Sealing strip in the steel doors and windows and broken Bridge aluminum doors and windows and wooden doors and windows played a waterproof, sealing and energy-saving important role, sound insulation, dustproof, antifreeze, warm. It must have a strong tensile strength, good elasticity, but also a better temperature resistance and anti-aging properties. In order to ensure the fastening of the rubber strip and the profile, the section structure size of the strip must be matched with the steel door and window profiles. Sealing strips generally use flat open doors and windows, hanging windows, folding doors and windows. The main role is dustproof, pest control, waterproof, sound insulation, sealing and so on.
Top of the installation site is generally in the sliding window (door) fan, the box fan around or seal bridge (file wind block), enhance the box and the seal between the fan. The top specification is an important factor affecting the push-pull doors and windows and the water tightness, as well as the influence of door and window switching force. Top specifications too large or too high, not only difficult to assemble, but also to increase the door and window movement resistance, especially when the initial resistance and closing when the final position resistance is greater. Specifications too small, or the height of vertical tops, easy to get out of the groove, so that the door and window sealing performance greatly reduced.
