The sealant used for thermal insulation doors and windows shall be weather resistant, the sealant strip shall be chloroprene rubber products with excellent ozone corrosion resistance and ultraviolet aging resistance, and more than three sealant strips shall be set at the opening and overlapping part of door and window leaves.
The energy consumption per unit area is 5-6 times of that of the wall, and the heat loss of the doors and windows accounts for more than 40% of the total aluminum doors and windows.
What are the heat loss ways of Shanghai window and door materials?
There are three ways of heat loss in the external doors and windows of bridge broken aluminum doors and windows: firstly, the heat conduction loss through the broken bridge aluminum profile; secondly, the radiation heat loss through the glass; thirdly, the air convection heat loss through the gap between the doors and windows. Therefore, Shanghai liefan decoration materials Co., Ltd. warm tips: the production of thermal insulation broken bridge aluminum doors and windows should also be considered from these three aspects.
1. Bridge breaking aluminum profile
Bridge broken aluminum material is a good thermal conductor with high thermal conductivity. In order to make thermal insulation glass, it is necessary to select the profile with heat insulation bridge treatment, that is, to cut off the heat conduction path of the profile, so as to achieve the purpose of thermal insulation.
Insulation doors and windows need 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, the insulating glass has excellent heat insulation, sound insulation, frost resistance and condensation resistance. The glass thickness of commonly used insulating glass is 5-6mm, and the common cavity thickness is 9mm and 12mm.
