A plain intumescent fire seal measuring 20 x 4 x 2100mm in brown with self-adhesive fixing. The wide 20mm profile provides maximum coverage across the door rebate, suited to doors with larger gaps, heavy-duty commercial applications, or where a wider seal is specified for enhanced fire performance. The intumescent strip expands under heat to seal the gap between door and frame, maintaining fire integrity for the rated period. The brown colour suits timber and wood-effect door frames.

Supplied as a single length of 2100mm.
