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.
