Energy-saving aluminum alloy doors and windows features

The doors and windows of a building are part of the external structure of a building and are the most sensitive parts of a building's heat exchange. Its energy consumption per unit area is 5-6 times that of a wall, and the thermal energy loss of doors and windows accounts for more than 40% of the entire building. There are three ways to lose the heat of doors and windows outside the building: first, through the heat conduction loss of the aluminum alloy profile; second, through the radiant heat loss of the glass; third, through the air convection heat loss of the door and window gap. Therefore, the production of insulation and energy-saving aluminum alloy doors and windows must also be considered from these three aspects.

1, aluminum alloy profiles

Aluminum alloy material is a good conductor of heat, and the thermal conductivity is mostly high. To make heat-insulating glass, it is necessary to select the section that has the heat-insulating bridge treatment, that is, to cut off the heat conduction path of the section to achieve the purpose of heat insulation.

2, glass

Insulating doors and windows need to use insulating glass, because the hollow space between the hollow glass filled with dry, static air, so that the thermal conductivity is greatly reduced, so the insulating glass has excellent insulation, sound insulation and frost resistance, condensation Performance, commonly used glass hollow glass thickness 5 ~ 6mm, common cavity thickness 9mm, 12mm.

3, sealing material

Thermal insulation doors and windows with sealant should use weatherproof adhesive, sealant should use anti-ozone corrosion resistance and excellent anti-ultraviolet aging performance of neoprene products, door and window fan opening coincidence part to set more than three seal tape.
