Broken bridge aluminum

Broken bridge aluminum: cut off the hot and cold bridge, the aluminum alloy material is metal, and the thermal conductivity is about 200W/(m*K). When the temperature difference between indoor and outdoor is large, the aluminum alloy becomes the “bridge” for heat transfer, resulting in maintaining the indoor The energy consumption of temperature increases. The broken bridge disconnects the aluminum alloy from the middle, and then uses PA-66 (nylon-66) heat insulation strips to connect the aluminum alloys on both sides by piercing the strips. The thermal conductivity of PA-66 is generally 0.3W/(m) *K), so as to break the “bridge” of heat transfer to achieve the purpose of heat insulation.

Low-E glass: also known as low-radiation glass, using Low-E (heat insulation coating) tempered glass, with a hollow layer filled with more than 90% argon, which not only meets the needs of heat insulation, but also has good light transmission Rate; use high-quality EPDM rubber sealing strips on the frame fan and glass to meet the requirements of water tightness and air tightness。
