Before this, the polymer, along with fillers, plasticizers, softeners and stabilizers, melted until uniform, pulling material and passed through forms, then cooled. So it turns out a hollow profile with jumpers in air chambers. Excellent heat and sound insulation characteristics of the profile are achieved through the creation of a large number of hollow chambers. Perhaps another advantage is their cost. You can buy the windows Kharkov inexpensively at any time of the year. At the same time, the quality of the products remains at the invariably high level. This also needs to be remembered.
