ã€China Aluminum Network】Aluminum doors and windows with broken bridges, insulated aluminum profiles and insulating glass, with energy-saving, noise, noise, dust, waterproof and other functions. The K value of the broken aluminum doors and windows of Kangying Silent Door and Window Factory is 3W/?·K or less, which is half the heat loss of ordinary windows and doors, reduces heating costs by about 30%, and achieves sound insulation of more than 29 decibels, watertightness and airtightness. Good, all reach the national A1 class window standard. Broken Bridge Aluminum Doors and Windows Advantages and Features 1. Reducing heat conduction: Adopting heat-insertion broken aluminum alloy aluminum alloy profiles, its thermal conductivity coefficient is 1.8-3.5W/?·k which is much lower than that of ordinary aluminum alloy profiles, and the broken aluminum doors and windows are 140-170W/?·k; Hollow glass structure, its thermal conductivity coefficient of 2.0 ~ 3.59W/m2 · k is much lower than the ordinary aluminum alloy profiles 6.69 ~ 6.84W/? · k, effectively reducing the heat transmitted through the doors and windows. 2. Preventing condensation: The temperature of the inner surface of the profile with the insulating strip is close to the room temperature, reducing the possibility that the indoor moisture will condense on the surface of the profile due to over-saturation. 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 4. 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. 5. Health: The exchange of heat between the human body and the environment depends on the temperature of the indoor air, the speed of air flow, and the temperature of the outdoor air. 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. 6. Reduce noise: The use of hollow glass structures with different thicknesses and heat-insulating and broken aluminum profile hollow structures can effectively reduce the resonance effect of sound waves and prevent sound transmission, which can reduce noise by more than 29 dB.
