Although the rubber strip is small, it has a powerful effect

As a necessary accessory for door and window systems, the cost of sealing strips only accounts for 3% to 5% of the door and window system, but their sealing effect accounts for 50% to 70%. It can be said that the key to the quality of doors and windows lies in the adhesive tape.

Six major functions: waterproofing; Dust prevention; Sound insulation; Temperature insulation; shock absorption; Collision avoidance. Sealing strips are installed on door and window frames, sashes, and glass, relying on their elastic properties to seal the gaps between door and window profiles, hardware, and glass, and tightly connect them into a whole. They play an indispensable role in improving the air tightness, water tightness, sound insulation, and energy-saving performance of doors and windows.

The heat loss of unsealed doors and windows is 5-6 times that of walls. The insulation and air tightness performance of doors and windows play an extremely important role in energy conservation and consumption reduction in buildings.
