Linear Gap Seal (intumescent)

Product Description:

Expansion and movement joints in a fire compartment wall and floors must be fire stopped with a material that will accommodate the require movement whilst providing the necessary degree of fire integrity.

Intuchem Linear Gap Seal is manufactured using various thickness of flame retardant open cellular foam an expandable graphite based intumescent is factory laminated onto both sides of the foam, forming a compressible fire resistant joint filler which is resistant to moisture attack.

The graphite based material starts to intumesce around 115°C on the fire side of the joint whilst the fire rated foam gradually compresses allowing the expanding mass of intumescent graphite to totally seal the opening.

A char is formed by the graphite that will prevent the spread of fire through the joint thus ensuring the integrity of the compartment wall/floor is maintained.

Use between steelwork and blockwork where deflection and movement could occur and in movement joints with blockwork walls and floors.

To the top of wallhead to the underside of the floor, gaps may well be uneven so Intuchem linear gap seal is extremely compressible and should accommodate any irregularities.

Performance temperature between -30 to +130°c
2hr and 4hr rated seal types available at the online shop.
