Lorient Finesse Fire & Smoke Intumescent Strip 20x4mm White

Fire Seals Direct works with a number of industry-leading suppliers, and are Lorient's largest distributor. They have a worldwide reputation as a leading manufacturer, and hold third party approval under internationally recognised schemes to the highest standards including IFC and Certifire. 

Intumescent strips, or fire door strips, are fitted to the door, and, when exposed to extreme heat, expand to close any gaps or edges that may leave the fire door vulnerable to fire and smoke spread. The Lorient range of Intumescent Strip range includes a selection of sizes including the wider more traditional solutions. The range accommodates both rebates in single and double action, single or double doors. The seals are ideal for new build applications.
