What is a "broken bridge" aluminum door and window

Broken bridge aluminum doors and windows are not much different from aluminum alloy in appearance, and they are also aluminum alloy doors and windows. In fact, they are all upgraded and improved versions of aluminum alloy doors and windows, and the difference lies in its "broken bridge" technology.

insulating trip

The most important part of broken-bridge aluminum doors and windows is the heat insulation strip in broken-bridge aluminum. At present, there are two kinds of materials used for heat insulation strips, one is PA66 nylon heat insulation strips (made in Europe, extruded with cavities) and the other is polyurethane glue injection (made in America, cast, mostly without cavities).

thermal insulation

Broken aluminum doors and windows are blocked with materials with poor thermal conductivity to achieve the effect of heat insulation. The so-called "bridge" refers to the hot and cold bridge on the building. Cold and hot will spread rapidly through metal, and the function of broken bridge is to break cold and hot with different materials and block the circulation of heat.

Process upgrade

Broken bridge aluminum doors and windows are upgraded and improved versions of aluminum alloy doors and windows, and the difference lies in its "broken bridge" technology. Traditional aluminum alloy doors and windows, because metal conducts heat faster and the temperature difference between indoor and outdoor is relatively large, aluminum alloy has become a "bridge" for heat transfer. Broken bridge is to disconnect the aluminum alloy from the middle and connect the aluminum alloys on both sides with gaskets with low thermal conductivity. The heat is not easy to transfer, so it is called "broken bridge" aluminum.
