JUHUAN B1 fire rated pu foam oxygen index reaches more than 30%, and it is B1 level meeting the the request of Fire Department of Ministry of Public security and Ministr of Housing. We cooperate with Beijing University of Chemical Technology and spent three years on inventing it, we are first inventor in China. lt passes the test of National Building Materials Testing Center. It is used to seal concealed penetrations from floor to floor or room to room, forms a fire block and a durable. airtight and water-resistant bond. Using this product can cut off way of fire caused by inflammable filler and protect your life and property from the threat of fire.Normal polyurethane foam:In the event of fire, door and window filler will be rapidly ignited and flame quickly flee into the room via the filing accompanied by smoke which causes a great threat to your life and property.JUHUAN B1 fire rated pu foam:When the fire occurs, JUHUAN B1 fire-rated pu foam completely cut off the way which the flame through the filler to spread to win valuable escape time for you .- Sealing gaps around windows, doors, and pipes: PU foam excels at creating airtight seals around these critical areas, effectively blocking drafts and moisture infiltration. Its expansive properties allow it to fill irregular gaps completely, ensuring energy efficiency and preventing water damage. Ideal for both new construction and renovation projects, it enhances thermal performance by eliminating air leaks that contribute to heating and cooling loss.
- Insulating wall cavities, roof spaces, and floor joints: As a superior thermal insulator, PU foam is injected into voids to reduce heat transfer through walls, roofs, and floors. Its high expansion ratio ensures thorough coverage in hard-to-reach areas, improving overall building energy efficiency. Unlike traditional insulation materials, it also provides acoustic dampening, making it a versatile choice for modern construction.
- Filling cracks in concrete, masonry, or wood structures: PU foam bonds seamlessly with these materials, restoring structural integrity by filling cracks and preventing further deterioration. It adapts to environmental changes, resisting shrinkage or expansion, which makes it durable for long-term repairs. This application is crucial for maintaining the aesthetics and safety of historic or aging buildings.
- Fixing leaks in roofs, gutters, and plumbing systems: PU foam acts as a quick-sealing solution for leaks, forming a waterproof barrier that stops water ingress. Its adhesive properties ensure strong bonding to diverse surfaces, preventing recurrent issues. Whether for minor roof patches or plumbing seals, it offers a cost-effective alternative to complex repairs.
- Securing loose tiles, panels, or insulation materials: By expanding to fill voids, PU foam stabilizes loose components, providing immediate support and reducing rattling or movement. It’s particularly useful for securing insulation in attics or wall panels, enhancing both safety and energy efficiency without requiring demolition.
- Sealing cracks in basements, foundations, or driveways: Addressing moisture and structural concerns, PU foam seals cracks in these areas to prevent water penetration and soil erosion. Its flexibility accommodates minor shifts in the foundation, offering a durable solution that extends the lifespan of outdoor surfaces and protects against freeze-thaw damage.
