Abesco Fire Rated Movement Joints are designed to prevent the spread of fire from one compartment to another where fire separating walls and floors must accommodate horizontal or vertical movement and provide up to 4 hours fire resistance.

Abesco Fire Rated Movement Joints are made from fire retardant compressible foam, factory coated with a heat reactive intumescent which forms a versatile and flexible gap seal.

What happens in fire

The fire retardant foam provides an effective barrier against the initial passage of smoke. As this foam slowly burns away, the void is filled by the rapidly expanding intumescent, forming an effective seal and preventing the spread of fire, smoke and gases from one compartment to another.
