In a descriptive article about Krauss windows, it has already been said that they are intended for glazing houses, summer cottages, cottages in areas with a warm or temperate climate. However, paradoxically, but on the Internet there are almost no complaints from users about the low cold resistance of windows with the "Krauss" profile.
Plastic profile systems KRAUSS
Due to the specially selected composition of frost-resistant polyvinyl chloride, Krauss PVC profiles are suitable for assembling plastic windows that can be used practically throughout the entire territory of the Russian Federation. The exception is regions with extremely cold climates. The resistance of structures to an unfavorable environment and frost is provided by unplasticized rigid polyvinyl chloride used as a raw material. The performance of this material is enhanced by the addition of calcium carbonate, color pigment, modifier and stabilizer. The basis of this synthetic material is the resin of the MITSUBISHI concern.
After bench tests of Krauss windows, it was concluded that in terms of their qualities these products are as close as possible to structures assembled from German KBE profiles. Such statements are not far from the truth, since Krauss PVC profiles are made from imported components on foreign equipment. Registration of the trade mark and localization of production in Russia allowed us to significantly reduce the price of products with good quality. Today, several types of these profile systems are available to domestic consumers.
Profile KRAUSS 5800 (Krauss 5800)
Since the profile system with 3 inner chambers has an installation depth of 58 mm, it is not recommended for use in harsh climatic conditions. It is advisable to use it when assembling window blocks for summer cottages, balconies and loggias, as well as warehouse and industrial premises. It is allowed to install Krauss 5800 windows in residential and office premises in the southern regions of the Russian Federation. According to experts, KRAUSS 5800 profiles are a high-quality analogue of KBE systems (Etalon). They are not adapted for the installation of anti-burglar fittings, therefore, they provide only a basic level of security.
Krauss official website
Having learned about the achievements of the company, the reader is obviously ready to rush to the search for the official website of "Krauss" in order to learn the details of both profiles and accessories. Company website address Krauss
.
But it won't be an easy task!
What is considered the official Krauss profile site?
Glazing of the cottage with the Krauss profile
There is a website okna-krauss.ru. It can even be given the title of the official site of the PVC "Krauss". But, frankly, he is not verbose about plastic windows either. And about the rest of the products with the Krauss trademark, no go-go!
Site] "Astek-MT" [/ anchor] although little by little tells about everything, but it is very laconic! It is better to look for technical characteristics of profiles, accessories on the website] Krauss RT [/ anchor] - an affiliated legal entity in the Republic of Tatarstan. There are more details, but this site, one feels, is aimed at production workers, engineers, subcontractors, and the mind of an ordinary buyer simply does not have time to absorb all those technical details that are very densely stated in dry, professional language.
Therefore, perhaps, acquaintance with the products of the Krauss brand is better to conduct on the usual selling sites such as "Multiokna" or window.msk.ru.
Profile KRAUSS 7300 (Krauss 7300)
A reliable 3-chamber system, in which, thanks to a 13 mm displacement of the hardware groove, it is possible to install reinforced locking mechanisms.The installation depth of these profiles is 70 mm, so they retain heat better than the KRAUSS 5800 systems. The windows assembled from such systems are suitable for use on the territory of the Central Federal District and can be installed in office and residential premises.
Profile KRAUSS 7500 (Krauss 7500)
The warmest of the entire range of PVC profiles is a 5-chamber system with an installation depth of 70 mm. The windows assembled from it can be used in regions where severe frosts are briefly recorded in winter. Removing the center of the hardware groove in the KRAUSS 7500 systems allows you to equip structures with reliable anti-burglary mechanisms. The depth of the groove for glass unit installation increased to 24 mm significantly reduces the likelihood of condensation formation around the perimeter of the skylight.
Methods for adjusting the pressure of the Krauss window sash (Krauss) to the frame
There are many manufacturers of window fittings and each of them has its own way of adjusting the sash pressure, but there are some general principles on how to tighten Krauss windows. Open the sash. Find the eccentric pins at the end of the sash. Most often they can be adjusted with a hex key or sprocket. Usually, there is a risk on the trunnion - a small strip. By default, it is put up - the neutral position. By twisting the pins to the left or to the right, you can strengthen or weaken the clamping of the window sash to the frame, i.e. change the winter-summer regime on your own.
Comparative table of KRAUSS PVC profiles
Depending on the brand, each Krauss profile system has a higher or lower coefficient of resistance to heat transfer, which determines the energy efficiency of the windows. When considering this defining parameter and the level of noise absorption, the thickness of the glass units should be taken into account. After all, it also directly affects the ability of structures to retain heat and sound.
| Profile type | Installation depth (mm) / Number of chambers | Maximum thickness of glass unit (mm) | Heat transfer resistance coefficient (W / m2 × ° C) |
| KRAUSS 5800 (Krauss 5800) | 58 / 3 | 32 | 0,78 |
| KRAUSS 7300 (Krauss 7300) | 70 / 3 | 40 | 0,80 |
| KRAUSS 7500 (Krauss 7500) | 70 / 5 | 40 | 0,82 |
Cleaning from dirt and lubrication of the Krauss window fittings (Krauss)
Start insulating Krauss windows for the winter by inspecting the window fittings. Remove dirt, especially from the top of the sash. All folds must be free of deposits and dirt, especially cement and plaster residues. Direct exposure of the fittings to moisture and contact with cleaning agents should be avoided. Then lubricate the window fittings with Krauss. The lubrication points of the Krauss window are marked with a special marking. How to lubricate a Krauss plastic window? The most common is WD-40, machine oil, grease. Never grease with sunflower oil or olive oil, or anything else! Edible oils dry quickly, turning into a sticky substance that will break the window mechanism. After that, rotate the fittings in different modes several times to distribute the grease. Wipe off excess oil from the Krauss window.
Aluminum systems KRAUSS
Under the KRAUSS brand, not only plastic profiles are produced in Russia, but also aluminum systems. They are used to assemble lightweight yet strong window or door blocks. Depending on the series, Krauss aluminum profiles are suitable for assembling "cold" or "warm" blocks. Profiles with higher energy efficiency have an additional polymer insert (thermal bridge) inside that retains heat. Without it, the number of chambers in the profile, the type of glass unit and the installation depth of the frame does not matter. The cold system is definitely not suitable for glazing any heated premises, since its use is irrational. In this case, all the heat will go away along the perimeter of the sash and frame.
Aluminum structures can last up to 80 years without changing basic performance and aesthetics. They have a high degree of resistance to deformation and wind loads. Such profiles are suitable for the assembly of both external glazing and internal dividing structures.These systems use EPDM-based rubber seals as sealing circuits. To equip window and door blocks from aluminum profiles with fittings, a Euro groove is provided. This allows the opening mechanisms of virtually all popular brands to be used.
The emergence and development of the Krauss brand
Krauss production line in Krymsk
But this is not the case.
Brand name Krauss owned by a Russian company Astek-MTfounded in 2002. In 2006, the company bought from an Austrian manufacturer of extrusion technology Technoplast four lines for the production of PVC window profiles and began to produce them under the Krauss trademark.
The production is located in the city of Krymsk, Krasnodar Territory. There is even an opinion that the first three letters in the profile designation are an abbreviation for the word Krasnodar. What the other three mean - everyone is free to guess! Maybe Union Soviet Socialist?
Krauss PVC Profile Extrusion
In 2007, thanks to investments from Turkey, Astek-MT managed to increase the number of extrusion lines for plastic profiles to 9 and to launch the production of aluminum profiles for glazing windows, doors, furniture sliding systems and aluminum structures for general construction. In addition, the company sells Turkish fittings for windows and doors. Fornax, including providing swing-out opening.
KRAUSS series KRWD-45 (Krauss KRVD-45)
The Krauss 45 system is intended for assembling only cold structures, as it is completely made of aluminum and does not have a heat-saving liner. Blocks made of these profiles have an installation depth of 45 mm. Such windows and doors can be equipped with both single glass and double-glazed windows. The area of application of the KRAUSS KRWD-45 systems is the manufacture of blocks for unheated entrance groups and internal dividing structures. Sometimes they are chosen when equipping cold balconies and loggias. The 45 series profiles can also be used for glazing commercial, warehouse and industrial unheated premises. Cold systems Kraus-45 are identical in their basic characteristics with the famous Spanish Provedal aluminum profiles.
KRAUSS KRWD-64 series (Krauss KRVD-64)
Profile system KRWD-64 is used for assembling warm door and window blocks, as it is equipped with polyamide thermal inserts, additionally reinforced with fiberglass for rigidity. Its installation depth is 64 mm. Although it is possible to install single glazing in structures made of these profiles, it is most often ignored. After all, it is advisable to use warm systems together with double-glazed windows, the maximum thickness of which is 47 mm. The system is recommended for use in southern regions.
Most common problems
Over time, any window product is exposed to a number of unpleasant factors as a result of normal wear and tear, poor maintenance or an emergency:
- The doors are seized and difficult to open.
- It blows from the window structure.
- Hardware breaks.
- The glass unit may break or crack.
Naturally, it is not necessary to immediately resort to extreme measures in the form of replacing the entire translucent structure. Most often, it is enough to repair it, which will cost you much less than a complete reinstallation.
KRAUSS KRWD-71 (Krauss KRVD-71)
Aluminum windows from the KRWD-71 systems with an installation depth of 71 mm are distinguished by high rigidity and strength of the joints. The presence of a thermal bridge inside the profiles makes these structures suitable for warm glazing of window openings, entrance groups, vestibules and heated balconies with loggias. Thanks to the increased installation depth and the possibility of integrating thick double-glazed windows, the blocks from the KRWD-71 profiles are characterized by increased energy efficiency.
Comparative table of KRAUSS aluminum profiles
Krauss is an aluminum profile, the thermal characteristics of which depend primarily on the presence of a thermal bridge. However, the installation depth of the frame and the thickness of the glass unit also affect the energy efficiency of "warm" windows from systems with a polymer insert.
| Profile type | System installation depth (mm) | Acceptable glass unit thickness (mm) | Sound insulation (dB) |
| KRAUSS KRWD-45 (Krauss KRVD-45) | 45 | 28 | up to 27 |
| KRAUSS KRWD-64 (Krauss KRVD-64) | 64 | 47 | up to 35 |
| KRAUSS KRWD-71 (Krauss KRVD-71) | 71 | 54 | up to 43 |
