Upgrade timber fire door detailing with this intumescent strip with integral side flipper, designed to deliver a combined fire seal, smoke seal, and acoustic seal for timber door edges and frames. The standout feature is the integral flipper, thermally fused to the rigid box section, helping prevent delamination in normal use and providing a more secure, long-life seal—particularly important where seals pass around or beside door ironmongery.
Supplied in 2.1m lengths with a self-adhesive backing, these fire door seals are quick to install and require no special tools beyond preparing the correct rebate. The streamlined profile improves appearance while also increasing durability and resistance to tampering—an advantage in high-traffic environments such as schools, public buildings and multi-occupancy settings.
