DS Acoustic Seal, Smoke Seal & Fire Door Seal
Dual seal (DS) is designed to allow seal continuity at hinge positions.
This slim-line, dual function seal is fitted to door frames to restrict the spread of ambient and elevated temperature smoke. When exposed to fire conditions the intumescent core rapidly expands in volume to restrict the passage of hot smoke and toxic gases.
