Window profile Grain Nordprof 58 (Grain Nordprof 58)

Grain is a domestically produced profile that is adapted for use in our climatic conditions. The range of systems allows you to assemble windows with different costs and thermal characteristics. These structures are designed for glazing residential, commercial and municipal buildings. Grainne's profiles began to be released in 2008. A plant for these purposes was built in Ufa with the direct participation of Austrian specialists. Over the 10 years since its opening, the company has increased its production capacity almost 4 times. This fact indicates the demand for systems from the Grain brand on the Russian market.

The Grain company supplies systems to all regions of the Russian Federation, where 30 of its dealerships operate, as well as to Belarus and Kazakhstan. The Ufa plant for the production of plastic profiles is one of the ten largest enterprises in Russia that produces components for PVC windows. In the production of Grain systems, Italian PLASMEC mixers and German Krauss Maffei extruders are used. To date, all the main stages of profile production have been automated, which has reduced the influence of the human factor and increased the quality of products from the Grain brand.

Grain profile systems

The Grain profile is represented by four series: Prestige, Nordprof, Lider and Vektor. They differ in the thickness of the outer and inner walls, as well as thermal characteristics. These parameters determine their cost. The Nordprof and Vektor series consist of two systems with installation depths of 58 and 70 mm. Lider also includes two types of profiles, but their depth is 58 and 102 mm. The Prestige series is presented in a single version - a 70mm system with 5 cameras.

For the manufacture of all listed profiles, a PVC mixture with a special recipe is used. Experienced specialists from the world famous Kronos, OMYA, BASF, Baerlocher, Reagens, Arkema and Sachtleben were involved in the development of the plastic composition. For storing the mixture, conditions have been created that eliminate the possibility of condensation. Feeding absolutely dry raw materials into extruders helps improve the quality of profiles. Thanks to the balanced composition of the mixture and adherence to technology, Grain windows have several important advantages:

• frost resistance up to -60°C;
• the ability to maintain a snow-white color for decades;
• high wall strength, exceeding GOST requirements by 2-4 times;
• maintaining the hardness of the plastic when heated to +80°C.

For the assembly of complex-shaped structures from Grain profile systems, auxiliary (additional) elements have been developed. The kit includes expansion, connecting, corner, bay window and stand profiles. The listed elements are universal - they were developed for the Lider system, but are also compatible with other Grain profile systems. Thanks to this, manufacturers can solve complex construction problems and glaze openings with any geometry.

The strength of welds in all series of profile systems from the Grain collection is 2.5 times higher than the regulatory requirements from GOST. Thanks to this, mechanical damage to structures in areas of rigid connection of window elements is almost completely eliminated. The reliability of structures assembled from Grain systems is facilitated by special protrusions inside the profiles. They help to better hold the fittings and increase the reliability of the fastenings.

The Lider and Prestige systems are complemented by body-dyed profiles in brown and caramel colors. In addition, it is possible to laminate the entire Grain collection with RENOLIT EXOFOL films, which protect the plastic from overheating when exposed to direct sunlight.

Features of Grain windows

The design of all windows involves a tape seal, not pieces, which must be joined in the corners. The uniform distribution of the tape eliminates even the hint of a draft. There is also a special system for fastening the hinges: the screw securing the sash passes through three walls, so the fastening is stronger and more resistant to loads. Another advantage of Grain is the internal geometry of the profile, with the introduction of additional partitions, so the fastening of the fittings is more reliable and the risk of deformation is reduced. The weak point of cheap plastic windows is the uneven thickness of the outer wall; as a result, after some time the entire window system becomes loose. constantly monitors the quality of products.

Profile geometry is not only a finely calculated design aimed at maintaining warmth and silence in your home. This also eliminates the risk of deformation and breakage of windows. The use of 13 fitting grooves in window profiles will reliably rid the house of “uninvited guests”. The thirteenth system, unlike the common ninth, has sheer parts offset outward from the hinges. This prevents damage and deformation, which means it provides better protection against burglars and robbers. At the same time, the windows “get along” well with all types of anti-burglary fittings.

At first glance, all plastic windows are equally white. But glossy windows, when new, make a spectacular impression, but any scratch on them immediately catches the eye. Matte ones, on the contrary, “hide” minor mechanical damage, but they also don’t look so impressive, modest, already worn. But the employees decided not to choose, and combined the beauty of gloss and the practicality of a matte surface in their materials. Thanks to new technology, Grain windows look as good as new even after several years of use, and their whiteness is pleasing to the eye. So not all windows are equally white.

Profile Grain-Prestige 70 (Grain-Prestige 70)

This universal 5-chamber system is perfect for assembling windows that can be used in all regions of Russia (with the exception of the northern regions). Although a class “A” profile with an installation depth of 70 mm can withstand frosts down to -60°C, the energy efficiency of structures assembled from it is not sufficient for very harsh winters. But for the center and south of our country, the Grain-Prestige 70 system is the best option.

The internal chambers of Grain-Prestige profiles have additional partitions. They not only increase the rigidity of structures, but also increase the level of heat conservation. Due to the small optical height (112 mm), windows assembled from these systems have good light transmittance. To ensure tightness, the developers limited themselves to 2 sealing contours, since the excellent rigidity of the profiles reduced the likelihood of blowing through the valves to a minimum.

PVC profile class "A"

Class “A” profile has the best performance characteristics and is recommended for glazing of residential buildings, office premises, children's and medical institutions. The thickness of the external front walls of the Grain-Prestige and Grain-Lider profiles is 3 mm, the non-front walls are 2.5 mm, almost at the upper limit of the requirements of GOST 30673-2013. Accordingly, such a profile is stronger, more resistant to impacts, and the window structure is stable, durable and retains heat better.

Grain Leader 58

Classic three-chamber window system Grain-Lider class “A”. It has high performance characteristics, providing reliability, strength, heat and sound insulation. This allows Grain-Lider to be used for residential, office premises, children's and medical institutions.

The 13 mm distance of the fitting groove allows the installation of anti-burglary fittings.

Additional reinforcing partitions and technological protrusions in the internal chambers of the profile increase the strength of fastening of locking and load-bearing elements and reduce the number of cold bridges.

Thanks to the versatility of the internal geometry of the frame, it became possible to install closed reinforcement. This makes it possible to produce non-standard structures that are safe to use (subject to compliance with static calculations).

Grain-Prestige 70

The premium window system Grain-Prestige has improved performance characteristics, which allows it to be used in all climatic zones, using it for residential, office premises, children's and medical institutions.

Grain Leader 102

In combination with a 102 mm wide frame, thanks to the presence of two additional chambers in the frame profile, the three-chamber Grain-Lider window system has increased sound and heat insulation properties. This allows you to significantly reduce the cost of maintaining a stable room temperature. Therefore, windows made from this combination of profiles are successfully used both in the conditions of the Far North and in the warm climate of the Krasnodar Territory. High performance characteristics make it possible to use the Grain-Lider window system with a wide frame in residential and office premises, in children's and medical institutions.

The combination of the classic Grain-Lider profile with a wide five-chamber window frame allows you to increase the heat efficiency of the entire window structure by 20%. In addition, a wide frame with increased installation depth provides improved thermal insulation of slopes.

A distinctive feature of the five-chamber wide Grain Lider frame from analogues on the market is that the reinforcing profile of the frame has been moved to a warm zone.

Additional reinforcing partitions and technological protrusions in the internal chambers of the profile increase the strength of fastening of locking and load-bearing elements and reduce the number of cold bridges.

Profile Grain-Lider 58 (Grain-Leader 58)

Profiles with a 58 mm installation depth can theoretically be used to assemble windows that are planned to be used in areas with moderately cold winters. However, in practice, three internal chambers may not be enough in severe frosts, so it is better to choose warmer profiles for such regions. At the same time, in the southern latitudes of the Russian Federation, the Grain-Lider 58 dual-circuit system fully copes with the functions assigned to it.

Profile Grain-Lider 102 (Grain-Leader 102)

Because so much heat from windows is lost into the walls, Grain engineers created a wide-frame system. Its installation depth is 102 mm, which helps to increase the energy efficiency of the rest of the structure. The Grain-Lider 102 system was developed for use in northern latitudes. It is also recommended for use when assembling windows intended for use in temperate climates. Grain-Leader 102 windows reduce heat leakage to a minimum and help save on heating costs. In terms of the thickness of the plastic walls, they belong to class “A” profile structures and can be equipped with burglar-resistant fittings.

To make the cost of the Grain-Lider 102 system accessible to a wide range of buyers, the developers resorted to a trick. They created a 5-chamber profile for the frame, and a 3-chamber profile for the sashes. In this way, it was possible to insulate the most problematic area of ​​the windows - the frame, because in fixed and active sashes the energy efficiency of double-glazed windows is more important. Moreover, the chambers in the frame were additionally divided by a horizontal internal partition - in fact, this profile has 10 internal cavities. Thanks to this distribution, the frame has double protection, preventing heat leakage from the windows into the walls. This technique increases the level of energy saving of profile structures by 20%.

PVC profile class "B" economy

The plastic profile from the Grain company complies with all current norms and standards, has the necessary certificates and sanitary and epidemiological conclusions. High-quality components, strict execution of the technical process, and strict quality control allow us to install a warranty period of up to 60 years on Grain profile systems.

Profile Vektor 58 (Vector 58)

This 3-chamber system is actively used not only for glazing loggias, country houses, warehouses and industrial premises. Vektor 58 profiles are used for assembling windows intended for installation in residential and office premises. However, given that the energy efficiency of structures made from this system is almost 20% less than that of frames and sashes from Grain-Prestige 70, its scope of application is limited to the southern regions. In severe frosts, structures made from Vektor 58 systems lose too much heat, so maintaining a comfortable temperature in the interior requires more resources. Vector 58 windows are only good for mild winters.

Feedback about Grain's profile

For glazing, you can safely use the Grain profile, reviews of which clearly indicate that these systems are highly appreciated in the Russian Federation. Grain windows today are successfully used in apartment buildings, private cottages and commercial or municipal institutions. Depending on the circumstances, customers choose different types of profiles, but they respond best to the Grain-Lider and Grain-Prestige systems. These premium series are not inferior to similar products from European manufacturers.

Vladimir Semenovich (entrepreneur): “To replace windows in the office, I chose the Russian Leader system with a wide frame and conventional three-chamber sashes. I think this combination is the most reasonable. After all, good double-glazed windows protect you from the cold from the street, but windows on the side of the walls are the most vulnerable. The numbers speak about the effectiveness of this system. After installing new Grainne windows, I reduced my heating payments by 15% and literally in 2-3 seasons I will get back the money spent on an improved profile.” Valentina Germanovna (teacher): “For the new windows I chose the Grain profile, reviews of which influenced my final decision.
At first I thought of giving preference to some well-known and popular brand, but at the same time I wanted to save money. Ultimately, after some thought and questioning, I ordered windows from Grain Prestige profiles. I'm glad I made this decision. New windows look great, retain heat for a long time and keep out noise.” Grain is a PVC profile that is manufactured in strict compliance with the specified parameters. Stable quality indicators mean that the actual characteristics of the systems fully correspond to the parameters declared by the manufacturer. The customer is only required to correctly choose the optimal model and regularly care for the plastic structures and fittings.

We are aware that by rating windows, we are thereby invading the territory of professionals who are very skeptical about the ratings of this product. But “Expert Price” would not be himself if he had not tried to rank everyone.

Most people, and visitors to window salons are no exception, love with their eyes. No matter how unique the characteristics of a plastic window may be, it is extremely important that it pleases clients in appearance and/or allows them to realize their design project. An example of a solution that combines elegance of form and exceptional heat-protective properties is the new REHAU product - the GRAZIO window system. Despite the impressive depth (70 mm), the profile seems light and sophisticated. In many ways, this effect was achieved thanks to the original bevels of the front surfaces of the main profiles. The new product instantly catches the eye and distances itself as much as possible from “ordinary” white windows. At the same time, behind the characteristic “shell” there are technologies, the use of which has made it possible to reduce the heat transfer of the profile, as well as its cost. The protective properties of GRAZIO have been confirmed experimentally: according to the results of laboratory tests, the system can be recommended even for regions where the thermometer scale drops to minus 40° C.

The new product is intended for the production of plastic windows and balcony doors in Saratov and is suitable for both individual and facility construction. Depending on the customer’s needs, the profile can be supplied in a traditional white design or decorated with special films in various colors, including ones that replicate the structure of wood.

Other advantages of GRAZIO for manufacturers of window structures include:

· the recognizable REHAU brand, which has repeatedly become the No. 1 brand on the Russian PVC profiles market;

· processing of the system does not require additional investments in equipment, only a new template for attaching the impost and an impost cutter are needed;

· the product is fully compatible with other additional REHAU profiles with a depth of 70 mm;

· the profile design involves the use of standard REHAU reinforcement 35x20 and 25x28 mm and a seal of one of two widely used standard sizes;

· original mechanical connectors and seam inserts guarantee high performance of products;

· all GRAZIO profiles are produced with standard REHAU protective film;

· new universal template for fastening the impost, the same for all 70 mm REHAU systems;

· Possibility of installing reinforced locking devices.

The GRAZIO profile is available for order for direct shipments from REHAU warehouses and through certified partners of the company. More detailed technical and commercial information can be obtained from the managers of REHAU regional sales offices.

Which profile of plastic windows is better?

To understand the subtle nuances of the assessment, we had to study a considerable amount of informational texts, a huge number of all kinds of amateur and professional reviews, and conduct a small amount of our own research.

The product, about which so many copies have been described, is in fact the most ordinary plastic stick, but, however, with a complex surface and internal structure. To give strength, there is a metal insert made of galvanized steel inside the profile, and internal plastic partitions create air chambers that ensure heat conservation. All. It seems, what is there to argue about? Steel will remain steel no matter what is done to it, and the plastic used by all companies is the same - polyvinyl chloride (PVC). It follows that the window profile of any production must be of the same quality. Is it so? And how do you choose the best from what is identical by definition?

Criteria for choosing a profile

Country of origin of the profile

Any company that recycles a window profile indicates its origin. At the same time, you can very often find the word “German” in the descriptive part. We recommend that you clarify what is meant by this word, because... Sellers like to use it to justify the high price of a finished window. The lion's share of this profile is produced in Russia using German technology. In this case, relatively cheap energy resources and labor are used, therefore, the cost of the product should differ from the profile produced in Germany.

Number of thermal insulation chambers

Of course, the most important criterion. It is believed that the more chambers, the better the thermal insulation. However, do not forget that an excessively large number of chambers can lead to the fact that the thermal conductivity coefficient can, on the contrary, increase due to the plastic partitions, which will act as a cooling radiator. Therefore, we definitely pay attention to the following criterion.

Profile width

When choosing a profile for a living room, it is better not to skimp on this parameter. Everything is simple here, the wider, the warmer. It is only worth noting that small-chamber wide profiles can be easily deformed, because have few stiffeners.

Number of double-glazed window chambers

We advise you to choose only two-chamber ones, even for glazing loggias - do not forget, the miser pays twice. However, choosing a double-glazed window is a topic for a separate article.

Reinforcing steel insert

It comes with an open or solid contour. If there are no restrictions on strength, then we advise you to choose an open one, it is warmer.

Advantages of plastic windows with NordProf profile

The observed widespread popularity of the Nordrof PVC profile is primarily due to its excellent technical characteristics:

• improved thermal insulation properties,
• thorough sound absorption,
• strength and reliability,
• not susceptible to temperature changes,
• durability.

This window system is distinguished by the presence of 5 internal chambers in all profiles (including impost). This design allows one to significantly improve the thermal insulation (and at the same time sound insulation) of the window, as mentioned above.

The NordProf profile is equipped with reinforced technological protrusions, which makes it possible to attach fittings particularly securely. For example: the strength indicators of fillet welded joints exceed the standardized values ​​by 2.5 times.

Thanks to the installation of closed-type reinforcement into the frame, the production of non-standard structures becomes possible. With strict adherence to statistical calculations, it is possible to create stained glass windows of any level of complexity, transparent office partitions, etc.

Add here ease of use, ease of maintenance and a presentable appearance, which allows you to successfully fit such a double-glazed window into any interior - and you get a comprehensive universal solution.

Which plastic windows are still better to install?

And in the end, the main thing is that a careless window manufacturer or a handsless installer can turn the best profile into disgusting trash. Therefore, before ordering windows, consult with neighbors, friends or just acquaintances who have already contacted the company you have chosen. Remember that a profile is just a piece of plastic, which, although it is an important component of a window unit, its choice must still be justified in combination with such factors as reliable fittings, a good double-glazed window and the conscientiousness of the craftsmen.

Plastic windows Grain

- high-quality Russian windows according to European standards, but taking into account Russian climatic conditions and prices. The Grain company specializes in the production of PVC profiles for doors and windows. This project was developed by Greiner specialists. In particular, Austrian specialists designed unique tools, extrusion lines and the profile system itself.

A modern manufacturing plant for plastic windows is located near the city of Ufa. Qualified workers are responsible for the smooth and high-quality operation of the plant, and all products undergo strict and careful testing at all stages of production. Leading specialists of the Grain plant trained and learned from Austrian employees. European standards are the guarantee of the quality of Grain plastic windows, and this is proven by certificates of conformity and the trust of customers throughout Russia.

A special place in production is occupied by product quality control. Control is carried out in several approaches: first, specialists check the quality of purchased raw materials. Then all stages of the automated process are checked. And finally, the finished products undergo final quality control in a specialized laboratory equipped with modern equipment.

Control over the production of Grain windows is much stricter than required by Russian GOSTs, as it is based on European quality standards. In addition, it does not stop in its development and actively cooperates with companies leading in the world of the chemical industry: Chemson, IKA, OMYA. Therefore, you can without a doubt resolve the dispute about whether to choose “European or Russian plastic windows?” in favor of domestic ones.

A pertinent question arises: what is meant by “European quality standards”? Answer: environmentally friendly, durable, low sound permeability PVC profile. Since the manufacturing technology of these profiles was actually carried out in Austria, it is logical that Grain windows meet very stringent environmental safety standards. This is ensured by both raw materials and testing for atmospheric and chemical resistance.

In terms of airtightness, plastic windows "Grain" pass into class A, due to the thickness of the front and non-front walls. This guarantees dimensional stability and strength. High-quality materials and modern technologies provide an excellent heat transfer resistance coefficient, above 0.80 m2/W. All window models have passed various quality and compliance tests, including very original ones.

Grain's profile systems are designed for the production of plastic windows and doors for any premises and are specially adapted to the requirements of Russian consumers. The main Grain profiles have class A in terms of the thickness of the front and non-front external walls, which confirms their maximum dimensional stability and strength. According to the reduced heat transfer resistance, the profiles of the Grain system belong to class 1 - their reduced heat transfer resistance is over 0.80 m2 x ° C / W.

Plastic windows Grain

– These are Austrian window technologies transferred to Russia, thanks to which the Grain profile fully meets stringent European environmental safety requirements. When developing the Grain system, changes were made to the internal and external architecture of the profiles, which are designed to improve their performance, enhance the functional effect of some elements, and also simplify the process of manufacturing and installing window structures.

The technological process for producing Grain profiles is fully automated, from dosing PVC resin and additives to placing finished profiles on pallets. The quality of the finished product is ensured by continuous computer monitoring of the most important parameters at each technological stage. The Grain laboratory regularly tests samples of finished products according to all indicators provided for by GOST.

The production project was developed by the famous Austrian company Greiner, with which long-term relationships have been established. A world leader in the creation of extrusion dies, Greiner manufactured unique tools and the extrusion lines themselves for this project. Greiner specialists also designed a system of profiles, which is a guarantor of the European quality of Grain products. The recipe for the Grain profile raw material was specially developed for the Russian market by leading specialists from the world-famous company IKA. During the development, harsh climatic conditions were taken into account, many tests were carried out, and advanced technologies from leading European companies were used.

Thanks to this, the Grain profile has increased resistance to temperature changes, as well as high frost resistance. This is confirmed by certificates and tests that were carried out at temperatures of –55°C and +75°C. These indicators indicate the high quality of the Grain profile, which will save heat in the house even in the most severe frosts.

Currently, “is a dynamically developing enterprise that has proven itself at a high level in more than 15 regions of the Russian Federation, as well as in the Republic of Belarus.

Benefits of the Grain profile

The most important part of any window is the profile. It ensures the integrity of the entire window structure, determines its strength, heat and sound insulation characteristics. The service life and durability of the window depend on the PVC profile from which the window is made.

That’s why the Grain factory pays so much attention to the quality of the profiles it produces.

Created specifically for Russia

The climate in Russia is unpredictable, which is why plastic windows are used in harsh conditions of cold and heat. Therefore, it produces not just frost-resistant profiles, but ones that are resistant to significant temperature changes from -60 to +800C.

Grain profiles belong to the 1st class of heat transfer resistance and class “A” in terms of the thickness of the front walls, which is the highest indicator for a PVC profile according to GOST 30673-99.

Increased sound insulation

In megacities, where houses are adjacent to busy highways, railways, stadiums and industrial facilities, it is extremely important to maintain a noise level in the apartment that is comfortable for the human ear.

Plastic windows made from three- and five-chamber Grain profiles have a high level of sound insulation. On a three-chamber profile you can install a glass unit with a width of 32 mm, on a five-chamber profile - 40 mm, which allows you to reduce the noise level to 26 dB.

Complete sealing

The heat and sound insulation of a future window is also affected by the quality of the seal. Grain's range includes profiles with TPE (thermoplastic elastomer) sealing. This seal has excellent ozone and UV resistance, is highly durable and flexible (even at low temperatures), durable in use and chemically resistant to most chemicals. Profiles with TPE seals, due to their high thermoplasticity, are perfectly weldable and provide a reliable seal in the corners of window structures.

High level of security

Grain PVC profiles are necessarily tested for strength. According to test results, the strength of Grain profiles exceeds GOST requirements by 2-4 times.

All window structures made from the Grain profile, according to the technological parameters (removal of the 13 mm fitting groove), are suitable for equipping with anti-burglary fittings that prevent the sash from being dismantled from the outside. In addition, the geometry of the PVC profile contains special protrusions that increase the reliability of fastening conventional and anti-burglary fittings.

Reliability and guarantee

Windows from the Grain profile will protect your home from harsh weather conditions, excess noise, and break-ins for many years.

The Grain profile will not change its geometry during operation thanks to the front walls of class “A” and reinforcing elements. The strength of corner joints of Grain profiles is 2-4 times higher than GOST values. The color of the Grain profile is stable, since only high-quality components in the required volume are used in production. The use of innovative technologies guarantees the preservation of high quality and durability of plastic windows for 40 years.
