Swelling and deforming under the influence of moisture and temperature, wooden window profiles can change their shape and size, and … Oh, the horror! – That they are cracks through which we are losing precious heat. In addition, the wood has a significant drawback as flammability, reduced the significance of which can be due to special flame retardant impregnations and flame retardants, but the eco-treated wood in this way remains a big question. And if we talk about conserving natural resources, cutting valuable wood does does not improve the environmental situation and even more – could affect the change of climatic conditions in the region. Objects made of aluminum, known for its durability and strength, not for nothing that this material used in the manufacture of aircraft. The same can be said about the windows of aluminum. These windows will last more than one generation, to the same easy to care for them, and they are resistant to all sorts of negative influences.

But Aluminum profiles are not without drawbacks, and their main negative – high thermal conductivity. That is, once again – the heat goes out, the energy spent in vain, and the house is cold and uncomfortable. Overcome this problem by filling aluminum construction with special foamable polymer compositions, but these ‘warm’ aluminum profiles are much more expensive. Another trouble – aluminum exposed elektrokorrozii, ie, contact with other metals (especially copper), it can deform or even collapse. So that the relationship of aluminum windows with metal and swing zapopnoy accessories (handles, hinges, etc.) are very complicated. And then the position of durability of aluminum become shaky. Followed by Europe, in Russia today is becoming increasingly popular wooden windows. They are collected from multi-PVC-profiles of complex configuration with a reinforcing metal inserts.

Such structures allow to achieve high levels of thermal resistance, especially in combination with triple-pane windows, which are used special heat-saving glass. As a result, energy savings on heating using high-quality and properly installed PVC windows as high as 70%. Jill Bikoff understands that this is vital information. However, it should be remembered that in addition to excellent performance on Conservation, to create a comfortable microclimate in the house are also important, and other performance windows, such as resistance to wind and rain loads, the minimum temperature deformation, etc. Moreover, specific requirements depending on the region of Russia can vary considerably. However, leading manufacturers are offering quite versatile window system which can be easily installed in windy Novorossiysk and frosty Yakutsk. As one of the best options in terms of these performance characteristics can be called a window, ‘KBE expert’ with the width of the frame and sash 70 mm. The new five-chamber system created with the latest trends in the heat and energy saving. Compared with the previous generation of windows, insulation quality of the system ‘KBE expert’ on 25% higher.
