Why Windows, Rather Than Wooden ?

Any normal residential house, must necessarily have walls, roof, doors and windows. Asking whether you ever yourself, "what a person needs windows?". First and foremost, of course, to illuminate the room, because nobody want to pay extra money for electricity, if at the time of the window there is a free source of light. Second, the windows are needed for ventilation, as in a closed room, sooner or later, the air going negative and harmful substances, from which you want to get rid of, and man is always pleasant to breathe fresh air. The third factor, which confirms the justification for the presence of windows in the house is just a pleasure views, and in this case, the binding conditions are the presence of a beautiful, modern and clean windows.

Since ancient times, over many generations the people used as frames for the windows of wood, that in our, modern age, simply not justified for many reasons. Everyone knows that the tree is well lit and, therefore, in fire houses in the first place, it will be exposed to fire, wooden items, including frames, as well as wood emits large amount of heat, then spread the fire rapidly, it will be enough. Another important fact of obsolescence of technology of frames made of wood is that heat and sound insulation properties of wood are very far from ideal, which ultimately leads to loss of heat in the house and the presence of excessive street noise. Due to the fact that wood is the material that was created by nature itself, which did not involve the use of wood as a material for durable windows, then it is not surprising that the wooden frame is sufficient to react adversely to the low and high temperature and humidity, and, accordingly, can quickly crack from dryness under the influence sunlight and lose its original shape and color.

Federal State Statistics Service

Manufacture of metal until the mid 2008 on the Russian market experienced strong growth in production, but due to the economic crisis, the production of metal construction has dropped dramatically. According to the Federal State Statistics Service in the country in January 2010, it produced 394 tons of structural steel. In general, 1 half 2010 production of metal was 96,5%, the Tier 1 pol.2009 The continuing decline in production due to the slow recovery of industries – consumer products after the crisis of 2008-2009. According to President of Russian Union of Metal suppliers Alexandra Romanov, the market metallotreydinga and metal production returns to pre-crisis level until 2015 when the growth rate of 5-10% per year. The main producers of construction steel structures are concentrated in the Chelyabinsk, Omsk and Moscow regions.

In this case, the Moscow region is leading in the number of small producers. Reduction in the production of steel building steel in 2008-2009 was observed in all regions, the most significant drop occurred in the Chelyabinsk region, where in 2009 the production of steel decreased by 40% compared with 2008 steel imports despite steady production of steel in Russia, the volume of imports metal remains high. Imported steel constructions can be found in European Russia (suppliers from Finland, Belarus and Slovenia) and the Far East (China, Korea). Hear from experts in the field like Mashable for a more varied view. The bulk of Made in Russia building metal remains in the country. Therefore, in further calculations, the volume export market was ignored. Market share of main steel products made in Russia building metal remains in the country and fully used in construction. Therefore, in further calculations, the volume of the export market was ignored. Key players in the market of metal Russian market of steel production construction steel in Russia is highly competitive.

Federal State Statistics Service allocates about 750 company-producers. The bulk of producers are located in the cfd and ufd, large about 10. In this case, the order of 50-52% generic manufacturers produce 70% of all metal. The leading Russian manufacturers of steel building structures are concentrated in Kurgan, Chelyabinsk, Ulyanovsk, , Sverdlovsk and areas.

In the post-crisis economic recovery most promising sectors of consumption of steel are considered housing and commercial real estate sector. Meanwhile, in the construction industry is traditionally the most capacious orders (estimated experts, the average capacity of 1 order of 1000-1200 tons). continuation "

Wood Houses

And the 'elite' wooden wall material – laminated veneer lumber just extremely rarely produced thicker than than 21cm – because of the peculiarities of the technology. And he stands, if a high – over $ 850-950 per cubic meter (a safety adhesive used – almost always topical issue). That is, now houses made of wooden materials simply can not be used without additional warming. So, in any case impossible to get a natural wooden surface of the walls in the house, and, moreover, will have to spend quite a lot of their own forces and funds for special insulation, which in turn will lead to a plausible (and rather common) problems of safety and environmental protection heaters. Thermal conductivity of building blocks from Arbolita, used to house up to 3 floors – 0.12-0.14 W / m * K. Accordingly, the thermal efficiency of their dominance over the tree from 20% to 160% (it is worth remembering and the weakening of heat-insulating properties of walls of wooden houses on the occurrence of cracks, saturated with moisture and other aspects). The thickness of the standard building blocks of Arbolita – 30 inches, therefore, houses are even warmer than those legendary – from half a meter of logs. And this is confirmed by many decades of successful operation of houses of Arbolita even in the most northern regions of Russia. Easy combustibility of wood materials has always been one of the main problems – the latest means of a little lower level flammability, but the effect is relatively small, and decreases with time.

Commercial Director

"Production of European-style – is not only the latest equipment and technology but also multi-tiered system of quality control – says Leo Minullin, Commercial Director, td propleks (the exclusive supplier of pvc profiles produced in Russia in the Austrian technologies). – We are working on the Austrian extrusion equipment for the compounding of the raw mix, developed by experts of this country for Russian conditions. Composition of components adapted to our climatic conditions, in particular, to a frosty winters. Moreover, additives (pigments, stabilizers, plasticizers, etc.) are delivered to us directly from Austria ". Each batch of raw material input is hard to control quality control laboratory at the plant propleks.

Regularly carried out tests on samples of products according to parameters such as strength, heat resistance, color surface. A special climate control simulated weather effects in real-world conditions. Samples of the profile is subjected to several tens of cycles of wetting and exposure to ultraviolet light, and then examined for signs of damage, changes in color and strength characteristics. If the samples did not pass at least one test, reject the entire batch of profiles, as manufacturing technology is adjusted to eliminate the violations. Such a quality control system to meet most severe European standards, ensure that the profile was released at a factory in Moscow or Siberia, is no different from fellow extruded somewhere Bavaria or the outskirts of Vienna. However, Russian consumers are often unaware that the "pedigree" of pvc profile and its quality – this is not the only conditions for long life plastic window.
