Advantages of broken bridge aluminum:
1. Reduce heat conduction: heat insulation bridge breaking aluminum alloy profile is adopted, and its heat conduction coefficient is 1.8 ~ 3.5W / ㎡ · K, which is much lower than that of ordinary aluminum alloy profile 140 ~ 170W / ㎡ · K; The hollow glass structure is adopted, and its thermal conductivity is 2.0 ~ 3.59w/m2 · K, which is much lower than that of ordinary aluminum alloy profile 6.69 ~ 6.84w / ㎡ · K, effectively reducing the heat transmitted through doors and windows.
2. Prevent condensation: the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, reducing the possibility of indoor moisture condensing on the profile surface due to supersaturation.
3. Energy saving: in winter, the window frame with heat insulation strip can reduce 1 / 3 of the heat lost through the window frame; In summer, if there is air conditioning, the window frame with heat insulation strip can reduce energy loss more
4. Environmental protection: the application of thermal insulation system can reduce energy consumption and reduce environmental radiation caused by air conditioning and heating. ⊙ beneficial to health: heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. The most comfortable environment has been achieved by adjusting the indoor temperature of doors and windows to make it not lower than 12 ~ 13 ℃.
