What are the application ranges of door and window sealing strips? Hongfeng Vehicle answers:

The rubber sealing strips of plastic steel doors and windows play an important role in water tightness, air tightness and energy conservation in doors and windows. According to the function and use requirements of the sealing strip, the plastic steel door and window sealing strip must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, and the sectional structure size shall match with the plastic steel door and window profiles. Plastic steel door and window sealing strips can be divided into glass sealing strips (rubber strips) and wool strips in terms of use. Glass sealing strips are used for sealing between glass and sash and between frames, and wool strips are mainly used for sealing between frames and sashes.

The scope of application of different door and window sealing strips Although the door and window structure is tight and the manufacturing and installation accuracy is high, the door and window sealing strips are still installed on the doors and windows. The various sealing strip series products produced are suitable for different occasions. Some use soft rubber sheets, some use foamed plastic belts, and some are made of chemical fibers and hard plastics. Their elasticity and durability are very good. Some sealing methods are extrusion type, while others are covered by brush. Some fixing methods are self-adhesive, which can be self bonded on the frame and fan; Some are embedded in the reserved slots of doors and windows; Some are fixed with nails. In the final analysis, the types and specifications of the door and window sealing strips used should be compatible with their own doors and windows in order to obtain good results.

The application scope of different door and window sealing strips is different. Some brush or sheet sealing strips are nailed at the door and window joints and can only be used for wooden doors and windows; For the bottom of the door, it is better to use brush or rubber sealing strip; The sealing paste has good bonding performance with metal, can self solidify within 24-28 hours, and its thickness can be adjusted according to the actual needs of the site, which is suitable for metal doors and windows; Some foamed plastic sealing strips with good self-adhesive properties are applicable to windows made of different materials by extrusion sealing method, and their thickness should match the gap width of doors and windows; As for the brush or plastic sealing strip embedded in the slot, it should match with the slot of the door and window.
