Sealing of Aluminum Alloy Door and Window Frames and Sashes
There are mainly three parts that need to be sealed in finished aluminum alloy doors and windows, namely, the seal at the connection between the door and window frame and the wall, the seal between the door and window frame and the sash, and the glass seal
1 - Sealing at the connection between the door and window frame and the wall; 2 - Sealing between the door and window frame and the sash; 3 - Glass sealing. This article mainly introduces the sealing forms between the door and window frames and sashes. The sealing of the door and window frames and sashes refers to the sealing between two door and window frames and sashes with relative motion, and its sealing quality should meet the requirements for the air - tightness, water - tightness, heat - insulation performance, and sound - insulation performance of the doors and windows. There are three common sealing forms between alloy door and window frames and sashes as follows: (1) Intermediate sealing is implemented in the inner space of the door and window frame and sash (Figure 2). (2) Frame - edge sealing is implemented on the inside or outside of the frame edge between the alloy door and window frame and sash
(3) Frictional sealing is used to seal the gaps of two parallel and corresponding components, such
Frictional sealing is generally used between two narrow gaps of planes and is sealed with wool strips or rubber strips. For sliding doors and windows sealed in this way, they can be pushed left and right. The pressure on the sealing wool strips or rubber strips should not be too great; otherwise, the door and window sashes may not be able to be pushed.
