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.

Made from a elastomeric foam laminated with a graphite-based and a intumescent compound on both sides, it is designed to perform as a 2-hour barrier in construction movement joints when installed correctly.
Tested in accordance with BS 476 Part 20:1987, the intumescent expansion joint seals are ideal for electrical installations and even provide acoustic isolation up to 22 Decibels, each seal measures 1 metre in length.

Please note Some sizes are made to order and can take up to 7-14 working days to be delivered
