Intumescent fire door seals fit into a rebate on the fire door or frame. These fire door strips expand to many times the original size and fill the gaps around the door with a flame-tight fire seal for 30 or 60 minutes, depending on the width of the fire seal and your specific requirements. Helping to prevent the spread of fire, this reduces the damage a fire could cause and the risk to life that comes with it, giving everyone plenty of time to evacuate safely.

Where to use intumescent fire door seals

Our fire door seals are commonly found in offices, rental properties, schools, and all other buildings open to the public. For fire safety compliance you should ensure you know which fire rating you require for any intumescent fire door seal you install.

Fire door seal benefits

Each fire door strip is 2.1 metres long and has an adhesive backing which makes the intumescent strips easy to install on your fire door. Available in white or brown, other colours including grey, black, light brown, red or cream can be ordered on request. These fire seals have been fully tested to comply with British Standard 476 Parts 22 and 31.1, and EN1634-3, with Certifire approval. Check out our full range of intumescent strips, including brush fire and smoke seals.

Note - the bulk offer prices give fabulous additional savings for packs of 10 or 150.
 (Strips may be supplied in two 105cm lengths for ease of shipping)
