High-performance fire-retardant foam, expands 50x. Complies with DIN 4102 & BS476. Ideal for sealing and fireproofing.
The Everbuild Sika Fire Foam B1 Hand Grade is a one-part polyurethane foam with exceptional fire retardant properties. It sets quickly and expands up to 50 times its original volume, making it an efficient solution for fireproofing applications. This foam meets the stringent requirements of DIN 4102 Part 1 (Class B) and BS476 Part 20 (1987), achieving fire ratings from 30 minutes up to 3.5 hours.
