Fire Resistance Minutes
Provides 60 to 120 minutes (1 - 2 hours) for standard load-bearing structural runs, and up to 240 minutes (4 hours) for non-load-bearing internal partitions.
H+H's Celcon Blocks High Strength Grade (7.3N/mm2 identified with a black stripe on the block) is ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.

Class A1
Fire Resistance Minutes
Up to 120 minutes (2 hours) for load-bearing, and up to 240 minutes (4 hours) for non-load-bearing 100mm structural wall systems.
Coursing Units are produced from the same material as all H+H aircrete and are suitable for the same applications as conventional size Celcon Blocks, allowing consistency within the building fabric.
