LY profile KO sealant strip

Door and window sealing strips can be divided into glass sealing strips (adhesive strips) and wool strips in terms of use. Glass sealing strips are used for sealing between glass and leaf and between frames, and wool strips are mainly used for sealing between frames and leaves Sealant strips are generally applied to the sealing between casement windows and top hung windows, as well as between sash and glass of casement windows and sliding windows; Sealing wool is generally used for sealing and dust-proof between sliding windows In the production and installation of plastic steel doors and windows and bridge cutoff aluminum doors and windows, a necessary accessory is the sealing strip.

There are many specifications of sealant strips. The common ones on the market are O, K, P and KO. The latest KO process sealant strips are used for LY profiles.

Door and window sealing strips play an important role in waterproof, sealing and energy saving in plastic steel doors and windows and bridge cutoff aluminum doors and windows, sound insulation, dust prevention, antifreeze and warmth preservation KO type sealant strip has strong tensile strength, good elasticity, and good temperature resistance and aging resistance.

Plastic steel doors and windows are most prone to air leakage in windy days, and the sealing effect of KO adhesive tape is precisely aimed at such windy days to prevent doors and windows from whistling.
In order to ensure the fastening of the rubber strip and the profile, the sectional structure size of the door and window sealing strip must match the plastic steel door and window profile The installation position of the wool sliver is generally on the window (door) leaf, the perimeter of the frame leaf or the sealing bridge (wind deflector) to enhance the sealing between the frame and the leaf The specification of wool top is an important factor affecting the watertight performance of sliding doors and windows, as well as the opening and closing force of doors and windows If the specification of wool top is too large or the vertical wool is too high, it is not only difficult to assemble, but also increases the moving resistance of doors and windows, especially the initial resistance when opening and the rear positioning resistance when closing The specification is too small, or the height of the vertical wool is not enough, which is easy to come out of the groove. The sealing performance of the door and window sealing strip is greatly reduced The wool top shall be subject to silicification treatment. The qualified wool top shall have straight surface, smooth base plate and vertical hair without bending, and no pitting on the base plate, meeting the requirements of 0.2mm.
