When choosing a sealing strip, the following points can be considered:
Smell: High quality PVC material may have a slight mellow smell. If a strong odor is found in the sealing strip, it indicates poor quality.
Pull by hand: Pull the sealing strip hard, the higher the adhesive content, the better the quality. If it breaks immediately upon tearing, it indicates poor quality.
Scratching with nails: Poor quality sealing strips are prone to scratches, and insufficient surface brightness also indicates poor quality.
The function and installation precautions of sealing strips:
The sealing strip has a significant impact on the air tightness, water tightness, wind pressure resistance, sound insulation, and thermal insulation performance of aluminum alloy windows. When installing, it should be embedded in place, with a flat surface and close contact with the glass and glass groove, so that the force around the glass is evenly distributed. The rubber sealing strip should not be pulled too tightly, and the cutting length should be 20-30mm longer than the assembly length.
