Intumescent Expansion Joint Seal
Our fire-rated expansion joint seals have been designed for use with long linear joint installations in both horizontal and vertical applications where movement may occur. It is flexible and water-resistant and 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 is maintained.
