Expansion Joints

Our range of expansion joints are made from fireproof sponge that cars instead of burning, helping prevent fire from spreading through a space. Use these expansion joints between materials in fire walls, ceilings and barriers that are prone to movement, expanding and contracting without compromising a fire barrier.

Gap seals and sponges can also be used around air ducts and ventilation to prevent vibrations, as well as between joists and squeaking floorboards for acoustic and fire protection.

Fire protection doesn’t have to be hard work, let our technical staff help you get the level of protection you require and the finish you want. If there is a product you cannot find, please contact our Technical and Sales Support Team on 0113 245 5450.

For clarification on minimum requirements before buying one of our fire-stopping products, please review the information provided in the 'DATASHEETS' tab on the product in question. A written specification should be obtained from our Technical Department for your project prior to use to ensure the product will be suitable.
