| Description The sub-division of compartments in a building - if effectively fire stopped - will prevent the spread of fire and smoke through fire resisting and separating elements. All expansion and movement joints in a fire separating wall and floor must be fire stopped with a proprietry material that will accommodate the require movement whilst providing the necessary degree of fire integrity. The ASTROflame Intumescent Expansion Joint Seal is manufactured using various thickness of flame retardant open cellular foam, fire rated to achieve Class 1 and Class 0 when tested to BS476 Part 20. Expandable graphite based intumescent is factory sprayed 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. This carbonaceous char formed by the graphite will prevent the spread of fire through the joint thus ensuring the integrity of the compartment wall/floor is maintained. Areas of Use Between steelwork and blockwork where deflection and movement could occur
