Lorient LAS1812LSS Intumescent Fire and Smoke Seal 18x12mm Single Door Set - Black
The Lorient LAS1812LSS Intumescent Fire and Smoke Seal is a dual-function life safety seal designed for installation into door frame rebates. It provides protection against the spread of cold smoke at ambient temperatures and expands under fire conditions to restrict the passage of hot smoke and toxic gases.
This 18mm x 12mm profile is commonly specified for fire-rated door assemblies requiring a discreet, concealed sealing solution. The integrated elastomeric fins deliver effective acoustic and smoke sealing while maintaining low friction door operation.
This configuration is supplied as a Single Door Set (SDS), providing pre-cut lengths suitable for standard single door installations.
