Door and window sealing strip
2021-11-05
The door and window sealing strip is divided into three categories: glass sealing strip (rubber strip), door leaf sealing strip and wool strip. The glass sealing strip is used for sealing between the glass and the leaf and the frame. The door leaf sealing strip is mainly used for sealing between the door panel and the door frame, and the wool strip is mainly used for sealing between the frame and the leaf. In the production and installation of plastic steel doors and windows and broken bridge aluminum doors and windows, wooden doors, sealing strip is an essential accessory.
Sealing strip plays an important role in waterproof, sealing and energy saving in plastic steel doors and windows, broken bridge aluminum doors and windows and wood doors and windows, sound insulation, dustproof, antifreeze and warm. It must have strong tensile strength, good elasticity, but also need better 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 must be matched with the plastic steel door and window profile. Sealing strip is generally used for casement doors and windows, hanging windows, folding doors and windows. The main function is dustproof, insect-proof, waterproof, sound insulation, sealing, etc.
The installation part of the wool top is generally on the sliding window (door) leaf, the four surroundings of the frame leaf or on the sealing bridge (wind block) to enhance the sealing between the frame and the leaf. The size of the top is an important factor that affects the performance of sliding doors and windows and water tightness, and it is also an important factor that affects the opening and closing force of doors and windows. The size of the wool top is too large or the bristles are too high, which not only makes the assembly difficult, but also increases the movement resistance of the doors and windows, especially the initial resistance when opening and the final seating resistance when closing. The specifications are too small, or the height of the vertical wool strip is not enough, which is easy to come out of the groove, which greatly reduces the sealing performance of the doors and windows.
There are two kinds of wool strips: siliconized and non-siliconized wool strips. The siliconized wool strips have better effect in use. The qualified wool strips have straight surface, smooth bottom plate and vertical hair, no bending, no pitting on the bottom plate, and conform to the requirement of 0.2mm.
