Broken bridge aluminum is also called thermal insulation broken bridge aluminum profile, thermal insulation aluminum profile, broken bridge aluminum profile, broken cold and hot bridge profile and broken bridge aluminum-plastic composite profile. It has better performance than ordinary aluminum alloy profiles.
The "bridge" in the name "Broken Bridge Aluminum" refers to the "hot and cold bridge" in the sense of materials science, and the word "broken" means action, that is, "breaking the hot and cold bridge". Specifically, because aluminum alloy is a metal and conducts heat quickly, aluminum alloy can become a "bridge" for transferring heat when the temperature difference between indoor and outdoor is large. Using this material for doors and windows has poor heat insulation performance. Broken bridge aluminum is to disconnect the aluminum alloy from the middle. It uses hard plastic to connect the broken aluminum alloy into a whole. We know that the thermal conductivity of plastic is obviously worse than that of metal, so that heat can not easily pass through the whole material, and the thermal insulation performance of the material becomes better. This is the origin of the name "broken bridge aluminum (alloy)".
