Fire & Smoke Seal, 20mm x 1050mm, White (ISS20/W/1050)

Product Description

This intumescent fire and smoke seal is used to maintain the integrity of fire doors in the event of a fire. The 20mm white 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.
