The Lorient LAS1812LSS Intumescent Fire and Smoke Seal is a dual-function life safety seal designed for rebated door frames, combining cold smoke containment with intumescent fire protection. It helps limit the spread of smoke at ambient temperatures and expands under fire conditions to restrict hot smoke and toxic gases.
