What is the structure of broken bridge aluminum doors and windows?

The two aluminum frames are connected by hard plastic (black part), which cuts off the conduction function and plays an energy-saving role. Because the two aluminum alloy materials are connected together, the whole supporting force is greatly enhanced and the bearing capacity is good! The black material in the middle is a heat insulation strip. Because of thermal insulation materials, aluminum alloy doors and windows are called thermal insulation broken bridge aluminum alloy. The insulation strip plays a vital role in the broken-bridge aluminum window, so the brand broken-bridge aluminum uses PA66 nylon strip, but some merchants use cheaper PVC plastic insulation strip. Good quality insulation strips are soft and not easy to age and deform. All brands of broken bridge aluminum are still different from those of miscellaneous brands. It is best to choose brand broken bridge aluminum for household broken bridge aluminum.
