20mm Intumescent fire and smoke seal - brown

Product Information

This intumescent fire and smoke seal is used to maintain the integrity of fire doors in the event of a fire. The 20mm brown seal contains an intumescent material which expands when subjected to heat to form a seal around the fire door, preventing the fire from spreading. The seal also has a brush fitted to it which provides a permanent smoke barrier as smoke travels faster and further than the fire itself.

  • Fully tested to BS476:Part 22 Fire Only and BS476:Part 31:1 cold smoke leakage for the fire and smoke seals
  • Available in white or brown
