And although the main indicators of heat engineering PVC wooden windows concedes, the plasticity of the material and ease of processing allows to make from it the elements with high energy-saving measures. A durability of PVC and no need for any complex care provided plastic a number of major competitive advantages in comparison with wood bindings. If we talk about such a task as creating a Maximum heat box, then its solution involves several directions. First – this improvement of Thermal windows due to changes in the profile-factor, the second – using energy-efficient glass, and third – is a qualified professional installation. How then is it done? Traditionally, in Russia and CIS countries was dominated by window profiles with a mounting width of 58 – 60 mm.
They suggested that all manufacturers – German, Russian, Turkish and Chinese. Standard value of the mounting width of 58 mm appeared on the world not as a result of speculative calculations, and as the most cost effective solution to the problem of profile designs, especially the frame. With to a permanent tightening of requirements for energy efficiency has forced developers of specialized systems move towards increasing the circuit width. One of the first such system developed by the German VEKA, presenting the construction a series of market profiles TOPLINE. In 2003, VEKA has released another 70-mm profile system of classical design – SOFTLINE, which in 2005 began to produce and Russian forces group in Moscow and Novosibirsk. The second parameter, which may affect the profile of producers, is the number of chambers in the frame and sash. .
