Acoustic & Fire Single Door Set

The acoustic and fire single door set seals one single fire door against both noise and fire. It combines an intumescent fire and cold-smoke seal around the frame with an automatic drop seal at the threshold, closing every edge of the door when it is shut. The result upgrades a single fire doorset to a smoke-rated, acoustic specification, fitted as part of a complete, tested doorset. Product Highlights Fire, Smoke & Acoustic - one set seals against all three. Intumescent Perimeter Seal - expands in heat to hold back fire. Threshold Drop Seal - closes the gap under the door. Complete Single-Door Set - covers all four edges of one leaf.
