Wooden Fire door Seal Fire and Smoke (Double Flipper Co extruded) – Graphite

Price Range : Rs. 215 – Rs. 400
(7 ft Strip)

Intumescent fire, smoke and acoustic seal

Our co-extruded Flexifin seals provide an integrated solution to problems of fire spread, cold smoke leakage, and acoustic insulation. Available in both centered and off-centered designs, Flexifin not only offers highly effective sealing but also allows doors to return to their closed position with minimum resistance.

Often preferred in certain environments to the standard brush pile, these seals provide greater acoustic sealing performance and are ideally suited to hospitals, clean rooms, computer rooms, or food preparation areas.

The fin blades are made from high-performance thermoplastic, fused to a rigid PVC holder in the manufacturing process, containing either our 500 or 100 intumescent material.

Fire tested to BS 476: Part 22: 1987 and smoke tested in accordance with BS 476: Part 31: 1987.
