Description:
BILIN S3 Spray PU Foam delivers superior thermal insulation with rapid-setting polyurethane technology, forming a seamless, high-performance barrier upon application. Its porous closed-cell structure minimizes heat transfer, while exceptional adhesion ensures airtight seals on wood, metal, concrete, brick, and even expanded polystyrene substrates. Designed for roofs and walls, it eliminates thermal bridges by creating a continuous insulation layer, significantly boosting energy efficiency. The eco-friendly, CFC-free formula cures quickly into a stable, durable finish, enabling efficient large-area coverage with minimal material waste. As a thermosetting polyurethane, BILIN S3 combines lightweight ease of application with industrial-grade thermal resistance, making it a versatile solution for modern construction needs.
