[0002] Broken bridge aluminum is also called thermal insulation broken bridge aluminum profile, thermal insulation aluminum alloy profile, broken bridge aluminum alloy, cold and hot bridge insulation profile, broken bridge aluminum plastic composite profile. It has better performance than ordinary aluminum alloy profile. Aluminum alloy is metal and conducts heat quickly, so when the indoor and outdoor temperatures differ greatly, aluminum alloy can become a "bridge" to transfer heat. Such materials are made into doors and windows with poor thermal insulation performance. Broken bridge aluminum is to break the aluminum alloy in the middle, and it uses hard plastic to connect the broken aluminum alloy into one. The thermal conductivity of plastic is obviously worse than that of metal, so it is not easy for heat to pass through the entire material, and the thermal insulation performance of the material is improved. This is "broken bridge aluminum". For example Figure 1 As shown, the air gap between the existing fixed frame profile 901 and the glass 12 is filled with an insulation strip 17, and water is blocked by a water-blocking rubber strip 18.
