The main reason why doors and windows leak air and rain
Frame and sash matching problems
The window frames and sash of doors and windows are sealed by overlapping. The overlapping part of the sash and frame is called the overlap amount. Due to the size deviation of the window frame and sash, straightness deviation of the window frame installation will cause the actual overlap amount of the window frame and the window sash to change. When the overlap amount of the frame and sash increases, the gap between the frame and sash will decrease, which will make installation difficult in severe cases;
When the frame When the overlap amount of the sash is reduced, the sealing performance will be reduced. If the overlap amount is too small, the risk of the door and window falling off will increase.
The sealing strips are aging and falling off
There is a big difference in the price of the sealing strips between good doors and windows and cheap doors and windows! Cheap doors and windows generally use low-quality sealing strips, and you will know the tricks after using them for a while.
The adhesive strips of poor quality have poor aging resistance. After being exposed to the sun for a long time, the adhesive strips will harden after aging, lose elasticity, and fall off easily. Not only does the sealing performance be poor, but the glass will loosen and cause safety hazards.
