windows have undergone a reasonably small transformation to the usual formulation of the windows from a block of wood.The same sash placed in a window envelope, the same window zatvorki, glass and - the absence of nanotechnology.However, the use of new construction materials: metal sheets, high-quality polymers, significantly enhance the reliability of the windows, their reliability, durability, aesthetic and ergonomic exhibitors.
Today, plastic windows are borrowed not only as a part of the device encircling the buildings (walls), as well as device windows, conservatories and even skylights rather mnogoznachaschih premises.This widely used guaranteed, above all, the use of the metal profile and the probability of its special steel linings multiply.
Currently popular method of education allows them to windows operating asset is comparable to the operational life of buildings, which directly affects the structure of the main economic factors.
windows corresponding index remained unchanged.Guidelines of them - the transmission, thermal and acoustic insulation.Light transmission element (glazed) characteristic is generally about 90% of the window unit.In the great majority of cases it is made from high-quality float glass marks M1, M2.
Fit heat and sound insulation of plastic windows is formed by a multi-chamber tightness glass and metal sheets, in addition, the greater the space between the panes, so the data above.The manual distance is announced in the area of 8 to 36 mm.It is set to image and the strength of the glass.It depends primarily on the volume of the glass and wind pressure.
At the time, plastic windows have gained a special function to restrict access to the building by unauthorized persons.This enables the production of glass using armored or reinforced glass and installed between the window frame and sash vandal-proof protection devices.Given such popularity of plastic windows include increased functionality by mounting a strong locking hardware.Stylistic subordination of glass with almost every house facade allows him an excellent view.
