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.

Astroflame Intumescent Expansion Joint Seal is an elastomeric foam laminated with a graphite-based, intumescent compound on both sides. It is designed to perform as a fire barrier in construction movement joints, when tested to EN 1366-4 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 in block wall, concrete and masonry. Tested in concrete floors. Tested in linear joints up to 150mm wide.

Joint movement capability of +/- 50%.

Maintenance free.
