All window systems from PVC presented at the Russian market of construction materials are approximately identical. They consist of the plastic frames and double-glazed windows representing hermetically fastened sheets of special strong glass between which inert gas or vacuum is placed. When choosing plastic windows for the house it is worth paying attention to frames, i.e. to their profiles. All characteristics of your windows - durability, durability, warm and sound insulation will depend on them.
Instruction
1. Evaluate the plastic profile offered you visually. The high window has bigger light aperture, and it means that it will pass bigger amount of light.
2. Take an interest in profile thickness. At builders it is called assembly depth. The profile has deep assembly water, the will be warmer in your house.
3. Reduction of heatlosses through windows depends also on the number of cameras in profile. Ask the consultant with what number of cameras there will be profiles of your windows. The number of cameras for plastic windows can be from 2 to 7.
4. The following parameter of the choice of plastic profile for your window is, strangely enough, the double-glazed window. Learn glass thickness of double-glazed windows on which these profiles and also quality characteristics of glass are calculated.
5. You remember - than more thickly glass, especially your window will be soundproofing. And it is better to take windows with special low-emissivity glasses and with double-glazed window, filled with inert gas that also reduces heat emission and increases soundproofing.
6. For definition of strength loadings of profiles of windows ask to show you certificates of quality in which such indicators as durability have to be specified at stretching (standard value in accordance with GOST of 30673-99 not less than 37.0 MPas), impact strength (standard value across Sharpiya not less than 15 kJ/sq.m of GOST 30673-99), durability of angular welded joints (standard value in accordance with GOST of 30673-99 not less than 2000 N) and also quality assurance and durability.
