HENSOTHERM® 820 KS

HENSOTHERM® 820 KS improves the fire-resistance time of pre-stressed concrete hollow ceilings up to 120 minutes, that of reinforced concrete beams and supports up to 150 minutes, and that of concrete flat slab ceilings and reinforced concrete ribbed slab ceilings up to 240 minutes. In the event of fire, HENSOTHERM® 820 KS forms a heat-insulating barrier of carbon foam and thus prevents the concrete structural elements from heating up and the concrete from flaking off the steel reinforcement – patented under European Patent No. 2686391.
