What should be paid attention to when making aluminum alloy doors and windows? There are three ways of heat loss of aluminum alloy doors and windows outside buildings: firstly, the heat conduction loss through aluminum alloy profiles; secondly, the radiation heat loss through glass; finally, the air convection heat loss through the gap of aluminum alloy doors and windows. Therefore, heat preservation and energy-saving aluminum alloy doors and windows should also be considered from these three aspects.

1. Aluminum alloy profiles

Aluminum alloy profiles and aluminum alloy materials are good thermal conductors with high thermal conductivity. If we want to make thermal insulation glass, we must choose the profile which has been treated by thermal insulation bridge. Its function is to cut off the heat conduction path of the profile, so as to achieve the purpose of thermal insulation.

2. Glass

For the glass of aluminum alloy doors and windows, it is necessary to use insulating glass, because the cavity between the insulating glass is filled with dry and static air, which greatly reduces the thermal conductivity. Therefore, in addition to the function of sound insulation and heat insulation, it also has the functions of energy saving, safety and anti fog. The glass thickness of commonly used insulating glass is 5 ~ 6mm, and the common cavity thickness is 9mm, 12mm.

3. Door crack

For aluminum alloy doors and windows with thermal insulation materials, weather resistant sealant shall be selected as sealant, chloroprene rubber products with excellent ozone corrosion resistance and ultraviolet aging resistance shall be selected as sealant strips, and more than three sealant strips shall be set at the opening and overlapping parts of door and window leaves.
