Suitable for gaps of 2-4mm. When exposed to extreme heat the intumescent has a rapid high-pressure expansion to prevent any fire from spreading. Finished with a brush pile smoke screen to prevent smoke passing through the door frame gap. This intumescent strip has been tested, accredited in the UK and approved use on UK fire doors. Conveniently made with a self-adhesive backing for ease of application
