great for different situations and rooms.

Traditional window opening  carried out using a rotary mechanism. Usually these are awnings. The main disadvantage of turning tearing is the large swing of the sash, which requires free space.

Folding mechanism  provides a slight deviation of the sash from the frame at the top of the window. It is convenient for smooth ventilation of the room and does not require a place for opening.

Swivel mechanism  allows you to open the window in two ways - rotary and folding.


Bobbin opening  windows is used if two windows are installed on the window. At its core, these are two adjacent flaps that open with a rotary mechanism.

  - This is the newest and already popular method. The same principle of action applies to wardrobes. The main advantage of sliding windows is space saving.

Tilt-slide opening  windows are similar in principle to the sliding method, but its difference is that the window can be shifted to the side or opened in the traditional way.

How to choose plastic windows

The quality of metal-plastic windows directly depends on the quality and characteristics of the constituent elements. We have already figured out the main characteristics of the elements of the plastic window. Now the main task is to choose high-quality material. The only way to choose quality is to choose a brand.

The most famous brands of plastic windows:

  • Veka;
  • REHAU;
  • Salamander;

Additional requirements for choosing a reliable plastic window are accessories, seals and high-quality installation work:

  1. The fittings, together with the seals, should ensure a tight fit of the window sashes to the frame. If this condition is met, the design will be airtight, and therefore effective. It is important that the fittings have adjusting screws. They will allow you to configure the mechanisms, if over time the window loses its tightness.
  2. High-quality installation of a metal-plastic window consists in the correct installation, fixing and sealing of a plastic window. Only qualified and experienced specialists can handle this task, so the choice of an installation company must be done according to two criteria: work experience and good feedback from customers.

In order to calculate the cost of a metal-plastic window, it is best to ask for help from the company that will perform the installation. Then the information will be the most reliable, because the price will include all material and installation work.

The price of a plastic window varies from 3,000 to 15,000 rubles, depending on various factors:

  • profile quality;
  • hardware quality;
  • quality of a double-glazed window;
  • quality of sealing materials;
  • quality of installation work.

To summarize: the reliability of plastic windows depends on the quality of the constituent elements. And the quality of the constituent elements does not obey the rule “the more the better” - to achieve the greatest efficiency it is important to observe the proportions between quantity and size. It should also be borne in mind that not all the latest expensive technologies are more effective than the old ones. For example, filling the glass with inert gas does not pay back its costs.

If finally a decision was made to replace old windows with new metal-plastic windows, then the first task facing potential customers is the right choice of profile, that is, its manufacturer.

Below are tips for customers who are wondering how to choose plastic windows, placing an order for them:

  1. Find out which company is the manufacturer of windows, since you should pay attention to models from the manufacturer with a decent reputation in the window market.
  2. Before making a purchase, you should ask about the material from which the window is made.
  3. It should be ordered exclusively from authorized dealers, as no manufacturer in the world is engaged in direct sales, having an interest in:
  • the level of dealer prices did not differ from the prices of the manufacturer;
  • make normal discounts;
  • provide all relevant documents;
  • place an order accordingly after concluding a contract, issuing a check and a warranty card from a window manufacturer.

Before making a window purchase, a window opening is measured, for which roulette is used.She measures the width of the window on the outside. In this case, the window should be open. When measuring, the window box dimensions of the old window should not be taken into account. The mandatory presence of a mounting seam requires an additional 2.5 cm increase, since the seam will be covered with mounting foam.

How to choose the right windows made of metal

In the advertising of window companies, different types of PVC profiles are offered: from Turkish to German. A worthy choice should be made in a timely manner, protecting yourself from future regrets. The common winners in the global market for plastic windows are German companies.

The German profile has been produced for more than four decades at Austrian and German enterprises. The use of unique production technologies that have been tested by time with an appropriate quality control system for finished products has provided manufacturers with decent recognition in the market of metal-plastic constructions.

The very first thing that customers pay attention to is the type of profile used to manufacture this or that design. A profile can have not only domestic, but also foreign production. If it is made by a foreign company, then this is the most acceptable option, since domestic manufacturers often use recyclables for the manufacture of double-glazed windows having a low price when they are sold. Such windows suffer from a low level of quality, so you should promptly ask the seller if recyclables were used in the production process of the profile.

If the design of the glass packet is based on high German quality or it is made by another foreign manufacturer, which is no less in demand in the market of plastic windows, then the ability to withstand temperature changes in such a product is quite high.

The size of the reinforcing profile, which should exceed 1.5 mm, must withstand a certain dynamic load. You can immediately verify the normal profile size by contacting the administrator who implements plastic windows.

The best option is to use a reinforcing profile, the production of which used galvanized steel. There are two reasons for this:

  1. The best profile resistance to dynamic loads, for example, heavy wind.
  2. Excellent resistance to the negative effects of corrosion.

When choosing a profile, you must definitely find out the type of metal used in its manufacture. If ferrous metal was used, the structure will be subject to corrosion to the maximum extent, which will cause a quick process of rust.

What misconceptions arise when ordering windows, how to avoid them

One of the main misconceptions imposed by window companies is the following: the choice of fittings is not a fundamental point. This is often imposed by negligent manufacturers. The quality of the hardware purchased directly affects the properties of the product. The fittings are not only window handles, but complex structural elements on which the reliability of the product depends.

If you want to buy a wide window made of metal-plastic, then you should remove a little plaster on the slope to find out how many centimeters of the plaster layer it covers brickwork  or panel. To carry out all measurements, you can use the services of specialists from whom you can find out the basic nuances and subtleties when installing windows made of metal-plastic. It is best to immediately ask questions to specialists related to the design of the window, the location and installation of the windowsill.

In a double-glazed window the main role is played exclusively by its width and volume of glasses. Many companies are silent about such an important characteristic of products as the difference in the size of the distance between the glasses in the glass. An equal distance between the glasses does not complicate the manufacturing process, but creates a special resonance sound waves, which greatly exacerbates the noise protection of windows.

It is better to choose metal-plastic windows, the double-glazed windows of which have the correct distance between the glasses. You should think about the question of which glass to buy in order to place an order for the manufacture of a double-glazed window in advance. Everything will be determined by the characteristics of the room and the price level for glass.

It must be remembered that sound insulation and energy conservation depend on high-quality sealing material running along the perimeter of the window sashes, including fittings. Decent manufacturers often certify their products in accordance with standards. The company must provide a hygiene certificate, which confirms that the products of this company are harmless and certified for use without restrictions in housing.

What should be the profile for windows made of plastic

The profile is made of metal-plastic, including a profile (PVC), which is internally reinforced with metal.

The price and quality of the glass packet will depend on the type of material used. High-quality metal plastic should have a uniform color, if it is of poor quality, then it will collapse under the influence of sunlight, irretrievably losing its appearance.

Lack of reinforcement can lead to deformation, which will be accompanied by the formation of cracks and the absence of a snug fit of the wings. The window profile has not only special rigidity due to its reinforcement with metal inside the plastic, but also the presence of a certain number of chambers. The main thing is that the profile be fully reinforced, and not reinforced in some places due to reinforcement.

It is generally believed that the more cameras there are in a double-glazed window, the better the product retains heat. At the same time, the three-chamber and five-chamber profiles practically do not differ in their energy efficiency characteristics. In the room where the windows are made of metal-plastic, heat is best retained.

Products made from PVC profiles with chambers inside them have the corresponding thermal insulation properties, which is determined by the thickness and volume of the glass packet. The chambers are filled with dried air or argon. Gas only prevents fogging of the glasses, but at the same time increases the thermal insulation of the product. Given the weather conditions, it is possible to choose a single-chamber double-glazed window having energy-saving glass, or two-chamber with simple glasses.

What volume is better to choose a double-glazed camera

Manufacturers produce single-chamber, two-chamber and three-chamber double-glazed windows. Particular attention must be paid to such an element as a double-glazed window. It is necessary to determine in advance the required number of cameras in a double-glazed window. For example, a single chamber includes two glass and one air chamber. If the double-glazed window is three-chamber, then each of the cameras must be present in the frame and sash. Since it represents the basis of the window construction, a number of important requirements are presented to it:

  1. The number of chambers (air).
  2. Glass marking.
  3. Quality fittings.

For citizens of the Russian Federation, the choice of a double-glazed window consisting of two or more cameras will be suitable, since the temperature level in winter does not allow single-chamber packages. The thickness of the package should be 32 mm or more, which is ideal for Russian conditions. Domestic glass should have mainly the M1 brand. You can order imported glass, but at a greater cost.

Buying cheap brands of glass from little-known manufacturers guarantees only the use of low-quality window construction. High-quality glass is manufactured in Russia by the Bor Glass Factory. Such glass is able to withstand significant loads, while possessing heat-reflecting properties, which are achieved through the use of a special film. This innovation is one of the latest developments by manufacturers of window structures. When using it, minimization of heat loss by the entire window structure is ensured, but it is not necessary to use the film.

From metal plastic come in the most bizarre shapes: round and arched certainly you will not surprise anyone. Laminated windows are also not a novelty, and designer designs are made to order, and embody almost any client’s fantasies. But in addition to this, plastic windows have the most important characteristics, the knowledge of which will help to choose high-quality designs for your balcony.

Window Properties

A high-quality, good window should correspond to the declared characteristics.

Namely:

  • the lifetime of such a window is not less than 20 years;
  • high soundproof properties;
  • positive thermal insulation characteristics;
  • simplicity in leaving and operation.

Once again, you can emphasize - this should be absolutely any metal-plastic window, and its price does not matter.

A standard window unit includes two elements - a window frame and sashes, either opening or not moving. Separately, it is customary to highlight shtulp windows, they are distinguished by the engagement of the sashes with each other.

Types of sections of plastic windows

After thinking about which window will be convenient for your home, you have to choose and what type of section will be in the window.

Plastic windows can be with the following sections:

  • Hinged section. Activation of the “airing” mode or micro-ventilation is possible. This type is suitable for observation windows located at a considerable height, as well as roof windows.
  • Swivel section. The leaf in it can open inward, which entails a large influx of air. Outside, the sash opens in rare cases.



  • Swivel section. It combines both functions, which makes this type of section very popular.
  • Deaf section. The section cannot be opened, as it is completely adjacent to the frame, but, nevertheless, can be dismantled.

In different rooms and rooms, different windows are needed, so it cannot be said that there is some kind of universal type of section.

Features of the choice of metal-plastic windows

The most important thing in choosing is to take into account the features of the room where the window will be located.

  • Apartments, houses, offices require windows with two-chamber and three-chamber - they are warmer, more convenient, and in general, more perfect. Single-chamber windows are used for storage and various purposes of non-residential premises.
  • Reliable thermal insulation is the most important criterion for choosing a metal-plastic window if the building is located on the windy side.
  • Darkened metal-plastic windows are needed if the room is on the sunny side of the building, and other buildings are not obstructed by the house. Windows can be with a special film that has reflective pollination, or coated with a silver base.
  • If the building is located in the city center, or in an industrial area, they are not protected from dust. Therefore, a window with a mosquito net in this case is mandatory.





  • In the absence of natural ventilation, you need to choose a special profile. It is constructed in such a way that even with the shutters closed, a small air circulation is maintained. Otherwise, you will have to keep the ventilation mode all the time.
  • If the apartment is on the lower floors, the owners are not safe from the attacks of the “fortune-tellers”. So that they could not cause harm, you need to arm yourself with additional locking fittings, it is installed, as a rule, on the handles. A glazing bead is used to close the gap between the impost and the sash.
  • If the double-glazed window is intended for shops or office buildings, then the windows on the outside can be glued with a special film, shockproof. In some cases, armored glass is ordered.

These are just the basic selection criteria, which, in principle, are enough to not lose out with the acquisition.



The quality of plastic windows - what to look for

The seller can assure that the window is strong and warm, but you can verify this by looking at the design yourself. Thermal insulation and strength directly depend on the thickness of the walls, as well as the width of the cross section of the profile. Usually, as mentioned above, the average statistical conditions of our country suggest the choice of a three-chamber or two-chamber profile.

Narrow frames are also popular, but they make sense of installation only in those houses where there is external insulation. And, for example, in a panel house, this window will not be protection from the cold.

As for color, the most popular, of course, is white. But even if the seller cannot offer a profile of your preferred color, today many of them are pasted over with a special film or acrylic varnish. But the window will look better if the coloring pigment was added to the polyvinyl chloride during the manufacture of the profile.



How to choose a good seller

There are many companies offering window installation. And flyers look promising.

In order not to miscalculate, it is advisable to pay attention to the following points:

  • Require certificates for components and finished windows.
  • Check what the seller includes in the total cost of metal-plastic windows, whether there is window dismantling in this list. This is especially important when it comes to installing balcony windows.
  • The warranty period should be high enough.
  • Take the time to look at the showroom of the company that produces windows.

Nobody canceled the word of mouth, so listening to reviews is superfluous.

Today, metal-plastic double-glazed windows open up more and more possibilities - so, thanks to them, the balcony can be turned into a separate room. Be it a place with a berth and a lamp, where you can read and just relax. Or a minibar with a table for two and a beautiful view of the city. Or the balcony can turn into the workshop of the hostess, where she will store everything that helps to make the house cozy. The main thing is that it is the double-glazed windows that make it possible to realize such attractive prospects.

A good choice!
