PU Foam Application for Doors and Windows

During door and window installation, PU foam plays a key role in sealing and securing.
Once the frame is adjusted to the proper position and fixed, installers evenly inject PU foam into the gap between the frame and the wall.
After application, the foam expands rapidly to tightly fill the gap, effectively preventing air leakage and water infiltration. Once cured, it firmly secures the frame in place while enhancing sound insulation and thermal performance.
On-site, the smooth dispensing, uniform expansion, and quick curing of PU foam make door and window installation more efficient and aesthetically pleasing, ensuring long-term sealing performance and a comfortable indoor environment.

Application Advantages:

1.Waterproof Sealing – Prevents rainwater from seeping through gaps, avoiding dampness and mold.

2.Sound & Heat Insulation – Blocks outside noise and reduces heat loss.

3.Strong Support – Strengthens the bond between the door/window frame and the wall.

4.Easy Application – Simple operation, fast curing, and improved installation efficiency.
