Glasses have much

The use of two -chamber double -glazed windows increases more and more. Due to the fact that our current climate is harsh, a person has to turn to modern technologies more often, and more often the issue of insulation of his home is declining. In two -chamber double -glazed windows there are two cameras and three glasses that are filled with air or gas. And energy -saving coatings cost only two glasses and one camera. Such a set of parameters significantly exceeds two -chamber, which has been installed more common. But single -chamber glasses have much less weight, which quite well reduces the load on accessories, thereby extending the pile of operation.
