The principle of thermal insulation aluminum alloy doors and windows is that heat insulation strips are inserted in the middle of aluminum profiles to cut off the aluminum profiles to form a broken bridge, which can effectively prevent heat conduction. The thermal conductivity of thermal insulation aluminum alloy doors and windows is 40-70% lower than that of non thermal insulation aluminum alloy doors and windows.
New technical features of thermal insulation aluminum alloy doors and windows
⊙ heat insulation aluminum alloy profile shall be applied. The inner and outer aluminum alloy and heat insulation strip are combined by rolling.
⊙ insulating glass is used to improve the thermal insulation performance and sound insulation effect.
⊙ independent sealing structure is adopted, double rubber strip, double wool and four sealing structure are adopted for sliding window; one hard sealing and two soft sealing three sealing structures are adopted for casement window, which has excellent air tightness and water tightness.
⊙ select high-grade accessories, beautiful shape, flexible operation, safe and reliable, conducive to the heat insulation effect of doors and windows
Advantages of heat insulation aluminum alloy doors and windows
⊙ reduce heat conduction: the heat conduction coefficient of thermal insulation aluminum alloy profile is 1.8 ~ 3.5W / m2 · K · h, which is much lower than 140 ~ 170W / m2 · K · h of ordinary aluminum alloy profile; the heat conduction coefficient of insulating glass structure is 3.17 ~ 3.59w/m2 · K · h, which is much lower than 6.69 ~ 6.84w/m2 · K · h, 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: hollow glass structure with different thickness and heat insulation 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: after anodizing and powder spraying surface treatment, more than 200 types of aluminum profiles with different colors in ral color system can be produced. After rolling combination, the thermal insulation aluminum alloy doors and windows can produce indoor and outdoor dual color windows with different colors.
