Intumescent Fire Door Seal Strip - Fire and Smoke - 15x4x2100mm - Black

Intumescent seals are an essential component of any fire door assembly, designed to maintain the door’s fire integrity by expanding rapidly under heat. These high-performance seals activate in the event of a fire, sealing the gap between the door leaf and frame to prevent the spread of fire, smoke, and toxic gases.

• Tested and Certified: Fully tested to BS 476, these intumescent strips are approved for both FD30 and FD60 fire-rated doors.
• Rapid Expansion Under Heat: The intumescent material reacts quickly to high temperatures, expanding under pressure to close off gaps and resist fire penetration.
• Integrated Smoke Seal: Finished with a brush pile smoke barrier, these seals help block cold smoke from passing through gaps of 2–4mm, enhancing overall protection in early fire stages.
• Suitable for FD60 Installations: For FD60 doors, install two 15mm intumescent seals, spaced so that one seal is not obstructed by hardware such as hinges or locks/latches.
• Self-Adhesive for Easy Fit: Supplied with a strong self-adhesive backing, these fire door seals are easy to apply, saving time during installation while ensuring a secure fit.
