SEALz® Fire & Smoke Seals combine an intumescent fire seal with an additional cold smoke seal to prevent the flow of cold-smoke prior to the activation of the activation of the intumescent fire seal.
The seals comprise a fire seal, as well as a layer of plastic covered by a silicone-treated high-density brush pile. This addition prevents the flow of cold smoke before the intumescent fire seal is activated.
The Fire & Smoke seal is encased in PVC and is typically rebated into door or door frame of smoke control doors.
