The principle of heat insulation bridge breaking aluminum alloy is to insert heat insulation strip in the middle of aluminum profile to cut off the aluminum profile to form a broken bridge and effectively prevent heat conduction. The thermal conductivity of Lifan thermal insulation aluminum alloy doors and windows is 40-70% lower than that of non thermal insulation aluminum alloy doors and windows.
⊙ reduce heat conduction: the heat conduction coefficient of heat insulation bridge breaking aluminum alloy profile is 1.8 ~ 3.5W / m2 · K, which is much lower than 140 ~ 170W / m2 · K of ordinary aluminum alloy profile; the heat conduction coefficient of insulating glass structure is 2.0 ~ 3.59w/m2 · K, which is much lower than 6.69 ~ 6.84w / m2 · K, which effectively reduces the heat conduction through doors and windows.
⊙ prevent condensation: the temperature of the inner surface of profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of indoor moisture condensation on the profile surface due to supersaturation.
⊙ energy saving: in winter, the window frame with heat insulation strip can reduce 1 / 3 of the heat loss through the window frame; in summer, if there is air conditioning, the window frame with heat insulation strip can reduce the energy loss more
⊙ environmental protection: through the application of heat insulation system, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced.
⊙ beneficial to health: the heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows to make it no less than 12 ~ 13 ℃, the most comfortable environment has been achieved.
⊙ noise reduction: the hollow glass structure with different thickness and heat insulation bridge broken aluminum profile cavity structure can effectively reduce the resonance effect of sound wave, prevent the transmission of sound, and reduce the noise by more than 30dB.
⊙ colorful colors: aluminum profiles of different colors can be produced after anodizing, powder spraying and fluorocarbon spraying surface treatment. After rolling combination, the thermal insulation aluminum alloy doors and windows can produce indoor and outdoor dual color windows with different colors.
