Abstract

Today, the standard doors and windows one of the main requirements for the construction industry. Aluminum double glazed doors and windows have a special place in the world construction industry due to the variety of colors, resistance to atmospheric factors, product variety, beauty, etc. On the other hand, due to the weakness of the old aluminum profiles and their thermal conductivity, the craftsmen decided to place the polyamide blades between the aluminum profiles, to eliminate this weakness to a great extent and to insulate them. These types of profiles are known as thermal break aluminum profiles in the double-glazed doors and windows industry.
