How to choose a profile for plastic windows. Which profile for plastic windows is better - an overview of parameters and manufacturers. Plastic windows: everything you need 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 a profit for scammers.

They entered the construction industry very firmly. Very soon, the wooden execution of windows will be a curiosity that you will not see anywhere. And there are explanations for that.

Benefits 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, accordingly, is inexpensive.

Specifications of PVC window

They are determined by the type of his profile, of which there are quite 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, then 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 with experience and who 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 well-known manufacturer of plastic windows. Well-deserved reviews, a minimum of marriage, constant training and improvement of their employees, innovative development produced designs. They cooperate with enterprises only if the latter have good equipment.

Interesting! REHAU-certified production facilities are constantly being 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 not lose color when exposed to sunlight for a long time.

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

KBE

It ranks third in our ranking after the first two companies. There are minor drawbacks: the number of marriages is slightly higher compared to previous giants, there may be delays in deliveries, they do not suit their partners with checks.

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 available in widths from 58 to 70 mm.

Trocal

The company is one of the pioneers in the production of PVC profiles. Offer a huge range for decorative possibilities.

MOTNTBLANK, PROPLESS, BRUBEBOX

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

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

When installing plastic windows, the profile plays no less a role than the double-glazed window itself. The profile is the basis of all window construction. That is why it is worth approaching his choice very 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 stand. Window profiles are the foundation for fastening the double-glazed window. That is why choose high-quality proven models.

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

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

In fact, recycled material In this case, it does not affect anything other than the price. Therefore, many professionals recommend taking exactly budget options.

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

Plastic profile for windows is divided into three main price categories:

• Economy
• Classic.
• Premium.

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

"Classic" differs from "Premium" in more, 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 service life of a metal-plastic window in any way.

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

The thickness of the plastic profile has a significant impact on the thermal conductivity and sound insulation of the product. It must be at least 3 mm. The thickness of the base of the window 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 produce profile systems with a 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 rooms, 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 fairly high price.

Also, many experts argue that a large number of air chambers negatively affects the stability of structures to external factors Sun, wind, rain. Such products may turn yellow and crack. In addition, the more chambers in the product, the softer it becomes. The design may not withstand the weight of the double-glazed window.

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 no worse than wide counterparts, but have a much lower price.

Market Review

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

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

Choosing a Profile Manufacturing Company

Choose a trusted manufacturer

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

The profiles of the KBE company are in the greatest demand in the modern market of metal-plastic structures. This German company appeared on the CIS market one of the first. 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 designs are considered one of the most durable. Their service life is 40-50 years.

Rehau profiles are 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 to their designs and a locking system that prevents entry into the house through the window. The only drawback of Rehau products is the small height of the sash.

The well-known company Veka has been losing ground a little lately. This is due to outdated design models in comparison with 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 Aluplast's designs. This manufacturer represents more than 40 decor variations. Aluplast is constantly developing various innovations in order to meet the requirements of the consumer more and more.

The disadvantage of these systems can be called their tightness. On the one hand, it 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 quite strong, but special distinguishing features from competitors do not have.

Who else is striving to market today?

A novelty in 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, in many countries, Lg products have already been evaluated as a good match between price and quality.

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

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

To GREATLY simplify your profile selection be sure to watch the video below. At least for the 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 PVC profile. Products are presented in various classes, each of which has its own characteristics. Having got acquainted with them, you will be able to choose the optimal type of window construction.

What should be a modern PVC window profile

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

It defines the following parameters for PVC products:

• class A: external walls should reach 2.8 mm in thickness, internal - 2.5 mm;
• class B: the thickness of the outer walls should not be less than 2.5 mm, the inner - 2 mm;
• class C: external and internal walls can have 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 class C products, if used, are only for installation in technical rooms or for temporary service.

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

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

Therefore, PVC windows, in the design 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.

What profile of a plastic window is better to choose? Selection tips and manufacturer rating

It is for this reason that such products are especially 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 various types of profiles, their manufacturers try to satisfy the various wishes of their customers.

Therefore, each consumer can choose the most suitable product.

Class A profile will become the best option in the following cases:

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

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 industrial facilities;

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

  For example, to achieve an increase in strength, you can use reinforcement. And the installation of a double-glazed window with several chambers 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. After weighing all the reasons in detail, you can opt for the most suitable form profile.

Which profile is best?

It all depends on the conditions of application of 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.

The data is taken from the Internet.

Everything you need to know about choosing a PVC profile

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

Most of the properties of the finished product are mainly influenced by the characteristics of the PVC profile - the basis for the design of a window or door. Why is it the profile that determines the reliability and durability of a window?

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

Width and thickness of the plastic window profile

The owner of an apartment with a window made of a wooden frame that had 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 hermetic PVC structure.

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

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

For the consumer, the advantages of a PVC window over windows with wooden frames became obvious:

1. in houses with plastic windows it became quieter and warmer;
2. there was no need to insulate and paint a wooden frame every year;
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 a plastic window - the main thing was the fact that he had it at home, then over time he began to understand installer 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 window installation company have to meet the increased requirements of consumers and are more responsible in choosing manufacturers of PVC profiles, double-glazed windows and fittings.

About PVC window profile material

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

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

We come across products from polyvinylchloride everywhere every day.

Corps household appliances, stationery, car parts, children's toys, disposable tableware, medical supplies, food packaging - all this is made of plastic. Material does not emit harmful substances, chemically stable and safe for humans. If we consider the environmental side of the issue, then PVC items that have served their time 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 window profiles.

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

PVC profile manufacturing process

PVC profile is made by extrusion. On the extruder polymer blend heated to the desired 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 segments.

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

A profile with deviations higher than those allowed by the technological regulations is sent to recycling.
Since the extrusion of window profiles is a thorough homogeneous mixing of all constituent parts recipes, 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 scope: window, balcony, door and facade.

   For each of the options, the 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 placed mainly in unheated rooms or as partitions). Profiles with six or more chambers are used in regions with severe frosty climates.

   The more chambers in a double-glazed window and profile, the higher the thermal characteristics of window blocks.

3. PVC profiles also differ from each other in 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 inside 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 depth of insulating glass is another indicator that affects the characteristics of the window.

   At the junction of the glass and the profile, a "cold bridge" is formed and heat is lost. In frosty weather, condensation may form around the perimeter of the window. In order to avoid the so-called "edge effect", profile manufacturers increase the depth of the double-glazed window to 25 mm.

6. The reinforcing element in the profile of the frame, sash and impost is the basis of their stability under the influence of wind and thermal loads on them. Each profiled part of the window must contain a metal reinforcing insert made of galvanized steel, the thickness of the rolled product and the configuration corresponding to the system requirements.
7. Important for the consumer are the aesthetic characteristics of the window. To satisfy this request of the customer of the window and door system, the PVC profile should be chosen based on its resistance to ultraviolet radiation, the possibility of choosing a color scheme.

   To prevent the window from yellowing over time, the manufacturer must add a sun protection component. Currently, in addition to color, you can choose the texture of the plastic profile, for example, 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 in shape. Arched openings can also be closed with PVC construction. Round, triangular, polygonal windows are available to fulfill the architect's intent.

How to choose PVC profile

1. First, decide on the purpose of the future product.
2. Study the climate in the area where windows or doors will be used.
3. Create an order budget.
4. Decide on the brand of the manufacturer and the supplier of the profile.

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

Narrow profile from VEKA

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

Plastic windows: everything you need to know

Many factors affect a person's mood, including beautiful view from modern window. in Vyborg the climate is not too pampering 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 Factory company, the dream of Petersburgers becomes a reality.

The narrow profile of VEKA EUROLINE differs little from the standard profile of a similar model, but in terms of its parameters, the height of the profile installed on the sash, frame and impost is significantly lower. This information can be viewed in a table.

VEKA EUROLINE profiles in comparison

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

According to the table, the mounting depth of the standard and narrow profiles have the same size, 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, a 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 all of that is great.

In order to obtain a clean, regular window and a geometric window, it is important to build a manufacturing process based on quality raw materials. In particular, high-quality PVC profiles, reliable equipment and energy-saving double-glazed windows.

Supply of PVC and its storage

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

Frame, wings, impost, glazing - all these elements of the window are brought by whips packed in six-meter pallets. To make a window out of them, they must be cut into blanks with the required length in accordance with specifications for cutting. Previously, they were stored in processor rooms equipped for this purpose.

PVC profile storage

In the future, the profile will be oriented to the production line for windows, where a new plastic window or PVC door is produced.

He saw the profile

The profile is cut at an angle of 45 degrees 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 for the window structure to be more stable and resistant to possible loads, a reinforcing steel frame is inserted into the central chamber of the profile.

This is also called a rebar profile.

Installation of the steel layer

Reinforcing (or reinforcing) PVC is a mandatory process for all types of windows that stand on a side greater than 400mm.

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

For this type of products, there is a round, round and arched image. Profile enhancement

Production of window plastic windows

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, keeping the shape and certain 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.

The most typical variant of connecting profiles is welding. Blocks are placed on welding machine in the required sequence, their edges are heated to melting point and pressed together.

profiles of the compound angle between welding power not only turn out to be worse than the strength of the corresponding profile, but also more (as in tests carried out in experimental laboratories).

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

Discs and sawing exercises (cleaning) are configured to remove excess plastic and do not touch the underlying structure. After this step, the window frame and wing are prepared for the next procedure - the installation of 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 without which the window cannot be moved - and there is additional equipment.

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

Which profile is better for modern plastic windows?

In order for each element to window frame matched the frame lock - all these processes are carried out in accordance with pre-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 that is missing until it is fully prepared is the clear glass, which 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 double-glazed window.

A double glazed block, 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 from different glasses, and filling the gap between the glasses can also be different. In the warmest (energy efficient) inert gas double glazing models, argon is induced in the cavity between the glass plates. It is heavier than air, so in winter it is better to prevent freezing and hot summer sun in summer.

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

Now the design (window or door block) should be validated 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 off, the functionality is in the order of the state - this window is suitable for shipping to the customer and complaints are unlikely.

How to distinguish a high-quality window from 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 do not differ much from each other, but the difference is hidden in the structure of the structure and the material of manufacture.

Peculiarities

The design of the window includes 3 parts - a profile, glass and fittings. The window profile is a stable support that holds the double-glazed window. From it, frames and window sashes are made, which carry the load of the entire structure.

The profile has the following characteristics:

• 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 correspond to the coefficient of thermal linear expansion of the glass. It is 0.000009 m/m°C. The difference in the expansion of the profile and glass should be minimal so that there is no tensile stress on the materials. This leads to premature wear of the seal.
• High modulus of elasticity. Different weather conditions can lead to deformation of the structure. The higher the elasticity of the profile, the greater the stress force the material can withstand.

Profile structures are made of various structures. Profiles can be solid and hollow. Full-bodied are made from an array of material, usually wood. The hollow structures are separated from each other by partitions, forming chambers. Jumpers 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 camera adjacent to the room is intended for installation window fittings. Each chamber, filled with air or other heat-insulating material, performs heat-insulating functions.

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

Kinds

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 types of trees are a classic proven material for the manufacture of window frames. For the assembly of profiles, glued laminated timber is taken from cedar, pine, larch, oak, alder. The tree meets all the requirements for a window profile. The thermal conductivity coefficient averages 0.2 W / m * K, the modulus of elasticity is 9-10 GPa. When heated, it does not expand, but under the influence high temperatures capable of catching 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;
• the tree does not attract dust, as there is no electrostatics;
• aesthetic appeal;
• structural strength determines the density of the tree - 0.5-0.6 t / m3;
• the ability to repair defects on the surface;
• depending on the type of wood, the service life is from 30 to 90 years.

Wooden structures hold 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 flame retardant primers leads to higher prices 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 leads to the appearance of spots on the tree.

Aluminum profiles are light and strong, consist of two or three chambers. The main advantage when using them is fire safety. A 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 thermal insert made of polyamide is included in the design of aluminum profiles, which leads to the massiveness and increase in the cost of the product. The high coefficient of elasticity (up to 70 GPa) makes it possible to use it for glazing commercial premises, public buildings, and balconies.

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

The fiberglass profile has not received wide distribution due to the high cost. It is a third higher than the 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 solid arched elements.

Polyvinyl chloride profile structures can be completely made of polyvinyl chloride or reinforced with a metal insert. Often profiles with reinforcement are called metal-plastic. For insertion, 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 insert where two or three walls are reinforced. For a massive window, a metal insert of a closed loop is installed. There is no reinforcement for profiles smaller than 60-70 cm.

PVC profiles have the following technical characteristics:

• Low thermal conductivity of 0.15-0.16 W / m * K allows you to be a leader among all materials.
• Density is more than 2 times higher than wood - 1.4 t/m3.
• The high coefficient of linear expansion 60-70 10-6 m/m*C and the low elasticity modulus of 2.8 GPa are compensated by profile reinforcement.
• Chemical resistance to alkalis and fats. Relative resistance to solvents and acids.
• The number of chambers is from 3 to 8. Chambering affects the heat-insulating and noise-absorbing qualities, strength and rigidity of the structure.
• The width of the filling determines the type of double-glazed window to be installed. The depth of the seat from 15 mm inside allows you not to fog up and not 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.

PVC profile can be painted in different colors. Standardly there is a monochromatic 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 applying a colored film by the co-extrusion method.

According to GOST 30674-99, for window blocks made of PVC profiles, the thickness of the inner and outer walls varies by class:

• Class A with outer walls - more than 2.8 mm, the thickness of the 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 C does not have strict standards for the thickness of the case.

The outer walls form the body of the profile, they are visible from the side of the room and the street. One inner wall adjoins the mounting wall, the other is located inside the structure and serves as a stand for the double-glazed window.

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 condensate on double-glazed windows.

Frequent airing of the room will help to remove the disadvantage, 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.

stand out following sizes profile:

• 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 - an energy-saving profile with 5-6 chambers and the ability to install a double-glazed window up to 5 cm.

In a three-chamber profile, the width is 58-60 mm. More cameras require a frame thickness of more than 70mm. With a narrow profile, the size of the installed double-glazed window 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 larger.

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 pick up a wooden profile. Modern fiberglass and aluminum windows suitable for progressive interior design. An acceptable solution may be a PVC profile system.

The selection is made according to the following criteria:

• Profile size. It is characterized by the installation width and is determined by the installation site and operating conditions.
• available budget.
• number of cameras.
• Products have a certificate.
• Depth and width of the double-glazed window seat, profile class.
• The presence of reinforcement.
• Appearance and color.

The most important indicator for maintaining heat in the house is the width of the profile.

It depends on the atmospheric conditions of the local climate. In the southern regions, you can install a narrow profile with a depth of 58-60 mm. 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 consider 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 profile of 70 mm is installed. For public and commercial buildings, a profile with a depth of 58-70 mm is suitable. 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 profile brands 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;
• elite.

Economy class profile structures are the most budgetary with low quality and thermal insulation characteristics, a width of not more than 58 mm and a wall thickness of class B or C. The Standard class complies with GOST and European standards, three-chamber, with a width of 58-60 mm. The best solution for quality and price.

Elite profiles with an installation depth of 70-80 mm allow marking 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 a double-glazed window up to 5 cm. The number of chambers corresponds to the width of the profile. A 58mm profile cannot contain more than three cameras. Depth of 70 mm allows to accommodate from 3 to 5 air chambers. The 90 mm profile has 6-7 chambers. The same width of the profile, containing a different number of chambers, slightly affects the thermal insulation characteristics of the entire block.

Quality window profiles are RAL certified. A certified product is a guarantee of long-term operation and compliance with all manufacturing cycles. The factories where the products are manufactured also receive the ISO9001:2000 quality management certificate. The thickness of the insulating 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, it increases with increasing depth. The most optimal in terms of characteristics is a double-glazed window.

The durability of the profile structure depends on the wall thickness class of the profile. Class 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 widely used for budget construction, its strength is small, the corner connecting seams are thin, and the tendency to deformation and distortion reduces the service life.

Reinforcement increases the strength characteristics and load on the profile. This is especially important for a massive heavy structure. Be sure to make sure that the profile is reinforced.

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

It has been experimentally verified that the metal-plastic system will be the best in terms of price-quality ratio. 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 during severe frosts.

The rubber seal between the profile and the double-glazed window will last longer than polyurethane.

To maintain the temperature and humidity microclimate in the room, ventilation flaps and slots can be installed on the profile. Special grooves and recesses are laid in the profile, 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, being fixed in the adjacent chamber.

Because reinforcement is required condition to give 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.

High-quality certified profile structures are marked. It can be found on the inside of the profile. The marking contains the name of the manufacturer, production date and other information. The stamp will help determine the authenticity of the product.

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

In this regard, the consumer has reasonable questions: what 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 its operating conditions, 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 installation of double-glazed windows of various design.
5. Geometric dimensions of the profile (width and height).
6. The presence of reinforcement.
7. Possibility to install additional elements.
8. Terms of use and care.
9. Manufacturer's brand and its reliability.
10. Price.

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 its design and the material from which it is made.

It could be:

• Tree.

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 wood are used to make windows according to individual orders and in 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 various kinds plastics and some types of composites.

• Aluminum.

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

In this regard, aluminum crane 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 glass-reinforced plastics made on the basis of a reinforced profile and a fiberglass composite.

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

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

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.

Hardware selection

The choice of fittings is an important point in the manufacture and equipment of the window, no matter how strange it may seem at first glance. To make right choice, necessary:

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

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

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

• Window hinges (lower and upper).
• Compensator.
• Protective mechanism (fuse) against slamming.
• Window sash lifters.
• Fasteners.
• Brackets.
• Tilt and turn mechanism.

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

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

The selection criteria for fittings are:

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

Choosing a manufacturer of plastic windows

When the user faces 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 the material from which it is made, the type of double-glazed window, the presence and quality of seals and fittings), there is also an organizational component - which window manufacturer to choose.

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

KBE (Kunststoffproduktion für Bau und Elektrotechnik), Germany

The company "KVE" works 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 KBE products are:

• They are adapted to the operating conditions in Russia.

The disadvantages are:

• There is no international quality certificate.

VEKA AG, Germany

In Russia, the German company is represented by its subsidiary, a subsidiary of VEKA Rus, headquartered and manufactured in Moscow. In addition, representative offices of the company have been opened in a number of regions of our country.

The advantages of VEKA products 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.

What profiles are most often chosen?

The type of selected profile depends on the purpose of the window and its operating conditions. In addition to this, an 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 where the potential buyer lives. 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, 3- and 5-chamber metal-plastic profiles with a width of 58.0 and 70.0 mm, respectively, are in greatest demand. For the 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 the appropriate marking must be present on its surface (OBJECT, object, engine, 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, double-glazed windows and fittings, you need to take care of the quality installation of the purchased product. An incorrectly performed installation can cross out all the advantages of a window made of a metal-plastic profile.

Plastic windows firmly occupy the leading deal. They differ in the highest level of heat and noise insulation, besides, they give the possibility of choosing fittings, the method of opening the window and the color of the profile. It is also possible to choose a double-glazed window with the required number of cameras. However, not many people think that a particular window profile guarantees the strength and durability of the entire system. In the note, we will compare the profiles of plastic windows that are different in features and manufacturers.

General information about the profile of plastic windows

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

Its internal fraction is hollow, but separated by bridges, creating a number of light chambers. A special industrial calculation describes their dimensions and placement. The more spacious the profile, the more it contains the number of chambers that increase heat-preserving characteristics. Another feature of the profile system is the width of the filling, which describes which type of double-glazed windows is allowed to be defined in the profile. They visit one- or two-chamber type, the width of the glass in a conventional double-glazed window is 4 mm (M1 brand).

Any cavity owns a close appointment:

• for the withdrawal of water;
• fastening accessories;
• gives an answer for strength, etc.

Profile paint has the ability to be diverse, the colors are applied in several ways:

• 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 coloring.

PVC profile properties for plastic windows

Material

• This work is made from a variation of plastic - snow-white polyvinyl chloride.
• The material used is characterized by the highest chemical resistance to alkalis, solvents, acids and mineral oils.
• It is harmless to humans and the surrounding environment.

• Polyvinyl chloride, due to its characteristic properties, makes it possible to manufacture frames for double-glazed windows not only in a 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 translate into reality, including the most extraordinary idea of ​​artists and architects.

Design

The internal fraction of the plastic case of the profile is divided by longitudinal barriers, 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 the window, rather than lighter cavities, the greater these characteristics. It should be noted right off the bat that 3- and 5-chamber profiles are used by reputation.

Reinforcement

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

• L-shaped reinforcement discharge - an iron insert is installed along 2 walls;
• U-shaped discharge of reinforcement, in which place the alloy increases 3 walls;
• Hidden 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, you need a profile with closed reinforcement.

Profile class

The profile wall thickness 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, in which place 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. The larger it is, the correspondingly more spacious profile.

Comparison of plastic window profile manufacturers

Profiles of the German company KBE

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

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

KBE Ideal - three-chamber profile

• Mounting width is 58 mm;
• width of external walls - 3 mm;
• the thickness of the double-glazed window has the ability to compose 34 mm;
• 3 chambers in the rim, sashes, impost (horizontal and vertical window bars);
• has the ability to be used in formidable conditions (-60 ° C);
• service life - 40 years;
• the production uses environmentally friendly used materials, does not contain lead.

Pros:

• with a profile width of 58 mm, it has 3 weightless chambers, their size and best condition guarantee resistance to heat transfer. These windows have the highest degree of density, which exceeds the existing GOST requests by 5 (!) Times, as if the complete absence of dust and drafts in the room guarantees;
• 2 sealed gaskets guarantee good sound insulation (46 dB each). The profile is specially equipped with horizontal lintels, thereby increasing the strength of the lock when the window is closed;
• In the KBE profile, stiffening ribs are supplied, which guarantee additional strength of the window system. Another increase in 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

• Mounting width is the same 70 mm;
• width of external walls - 3 mm;
• the thickness of the double-glazed window is 42 mm;
• 5 chambers in the rim and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
• Good quality for use in severe conditions (-60°C);
• seal silhouettes fit class A;
• service life - 40 years;
• the production uses environmentally friendly used materials, does not cover lead in any way.

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

Approximate price of windows made of KBE profile

An important reason when choosing this or that double-glazed window is its cost. Often it is considered decisive, however, German window profiles of the highest quality can never be cheap. Below is the approximate market price in Russia.

• On average, a single-chamber double-leaf window with volumes of 140x130 cm, in which 1 sash is deaf and the other is tilt-and-turn, 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 rotary, the central sash is of a dull appearance, the 3rd is tilt-and-turn, 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 at least:

1. from profile 58 mm 10500 r.
2. from 70 mm from 12000 rubles

What to focus on when choosing a plastic profile with a double-glazed window

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

This colorless substance consists of 2 or more glasses, which are hermetically combined with the frame. A room (a light strip) appears between them, overflowing with rarefied air or an inert gas, such as argon or krypton. This family of filling is used in the production of energy-saving double-glazed windows.

A single-chamber double-glazed window 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 same 36 mm system comes out of a double-glazed window, which consists of 3 glasses of 4 mm each and 2 layers of 10 mm each - 4-10-4-10-4.

Therefore, an appropriate profile is selected for the required double-glazed window. For example, optimal solution For ordinary apartment or at home, a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed window will serve, where a heat-reflecting coating should 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 following option is suitable: a 5-chamber profile with a depth of 86 mm, replenished with a 32 mm double-glazed window 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 (rest room) out of it, then the profile must be 5-chamber with an installation depth of 86 mm, and the double-glazed window must be energy-saving, two-chamber with a width not less than 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 enough to simply choose the best PVC profile and double-glazed window. It is no less important to entrust the installation of a finished window to experts. Otherwise, however precious the system may be, a bad attitude will nullify all its highest properties.
