What are the characteristics of broken bridge aluminum doors and windows in Wuhan?

Broken bridge aluminum doors and windows, using heat insulation broken bridge aluminum profiles and insulating glass, have the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproof. The thermal conductivity K value of the broken aluminum doors and windows is below 3W/㎡ k, which reduces the heat loss by half compared with ordinary doors and windows, reduces the heating cost by about 30%, and the sound insulation capacity is above 29 dB, and the water tightness and air tightness are good, all reaching the national A 1 class window standard.

Reduce heat conduction: the heat conduction coefficient of aluminum alloy profile with thermal insulation broken bridge is1.8 ~ 3.5 w/m2 k, which is much lower than that of ordinary aluminum alloy profile140 ~170 w/m2 k; The insulating glass structure is adopted, and the thermal conductivity is 2.0 ~ 3.59 W/m2 k, which is much lower than that of the ordinary aluminum alloy profile, which is 6.69 ~ 6.84 W/m2 k. Breaking aluminum doors and windows can effectively reduce the heat conducted through the doors and windows.

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 surface of the profile due to oversaturation.

Energy saving: in winter, the window frame with heat insulation strips can reduce the heat lost through the window frame1/3; If there is air conditioning in summer, the window frame with heat insulation strip can reduce energy loss.

Environmental protection: 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. Good for health: The heat exchange between human body and environment depends on indoor air temperature, airflow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows not lower than 12 ~ 13℃, the most comfortable environment is achieved.

Noise reduction: The hollow glass structure with different thickness and the hollow structure of heat insulation broken bridge aluminum profile can effectively reduce the resonance effect of sound waves, prevent the spread of sound and reduce the noise by more than 30dB.

Colorful colors: After surface treatment such as anodizing, powder spraying and fluorocarbon spraying, aluminum profiles with different colors can be produced. After the heat-insulating aluminum alloy doors and windows are combined by rolling, indoor and outdoor double-color windows with different colors can be produced.
