Thermal insulation type aluminum alloy profiles can greatly reduce the heat transfer coefficient of aluminum alloy doors and windows. The heat-dissipating type aluminum alloy window frame refers to that the profile uses a non-metallic material to heat the aluminum alloy profile. The structure consists of two types of strip-type and perfusion type. The former uses high-strength reinforced nylon heat insulation strips (usually black) between the frames, and the latter is filled with polyurethane.
