Energy saving and heat preservation: the frame material and glass of aluminum alloy doors and Windows are important factors affecting thermal conductivity. The heat conduction coefficient of broken bridge aluminium door sheet design is only L /1250 times that of aluminum.
The ratio of heat transfer performance of PVC single glass aluminum alloy doors and Windows and single glass aluminum alloy doors and Windows is 1:2, so the heat insulation performance of broken bridge aluminum alloy doors and Windows under the same area conditions is better than that of ordinary aluminum alloy doors and Windows, which can save energy consumption of more than 30%.
