Glass part of plastic window is 90% of its area. For this reason it is so important to pay attention to construction features of double-glazed window further not to be disappointed in purchase.
Modern double-glazed window – the most important part of plastic window; it has several versions, beginning from set of normal glasses and finishing with complex multichamber systems with the gas gone inside. What it is necessary to look when choosing double-glazed window at first of all?
Cameras
The simplest design – single-chamber. Represents couple of glasses placed at certain distance. Usually it makes 24-26 mm (depends on remote frame). It makes sense to use similar simplest double-glazed windows in southern latitudes, industrial premises. As in these products energy saving technologies are not used, application of single-chamber designs in more frigid climate leads to fogging of glasses.
The bilocular system is more perfect both in the sense of energy saving, and in respect of sound insulation. Average thickness of such double-glazed windows is 32 mm. They best of all are suitable for use in mid-latitudes. Sometimes glasses in package place at different distance. It allows to extinguish more effectively fluctuations of sound, protecting residents from noise from the street. Other way to increase quality of bilocular system – application of thicker (5-6 mm) of external glass. Three-chambered double-glazed windows are used only in rather severe climate or where increased requirements are imposed to sound insulation.
Energy saving technologies
If you need qualitative product, then pay attention to the possible ways of saving of heat offered by producers. The most widespread method – application of soft coverings for glasses in the form of films or firm sputtering in the form of low-emission structure. What does it give? The covering reflects in glass getting on it warmly back in the room. In addition, during strong heat the room will heat up less since the covering on external glass passes only light, but not warmly. One more method of saving of heat – filling of cameras inert gases: krypton, argon. If to compare to air, these gases less teploprovodna less teployemka. Molecular features of these chemical elements promote slower transfer of heat from the first glass to the second or third.
"Safe" double-glazed window
Nobody excludes possibility of destruction of double-glazed window. Therefore if in the house at you small children, then it is worth looking narrowly at "safe" designs. They assume use of tempered glass which is stronger normal by 5-7 times. At damage of such glass the product will break up into small pieces (up to 3 mm in size) which have no sharp angles. Other way to secure residents – use of the "triplex" familiar to motorists. Here use the transparent film placed between two glasses. At their damage the splinters just stick to the layer.
