The broken aluminum doors and windows are insulated with broken bridges, aluminum profiles and insulating glass. They have the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproof. The heat conduction coefficient K comwin mute doors and windows factory aluminum doors and windows of the value of 3W/ square meters, below K, than the ordinary windows heat loss is reduced by half, reducing heating costs about 30%, amounted to more than 29 decibels of sound insulation, water tightness, good air tightness, reached the national standard A1 window class.

 　　Advantages and characteristics of broken aluminium aluminum doors and windows

　　1. the lower the heat conduction insulation bridge Aluminum Alloy profiles, the heat conduction coefficient is 1.8 ~ 3.5W/ square meters K is much lower than that of normal Aluminum Alloy profiles, aluminum doors and windows 140 square meters K ~ 170W/; the use of hollow glass structure, the heat conduction coefficient is 2 ~ 3.59W/m2 / K is much lower than that of normal Aluminum Alloy profiles 6.69 ~ 6.84W/ m - K, effectively reducing the heat conduction through the doors and windows.

　　2. prevent condensation: the temperature of the inner surface of the profiles with insulation bars is close to the indoor temperature, reducing the possibility of condensation of the interior moisture on the surface of the profiles.

　　3. in the winter, with energy-saving insulation window can reduce the heat loss of the 1/3 through the window; in the summer, if it is in the air, with the window frame insulation can do more to reduce the loss of energy

　　4. protect the environment: through the application of heat insulation system, can reduce energy consumption, while reducing the air conditioning and heating caused by environmental radiation.

　　5. good health: the heat exchange between the human body and the environment depends on the temperature of the indoor air, the speed of the air flow and the temperature of the outdoor air. By regulating the indoor temperature of doors and windows, so that it is not less than 12~13 degrees centigrade, it has reached the most comfortable environment.

　　6. reduce noise: the use of different thickness of insulating glass structure and insulation of aluminum broken bridge cavity structure, can effectively reduce the acoustic resonance effect, to prevent the transmission of sound, noise can be reduced by more than 29dB.
