Thermal break aluminum doors and windows, due to having a layer of polyamide rubber inside the aluminum profile, in addition to reducing heat transfer, also increase strength, durability and vibration resistance. This polyamide layer used in aluminum doors and windows can reduce heat loss in the cold season by up to 39% and cooling energy loss in the heating season by 33%, which in turn reduces the initial costs of the heating system by about 21%. And 30% in reducing natural gas consumption. You can see all kinds of hinged doors and windows of AluTech company here.
