How to choose a profile for plastic windows. Which profile is better for plastic windows - an overview of the parameters and manufacturers. Plastic windows: everything that is important to know

Loud slogans of numerous sellers of plastic windows confuse any buyer. Each manufacturer presents their products as the best. Is it really? The answer to this question is known to those who are familiar with the criteria for the profile of windows from.

The ability to notice the first signs of fakes is a guarantee not to become profit for fraudsters.

They entered the construction industry very firmly. Very soon, wooden windows will be a curiosity that you will hardly see anywhere. And there are explanations for this.

The advantages of plastic

Firstly, plastic is a cheaper material than wood, secondly, it is convenient to use, and thirdly, it is very easy to make repairs in such windows.

Replacing any part of the window: sash, glass, opening mechanism takes a couple of minutes, and therefore is inexpensive.

PVC window specifications

They are determined by the type of his profile, of which there are a lot. The facade of the windows can be exactly the same, but the functionality and quality are different, due to the constructive profiles. Then, if there is a firm intention to acquire plastic windows, which profile is better to choose?

Brands

A company with a well-known name cannot afford absolutely disgusting products. Most likely, these will be one-day firms.

Therefore, give preference to products from manufacturers who have experience and have collected a list of positive reviews. In addition, the risk of stumbling upon a low-quality product by choosing the windows of a large factory is much less. Small firms are unlikely to buy expensive productive and technological equipment.

REHAU windows

A very famous manufacturer of plastic windows. Deserved reviews, a minimum of scrap, constant training and improvement of its employees, innovative development of manufactured designs. They cooperate with enterprises only if they have good equipment.

Interesting! Manufactures certified by REHAU are constantly tested. Therefore, the risk of buying a low-quality product from the hands of a company partner is very small.

VEKA

Also a representative of German, loved all over the world. They produce a white and colored profile that is able to stay tinted with prolonged exposure to sunlight.

The seal is made of natural rubber and is able to withstand very low temperatures. Models are sold from 58 to 90 mm thick. In the price range, VEKA and Rehau are approximately the same.

KBE

It ranks third in our ranking after the first two companies. There are small shortcomings: the number of rejects is slightly higher in comparison with the previous giants, there may be delays in deliveries, they do not suit their partners with inspections.

However, the products of this company are considered environmentally friendly and are recommended for installation in kindergartens and hospitals. The service life of such windows is around 50 years. There are offers, both luxury and economy classes. The profile is produced in widths from 58 to 70 mm.

Trocal

The company is one of the pioneers in the production of PVC profiles. They offer a huge assortment for decorative possibilities.

MOTNTBLANK, PROPLES, BRUSBOX

These companies are still gaining their reputation. There are already reviews on their products on the Internet.

You can even select a forum and ask questions of interest to the owners of such windows. The main advantage here is an affordable price.

When installing plastic windows, the profile plays no less role than the glass unit itself. The profile is the basis of all window construction... That is why it is worth approaching his choice extremely responsibly. Due to the large selection of profile systems, many are lost and do not know what to look for.

All profile products are divided into window and pedestal. Window profiles are the foundation for glass unit fastening. That is why choose quality proven models.

A support profile for plastic windows is a plastic structure on which the window is attached. A window sill is attached to the base (base) profile. Also, this system has a section for attaching drainage. The height of the stand profile is often 30 mm. The installed structure is hidden by a window and a window sill.

The base profile differs by price category. Budget options are made from recycled plastic. More expensive systems are made of white plastic.

Actually, recycled material in this case, it does not affect anything except the price. Therefore, many professionals recommend taking exactly budget options.

For plastic windows, two types of profiles are used: aluminum and PVC. The pvc profile for plastic windows is much more economical, and therefore more popular. They have good heat and sound insulation. At the same time, the pvc construction is durable and beautiful. It allows you to perfectly fit the frame without gaps.

Plastic profiles for windows are divided into three main price categories:

• Economy.
• Classic.
• Premium.

Economy class profile systems are the cheapest. In terms of quality, they are significantly inferior to the other two. Economy class constructions can be installed in rooms that are not influenced by external factors.

"Classic" differs from "Premium" in to a greater extent, the price. Their quality is about the same. The only thing that distinguishes them is that premium installations often have completely useless "bells and whistles" that do not affect the durability of a metal-plastic window.

When installing, many people have a question, which profile is better for plastic windows.

When choosing, first of all, pay attention to the main indicators:

1. Uniformity.
2. Thickness.
3. Number of air chambers.
4. Profile width.

The uniformity of the product can be assessed "by eye". Good uniformity indicates quality products. At the same time, the graininess of the profile system often indicates a fake design.

The thickness of the plastic profile has a significant effect on the thermal conductivity and sound insulation of the product. It must be at least 3 mm. The thickness of the window base directly depends on the number of air chambers.

Profile chambers are small voids filled with air. This structure of these structures contributes to good thermal insulation. Most often, firms make profile systems with the number of chambers from 2 to 5. But there are seven-chamber designs. They are intended for the far north.

• Two-chamber profiles are mainly used for glazing balconies and loggias. They are considered the most budgetary.
• For glazing of premises, the most optimal in terms of quality and price are three and four-chamber products.
• Five-chamber structures are considered the warmest. But they have a significant drawback - a rather high price.

Also, many experts claim that a large number of air chambers negatively affect the resistance of structures to external factors - sun, wind, rain. Such items can turn yellow and crack. In addition, the more cameras there are in the product, the softer it becomes. The structure may not support the weight of the glass unit.

The profile width of plastic windows can vary from 60 mm to 90 mm. But the most optimal in terms of price and quality are 70 mm designs. In terms of quality, they are not worse than their wide counterparts, but they have a much lower price.

Market Review

All these requirements can be met by products of several companies. Therefore, many are wondering which company profile is better to choose for plastic windows.

In the modern market, there are a huge number of manufacturers of metal-plastic structures. But experts advise choosing well-known proven firms. The "promoted" companies seriously monitor the quality of their products. Choosing their products, you will definitely be sure that you have avoided a low-quality fake.

Choosing a company for the production of profiles

Choose a trusted manufacturer

By quality and price, you can create a conditional rating of plastic profiles for windows.

The profile of the KBE company is in the greatest demand in the modern market for metal-plastic structures. This German company was one of the first to appear on the CIS market. It presents both budget options and more expensive ones. KBE products are environmentally friendly and are recommended for installation in kindergartens and medical institutions. KBE structures are considered one of the most durable. Their service life is 40-50 years.

Rehau profile is very popular. This is a quality German company. In the designs of this manufacturer, high-quality, environmentally friendly materials are used. Rehau also added a climate control function and a locking system to their designs, which prevents entry into the house through the window. The only drawback of Rehau products is the low sash height.

The well-known company Veka has been losing ground recently. This is due to outdated designs compared to competitors. But the most important drawback of this manufacturer is the use of lead in the manufacture of structures. This radioactive element has a very negative effect on the human body, causing various diseases.

Lovers of interesting design solutions will appreciate the designs of the company Aluplast. This manufacturer presents more than 40 variations of decor. Aluplast is constantly developing various innovations in order to more and more meet consumer requirements.

The disadvantage of these systems is their tightness. On the one hand, this contributes to good thermal insulation. On the other hand, such tightness contributes to the accumulation of vapors in the room and the room must be constantly ventilated.

Not very popular in the CIS countries and the first company that began to manufacture plastic windows - Trocal. The manufacturer's designs are strong enough, but special distinctive features from competitors do not.

Who else is striving for the market today?

A novelty on the market of metal-plastic structures in the CIS countries is the Lg profile for plastic windows. Indeed, everyone is accustomed to seeing only the equipment of this company. In fact, many countries have already appreciated Lg products as good value for money.

These window systems have good thermal insulation and a long service life. The manufacturing company controls every stage of the product manufacturing, which is why they call their products "reliable".

Whichever profile of plastic windows you choose, you should take care of the product seriously. Careful use metal-plastic windows will extend their service and will delight you for more than a dozen years.

To DIFFERENTLY simplify your profile selection be sure to watch the video below. At least his first minute.

If you want to understand the criteria for choosing a PVC window, then one of the first indicators that experts recommend paying attention to is a polyvinyl chloride profile. Products are presented in various classes, each of which has its own characteristics. Having become acquainted with them, you can choose the optimal type of window structure.

What should be a modern PVC window profile

Today, the main European quality standard for PVC window profiles is RAL-GZ 716/1.

It defines the following parameters of polyvinyl chloride products:

• class A: the outer walls should be 2.8 mm thick, the inner ones - 2.5 mm;
• class B: the thickness of the outer walls should not be less than 2.5 mm, internal - 2 mm;
• class C: external and internal walls can be of almost any wall thickness.

Naturally, it is better to give preference to the profiles of the first two classes, which are distinguished by excellent parameters.

But if class C products are used, then only for installation in technical rooms or for temporary service.

What is the difference between class A profiles and class B?

Although the wall thickness of the profiles of these two classes differs slightly, their consumer characteristics are very different. When tested, products of class A in many parameters are ahead of products of class B. If we talk about compliance with the DIN EN 12608 standard, the decrease in strength for a profile with a reduced wall thickness is 25%, and the resistance to pulling out self-tapping screws is also reduced by 20%, by 15% the ability to maintain its shape decreases.

Therefore, PVC windows, in the construction of which a class B profile is used, do not last as long as products of the first category.

And yet, the class B profile has an important advantage - a more affordable cost.

Which plastic window profile is better to choose? Selection tips and manufacturer ratings

It is for this reason that such products are very popular.

Benefits of each class

Almost all manufacturers of profiles for PVC windows, whose products are presented in the markets of post-Soviet countries, offer products of classes A and B. Only the manufacturer VEKA offers consumers products of only the highest category.

Thanks to the different types of profiles, their manufacturers try to satisfy the various wishes of their customers.

Therefore, each consumer can choose the most suitable product.

A class A profile will be the best option in the following cases:

• when the client is used to receiving only the best and is not ready to compromise on quality;
• high cash costs are not a problem.

The Class B profile may be preferred in the following cases:

• there is no need for a large margin of safety and thermal insulation indicators, which are inherent in products of the highest category.

  This choice is fully justified for the installation of plastic windows in non-residential premises, buildings with seasonal residence or at industrial facilities;

• the quality of the window structure is determined not only by the profile class.

  For example, an increase in strength can be achieved using reinforcement. And the installation of a double-glazed window with several cameras will help to increase the heat-saving parameters.

Russian legislation allows glazing of residential real estate using profiles of classes A and B.

Thanks to this, the consumer can make his choice, taking into account the purposes and purpose for which the plastic window is purchased. The financial side of the issue is also of no small importance. Having weighed in detail all the reasons, you can opt for the most suitable form profile.

Which profile is best?

It all depends on the conditions for using the profile and the quality of manufacture of the metal-plastic structures themselves. The only difference is that the quality of the profile itself can be influenced by the human factor.

Data taken from the Internet.

Everything you need to know about choosing a PVC profile

For the manufacturer of window and door designs made of plastic, important indicators when choosing a supplier of components is the quality of materials required for production, appropriate equipment and tools that employees have to work with.

Most properties of the finished product are mainly influenced by pVC characteristics profile - the basics of the construction of a window or door. Why does the profile determine the reliability and durability of the window?

What types of profiles are currently available? How to choose a PVC profile?

Width and thickness of a plastic window profile

The owner of an apartment with a window made of a wooden frame that has dried up over decades of operation, which, due to impressive cracks, often had to be sealed with strips of paper for the winter in order to preserve heat, dreamed of changing it to a white sealed PVC structure.

In the late nineties and early 2000s, in Russia it was considered very prestigious to have a plastic window at home, and its installation was certainly included in the estimate of the then favorite expression "renovation", which not everyone could afford. The presence of a plastic window then emphasized the status of a house tenant or office owner.

Over the years, plastic windows have become cheaper, which means they are more accessible to a mass audience of buyers, and now plastic windows and doors are installed almost everywhere. Windows in secondary housing apartments are being gradually replaced, developers order more often plastic window and door systems from manufacturers, office partitions and entrance groups.

The advantages of PVC windows over windows with wooden frames became obvious to the consumer:

1. it has become quieter and warmer in houses with plastic windows;
2. the need to insulate and paint a wooden frame every year has disappeared;
3. a plastic window is cheaper than a wooden counterpart.

If at the beginning of the formation of this market, the end consumer did not impose special requirements on the quality of the plastic window - the main thing was the fact of its presence at home, then over time he began to understand the installation companies, the number of which grew in accordance with demand.

Since the window of one brand is still different from the window of another, the consumer now has to study the issue more deeply - the client himself asks the question of the quality of components for assembling the finished product. Therefore, at present, the developer and the company for the installation of windows have to meet the increased requirements of consumers and are more responsible in the choice of manufacturers of PVC profiles, glass units and accessories.

About PVC material for window profiles

Polyvinyl chloride (PVC) is a white plastic, a thermoplastic vinyl chloride polymer.

Chemical formula: [-CH2-CHCl-] n. PVC is a product that is a chemical compound of carbon, hydrogen and chlorine, containing approximately 43% ethylene and 57% combined chlorine, which is obtained from rock and table salt.

We come across polyvinyl chloride products everywhere every day.

Housings household appliances, stationery, car parts, children's toys, disposable tableware, medical supplies, food packaging - all made from plastic. The material does not emit harmful substances, is chemically resistant and safe for humans. If we consider the environmental side of the issue, then used PVC items can be recycled many times and get a second life in new things.

Due to its versatility, barrier properties and environmental friendliness, PVC is also suitable for the manufacture of profiles for windows.

In its original form, PVC is a finely dispersed white powder. But pure PVC is not enough for a window profile. Frost resistance and profile strength is provided by various additives. Each manufacturer has its own recipe for the technological composition of stabilizers and fillers.

PVC profile manufacturing process

PVC profiles are made by extrusion. On the extruder, the polymer mixture is heated to the required temperature, turning into a plastic liquid mass.

This mass is pressed through the forming tool, from where the profile blank comes out. Then it is pulled through the calibrators and cut into the desired lengths.

Large manufacturers of PVC profiles carry out final control of geometric dimensions and weight running meter every hour.

A profile that has deviations above the permissible technological regulations is sent for recycling.
Since during the extrusion of window profiles, a thorough homogeneous mixing of all component parts formulation, then a material can be obtained, the spectrum of properties of which varies in the widest range. At the same time, the use of additives does not change the fundamental properties of PVC as a thermoplastic, which are decisive in the design of window structures.

Types and characteristics of PVC profiles

1. PVC profiles differ in the field of application: window, balcony, door and facade.

   For each of the options, corresponding profile designs have been developed.

2. Depending on the number of chambers, there are three-, four- and five-chamber profiles. These are the most popular options. Less common are two-chamber profiles (they are installed mainly in unheated rooms or as partitions). Profiles with six chambers or more are used in regions with severe frosty climates.

   The more chambers in the glass unit and the profile, the higher the thermal characteristics of the window units.

3. PVC profiles also differ among themselves by such an indicator as width, which depends on the number and size of air chambers.

   The width of the PVC profile system can vary from 46 mm (for two-chamber profiles) to 130 mm. Wide frames protect the slopes from freezing, and in the case of using profiles with an intra-profile self-ventilation system, they normalize air exchange, remove excess moisture, move the window into the room, closer to heat flows.

4. In addition to the width of the profile itself, there is such a parameter as the thickness of the outer (front) walls, which affects the strength characteristics of the PVC profile.
5. The penetration depth of the glass unit is another indicator that affects the performance of the window.

   At the junction of the glass and the profile, a "cold bridge" forms and heat loss occurs. In frosty weather, condensation may form around the window. In order to avoid the so-called "edge effect", profile manufacturers increase the depth of the glass unit up to 25 mm.

6. The reinforcing element in the profile of the frame, sash and impost is the basis of their stability under conditions of exposure to wind and heat loads. Each profiled part of the window must have a metal reinforcing liner made of galvanized steel, rolled thickness and configuration corresponding to the system requirements.
7. The aesthetic characteristics of the window are important for the consumer. To satisfy this request of the customer of the window and door system, the choice of PVC profile should be based on its resistance to ultraviolet light, the choice of color design

   To prevent the window from turning yellow over time, the manufacturer must add a sunscreen component. Currently, in addition to color, you can also choose the texture of the plastic profile, for example, for wood. Or choose the color of the entrance group in accordance with the corporate identity of the enterprise. Plastic windows can be not only rectangular. Arched openings can also be closed with a PVC structure. Round, triangular, polygonal windows are available to fulfill the architect's idea.

How to choose a PVC profile

1. First, decide on the purpose of the future product.
2. Study the climate in the area where the windows or doors will be used.
3. Budget your order.
4. Determine the manufacturer's brand and profile supplier.

   Study their assortment: will their profiles "cope" with the tasks. Specify what equipment the production is equipped with, and from what raw materials the plant produces profiles. As a supplier, it is safer and more profitable to choose an official representative of the plant, who has a set of preferential conditions and guarantees.

Narrow profile from VEKA

Today, plastic windows not only protect the premises from cold, wind and noise, but also have aesthetic value.

Plastic windows: everything that is important to know

Many factors affect a person's mood, including the beautiful view from modern window... in Vyborg, the climate does not spoil too much with sunny days, but every resident dreams of having as much sun as possible in his apartment in clear weather.

Thanks to the unique narrow profile VEKA EUROLINE from the Vyborg Window Plant company, the dream of Petersburgers becomes a reality.

The narrow VEKA EUROLINE profile is not much different from the standard profile of a similar model, but according to its parameters, its height of the profile installed on the sash, frame and impost is significantly lower. This information can be viewed in the table.

VEKA EUROLINE profiles in comparison

The use of a narrow profile in the installation of plastic windows does not at all reduce their thermal insulation qualities, which is important for a simple user during operation.

According to the table, the installation depth of the standard and narrow profiles have the same dimension, namely 58 mm. The number of cameras used in both variants is three. And you can get an answer to the question of the topic "NARROW PROFILE" by phone (go to contacts) or by writing us a letter.

Production of PVC windows

To become a window, the PVC profile must be properly processed and connected in one structure. The process of manufacturing a window or door block from plastic profiles is the same and represents a transport chain of a large number of operations.

Only strict adherence to technology and standards (GOST) at the assembly ensures the quality of the finished product. But about all this is wonderful.

To obtain a clean, correct window and geometric window, it is important to build a manufacturing process based on quality raw materials. In particular, high quality PVC profiles, reliable hardware and energy efficient double glazed windows.

PVC supply and storage

The PVC profile is supplied from the manufacturer in the store with a large pallet.

Frame, fenders, impost, glazing - all these window elements bring whips packed in six-meter pallets. To make a window out of them, they must be cut into pieces of the required length in accordance with the cutting specifications. They used to be stored in processor rooms equipped for this purpose.

Storage of PVC profiles

In the future, the profile will be focused on a window production line where a new plastic window or PVC doors are produced.

He saw the profile

The profile is cut at a 45 degree angle and then welded into a frame or sheet.

The profile used for the production of windows has an internal space, which makes it more resistant to freezing, but at the same time weakens the power properties. In order to make the window structure more stable and resistant to possible loads, a reinforcing steel frame is introduced into the central profile chamber.

This is also called a rebar profile.

Steel layer installation

Reinforcement (or reinforcement) of PVC is a mandatory process for all types of windows that are more than 400 mm on the side.

Otherwise, the profile will not be stable even in the case of linear expansion in case of temperature drop or mechanical action. However, for the manufacture of certain types of plastic windows, the reinforcing frame can be excluded.

There is a round, round and arched image for this type of product. Profile improvement

Plastic window production

Arched windows and other PVC windows with a certain radius of curvature are made by bending in special tables.

Before bending the plastic whip, it must be heated to a temperature of 150 degrees Celsius. The bend becomes compatible while maintaining the shape and geometry of the internal reinforcement.

Profile bindings in frames and skirts

When plastic profiles of a certain size are cast and reinforced with a reinforcing coating, they must form one window box: a frame or a sheet.

Welding is the most typical joint profile. The blocks are placed on the welding machine in the required sequence, their edges are heated to the melting point and pressed together.

the composite angle profiles between the welding power are not only worse than the strength of the corresponding profile, but also higher (as in tests carried out in experimental laboratories).

However, the plastic-filled profile looks extremely unaesthetic and the next step must be cleaned up. For this purpose, use special cutting machines (grinding).

The blades and sawing exercises (cleaning) are configured to remove excess plastic and do not touch the main structure. After this step, the window frame and wing are prepared for the next procedure - fitting the fittings.

How to install accessories on PVC windows

Fittings - a set of metal elements (hinges and locking devices) that allow you to open and close the wing.

That's all the window cannot be moved without - and there is additional equipment.

Elements of this type are mounted on the frame and on the sheet.

Which profile is best for modern plastic windows?

To ensure that each item on window frame matched to blocking the frame - all these processes are carried out in accordance with the previously marked sketches in accordance with the recommendations of the accessory manufacturer.

At this stage, the window is almost finished with the look and functionality, the only thing missing until it is fully prepared is the clear glass that is installed in the next stage of the conveyor belt.

Glazing, installation of double glazed windows

Speaking about the glass filling of modern metal-plastic windows, it is worth mentioning the glass unit.

A double glazed unit, unlike ordinary glass, is not only one sheet, but several sheets of glass, fixed at a distance and sealed.

That's why the name is double glazing.

Today glass blocks are made of different glasses, and the filling of the gap between the glasses can also be different. In the warmest (energy efficient) double glazing models, an inert gas argon is induced in the cavity between the glass plates. It is heavier than air, so it is best to prevent freezing and the hot summer sun in summer in winter.

We can talk about how the window turned out to be good at the end of fixing the last glazing.

The design (window or door block) should now be checked correctly. This is the task of the QC inspector.

The product and the sealed unit show no signs of damage, the protective film is peeling, the functionality is in the order of state - this window is suitable for sending to the customer and there are hardly any complaints.

How to distinguish a high quality window with a low quality. Video.

When installing a window block, a profile system is selected. Although the profile occupies no more than 20% of the product area, this is the main component on which the reliability and durability of windows depends. Outwardly, all profiles are not very different from each other, but the difference is hidden in the structure of the structure and the material of manufacture.

Features:

The window structure includes 3 parts - profile, glass and fittings. Window profile Is a stable support that holds the glass unit. Frames and window sashes are made from it, which bear the load of the entire structure.

The following characteristics are presented to the profile:

• The material of manufacture must be with a low coefficient of thermal conductivity so that the frame does not freeze.
• The level of thermal expansion must match the coefficient of linear thermal expansion of the glass. It is 0.000009 m / m ° C. The difference in the expansion of the profile and the glass should be minimal so that there is no stress when the materials are stretched. This leads to premature wear of the seal.
• High modulus of elasticity. Various weather conditions can lead to deformation of the structure. The higher the elasticity of the profile, the more stress the material can withstand.

Profile structures are made of various structures. Profiles can be solid and hollow. Corpulent ones are made from solid material, usually wood. Hollow structures are separated by partitions to form chambers. The bridges between the chambers serve as stiffeners, increasing the strength of the profile.

The chamber adjacent to the street serves as a drain for condensate formed from temperature differences. The central large cavity bears the main load on the body. The chamber adjacent to the room is intended for installation window fittings... Each chamber filled with air or other thermal insulation material performs thermal insulation functions.

Additional chambers are needed to improve sound and heat insulation characteristics.

Views

The window profile differs in the type of material from which it is made. There are profile systems of the following types:

• wooden;
• aluminum;
• fiberglass;
• polyvinyl chloride.

Different tree species are a classic proven material for the manufacture of window frames. For the assembly of profiles, glued beams are taken from cedar, pine, larch, oak, alder. The tree meets all the characteristics required for a window profile. The thermal conductivity coefficient averages 0.2 W / m * K, the elastic modulus is 9-10 GPa. It does not expand when heated, but under the influence high temperatures able to catch fire.

When installing wooden profiles, the following advantages can be distinguished:

• comfortable indoor microclimate due to natural air exchange up to 2.7 m3 per day;
• wood does not attract dust, since there is no electrostatics;
• aesthetic appeal;
• the strength of the structure determines the density of the tree - 0.5-0.6 t / m3;
• the ability to repair surface defects;
• depending on the type of wood, the service life is from 30 to 90 years.

Wood structures retain heat well and are environmentally friendly.

To get a quality product, you need to take into account the features when working with the material. Additional drying, treatment with antiseptic and fire-retardant primers leads to an increase in the cost of wooden windows. The negative side is its swelling at high humidity. When the temperature and humidity environment in the room changes, condensation may occur. The accumulation of moisture causes stains on the wood.

Aluminum profiles are lightweight and durable and consist of two or three chambers. The main plus when using them is fire safety. The metal window has a high thermal conductivity - 140-190 W / m * K, which makes it unsuitable for operation in harsh northern conditions.

To increase the heat capacity, a polyamide thermal insert is included in the design of aluminum profiles, which leads to a massive and more expensive product. A high coefficient of elasticity (up to 70 GPa) allows it to be used for glazing of retail premises, public buildings, balconies.

The fiberglass profile is made of PVC and fiberglass, which gives it special structural strength, corrosion resistance and chemical inertness. Glass composite with a thermal conductivity of 0.3 W / m * K has a coefficient of thermal expansion of 5-14 * 10-6 m / m * C, which corresponds to the level of glass. The coefficient of elasticity of 20-40 GPa allows good resistance to stress during deformation of the profile structure.

The fiberglass profile is not widely used due to its high cost. It is one third higher than popular plastic counterparts. Also, the production of glass composite windows is complex. The lack of flexibility of the material does not allow it to be used for the manufacture of one-piece arched elements.

Polyvinyl chloride profile structures can be completely made of polyvinyl chloride or reinforced with a metal liner. Often reinforced profiles are called metal-plastic. For the insert, galvanized steel with a thickness of 1.5-2 mm is used. The metal gives strength to the profile structure, levels the expansion of polyvinyl chloride when heated, increases elasticity and resistance to stress and deformation.

The type of reinforcement is determined by the size and weight of the entire window. Structures with a profile length of less than two meters can be equipped with an open-loop liner, where two or three walls are reinforced. For a massive window, a closed-loop metal insert is installed. There is no reinforcement for profiles less than 60-70 cm in size.

The following technical characteristics are distinguished for PVC profiles:

• Low thermal conductivity values \u200b\u200bof 0.15-0.16 W / m * K allow it to be a leader among all materials.
• The density is more than 2 times higher than that of wood - 1.4 t / m3.
• The high coefficient of linear expansion 60-70 10-6 m / m * C and the low modulus of elasticity 2.8 GPa are compensated by the profile reinforcement.
• Chemical resistance to alkalis and fats. Relative resistance to solvents and acids.
• The number of chambers is from 3 to 8. The chambers affect the heat-insulating and noise-absorbing qualities, strength and rigidity of the structure.
• The filling width determines the type of glass unit to be installed. The depth of the seat from 15 mm inward allows you not to fog up and freeze the glass.
• Operating temperature - from -60 to +75 degrees.
• The flexibility of the material allows you to give any geometric shape, even a circle.

The PVC profile can be painted in different colors. The standard is one-color painting in white in bulk. Also, color change is possible when laminating with films. different shades... The color will adhere more firmly to the surface when the color film is applied by the coextrusion method.

According to GOST 30674-99, for window blocks made of polyvinyl chloride profiles, the thickness of the inner and outer walls differs by classes:

• Class A with outer walls - more than 2.8 mm, thickness of inner walls - more than 2.5 mm;
• Class B has a wall thickness of more than 2.5 mm and 2.0 mm, respectively;
• Class Cdoes not have strict standards for the thickness of the case.

The outer walls form the profile body, they are visible from the side of the room and the street. One inner wall is adjacent to the mounting wall, the other is located inside the structure and serves as a support base for the glass unit.

Plastic profiles stand out for their positive qualities:

• resistance to high humidity;
• anti-corrosion qualities of the material;
• do not fade from sunlight;
• environmentally friendly, do not emit harmful substances for human health;
• service life up to 40 years;
• they are easy to care for and wash.

Among the negative sides, there is a complete tightness of the structure, which prevents air circulation in the room and contributes to the formation of condensation on the glass units.

Frequent ventilation of the room will help to remove the deficiency, if additional ventilation is not installed. Also, plastic cannot be repaired, scratches cannot be masked.

Dimensions

The width of the profile system, called the installation depth, can vary from 58 to 124 mm.

The following profile sizes are distinguished:

• 58 mm - the classic version that meets the standards;
• 70-80 mm - extended modification for high-rise glazing with improved thermal insulation characteristics;
• 90 mm - energy-saving profile with 5-6 chambers and the ability to install a glass unit up to 5 cm.

In a three-chamber profile, the width is 58-60 mm. More cameras require frame thicknesses over 70mm. With a narrow profile, the size of the installed glass unit cannot be more than 32 mm. With an increase in the installation depth, the thickness of the glazing expands, increasing the thermal insulation of the window.

Not always a large profile width corresponds to multi-chamber. The capacious design with 3-4 chambers retains heat better because the air volume is greater.

How to choose?

When choosing a window profile, you first need to decide on the material of manufacture. If an aesthetically attractive appearance and high standards of environmental safety are important, then it is better not to choose a wooden profile. Modern fiberglass and aluminum windows suitable for progressive interior design. A polyvinyl chloride profile system can be an acceptable solution.

The choice is made according to the following criteria:

• Profile size. It is characterized by the installation width and is determined by the installation location and operating conditions.
• Available budget.
• Number of cameras.
• Products have a certificate.
• Depth and width of the glass unit seat, profile class.
• The presence of reinforcement.
• Appearance and color.

The most important indicator for keeping warm in the house is the profile width.

It depends on the atmospheric conditions of the local climate. In the southern regions, a narrow profile with a depth of 58-60 mm can be installed. In temperate climates, systems with a width of 70-84 mm are suitable. In harsh northern conditions, it is preferable to install an energy-saving profile with a width of 90 mm or more.

You also need to take into account the location of the profile system. For an unheated balcony or loggia, a narrow profile of 58 mm or less is suitable. On high-rise floors, a 70 mm profile is installed. A profile with a depth of 58-70 mm is suitable for public and commercial buildings. For suburban individual construction, 70-90 mm systems are used.

For many consumers, the main criterion for choosing a window profile is its price. Therefore, when choosing well-known brands of a profile produced abroad, the cost may not coincide with the planned budget. In such a situation, the best solution would be a profile that meets all the characteristics, produced in Russia.

Depending on the price category, there are several classes of profiles:

• economy;
• standard;
• exclusive;
• elites.

Economy-class profile structures are the most budgetary ones with low quality and thermal insulation characteristics, no more than 58 mm wide and wall thicknesses of class B or C. Class Standard corresponds to GOST and European standards, three-chamber, with a width of 58-60 mm. The most correct decision in terms of quality and price.

Elite profiles with an installation depth of 70-80 mm allow you to mark 40 mm glass, class A walls, 5 chambers. Thermal insulation is 15-20% higher than that of Standard profiles. The exclusive profile system is 2 times warmer than the elite one. The most expensive choice, emphasizing the status of the owner. Width 86-90 mm, 6-7 chambers and double-glazed windows up to 5 cm. The number of chambers corresponds to the profile width. A 58mm profile cannot contain more than three cameras. The depth of 70 mm allows for 3 to 5 air chambers. The 90 mm profile has 6-7 chambers. The same profile width, containing a different number of chambers, insignificantly affects the thermal insulation characteristics of the entire block.

Quality window profiles are RAL certified. A certified product is the key to long-term operation and compliance with all manufacturing cycles. The factories where the products are manufactured also receive a certificate of quality management ISO9001: 2000. The thickness of the glass unit, which is installed in the seat, is associated with the dimensions of the profile. Its depth should be more than 1.8 cm, increasing with depth. The most optimal in terms of characteristics is a double glazing.

The durability of the profile structure depends on the class of the profile wall thickness. Grade A profiles provide strong welds and a solid structure. Class B is able to provide the necessary reliability for small window units. Although class C is massively used for budget construction, its strength is low, fillet joints are thin, and the tendency to deformations and distortions reduces the service life.

Reinforcement increases the strength characteristics and the load on the profile. This is especially important for massive heavy structures. It is imperative to make sure that the profile is reinforced.

The quality of the plastic can be characterized by its appearance. It is smooth to the touch, without chips or scratches. It should have visible streaks and color uniformity. The choice of color depends on the interior of the room. Many manufacturers offer a variety of colors.

It has been empirically verified that the best in terms of price-quality ratio will be a metal-plastic system. In addition to choosing high-quality products, you need to take care of the master who will install the window unit, because 70% of successful operation depends on correct installation... An important characteristic is the seal in the profile. For Russian climatic conditions, there should be 2-3 sealing circuits, this is the only way to maintain high thermal insulation performance in severe frosts.

The rubber seal between the profile and the glass unit will last longer than polyurethane.

To maintain the temperature and humidity microclimate in the room, ventilation dampers and slots can be installed on the profile. The profile has special grooves and grooves, with the help of which the fittings are fastened with self-tapping screws. Thanks to them, the self-tapping screw does not move during installation, fixing itself in the adjacent chamber.

Since reinforcement is a prerequisite for giving strength to polyvinyl chloride, you need to check its presence during installation. A magnet will help with this. If the walls are not magnetized, then there is no metal inside.

Quality certified profile structures are marked. It can be found on the inside of the profile. The marking contains the manufacturer's name, production date and other information. The brand will help determine the authenticity of the product.

Currently, the market for PVC-based windows offers a wide range of different products. In order to attract the buyer of the company, manufacturers are developing new types of double-glazed windows, and also use various types of profiles from which the plastic window is made.

In this regard, the consumer has reasonable questions: which profile for windows to choose and what will serve as the criteria for his choice?

When choosing a profile used in the manufacture of plastic windows, it is necessary to be guided by the following criteria that determine the purpose of the window and the conditions for its operation, these are:

1. The ability to provide the required level of heat and sound insulation of the room where it is planned to install a window of this design.
2. The quality of the material used.
3. Profile class.
4. Possibility of installing double-glazed windows of various designs.
5. Geometric dimensions of the profile (width and height).
6. The presence of reinforcement.
7. Possibility of installing additional elements.
8. Operating and maintenance conditions.
9. Manufacturer's brand and reliability.
10. Cost.

In practice, a PVC profile is used, which has a different number of chambers in its design, which ensure the ability of this structural element to retain heat inside the room and maintain required level soundproofing.

Structurally, this is expressed in the division of the internal space into several air chambers by means of partitions. There can be from three to eight such chambers (air cavities), of which the most popular among household consumers are three and five chambers.

By class, PVC profiles are classified as:

• Class "A" - wall thickness from 3.0 mm.
• Class "B" - wall thickness from 2.5 to 3.0 mm.
• Class "C" - wall thickness is not standardized.

Window profile materials

In the manufacture of windows, various types of profiles can be used, both in terms of their design and the material from which they are made.

This could be:

• Wood.

It is a natural and environmentally friendly material that has always been widely used in the manufacture of windows.

Currently, due to the emergence of new technologies and the high cost of natural raw materials, it is used less widely.

Wood species such as teak, larch, oak, Canadian hemlock and teak are used for the manufacture of custom-made windows and for the construction of premium housing.

Coniferous trees are used in the manufacture of cheaper structures, but, nevertheless, they are still more expensive than products from different types plastics and some types of composites.

• Aluminum.

Pure aluminum is not a very good material in terms of its use for the manufacture of window blocks. The reason for this is its high thermal conductivity and low elasticity.

In this regard, aluminum faucet is rarely used in its pure form for these structural elements, but in combination with polyvinyl chloride materials, it is an excellent component of such products.

• Fiber composites.

Fiber composites are fiberglass made from a reinforced profile and a fiberglass composite.

This material has good thermal insulation properties and strength indicators that exceed those of wood and metal, respectively.

The disadvantage that determines its rather narrow distribution is that under the influence of the external environment (precipitation, sun rays etc.), this material is stratified.

When using a composite made on the basis of carbon fiber, this disadvantage is absent, but in this case the product is very expensive.

• Metal-plastic.

The use of aluminum, which serves as a frame in the manufacture of window profiles and plastic, made it possible to create a wonderful tandem of materials, which made it possible to combine their advantages and create a durable product with good thermal insulation properties.

It is metal-plastic profiles that are currently widely used in the manufacture of window blocks of various designs.

Choice of fittings

The choice of fittings is an important point when manufacturing and equipping a window, oddly enough it may seem at first glance. In order to do right choice, it is necessary:

• Get acquainted with the types and purpose of fittings.
• Choose the most reliable manufacturer that produces quality products (based on user reviews).
• Determine the needs of various types of fittings and their technical characteristics.
• Determine the ratio of price - product life.

The complete set and type of fittings for each specific window is individual, which is determined by its design and the method of opening the sashes (right or left, sliding or swing type, blind or swing-out design, etc.).

The standard equipment of a window made of PVC profile includes the following elements, such as:

• Window hinges (bottom and top).
• Compensator.
• Protective mechanism (fuse) against slamming.
• Devices for lifting the window sash.
• Retainers.
• Brackets.
• Swing-out mechanism.

In addition to the above products, the set may include window sash rotation limiters, slot ventilators, mosquito nets and locks that ensure the window is closed from the inside.

In the manufacture of accessories, various metals and their alloys are used, which characterizes their strength and reliability. From the outside, the fittings are coated with paint and varnish anti-corrosion materials.

The selection criteria for fittings are:

• Wear resistance.
• Resistance to external influences.
• Availability of a warranty period of operation and a certificate of conformity.
• Appearance (aesthetics) and usability.

Choosing a manufacturer of plastic windows

When the user is faced with a question related to the choice of plastic windows, in addition to the technical components that determine the characteristics of the window (the type of profile and material from which it is made, the type of glass unit, the presence and quality of seals and accessories), an organizational component appears - which manufacturer's windows to choose.

A large number of large and small companies operate on the domestic market for such products. various shapes property. Nevertheless, the main manufacturers of metal-plastic profiles are only a few companies whose products have inherent advantages and disadvantages, below are the most popular of them.

"KBE" (Kunststoffproduktion für Bau und Elektrotechnik), Germany

The KBE company operates in different countries and on different continents. On the territory of Russia there are representative offices of this company in many regions, the production of metal-plastic profiles is located in the Moscow region. The representative of the company in Russia is CJSC Profine RUS (Moscow).

The advantages of KVE products are:

• High performance in heat and sound insulation.
• Wide operating temperature range.
• The presence of a ventilation system that does not fog up double-glazed windows.

The disadvantages include:

• High price.
• White plastic can turn yellow when exposed to sunlight.

Rehau, Germany

The central office of the company for Eastern Europe is located in Moscow, and representative offices are in the cities: St. Petersburg, Voronezh, Nizhny Novgorod, Samara, Yekaterinburg, Rostov-on-Don, Novosibirsk, Krasnodar, Irkutsk, Khabarovsk and Simferopol.

The advantages of Rehau products are:

• Strength.
• A large assortment different types profile.
• Good performance in terms of heat and sound insulation.
• Frost resistance of products.

• High price.
• Limited flap height on manufactured products.

"PROPLEX", Russia

"PROPLEX" is one of the first domestic enterprises that began to work on the market of metal-plastic windows on a full cycle of their production.

The advantages of products manufactured at this enterprise are:

• Relatively low cost.
• Long service life.
• They are adapted to operating conditions on the territory of Russia.

The disadvantages are:

• There is no international quality certificate.

"VEKA AG", Germany

In Russia, the German company is represented by its subsidiary VEKA Rus, the head office and production of which are located in Moscow. In addition, representative offices of the company have been opened in a number of regions of our country.

The advantages of the "VEKA" company are:

• Wide range of models.
• High technical performance (heat and sound insulation).
• Durability.
• The use of special rubber-based seals that are not afraid of low ambient temperatures.

The main disadvantage is the high cost.

Montblanc, Russia

The Mont Blanc company has been successfully operating in the PVC market since 2000. The head office is located in Moscow, and the factories are in Elektrostal, Moscow region and Krasnoyarsk.

The advantages of products manufactured by this company are:

• Low cost.
• Adaptation of products to operating conditions in our country.
• Well done design.
• Large selection of models.
• Strength and durability of products.

The disadvantages are:

• Lack of international quality certificate.
• Low quality of the used fittings.
• Possibility of odor from the type of seal used.

What profiles are most often chosen?

The type of profile to be selected depends on the purpose of the window and its operating conditions. In addition, this is not a small important factor influencing the choice is the service life and cost of the product.

When choosing, there are always personal preferences for a particular brand, as well as the presence of representative offices of the manufacturer in the region of residence of a potential buyer. In the regions of our country, the products of various companies are popular, which is characterized by the presence of this type of production and competition between manufacturers.

For installation in residential buildings, the greatest demand is for 3 and 5-chamber metal-plastic profiles with a width of 58.0 and 70.0 mm, respectively. For northern regions, 6 and 8 chamber profiles with a width of 90.0 mm are recommended.

It is not recommended to install plastic windows in residential buildings made of a profile intended for industrial buildings and objects, about which there must be a corresponding marking on its surface (OBJECT, object, engin, tender, etc.).

In addition to the fact that when choosing a window, you need to be careful and scrupulously familiarize yourself with the type and design of the profile, glass unit and fittings, you need to take care of the high-quality installation of the purchased product. An incorrectly performed installation can negate all the advantages of a window made of a metal-plastic profile.

PVC windows are firmly in the lead deal. They differ in the highest level of heat and noise insulation, in addition, they give the possibility of choosing fittings, the method of opening the window and the color of the profile. It is also permissible to choose a double-glazed unit with the required number of cameras. However, not many people think that the window profile specifically guarantees the strength and durability of the entire system. In the note, we will put together profiles of plastic windows of various features and manufacturers.

General information about the profile of plastic windows

On average, the thickness of the profile of plastic windows varies from 58 mm to 86 mm, but some companies create a product with a width of 127 mm.

Its internal fraction is hollow, however, it is divided by bridges that create a number of light chambers. A special industrial calculation describes their dimensions and placement. The profile is not more spacious, the more it contains the number of cameras that increase the heat-saving characteristics. Another 1 feature of the profile system is the width of the filling, which describes what kind of double-glazed windows are allowed to be defined in profile. They visit one- or two-chamber type, the width of the glass in an ordinary glass unit is 4 mm (M1 brand).

Any cavity has a similar purpose:

• for water withdrawal;
• fastening fittings;
• gives an answer for strength, etc.

Profile paint has the ability to exist in a variety of ways, the coloring is applied in several ways:

• by the co-extrusion method - multilayer films create some obstacle that allows the product to endure dynamic overloads in the absence of defects;

• lamination - with imitation of the structure, for example, marbled or wood;
• monochromatic staining.

Properties of PVC profile for plastic windows

Material

• This work is made from a variation of plastic - polyvinyl chloride of snow-white colors.
• The material used is distinguished by the highest chemical stability against alkalis, solvents, acids and mineral oils.
• It is harmless to humans and the environment around them.

• Polyvinyl chloride, due to its own characteristic properties, makes it possible to manufacture frames for double-glazed windows not only of rectangular or square shape, but also in the form of arches, triangles, circles and so on. Thus, giving completely any elementary or difficult configuration to the window, allowing to embody in reality, including the most extraordinary thought of artists and architects.

Design

The internal fraction of the plastic profile body is divided by longitudinal fences, in their own order they form cavities (weightless chambers). The small number of chambers in the profile is 3, the largest is 8. The number of chambers describes the degree of thermal insulation and sound absorption of a window, rather than lighter cavities, the greater these characteristics. Immediately it should be noted that 3 and 5 chamber profiles are used with a reputation.

Reinforcement

To give rigidity, the profile is especially reinforced. The iron base guarantees the necessary strength of the system and inviolability during the operation of the window. For the reinforcement of the profile, zinc-coated steel is used, therefore it does not deform in any way during temperature drops or other actions of the environment around.

• L-shaped discharge of reinforcement - an iron insert is installed along 2 walls;
• U-shaped discharge of reinforcement, in which place the alloy increases 3 walls;
• Latent discharge of reinforcement - an iron insert is placed along 4 walls.

For window systems that have double-glazed windows with a volume of 1900 mm in height, a U-shaped reinforced profile is suitable. But, for plastic windows of huge dimensions, for example, for a terrace or balcony, a profile with a closed reinforcement is needed.

Profile class

The wall thickness of a profile describes its accessory to a specific class:

• Class A - the thickness of the profile walls must be no less than 3 mm;
• Class B - profile, where the wall thickness is from 2.5 mm;
• Class C - non-standardized wall thickness.

As a result, the width of the profile of plastic windows directly depends on its class. If it is larger, the profile is correspondingly more spacious.

• The plant surrounding Podolsk publishes a profile on German equipment in accordance with Austrian technologies.
• This product is manufactured in widths that can range from 58 mm to 127 mm, chambers from 3 to 6.
• The unique recipe makes it possible to produce a high-quality profile, differing in impact strength and special whiteness.

It is also possible to compare the properties of plastic window profiles according to the tables below.

Profiles of the German company KBE

They say that German profiles of plastic windows surpass the products of other manufacturers in terms of quality, whiteness of color, and technical features. They do not lose their own characteristics in any way, including during a long operational period, they perfectly withstand virtually all kinds of dynamic overloads and significant temperature drops (from -50 ° С to + 50 ° С).

The KBE company manufactures and supplies 2 types of more necessary profiles: KBE Ideal and KBE Specialist.

KBE Ideal - three-chamber profile

• The mounting width is 58mm;
• width of external walls - 3 mm;
• the thickness of the glass unit has the ability to compose 34 mm each;
• 3 chambers in the rim, sash, impost (horizontal and vertical crossbeams of the window);
• has the ability to be used in severe conditions (-60 ° C);
• service life - 40 years;
• the production uses environmentally friendly materials, does not contain lead.

Pros:

• with a profile width of 58 mm, it has 3 weightless chambers, their size and best condition guarantee the resistance to heat transfer. These windows have the highest degree of density, which exceeds the available GOST requirements by 5 (!) Times, as if the complete absence of dust and drafts in the room is guaranteed;
• 2 airtight gaskets guarantee good sound insulation (46 dB each). The profile is specially equipped with horizontal bridges, thereby increasing the strength of the lock when closing the window;
• Stiffening ribs are supplied in the KBE profile, which guarantee additional strength of the window system. Even more hardness is allowed by special stops, with the support of which a clear placement of the reinforcing iron insert is achieved.

KBE Specialist - five-chamber profile

• The mounting width is the same 70 mm;
• width of external walls - 3 mm;
• the thickness of the glass unit is 42 mm;
• 5 chambers in the rim and sashes, 3 or 4 in the impost (horizontal and vertical crossbeams of the window);
• Benign for use in severe conditions (-60 ° C);
• seal silhouettes suitable for class A;
• service life - 40 years;
• environmentally friendly used materials are used in the production, it does not include lead.

• a five-chamber building allows you to achieve the best sense of thermal insulation, such a profile is able to retain heat 20% more than conventional three-chamber systems. It is allowed to achieve excellent sound insulation by installing large double-glazed windows with a 70 mm profile;
• The 13 mm groove of the profile allows you to define anti-burglar fittings, thereby ensuring the safety of the building;
• kBE profile The specialist has additional horizontal jumpers, thanks to which the handles and hinges will be solidly fixed;
• with the device, the prefabricated seam comes out more spacious by about 20%, in its own order, allowing you to perform additional insulation.

Estimated price of windows from KBE profile

An important reason when choosing such or another double-glazed unit is its cost. It is often considered decisive, but Germanic window profiles highest quality can not be inexpensive in any way. Below is an approximate market price for Russia.

• On average, a single-chamber double-leaf window with volumes of 140x130 cm, in which 1 sash is of a dull look, and the other one is swing-out will deserve:

1. from a profile of 58 mm from 7500 rubles,
2. from 70 mm - from 10,000 rubles.

• The cost of a two-chamber three-leaf window with a volume of 140x203 cm, in which the 1st sash is pivoting, the central sash is of a dull look, the 3rd is swing-out, will be from:

1. from 58 mm profile 13,000 rubles;
2. from 70 mm 14500 rub. and more.

• When purchasing a balcony block with a drop-down door with a volume of 210x67 cm and a blind window - 140x136 cm, you need to pay no less:

1. from a profile of 58 mm 10500 rub.
2. from 70 mm from 12000 rubles

Where to direct your interest when choosing a plastic profile with a glass unit

In order to find what the thickness of the profile is, one must have basic knowledge about a double-glazed window, since up to 70% of heat losses occurs specifically through it.

This colorless substance consists of 2 or more glasses, which are tightly combined with the frame. A room (light strip) appears between them, filled with rarefied air or an inert gas, such as argon or krypton. This type of filling is used in the production of energy-saving insulating glass units.

A single-chamber double-glazed unit is a system of 2 glasses of 4 mm each and a weightless layer of 16 mm, in an incomplete form it is classified - 4-16-4. Thus, its mounting width is the same 24 mm. The system, the same 36 mm, comes out of a two-chamber glass unit, which consists of 3 glasses of 4 mm and 2 interlayers of 10 mm - 4-10-4-10-4.

Therefore, an appropriate profile is selected for the required glass unit. For example, optimal solution for an ordinary apartment or at home, a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed unit will serve, where a heat-reflecting coating must be applied to one glass.

If the windows go to the north side and there is a busy road nearby, then in this case the next option is suitable: a 5-chamber profile with a depth of 86 mm, replenished with a 32 mm glass unit with a protective noise-insulating film.

As soon as the balcony (gallery) is connected to the adjacent place or it is planned to make a small office (recreation room) out of it, then the profile must exist 5-chamber with an installation depth of 86 mm, and the double-glazed window is energy-saving, two-chamber with a width not to the same extent 40 mm.

For ordinary balcony insulation, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.

However, it is not easy to choose the best PVC profile and double-glazed window. It is no less important to entrust the installation of the trimmed window to experts. Otherwise, no matter how precious the system is, a bad attitude will nullify all of its highest properties.
