Building doors and windows sealing strip plays an important role in waterproof, sealing and energy saving in plastic steel doors and windows, broken bridge aluminum doors and windows, wood doors and windows. They are soundproof, dust-proof, freeze-proof and warm. Building door and window sealing strip has strong tensile strength, good elasticity, and good temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structure size of the rubber strip should match the plastic steel door and window profile. Sealing strip is generally used for side hanging doors and windows, hanging windows, folding doors and windows. The main functions are dustproof, insect-proof, waterproof, sound insulation, sealing, etc.

The top-mounted building door and window sealing strip is generally located around the sliding window (door) leaf, frame leaf or on the sealing bridge (wind block) to strengthen the seal between the frame and the leaf. The top specification is an important factor affecting the performance and water tightness of sliding doors and windows, and it is also an important factor affecting the opening and closing force of doors and windows. Too large top or too high vertical hair will not only make assembly difficult, but also increase the resistance of doors and windows, especially the initial resistance when opening and the resistance when closing. If the specification is too small, or the height of the standing roof is not enough, it is easy to fall out of the groove, which greatly reduces the sealing performance of the doors and windows.

There are two types of building door and window sealing strips: siliconized and non-siliconized. The silicided top is more effective in use. Qualified building door and window sealing strips have a straight surface, smooth bottom plate and vertical bristles, no bending, and no pits on the bottom plate, in accordance0.2mm specified.
