he doors of a building structure , the composition of the external part of 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 more than 40% .
Building windows pvc windows machine is part of the building envelope structure , the heat exchange of the building the most sensitive parts , energy consumption per unit area of the wall 5 to 6 times the total heat loss of doors and windows of buildings 40 % or more. Doors and windows pvc windows machine outside the building heat loss in three ways: first , through the aluminum alloy heat conduction losses ; Second , radiation heat loss through the glass ; thirdly, through the doors and windows of the air gap convective heat loss. Thus, the production of thermal insulation aluminum windows and doors from the three aspects should be considered .
Aluminum extrusions
Aluminum 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.
Glass
pvc windows machine requires the use of insulating glass windows , 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 frost-resistant coagulation, condensation performance, the common thickness of the glass insulating glass 5 ~ 6mm, the common cavity thickness 9mm, 12mm.
Sealing material
pvc windows machine glazing sealant should be used in weather rubber , 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 or more sealing strip . |
