Description:
BILIN S3 Spray PU Foam offers fast, broad-coverage application for sealing gaps, joints, and irregular surfaces on walls and roofs. Its specialized nozzle ensures efficient, uniform spraying, even in tight spaces, forming a durable, moisture-cured insulation layer with high adhesion. The porous polyurethane structure delivers outstanding thermal resistance, effectively blocking heat transfer and reducing energy loss. Compatible with wood, metal, concrete, and EPS, it creates airtight, water-resistant seals while being environmentally friendly (CFC-free) and enhancing long-term energy efficiency.
