Design of airtight performance of aluminum alloy doors and windows:
The airtight performance of almuniyam window is related to the strength of aluminum alloy doors and windows rod, the sealing effect of rubber strip, the gap of rod connection, the distance between locking points, hardware assembly and processing accuracy.
Air tightness is particularly important in northern engineering because of cold winter.
Plastic window due to the poor strength and rigidity of the profile itself, easy deformation, resulting in serious air leakage, the solution is to increase the number of locking points. In our general design, lock points should be added when the fan height and width are over 1200mm, and the lock point spacing should not be more than 600mm.
