LAS1812 LSS intumescent fire & smoke seal

This slim-line, dual function life safety 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.

Key benefits

  • All-in-one “life safety” seal. Ideal for use in fire engineering solutions to limit the spread of fire, ambient, medium and hot temperature smoke around the edges of doors.
  • Easily retrofitted to existing door assemblies.
  • Dual sealing fins accommodate significant door deflection to maintain effective sealing performance.
  • Dual low friction curved elastomeric fins provide outstanding acoustic performance.
  • Discreetly positioned in frame rebate to provide a fully concealed sealing solution.
  • Simple peel-and-stick installation, our aggressive self-adhesive backing is tested on many surfaces to ensure seal longevity. 
  • Seal surface and fins contain anti-microbial additives torestrict bacterial growth.
