DS Acoustic Seal, Smoke Seal & Fire Door Seal
Dual seal (DS) is designed to allow seal continuity at hinge positions.
This slim high performance intumescent fire and smoke seal is designed to upgrade existing door assemblies that are required to restrict the passage of medium and hot temperature smoke. The dual flexible fins retard the spread of smoke and when exposed to elevated temperatures the intumescent core rapidly expands in volume to restrict the passage of fire, hot smoke and toxic gases.
