|About / Description
The Intumescent strip is a graphite-based intumescent fire seal encapsulated in a rigid thermoplastic profile. It has been designed for use in fire resisting door assemblies to seal the gap between leaf and frame, or between separate leaves, in the event of a fire. When subjected to the heat of a fire the intumescent core material expands to fill any gap between the door leaf and frame. This forming of a robust char barrier will hold up the passage of hot gases and smoke as well as the flames.
The Intumescent strip are suitable for use on fire resisting door assemblies manufactured from timber, or timber doors with steel frames. They are unaffected by atmospheric moisture and therefore do not require any further protection.
