During the repair, we must not forget about the "mirrors of the soul" of our home - the windows. When choosing between wooden or PVC structures, few people today prefer wooden windows that are expensive and troublesome to maintain and install. Plastic structures are a modern answer to the last century. But they are also divided into types and categories that differ from each other in many ways. Let's find out which windows are better to put in an apartment and how not to get confused in their diversity.

Components of a window structure

Before replacing old windows with plastic ones, it is necessary to study their main components: correctly selected elements ensure the reliability of the entire structure. The metal-plastic window consists of:

• profile;
• double-glazed window;
• accessories.

Each of these elements is divided into different types and is selected depending on future operating conditions.

What is a profile?

Profile - the supporting base of the PVC window, on which the double-glazed window is held. The profile includes three elements:

• frame;
• glazing bead;
• sash.

Frame

A frame is a blind element that is mounted in a window opening. When choosing a window, you need to pay attention to the material from which the frame is made:

• Matte plastic is an impractical material that is becoming rarer. Its main disadvantage is that it quickly gets dirty, and traces of dirt and fingerprints remaining on the frame are difficult to clean.
• Glossy plastic - outperforms matte plastic in every parameter. Of course, on the gloss, all traces and prints will stand out more, but it is also much easier to wash them - just wipe the surface with a damp cloth.

Bead

The glazing bead is a narrow bar with a thin rubber gasket that holds the camera. Its width depends on the thickness of the double-glazed window, the shape can be different - figured, rounded, square. They are made of two materials: PVC or glass composite, which is characterized by increased strength and higher cost.

Tip: the glazing bead has a limited service life, after which it needs to be replaced, so you should pay attention to the glass-composite product.

Additional functions of the glazing bead:

1. Preventing drafts and dust from entering the gaps between the frames.
2. Noise and heat insulation.
3. Giving the appearance of the window more aesthetics and completeness.

sash

To choose the right type of PVC window sash, you need to consider its types separately. She may be:

• deaf;
• rotary;
• folding;
• swing-out;
• shtulpovy.

It is a fixed PVC window structure, it cannot be opened. The advantage of such an element is its cheapness (due to the lack of fittings and panels), the minus is its immobility. It is permissible to install a blind sash only in combination with an opening one, otherwise it will not be possible to ventilate the room and wash the double-glazed window from the outside (if this is not the first floor of the house).

A blank window has a symbolic designation with the signs "+" or "×".

swing sash

This type of sash is much more convenient than a deaf one, but it is better suited for a window opening that has a large height and small width. The overall swing product creates some inconvenience in the form of a strong draft. Also, indoor flowers cannot be placed on the windowsill of such a window.

The hinged sash is symbolized by the mathematical sign "<».

Hinged (fanlight) sash

This type of sash in PVC windows can be tilted at the top by a certain degree. This option is usually installed in small rooms where it is necessary to economically use the size of the room and regularly ventilate.

Tilt and turn sash

It has the best reviews in terms of convenience and functionality of the design. It is a little more expensive compared to the previous options, but the window is not set for a year or two, so it is worth considering in advance the options for using the space around the window. The tilt and turn design is a sash that, depending on the position of the handle, swings horizontally inwards or leans upwards.

Classification of PVC profiles

Window profiles differ in the following parameters:

• wall thickness;
• by the number of cameras;
• by type or class.

The dimensions of the profile are selected depending on the thickness of the walls and the dimensions of the opening. A properly selected profile provides better insulation and sound insulation of the room.

Number of cameras

If you look at the profile in section, you will clearly see that its internal space is divided into isolated chambers. In the middle there is a reinforcing metal U-shaped insert, other profile chambers are designed to drain condensate and create an additional air cushion to improve the heat-saving properties of the window.

The number of air chambers of a metal-plastic profile varies from 1 to 8 and directly affects its energy-saving properties. For central Russia, a profile with 2–5 cameras is suitable.

Thickness of outer and inner walls

According to this parameter, profiles are divided into 3 types:

1. A class - the thickness of the outer wall is at least 2.8 mm, the thickness of the inner wall is at least 2.5 mm.
2. B class - at least 2.5 mm for the outer and 2 mm for the inner walls.
3. C class - does not have clear requirements for the ratio of wall thickness.

Profile types

Profiles for PVC windows can be divided into three types:

1. The economy option is the cheapest type. The standard size is 58–62 mm. With such a profile, a single-chamber double-glazed window with a width of 24 mm is usually installed. Withstands temperatures down to -15°C and does not let in drafts.
2. The standard is a generic type. The standard size is 62–74 mm. Three- and four-chamber profiles can be installed with a double-glazed window with a width of 38–42 mm.
3. Suite - the most expensive and high-quality view. The standard size is 90 mm, but the range of sizes starts from 80 mm. It is a five-chamber profile with a double-glazed window 38–42 mm wide. Compared with other types, it has the best heat-saving capacity and has a more attractive design.

Manufacturer rating

• Rehau;
• Veka;
• salamander;
• Mont Blanc;
• Kaleva.

Types of double-glazed windows

A double-glazed window is the second most important element of a PVC window. The heat and sound insulation properties of the structure depend on it. They can have from one to three air chambers. In addition to dividing on this basis, the following types of double-glazed windows are distinguished:

1. Frost-resistant - the fogging process does not begin at -35, but at -55 degrees. They are used in regions with a harsh climate.
2. Sunscreen - reflects ultraviolet rays.
3. Shock-resistant - Triplex system bags with a special film coating are able to withstand even strong impacts. It is expedient to put them to the inhabitants of the first floors.
4. Energy-saving - due to special reflective i-glass with sputtering and the presence of argon in the chambers, they retain up to 90% of heat.
5. Noise-proof - they have chambers of different thicknesses, they may additionally contain resin as an insulating layer.

Single-chamber double-glazed window

It consists of two glasses, between which there is an air layer that provides heat and sound insulation. Metal-plastic windows with a single-chamber double-glazed window are best placed in regions with a warm climate and when living in areas with a low noise figure, since they are not able to provide a high level of heat and sound insulation. In addition, the owners of apartments with installed single-chamber double-glazed windows complain about constantly “sweating” windows.

Double glazing

It consists of three glasses, between which there are two air cushions. Compared to the single-chamber version, this one has much more attractive characteristics.

By varying the thickness of the glass and the dimensions of the chambers in the double-glazed window, making one of them wider, you can significantly reduce heat loss and noise levels in the apartment. For a product with a thickness of 32 mm, the ratio of the thickness of glasses and air chambers will look like this:

• standard version - 4 × 10 × 4 × 10 × 4 - three glasses 4 mm thick with two chambers between them 10 mm each.
• improved - 4 × 12 × 4 × 8 × 4 - the camera, located closer to the street, has a greater thickness.

Three-chamber double-glazed window

Due to the presence of three glasses and four air chambers, it perfectly retains heat in the room and does not let in street noise. It is not popular because of the large thickness, which is not compatible with every opening, and the massive weight, which leads to rapid wear of the fittings. For effective protection against severe cold or for high-quality sound insulation in the city, it is better to prefer energy-saving and noise-protective options.

accessories

Fittings are all movable metal or plastic window elements: handles, hinges, locks, counter parts of locks, various covers for hinges, etc. These are small in size, but by no means small in importance details that should not be saved on. These elements will be used every day, which means they must be reliable and of high quality.

The decision was made to install a plastic window. Types of windows - what are they? The best ones are the ones that suit your home.

First stage

First you need to choose the form how the window will be located, view the types of windows, and only then make a decision. They should be chosen in proportion to the room: there should be enough light in the room, but if the opening is too large, the feeling of comfort is lost. is a necessary element that is tightly connected to a brick or other wall. The sashes in the product are a movable part, which, depending on which fittings are used, can be folded or opened in different ways. There are sashes that, when opened, rotate around their axis vertically or horizontally. Fasten the double-glazed window with the help of glazing beads in them.

Plastic window: types of windows by frames and sashes

They are one-, two- or three-leaf, differ in the number of chambers in the double-glazed window. In terms of their functionality, such models are close to ordinary wooden windows. These options are ideal for those people who prefer to install inexpensive, but quite practical products in their home. A traditional window will do here. These types of windows are ordinary rectangular structures that open inward. A small minus that is inherent in standard plastic double-glazed windows with rotary shutters is that ventilation in winter is quite problematic, since cold air enters with a fairly strong flow when the window is open.

Deaf types of plastic windows are good for everyone: durable, reliable, plus inexpensive. These are windows with fixed, locked sashes. In addition to these elements in the product, the frame itself can hold the glass. The disadvantage of such window boxes is the impossibility of opening. This model is recommended to be installed with a decorative purpose: it will add space and light to the room. A blank design is quite acceptable in a space that is equipped with sufficient ventilation: in cafes, restaurants, gyms and other similar establishments.

And finally, tilt-and-turn windows - the types of windows of this design are the most popular and in demand. In the summer heat, the sash can be easily opened completely, and in cold weather, it is enough to open the upper part of the window for ventilation in a horizontal position. It is very convenient to use this function in inclement weather, especially if the layout of the apartment contributes to the formation of drafts. The folding position eliminates the possibility of their occurrence and helps to avoid the risk of damage to the structure if the window suddenly slams shut.

Swivel plastic windows can be opened only in one direction, which is not always convenient. Hinged products can only be opened from the top, so they are great for stairwells, basements, and other spaces where casement windows can be a hazard, not just a nuisance. They rightfully got a leading position due to the fact that they can turn and recline.

Profiles

Today, manufacturers of plastic products offer a fairly extensive range of PVC window profiles, from which a plastic window will then be assembled. When choosing a profile that will be used in the manufacture, one should focus on their functional purpose. When producing plastic windows, different types of profile are also used.

Three-chamber PVC profiles, belonging to the economy class, and aluminum structures are perfect for glazing balconies and loggias. Four- and are used for glazing in regions with a harsh cold climate and in houses that are located near a railway or a noisy highway.

Outcome

Double-glazed windows perfectly perform their functions, being responsible for:

• heat and sound insulation;
• illumination.

They are reliable and safe. Their characteristics directly depend on the quality, so the choice of plastic windows should be given special attention, then it will be possible to hope for their long operation.

A window profile is a frame that holds a double-glazed window. Different types of window profiles differ in the material of manufacture and internal structure. Let us consider in detail the differences and advantages of profile structures, their quality, cost and performance characteristics.

What are the types of windows?

Modern window profiles for double-glazed windows are made of polyvinyl chloride (PVC), wood or metal (aluminum profile). Each of these materials has its own advantages that determine its popularity and cost.

Wooden window profile

Wooden frames represent the most expensive, prestigious design of a window opening. Natural wood requires long drying, thorough impregnation with an antiseptic and protection from moisture. Therefore, the cost of a wooden window is an order of magnitude more than a plastic profile. If the wood is not sufficiently dried or treated incorrectly, then expensive windows can collapse a year after they are installed.

The appearance of natural wood creates a prestigious design, attractive aesthetics. With high-quality preparation, the tree is quite durable and reliable. The best wood for the manufacture of window profiles is oak, larch, alder and pine wood are more accessible.

To summarize the advantages of wooden profiles:

• aesthetics and prestige;
• natural environmentally friendly material;
• good heat capacity.

Disadvantages:

• The possibility of warping, swelling, cracking and other types of destruction;
• high cost;
• High professionalism of the master-manufacturer is required.

An option for using wood for double-glazed windows is wood-aluminum profile. In it, the wooden material is covered from the outside with metal plates. From the inside, from the residential side, the frame shows natural wood, from the outside the frame is protected from moisture by metal.

Aluminum profile

Aluminum window profiles are made with a small number of cameras (two or three). By itself, metal is an insufficient heat insulator, because of this, metal windows are cold. They are mainly used for glazing large shopping areas, airports, but also balconies and loggias. "Warm" metal windows are equipped with a thermal insert, which increases the heat capacity of the profile structure. The cost of such windows is much higher than the "cold" ones.

A metal window is characterized by the following advantages:

• strength;
• low flammability;
• durability.

Disadvantages:

• low heat capacity (for "cold" profiles);
• high cost (refers to "warm" structures).

Two main types of aluminum alloy profiles are in demand in various buildings. A "cold" aluminum profile is used where an inexpensive frame, good strength, and no special requirements for heat retention are needed. The “warm” expensive profile is installed in heated rooms for durable operation in cold winters.

PVC profile

PVC profile is called a plastic window. Its characteristics:

• high thermal insulation;
• moisture resistance;
• various design (thanks to gluing of the laminated film).

Thermal insulation properties are provided by the presence of hollow chambers inside. Due to the resistance of plastic to atmospheric precipitation, it does not absorb moisture, does not swell, does not rot or crack.

PVC has some disadvantages:

• flammability (typical of most plastics);
• the more chambers, the greater the weight of the structure, the higher the requirements for window installation.

Due to the affordable cost, PVC profile has become the most popular material for the manufacture of double-glazed windows. Dozens of different manufacturers are engaged in the production of PVC. Their profiles differ in the number of chambers and the thickness of the plastic wall. Consider what characteristics are used to evaluate PVC profiles.

Characteristics of the PVC window profile

Popular manufacturers of window profiles

1. REHAU is a German manufacturer, has its own production in Russia. It supplies six models of profiles to the Russian market: 3-6 chambers, the width of a standard double-glazed window is 32-40 mm, special glasses are installed in wide double-glazed windows (86 mm), fiber is used. Heat transfer resistance coefficient - from 0.64 to 1.05 (for fiber profiles). The manufacturer regulates that a coefficient of 0.95 corresponds to the heat capacity of a brick wall one meter thick.
2. KBE is a German manufacturer with two subsidiaries in Russia. It produces 8 models of profiles with different characteristics: 3-6 chambers, insulating glass thickness from 32 to 52 mm. The heat transfer coefficient of the KBE profile is 0.7 - 1.04.
3. VEKA is a Russian-German manufacturer, VEKA Rus is a subsidiary of VEKA AG. It produces standard blocks and non-standard design structures for window openings and balconies in accordance with the European RAL standard.

And finally: accessories

Fittings is a set of metal parts that provide a movable connection of various elements in the overall design of the window. The durability of the window product depends on the quality of the fittings.. It is important to know that famous brand manufacturers have cheap lines of lower quality fittings for Eastern Europe.

Types of window fittings:

• Tilt and turn (for opening the window and fanlight tilting).
• The lock and handle is a multifunctional design that fixes the frame in any position with the help of an axis laid inside.
• Parallel-sliding (for retractable sashes).
• Tilt-sliding.
• Vertical sliding.

In addition to fittings, the design of double-glazed windows uses. They provide the necessary insulation against noise and cold.

The choice of a window profile, its main characteristics and fittings is carried out in accordance with the required heat capacity of the window and the price level for its manufacture. The quality of the profile and fittings determines the appearance of the double-glazed window and its performance characteristics: thermal insulation, sound absorption, strength and durability.

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

Window properties

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

Namely:

• the service life of such a window is at least 20 years;
• high soundproof properties;
• positive thermal insulation characteristics;
• ease of maintenance and operation.

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

A standard window block includes two elements - a window frame and sashes, either opening or fixed. Separately, it is customary to single out shtulp windows, they are distinguished by the engagement of the sashes with each other.

Types of sections of metal-plastic windows

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

Metal-plastic windows can be with the following sections:

• Folding section. It is possible to activate the "ventilation" or micro-ventilation mode. This type is suitable for viewing windows located at a considerable height, as well as attic areas.
• Turning section. The sash in it can open inward, which entails a large flow of air. Outward sash opens in rare cases.

• Tilt and turn section. It combines both functions, which makes this type of section very popular.
• blind section. The section cannot be opened as it is fully attached to the frame, but can nevertheless be dismantled.

Different rooms and rooms need different windows, so it cannot be said that there is any universal type of section.

How to choose plastic windows (video)

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 double-glazed windows - they are warmer, more comfortable, and in general, more perfect. Single-chamber windows are used for storage and various 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 do not block the house. Windows can be with a special film that has a reflective dusting, or with a silver-based coating.
• 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 is a must in this case.

• In the absence of natural ventilation, you need to choose a special profile. It is constructed in such a way that even with the doors 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 immune from the attacks of the "windowers". So that they cannot cause harm, you need to arm yourself with additional locking fittings, which are usually installed on handles. A glazing bead is also 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 pasted over with a special impact-resistant film. In some cases, armored glass is ordered.

These are just the main selection criteria, which, in principle, are enough not to miscalculate with the acquisition.

The quality of metal-plastic windows - what to look for

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

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

As for the color, the most popular is of course white. But even if the seller cannot offer a profile of your preferred color, today many of the most paste over it with a special film or acrylic varnish. But the window will definitely look better if a coloring pigment was added to the PVC during the manufacturing process of the profile.

How to choose a good seller

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

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

• Request 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 long enough.
• Do not be lazy to look at the showroom of the company that manufactures windows.

Nobody canceled word of mouth, so listening to the reviews is never superfluous.

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

Good choice!

Rules for choosing PVC windows (video)

Attention, only TODAY!

A lot of materials on the topic of window installation describe the main stages of work. However, the installation of plastic windows is not just fastening the frames to the anchors and foaming the seams. When it comes to replacing windows yourself, there is much more you need to know. What types of windows exist, read further in the article.

Choose windows wisely!

Not all windows are the same. Yes, most of them have an adjacent design - a white matte frame and a sparkling double-glazed window. But if you look at the root, completely different products can be hidden under the same shell.

Types of windows by opening method

According to the method of opening the window is divided into:

blind windows

Installation of plastic windows of this type can be carried out only in rooms in which air exchange is provided by its own air conditioning system. A huge minus is the difficulty in cleaning the window from the outside. Plus - the reliability of the design. They can be used in shopping and entertainment buildings, industrial buildings, as well as in stairwells and technical rooms.

Traditional design

The traditional design of the window allows it to be opened outwards. It can be supplemented with the ability to open a window inside the room. Easy to clean and durable.

Hinged windows

Hinged windows allow you to leave the window in the ventilation mode. However, if this is the only function of the window fittings, it will also be problematic to clean it.

Tilt and turn system

Tilt and turn window system is one of the most functional.

sliding windows

Installation of sliding windows allows you to win usable space in oversized rooms, as well as perfectly complement the design of any room.

Figure 1 - Types of windows by opening method

Types of windows by design

• Single glazed windows.
• Double-glazed windows are also divided into twin-panel and split-panel windows.

This characteristic will significantly affect the soundproofing properties of the window system.

Types of windows by source material

• Wooden windows. An age-old classic is now given a second life with a sustainable building brand. Manufacturers: Wicknorm (Germany), Schöb Fenster (Germany), KNEER (Germany).
• PVC - plastic windows. The installation of eurowindows today is associated precisely with the PVC profile, however, the “eurowindow” is understood as an improved window system that provides greater sound, heat and vapor barrier through the use of modern technologies and materials. Producers: VEKA (Germany), REHAU (Germany), DECCO (Poland).
• Aluminum windows are installed in most public buildings and industrial premises. Producers: ANTON WETZEL (Germany), TUR-PLAST (Poland).
• Metal-plastic windows. Often this material is confused with simple PVC windows. However, there is a difference - the design of the metal-plastic window is stronger due to the reinforcing amplifier placed in the PVC profile. Producers: Baufen (Bulgaria), KBE (Russia, Germany).

Types of windows by purpose

1. noise protection;
2. impact resistant;
3. tinted;
4. energy saving;
5. semi-mirror.

Separately, I would like to say about energy-saving windows. It is understood that these windows on the inside will be coated with silver atoms, which will create a reflective effect and help retain heat in the room.

However, when they try to sell you a window, hanging a thousand characteristics on the proposed product, be careful: what sellers call an “energy-saving” window may actually not be made using energy-saving technologies at all and even have nothing to do with them.

Photo 1 - Making windows

The same applies to fire windows. Not every window is extremely flame resistant. Glasses and profiles of fire-resistant windows, by the way, also have their own characteristics - fire resistance limit (СВС 15-60), package thickness requirements (16-38 mm), weight norms (38-76 kg / m²), etc.

Scheme 1 - Window fire block

If you are really interested in buying a fire protection window, take a look at the catalogs of certified products from Schuco, UAB Bavaria Dom and CORAL.

If we sorted out the choice of the type of facade windows a little, then they didn’t even say a word about roof windows (especially about the choice of a dormer window). Firstly, this is a separate type of window products, because there are much more requirements for it: due to the fact that the design of the dormer window becomes part of the roof, it must at least have a safety class III and be accompanied by a complete set of materials for installation. Here, without unnecessary savings, you should trust only proven brands FAKRO, ROTO or VELUX.

Window installation services: a full package of services and nothing else!

It is risky to let the purchase, and even more so the installation of the window, take its course. If you did not have the relevant experience, you can easily miss the measurements or the choice of double-glazed windows.

And if you decide to seek help from specialists, please note that you have the right to demand that the entire sequence of work be completed:

1. Window lock.
2. delivery.
3. Window installation.
4. Slope trim.
5. Service.
6. Warranty.

If you are faced with a company that does not provide the full range of services, it is better to look for another contractor: for example, selling windows without installation is unreasonably unprofitable for you, because you yourself will at least have to look for workers. In addition, the manufacture and installation of windows must comply with GOST, and in most cases only certified companies can guarantee you high-quality manufacture and installation in accordance with all the rules. Otherwise - how do you know if everything is done in accordance with the norms.

Moreover, before starting work, you should know exactly what you will get as a result: discuss with the workers what is included in the cost of the basic window installation package, and what will need to be paid separately.

Figure 2 - Ventilation valve in section

Additional opportunities can be offered to you even when placing an order at the office of the company. Never refuse to consider such proposals: for example, a good double-glazed window should not fog up, however, an additional precaution may be to install valves on the windows (special ventilation systems) or, say, for greater control over the ventilation function of the room, an additional option is offered - installing a comb on the window profile.

The purchase will be worthwhile if you contact the actual representatives of well-known brands − REHAU, VEKA(front windows) or VELUX(roof windows), etc.

All of them - Veka, Velux, and Rehau, as well as any other respected manufacturer, provide a list of offices and representative offices in a particular city of the country on the official website of the company. Therefore, you can be sure that you really entrusted the production and installation of eurowindows for your apartment to professionals.

Window mounting materials

It is important not only WHO provides installation services, but also WHAT the workers use. If you are faced with the installation of windows for the first time, do not trust yourself with the choice of materials for installation work.

Remember! The manufacture and installation of windows is a matter of professionals.

Even if we are talking about buying mounting foam or sealant, you should not go to the construction market without an exact list indicating the characteristics of each product. Moreover, most world-famous manufacturers are themselves happy to provide their customers with the entire set of materials, the purchase of which greatly simplifies everything or, in extreme cases, recommends a company whose profile is the installation and installation of plastic windows.

Installation of window blocks: what you need to have on hand

Installation of window blocks is impossible without:

• mounting foam;
• silicone;
• dowel-nails;
• anchor plates;
• self-tapping screws;
• plasters.

Continuing the topic, let's give an example. All the necessary materials for window installation can be found in the catalogs of many manufacturers, but one of the companies that provide materials and components for window installation in full is Bauset: polyurethane foam, silicones, cleaners and guns for them, mounting tape, ebbs, window sills, slope systems, window chemicals, mounting aids - everything, up to mosquito nets and platbands, can be found in the manufacturer's catalog.
