Thermal insulation aluminum doors and windows production elements

Aluminum windows and doors of buildings is part of the structure outside the building, the building the most sensitive parts of the heat exchange, which is the wall energy per unit area of ​​5 to 6 times the total heat loss of doors and windows of buildings 40% above. Doors and windows outside the building heat loss in three ways: first, through the aluminum alloy heat conduction losses; Second, radiation heat loss through the glass; Third, through doors and windows of the air gap convection heat loss. Thus, the production of thermal insulation aluminum windows and doors from the three aspects should be considered.

1 aluminum alloy aluminum alloy material is a good conductor of heat, the majority of relatively high thermal conductivity. To be made of glass insulation, to choose a thermal bridge processing profiles, namely thermal conduction path blocking profiles, in order to achieve thermal insulation purposes.

Two glass insulation aluminum windows and doors need to use hollow glass, because the cavity between the hollow glass filled with dry, still air, the thermal conductivity greatly reduced, thus insulating glass has excellent heat insulation, sound insulation and anti- Cream coagulation, condensation properties, commonly used insulating glass glass thickness 5 ~ 6mm, common cavity thickness 9mm, 12mm.

3 doors sealing material insulation should be used with sealant weathering plastic, sealing tape should be used in corrosion resistance to ozone and UV aging resistance of neoprene rubber products, doors and windows open fan overlap in part to set three more sealant Article.
