1. Reduce heat conduction: heat insulation broken bridge aluminum alloy profile is adopted, and the thermal conductivity 1.8 ~ 3.5 W/㎡ k is much lower than that of ordinary aluminum alloy profile. 2. Anti-condensation: the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of condensation on the profile surface due to oversaturation. 3. Energy saving: In winter, the window frame with heat insulation strips can reduce 1/3 the heat lost through the window frame; If there is air conditioning in summer, the window frame with heat insulation strip can reduce energy loss. 4. Protect the environment: Through the application of heat insulation system, energy consumption can be reduced, and the radiation of air conditioning and heating to the environment can be reduced. 5. Noise reduction: The hollow glass structure with different thickness and the hollow structure of heat insulation broken bridge aluminum profile can effectively reduce the vibration effect of sound waves, prevent the sound from spreading, and reduce the noise by more than 30dB. 6. Colorful colors: After surface treatment such as anodizing, powder spraying and fluorocarbon spraying, aluminum profiles with different colors can be produced. Heat-insulated aluminum alloy doors and windows can produce different indoor and outdoor colors after rolling combination.
