Intumescent fire door seals are an essential component in maintaining the integrity and performance of fire doors. They are designed to expand when exposed to heat, minimising the passage of fire and smoke.
- Suitable for gaps of 2-4mm
- When exposed to extreme heat the intumescent will expand at a rapid high pressure speed to contain the fire
- Finished with an optional brush pile smoke screen to prevent any smoke from passing through the door to frame gap
- Completely mineral based meaning it is safe to handle with no fibrous materials or harmful chemicals
- Conveniently made with a self-adhesive backing for ease of application

Are intumescent strips fire rated?
Yes, intumescent strips are fire rated and come in various fire-resistance classes. The fire rating will depend on the type of strip and the application. Ratings typically range from 30 minutes to 2 hours of fire protection.
Strips must be manufactured and tested in accordance with BS476 pt22 and BS EN 1634-1.
What is intumescent material?
Intumescent material expands and forms a dense char when heated or exposed to fire, increasing its volume and decreasing in density. This expansion is called intumescence.
