Description

All expansion and movement joints in a fire separating wall and floor must be fire stopped with a material that will accommodate the require movement whilst providing the necessary degree of fire integrity.

and BS476.

Designed for long linear joint installations in both horizontal and vertical applications it is a flexible and water resistant seal that expands when exposed to heat. The carbonaceous char formed by the graphite prevents the spread of fire through the joint thus ensuring the integrity of the compartment wall/floor is maintained.

Tested with cables, cable bunches, cable trays and cable trunking.
