Thermal break is an innovative method for improving the thermal insulation performance of doors and windows, especially for aluminum alloy doors and windows. It forms an insulation layer by adding insulation materials (usually nylon 66 or other engineering plastics) in the middle of aluminum alloy profiles, thereby effectively blocking the transfer of heat and reducing the heat exchange between indoors and outdoors.
It has good performance in sound insulation, heat insulation, waterproofness and airtightness.
