Door and window seals can be divided into three categories in terms of use: glass seals, door leaf door seals and wool tops. Among them, the glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the door frame. The sealing tape is mainly used to seal the gap between the frame and the frame. Therefore, in the installation process of various doors and windows, the sealing strip is indispensable.
