Compressible fireproof sponge strips with foil-clad intumescent material on one or two sides, for use as movement or expansion joints. They are easy to install and unaffected by water or chemicals.


– Extremely versatile, providing up to 240 minutes protection in a range of applications, for example:- As movement or expansion joints in fire walls, floors, concrete slabs and steelwork
– As a cavity joint between brickwork and timber structures
– Around ventilation ducting as a movement and anti-vibration joint
– As a seal over the tops of cable trays passing through protected building elements

Application Instructions

Made in a range of sizes to suit gaps up to 120mm wide, the expansion joints are easily installed giving
protection to both horizontal and vertical gaps. Simply compress into narrow gaps or apply to one side
of a wider gap, using double sided tape on one face to adhere in place. The sponge and intumescent
expansion joint allows for movement but, in the event of a fire, will completely fill the gap.
