[China Aluminum Industry Network] The heat insulation principle of aluminum alloy doors and windows is to penetrate the insulation strip in the middle of the aluminum profile and break the aluminum profile to form a broken bridge to effectively prevent heat conduction. In general, the thermal conductivity of insulated aluminum alloy doors and windows is reduced by 40 to 70 percent compared to uninsulated aluminum alloy doors and windows.

Heat insulation aluminum alloy doors and windows have the following technical characteristics and advantages:
1, using a separate seal structure, push-pull window with double strip double strip seal structure; flat open window using equal pressure principle, using a hard seal and two soft seal three seal structure, with excellent airtight and watertight .
2, colorful and colorful: the use of anodizing, powder coating surface treatment can produce RAL color 200 different colors of aluminum profiles, after rolling combination, so that heat insulation aluminum alloy doors and windows produce indoor and outdoor different colors of the two-color window .
3, good health: human body and the environment exchange heat depends on the indoor air temperature, air flow rate and outdoor air temperature. By adjusting the interior temperature of doors and windows so that it is not lower than 12 ~ 13 °C, has reached a more comfortable environment.
4, to reduce heat transfer: the use of heat-insulating aluminum alloy profiles, the thermal conductivity of 1.8 ~ 3.5W/m2? K?h is much lower than the ordinary aluminum alloy profiles 140 ~ 170W/m2? K?h; using hollow glass structure, which The thermal conductivity coefficient of 3.17~3.59W/m2?k?h is much lower than the ordinary aluminum alloy profile of 6.69~6.84W/m2?k?h, which effectively reduces the heat conduction through the doors and windows.
5. Preventing condensation: The temperature of the inner surface of the profile with the insulating strip is close to the indoor temperature, which reduces the possibility that the indoor moisture will condense on the surface of the profile due to over-saturation.
6, reduce noise: the use of different thickness of the hollow glass structure and heat insulation aluminum cavity structure, can effectively reduce the acoustic resonance effect, prevent the transmission of sound, can reduce the noise more than 30dB.
7, the use of insulating glass, improve insulation performance and sound insulation effect.
8. Energy saving: In winter, the window frame with thermal 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 thermal insulation strip can More to reduce the loss of energy 9. To protect the environment: Through the application of thermal insulation systems, energy consumption can be reduced, while reducing the environmental radiation due to air conditioning and heating.
