Ranking first in the Southeast region and third in the world in terms of polymer production, the chemical concern (South Korea) has an industry-leading research and development center, where the best chemists - technologists from around the world are gathered. The long-term work of this division has been embodied in a recipe that is balanced in all respects, which maximally corresponds to the harsh Russian conditions, in many respects exceeding the requirements of GOST.
Of course, at the own production of one of the world's largest chemical concerns, there are no procurement, transport, storage, customs, salary costs for the entire staff related to raw materials, which does not increase the cost of the profile and, of course, there are no interruptions in the raw materials and fillers themselves, and means loss as a profile.
LG Hausys, as a guru of the PVC industry, was in no hurry to enter the Russian market, but, realizing all the responsibility for its performance, for 10 years watched how European colleagues, with traditional Teutonic tenacity, made bumps on the Russian expanses.
Such prudence, traditional for the Asian mentality, has degenerated into a comprehensive program for the development of the Russian market, namely:
Plastic profile LG Hausys L-600 specially designed to meet consumer demand for high-quality plastic windows with excellent durability, heat saving and reasonable prices. The L-600 plastic profile system provides increased thermal insulation and complete absence of noise thanks to a 4-chamber structure with a construction depth of 60 mm, created using LG Hausys technologies in accordance with the highest requirements.
Plastic profile LG Hausys L-700 with unique indicators of heat saving and sound insulation, it is able to satisfy the highest requirements of the most demanding customers. Plastic windows from the L-700 profile can be used in areas with the most severe climatic conditions. The design of the plastic 5-chamber L-700 profile with a construction depth of 70 mm, thought out to the smallest detail, transforms any plastic windows into an ultra-modern finished look.
LG Hausys L-600 system - door. Especially for the manufacture of plastic entrance doors, the L-600 system has been developed - a door system. Due to the increased strength of welded joints in LG Hausys profiles and the use of well-proven additional inserts that provide a second (additional) welding circuit, a technical solution with a large margin of safety is obtained. Plastic doors LG Hausys L-600 - the best solution for use in residential and office buildings.
All profile systems are specially adapted for increased thermal insulation.
Based on many years of experience in the production of PVC profiles for Canada and the northern regions of the United States (including Alaska), LG Hausys made a fundamental decision to bring systems with enhanced thermal insulation properties to the Russian market.
For example, no system even provides for the possibility of using a cold bay window and corner connection. Additional and stand profiles have a three- or four-chamber section. And even the overlay for the steel strip has chambers around the perimeter in its section!
Fundamental refusal to reduce the cost of systems by reducing the wall thickness.
LG Hausys fundamentally does not follow the beaten path, which, unfortunately, is characteristic of many well-known European manufacturers. Reducing the thickness of the outer walls by 5-10 percent is, on the one hand, a generally accepted method for reducing product prices, while not contradicting the requirements of GOST, but, on the other hand, significantly worsens the overall strength, static and thermal performance of the finished window. This path is unacceptable for LG Hausys, which does not seek compromises in terms of quality.
The general principle of the company is to supply a high quality product at competitive prices!
When developing the design and designing the profile, computer simulation data and laboratory research results were taken into account. The profile structure has 4 air chambers, and the thickness of the outer wall is at least 3mm, which ensures minimal heat loss. The diagram obtained on the basis of experimental data clearly confirms the high thermal insulation properties of the L-600 series profile.
Thanks to the 20-degree bevel of the outer panel of the L-600 profile and the total width of the frame and sash in the finished product, equal to 114 mm, the glazing area has been increased. As a result, plastic windows from the LG Hausys profile of this series let in more light, increasing visibility and meeting modern design requirements.
Surface treatment by special methods makes it possible to achieve a special degree of gloss, which in turn has a positive effect on the appearance of the euro-window, reducing the degree of contamination of the profile due to the deposition of natural dust on it. Which is especially important due to its quantity, characteristic of our urban conditions.
The results of sanitary and epidemiological tests of the LG Hausys profile confirm the right to install window products, both in residential and industrial premises. With the help of plastic windows from the LG Hausys profile, it is possible to glaze preschool and educational institutions, medical and medical facilities, industrial and domestic facilities.
Since 2001, in Russia, the requirements for PVC window profiles have been regulated GOST 30673-99 “polyvinyl chloride profiles for window and door blocks. Specifications".
Qualitative characteristics of LG Hausys profiles fully meet the requirements of this GOST, which is confirmed by certificates for the LG Hausys profile. There is an opinion that PVC and products based on it pose a danger to the environment and human health. The main complaints are made about the presence of chlorine and lead compounds in the polymer (when used in the production of lead stabilizers).
Objectively, the presence of any chemical element in the composition of a complex compound is not a basis for concluding that it is environmentally hazardous or safe. For example, chlorine, which is the most toxic gas in its free state, is the main component in the composition of ordinary table salt (NaCl). As for lead compounds, they are securely closed in the polymer structure.
FOUR-CHAMBER PROFILE SYSTEM SERIES PLUS 60
WITH A SMALLER (REDUCED) HEIGHT OF THE FRAME (WINDOW FRAME) AND LEAF AND, ACCORDINGLY, INCREASED LIGHT OPENING (AREA OF THE LIGHT-TRANSPARENT PART)!
Lead-stabilized plastic pipes for drinking water have been in operation in Germany for over 40 years and have not been shown to adversely affect human health. We all use PVC kettles in everyday life, we drink boiling water from them every day, and we don’t lick or bite plastic windows even when they are cold.
The modern technology for the production of profiles used by LG Hausys eliminates the emission of toxic and poisonous substances and harm to the health of production personnel, since the processes of mixing, melting and molding take place in hermetically sealed cases, the components of the raw materials go into production and are loaded packaged in special packaging.
Published research data from the Vienna University of Economics show that the production of PVC window profiles is less energy-intensive and less polluting than the production of similar profiles from other materials.
Products from the LG Hausys profile can be installed up to 100 meters above the ground, as the existing system of various reinforcing profiles allows them to withstand the highest wind loads.
Why plastic windows from LG Hausys profiles are an interesting offer on the Russian market:
- The profiles are powerful, with a large wall thickness, without the harmful savings inherent in many profiles of domestic production;
- Profiles have an excellent uniform bright white color and high-quality glossy surface, pleasant to the touch;
- Profiles are characterized by high plasticity, high impact strength, i.e., unlike analogues, they do not crack;
- For the extrusion of profiles, LG Hausys uses only virgin PVC of its own production, without the use of recycled materials;
- The L-600 profile, with the dimensions and price of standard domestic profiles (such as KBE, Veka, Rehau, Proplex, etc.), has 4 air chambers, which determines better thermal insulation performance than 3-chamber analogues;
- The price of windows from LG Hausys profiles is not higher than the prices of windows of the lower price segment from domestic profiles. At the same time, the characteristics and consumer qualities of such products are much better. This pricing policy is determined by the desire of the LG concern to occupy a significant share of the Russian market.
Profile plastic windows LG Hausys offered by our company Eurostyle- today is really the most profitable option in terms of "PRICE / QUALITY" ratio! Now you can also decorate your life with comfortable and modern euro-windows from the profile.
1. Plastic windows and doors made from LG Hausys profile systems are the warmest on the market of translucent structures:
A specific function of a window, unlike other enclosing elements of building structures, is to provide light transmission. This forces the use of appropriate materials in its design, the task of which, first of all, is successful light transmission. But at the same time, thermophysical characteristics are significantly reduced, in comparison with other enclosing elements of the building.
Through the windows, which usually do not occupy the largest part of the building envelope, up to 50% of all the heat that the building loses leaves. Therefore, one of the main requirements for windows is their ability to retain heat inside the room. This ability characterizes, in accordance with GOST RF, the reduced resistance to heat transfer.
The reduced heat transfer resistance for the main profiles of the 4-chamber L-600 system, which has a system depth of 60 mm, is at least 0.74 m2 x deg C / W, which significantly exceeds the performance of all similar systems from other profile manufacturers and corresponds in value to 5 -ti chamber systems with a system depth of 70mm.
The main profiles of the 5-chamber 70mm L-700 system have a reduced heat transfer resistance value of 0.91 m2 x deg C / W and generally have no analogues among similar products from competitors.
(Attention! The values of the reduced heat transfer resistance are given taking into account the installed steel reinforcement!).
2. Plastic windows and doors made from LG Hausys profile systems are the most reliable in terms of mechanical characteristics:
In the process of manufacturing, delivery, installation and operation, plastic windows withstand significant mechanical stress. And on how successfully the profile withstands these loads, ultimately depends on the successful operation of window structures. An important indicator of such properties is Charpy impact strength.
The Charpy impact strength for the LG Hausys profile is 50 kJm2, which is more than 3 times higher than the requirements of GOST RF (15 kJm2). Thus, plastic windows from this profile have a high safety margin of mechanical properties.
3. Plastic windows and doors made from LG Hausys profile systems work equally well in the widest temperature range, from the lowest to the highest:
An important requirement for plastic windows and doors is their ability to function successfully during the summer heat at high (+30 - +45 degrees C) temperatures. An indicator of this ability is the Vicat softening temperature. The higher this indicator, the less the mechanical properties of the profile change in the range of +30 - +45 degrees C compared to its properties at +15 - +20 degrees C.
The Vicat softening temperature for LG systems is 91 degrees C, which significantly exceeds the requirements of GOST RF (75 degrees C) and RAL (81 degrees C), as well as the corresponding indicators of similar competitive systems. This characteristic indicates that plastic windows and doors made from the LG Hausys profile practically do not lose their mechanical properties even at temperatures of +40 - +50 degrees C. This allows them to be successfully operated without any problems in any summer heat.
At low temperatures, the main problem is associated with a decrease in the plasticity of the profile, which can lead to mechanical damage to window structures during their operation in such conditions. The verification of these profile properties is a test for resistance to impact at a negative temperature, carried out in accordance with GOST RF and RAL.
When testing for resistance to impact at a negative temperature, not a single destruction of the test samples was revealed. And this despite the fact that the requirements of GOST RF and RAL allow the destruction of one out of ten tested samples.
Thus, we see that plastic windows and doors made from LG Hausys profile systems work equally well in the widest temperature range, from the lowest to the highest.
4. High rates of weldability. Plastic windows and doors made from LG Hausys profile systems are reliable during installation. Manufacturability:
The greatest load during the installation of plastic windows and doors falls on the welded corner joints of the box. Therefore, this structural element is checked especially carefully. There is a special method for checking the reliability of welded joints.
The tests carried out by us during certification in the subdivisions of the Gosstroy of the Russian Federation showed that the margin of safety of the welded joints of the box is more than 2.5 times compared with the requirements of GOST. Thus, plastic windows from LG Hausys profile systems do not have problems with the destruction of the weld during installation.
In addition, the good weldability of the profile allows, without compromising the quality of the welded joint, to clean it at automatic cleaning stations, where the cooling time after welding is less than on conventional production lines. Those. The LG Hausys profile is the best match for today's most advanced processing methods.
5. The durability of LG profile systems significantly exceeds the requirements of GOST. In all respects, the LG Hausys profile can successfully work even after the required 40 conditional years of operation:
When a client chooses plastic windows and doors, durability is the most important requirement. What basic properties can change in a profile during its long-term operation? These are, first of all, mechanical properties and color change.
Naturally, over time, the mechanical properties of the profile decrease and the color gradually changes. How long these parameters remain within the acceptable range determines the durability of the profile.
Consider the mechanical properties. In accordance with GOST 30673-99, the tensile strength of the profile after 40 years of conditional operation can change from the control parameters by 40%. The corresponding change in LG profiles is 9.8%. The allowable change in Charpy impact strength is 50%, and for the LG test specimens it is 14.2%.
The allowable color change after 40 years of conditional operation is 3 steps on the gray scale threshold, and for LG profiles this parameter is 2.
Thus, we see that even after 40 years of conditional operation, the profiles retain a large margin both in terms of mechanical properties and color. This allows our structures to work successfully for a long time even after the stipulated 40 conditional years of operation.
6. High accuracy of the geometric parameters of the profile is the key to the successful operation of window systems:
An important parameter for the profile is also the accuracy of the geometric dimensions of the profiles. Since plastic windows consist of many elements that match in a large number of sizes and surfaces, the accuracy of manufacturing the profiles themselves is the most important condition for creating a high-quality window unit.
The determining factors here are the recipe, which we will discuss below, the quality of the extrusion equipment and the experience of the personnel providing the extrusion process.
LG Hausys has been producing window profiles of a modern type for 30 years, having accumulated vast experience in this area. Naturally, the personnel involved in production also have extensive experience and qualifications.
The large production volume (more than 190 lines) and the widest range of products used in completely different markets also contribute to the accumulation of experience. At the same time, our equipment suppliers are European companies Weber (extruders) and Greiner (dies) - leaders in the market of extrusion equipment.
The combination of the above reasons makes it possible to ensure the accuracy of extrusion of LG window profiles with tolerances that are an order of magnitude more accurate than the requirements of GOST RF. Where GOST requires a tolerance within 1mm, our tolerances do not exceed 0.1mm, and often they are even lower.
7. Reasons that allow LG Hausys to produce PVC profile with unique technical characteristics:
What is the reason for the unique technical characteristics of LG profile systems? We note right away that all the above properties of the profile are primarily related to the recipe that our profiles have. Here LG Hausys has the potential to be incomparably greater than that of our competitors.
The quality indicators of the profile are highly dependent on the so-called additives, or additives. It is they that give it the specified physical and chemical properties (strength, plasticity, color stability). If the technological production cycle is disturbed, the chemical composition of the mixture changes, or an increased content of recycled PVC is used, the quality of the profile suffers greatly (over time, plastic windows turn yellow, freeze and deform in winter). Therefore, when choosing a window, the guarantees and reputation of the manufacturer are so important.
LG Hausys is one of the largest PVC manufacturers in the world. At the same time, we, of course, use raw materials of our own production in our profile systems, selecting the most optimal PVC brands for profile systems, taking into account the requirements of those regions where plastic windows from our profile will then work. The same goes for additives, most of which we also produce ourselves. Having experience in the creation and production of not only profiles, but also the raw materials for its production, independently creating the product during the full production cycle, we can really give PVC window profiles the properties that are optimal for this product. If necessary, it is possible to quickly make the necessary changes both in the design and formulation of window profiles, as well as quickly create new products required by our customers.
These are our profile capabilities, which our competitors do not have, and determine the uniqueness of the technical properties of the magnificent window profile from which plastic windows are made for you by our Eurostyle company!
The South Korean company LG Chem is the parent company of the world famous concern LG. By the way, LG Chem is not only windows! The company operates in several directions and produces chemicals, electrical goods, manufactured goods, polymers and other products. Today, it employs more than 10,000 people, and its products are sold in many countries: in Japan, Turkey, the USA, China and India. Literally 5 years ago, LG Chem products appeared in Russia.
And speaking of windows...
One of the directions of the company is the production of PVC window profiles. The assortment is represented by two types of profiles: windows LG Chem L-600 and LG Chem L-700. They differ in the depth of the PVC profile, which in the first version is 60 cm, and in the second - 70 cm.
All LG Chem profiles are made from quality materials that have been developed based on the company's own research. LG Chem Ltd has its own research and development center, which is engaged in the introduction of modern technologies and constantly improves the competitiveness of products. As a result, LG Chem windows are undemanding in operation and are suitable for installation in any regions of Russia. They perfectly tolerate both extreme heat and frost. Despite the fact that the windows were developed in sunny Korea, they are ideal for our harsh climatic conditions.
Advantages of the LG Chem window:
- The climate of Russia is usually called "harsh", and not every window will endure the test of Russian frosts and winds. LG Chem windows are perfect for both the southern and northern regions of our country. They are not afraid of sudden temperature changes that occur in some of them.
- LG Chem windows can be equipped with anti-burglar fittings and. In combination with a special profile design, it makes the window truly impregnable. All LG Chem profiles have a fitting eurogroove, the presence of which makes them compatible with fittings from most manufacturers.
- Thanks to the four- and five-chamber profile, LG Chem windows perfectly retain heat in the room. In addition, with such windows you will forget what a draft is!
- With PVC windows LG Chem in the house or office will become even cleaner. After all, LG Chem windows do not let dust and dirt into the room.
- Of course, the windows of LG Chem "protect the ears of the owners" from street noise. Now the sounds of your hometown will not bother you during the day, but at night.
- The fold straightener, located horizontally, reduces the time for the selection and installation of the lining under the double-glazed window. Due to the fact that the lining of the simplest form is suitable for LG Chem windows, it turns out to save a little on its cost.
- The outer part of the LG Chem profile has a 20-degree slope. Thanks to this structure, drops of moisture do not linger on it - rainwater does not penetrate inside, due to which its service life is significantly increased.
And that is not all!
As you can see, LG Chem profiles have a lot of advantages. But, most importantly, that's not all!
LG Chem profiles can be painted in any shade you like. Love classic white? - You are welcome. LG Chem windows in classic white design are very beautiful. Or maybe you want the color of your windows to resemble the texture of natural wood? - There is nothing easier. Laminated windows LG Chem outwardly practically do not differ from natural wooden ones. Red, pink, yellow or, for example, lilac - you can choose the shade of the window that best fits into your interior.
LG Chem windows are very good. But we have not named their main advantage. And we are talking about low cost. Low price + high quality + excellent consumer properties. Does a good window need anything else?
Almost 40 years of experience, strict quality control and continuous improvement of its products - all this speaks in favor of LG Chem. Choose windows from a global manufacturer, and you won't regret it!

The reduced heat transfer resistance for the main profiles of the 4-chamber L-600 system, which has a system depth of 60 mm, is at least 0.74 m2 x deg C / W, which significantly exceeds the performance of all similar systems from other profile manufacturers and corresponds in value to 5 -ti chamber systems with a system depth of 70mm.
The main profiles of the 5-chamber 70mm L-700 system have a reduced heat transfer resistance value of 0.91 m2 x deg C / W and generally have no analogues among similar products from competitors.
(Attention! The values of the reduced heat transfer resistance are given taking into account the installed steel reinforcement!).
2. Plastic windows and doors made from LG Hausys profile systems are the most reliable in terms of mechanical characteristics:
In the process of manufacturing, delivery, installation and operation, plastic windows withstand significant mechanical stress. And on how successfully the profile withstands these loads, ultimately depends on the successful operation of window structures. An important indicator of such properties is Charpy impact strength.
The Charpy impact strength for the LG Hausys profile is 50 kJm2, which is more than 3 times higher than the requirements of GOST RF (15 kJm2). Thus, plastic windows from this profile have a high safety margin of mechanical properties.
3. Plastic windows and doors made from LG Hausys profile systems work equally well in the widest temperature range, from the lowest to the highest:
An important requirement for plastic windows and doors is their ability to function successfully during the summer heat at high (+30 - +45 degrees C) temperatures. An indicator of this ability is the Vicat softening temperature. The higher this indicator, the less the mechanical properties of the profile change in the range of +30 - +45 degrees C compared to its properties at +15 - +20 degrees C.
The Vicat softening temperature for LG systems is 91 degrees C, which significantly exceeds the requirements of GOST RF (75 degrees C) and RAL (81 degrees C), as well as the corresponding indicators of similar competitive systems. This characteristic indicates that plastic windows and doors made from the LG Hausys profile practically do not lose their mechanical properties even at temperatures of +40 - +50 degrees C. This allows them to be successfully operated without any problems in any summer heat.
At low temperatures, the main problem is associated with a decrease in the plasticity of the profile, which can lead to mechanical damage to window structures during their operation in such conditions. The verification of these profile properties is a test for resistance to impact at a negative temperature, carried out in accordance with GOST RF and RAL.
When testing for resistance to impact at a negative temperature, not a single destruction of the test samples was revealed. And this despite the fact that the requirements of GOST RF and RAL allow the destruction of one out of ten tested samples.
Thus, we see that plastic windows and doors made from LG Hausys profile systems work equally well in the widest temperature range, from the lowest to the highest.
4. High rates of weldability. Plastic windows and doors made from LG Hausys profile systems are reliable during installation. Manufacturability:
The greatest load during the installation of plastic windows and doors falls on the welded corner joints of the box. Therefore, this structural element is checked especially carefully. There is a special method for checking the reliability of welded joints.
The tests carried out by us during certification in the subdivisions of the Gosstroy of the Russian Federation showed that the margin of safety of the welded joints of the box is more than 2.5 times compared with the requirements of GOST. Thus, plastic windows from LG Hausys profile systems do not have problems with the destruction of the weld during installation.
In addition, the good weldability of the profile allows, without compromising the quality of the welded joint, to clean it at automatic cleaning stations, where the cooling time after welding is less than on conventional production lines. Those. The LG Hausys profile is the best match for today's most advanced processing methods.
5. The durability of LG profile systems significantly exceeds the requirements of GOST. In all respects, the LG Hausys profile can successfully work even after the required 40 conditional years of operation:
When a client chooses plastic windows and doors, durability is the most important requirement. What basic properties can change in a profile during its long-term operation? These are, first of all, mechanical properties and color change.
Naturally, over time, the mechanical properties of the profile decrease and the color gradually changes. How long these parameters remain within the acceptable range determines the durability of the profile.
Consider the mechanical properties. In accordance with GOST 30673-99, the tensile strength of the profile after 40 years of conditional operation can change from the control parameters by 40%. The corresponding change in LG profiles is 9.8%. The allowable change in Charpy impact strength is 50%, and for the LG test specimens it is 14.2%.
The allowable color change after 40 years of conditional operation is 3 steps on the gray scale threshold, and for LG profiles this parameter is 2.
Thus, we see that even after 40 years of conditional operation, the profiles retain a large margin both in terms of mechanical properties and color. This allows our structures to work successfully for a long time even after the stipulated 40 conditional years of operation.
6. High accuracy of the geometric parameters of the profile is the key to the successful operation of window systems:
An important parameter for the profile is also the accuracy of the geometric dimensions of the profiles. Since plastic windows consist of many elements that match in a large number of sizes and surfaces, the accuracy of manufacturing the profiles themselves is the most important condition for creating a high-quality window unit.
The determining factors here are the recipe, which we will discuss below, the quality of the extrusion equipment and the experience of the personnel providing the extrusion process.
LG Hausys has been producing window profiles of a modern type for 30 years, having accumulated vast experience in this area. Naturally, the personnel involved in production also have extensive experience and qualifications.
The large production volume (more than 190 lines) and the widest range of products used in completely different markets also contribute to the accumulation of experience. At the same time, our equipment suppliers are European companies Weber (extruders) and Greiner (dies) - leaders in the market of extrusion equipment.
The combination of the above reasons makes it possible to ensure the accuracy of extrusion of LG window profiles with tolerances that are an order of magnitude more accurate than the requirements of GOST RF. Where GOST requires a tolerance within 1mm, our tolerances do not exceed 0.1mm, and often they are even lower.
7. Reasons that allow LG Hausys to produce PVC profile with unique technical characteristics:
What is the reason for the unique technical characteristics of LG profile systems? We note right away that all the above properties of the profile are primarily related to the recipe that our profiles have. Here LG Hausys has the potential to be incomparably greater than that of our competitors.
The quality indicators of the profile are highly dependent on the so-called additives, or additives. It is they that give it the specified physical and chemical properties (strength, plasticity, color stability). If the technological production cycle is disturbed, the chemical composition of the mixture changes, or an increased content of recycled PVC is used, the quality of the profile suffers greatly (over time, plastic windows turn yellow, freeze and deform in winter). Therefore, when choosing a window, the guarantees and reputation of the manufacturer are so important.
LG Hausys is one of the largest PVC manufacturers in the world. At the same time, we, of course, use raw materials of our own production in our profile systems, selecting the most optimal PVC brands for profile systems, taking into account the requirements of those regions where plastic windows from our profile will then work. The same goes for additives, most of which we also produce ourselves. Having experience in the creation and production of not only profiles, but also the raw materials for its production, independently creating the product during the full production cycle, we can really give PVC window profiles the properties that are optimal for this product. If necessary, it is possible to quickly make the necessary changes both in the design and formulation of window profiles, as well as quickly create new products required by our customers.
These are our profile capabilities, which our competitors do not have, and determine the uniqueness of the technical properties of the magnificent window profile from which plastic windows are made for you by our Eurostyle company!
All plastic windows must fulfill their functions, therefore, window structures are designed in accordance with all requirements. But quite often, as it turns out during installation, not all windows reliably perform their functions. The reason lies in the fact that the sample of windows may differ from the production batch. Also, it can be errors made during installation or errors in production. But are you looking for reliable windows that you want to be 100% sure of? Then you should pay attention to LGHAUSYS windows.
Plastic windows LG - high quality and manufacturing technology
LG PVC windows are an excellent choice if you want high-quality windows at a low price. The technology of manufacturing windows, as well as high hermetic characteristics, will make it possible to produce windows at the highest level. The quality of the windows will not depend on the manufacturer itself, as well as on the installers who will install the windows. In addition, LG windows have some other advantages:
1. Environmentally friendly materials. All profiles have a hygiene certificate, which confirms this. Moreover, the certificate is issued for all materials from which plastic windows are made.
2. LG windows have additional special seals. This allows you to protect the house from the most severe frosts, from wind and drafts. Windows are perfect for our region.
3. High degree of weldability of windows ensures longer service life. Windows can last for decades.

Premium German brand on the Russian market since 1995. With VEKA you get real German quality from a company with a 48-year history around the world.
- ALL profile systems of the highest class "A"
- ALL are frost-resistant and marked with the letter "M"
- ALL have maximum 4-sided steel reinforcement
- Uniform quality standard regardless of the country of production
The more air chambers, the less air exchange and, accordingly, the higher the thermal insulation.
The wider the profile and the greater the installation depth, the higher the thermal insulation.
Profiles ONLY top class "A"
According to the thickness of the inner walls, ALL of our profiles are of the highest class "A" - the thickness of their front wall is at least 3 mm.
- class "A": front wall not less than 3.0 mm
- class "B": front wall not less than 2.5 mm
- class "C": wall thickness is not standardized
Please note that 80-90% of the Russian market are "B" and "C" classes and only 10-20% of "A" class profiles. At the same time, VEKA's product range contains ONLY A-class profiles.
As a matter of principle, we DO NOT use profile systems of classes "B" and "C" (with a front wall width of less than 3.0 mm).
ONLY frost-resistant profiles
According to GOST 30673-99 "PVC profiles for window and door blocks" in terms of resistance to climatic influences, ALL of our profiles are "frost-resistant" - for areas with AVERAGE monthly air temperature in January BELOW minus 20 ° C.
GOST standards for different classes:
- normal version "N": the average temperature in January is minus 20 ° C and above
- frost-resistant version "M": the average temperature in January is lower than minus 20°С
In our assortment ONLY frost-resistant profile systems, marked with the letter "M".
Heat transfer resistance (thermal heat resistance) is the main coefficient of thermal insulation. It is determined by the ratio of the temperature difference outside and inside the room to the heat flow passing through the window. The higher this number, the better the thermal insulation efficiency.
Evolutionary double-glazed windows SmartGlass 2.0
Our multifunctional double-glazed windows work for you both in winter and in summer. In winter, sputtering of silver particles saves up to 90% of the heat energy of heating devices, and in summer a double-glazed window reflects 25% more solar heat than ordinary plastic windows.
- 42% more HEAT in winter (energy saving properties)
- 25% less HEAT in summer (sun protection properties)
All our double-glazed windows contain special energy-efficient glasses. We DO NOT use ordinary glasses even in the most basic configurations.
AirDrive I, II and III climate control systems
Optimal ventilation mechanisms are built into the windows - the sashes open slightly by 1-5 mm, depending on the selected mode. These are NOT external devices (combs or valves), but BUILT-IN furniture ventilation.
Three options:
- AirDrive I: night ventilation (1 mode)
- AirDrive II: discrete multi-stage ventilation (3 modes)
- AirDrive III: discrete multi-stage ventilation (5 modes)
We try not to install combs because of their appearance (only at your request). In principle, we do not use valves due to the fact that they violate the integrity of the window, reduce its tightness and strength (since the profile and its reinforcement are drilled through).
MAX steel profile reinforcement
Reinforcement is a steel frame inside a PVC profile. This is what gives it rigidity. The more steel and stiffness angles, the more reliable the window geometry.
Types of reinforcement:
- Square - 100% reinforcement on 4 sides, 4 stiffeners (maximum)
- U-shaped - 75% reinforcement on 3 sides, 2 stiffeners (normal)
- L-shaped - 50% reinforcement on 2 sides, 1 stiffener (very, very bad!)
All our profiles are reinforced to the MAXIMUM - from 4 sides and always with 4 stiffeners.
VEKA technologists managed to achieve a compromise between the unpretentiousness of a matte texture and spectacular gloss.
Pleasant shine and low sensitivity to external influences are the most noticeable feature of our window systems.
The VEKA profile complies not only with the Russian GOST, but also with the European building standard RAL.
