Each Fire and Smoke Intumescent Strip is manufactured to meet or exceed industry standards such as BS 476 Part 22 and EN 1634, ensuring complete compliance for contractors working on regulated projects. The material expands rapidly when exposed to heat, sealing the door perimeter to restrict the transfer of flames and toxic gases.

With convenient prepack options and consistent quality across batches, our strips deliver cost efficiency and reliability for long-term contracts.
Durable and Easy to Install
Each 4mm strip features a self-adhesive backing for quick installation on timber, steel, or composite doors. The high-adhesion tape ensures a strong bond while allowing minimal downtime during fitting. For volume projects, the consistent sizing reduces waste and speeds up assembly line operations.
