Choosing the Right Intumescent Seal
FD30 vs FD60 | Widths, Fitting & UK Standards
Intumescent fire door strips are a core element of passive fire protection. For FD30 doors, choose 10mm or 15mm widths; for FD60, select 20mm. These fire‑only intumescent strips expand rapidly under heat to seal the perimeter gap and help maintain compartmentation. They’re typically routed into the door leaf (two vertical edges and the head), and must be fitted in line with manufacturer guidance and UK test evidence (e.g. BS 476 or BS EN 1634).
Popular searches we support include FD30 intumescent seals, FD60 intumescent seals, fire door edge seals, heat‑activated door seal, fire door gap sealing strip and fire rated door seal strip. Colour‑match in white, brown or black for a discreet finish. For full door assemblies, explore: Fire & Acoustic Seals (parent), Door Closers, Intumescent Hinge Packs, Intumescent Lock & Latch Packs and Intumescent Letter Plates.
