Common knowledge about sealing strips

Dec 10,2024


The use of sealing strips in the construction of doors and windows is necessary to achieve a sealed closure between the profiles and the glass, as well as between the sash and the frame. Sealing strips play a role in fixing the glass, buffering vibrations, and blocking water and air flow in door and window applications. The thermal insulation and air-tightness of doors and windows have a significant impact on the energy conservation and consumption reduction of buildings. Poorly sealed doors and windows can result in heat loss that is 5-6 times greater than that of the walls. The energy efficiency of doors, windows, and curtain walls accounts for about 37-40% of the overall building energy savings. Therefore, sealing strips are an essential functional accessory in the energy efficiency of doors and windows, and their performance and lifespan should be given due attention.
