Are intumescent lock and latch packs required on fire doors?

They are typically required where the fire door manufacturer or fire test evidence specifies them, or where the lock or latch does not include built-in intumescent protection, to maintain the door's FD30 or FD60 rating.

Which kits are available for FD30 and FD60 fire doors?

Bathroom lock, dead bolt, deadlock, DIN lock, sashlock, and tubular latch intumescent kits are available in options suitable for FD30 and FD60 doors, following the relevant fire test evidence.

Can these intumescent kits be retrofitted during maintenance?

Yes. They can be fitted when replacing or upgrading locks and latches on existing certified fire doors, provided the kit aligns with the door and hardware test evidence.

Intumescent Lock and Latch Packs – Certified FD30 & FD60 Fire Door Kits

Upgrade fire door safety with our intumescent lock packs and intumescent latch packs. These kits expand under heat to seal gaps around locks and latches, helping maintain FD30 and FD60 ratings in line with UK regulations.

Essential Fire Door Hardware Protection

Why Every Fire Door Needs Intumescent Lock & Latch Kits

In the UK, FD30 and FD60 fire doors must maintain their integrity in the event of a fire. Fitting a mortice lock or latch removes core material, creating a weak point. Intumescent lock and latch kits expand when heated, sealing gaps to limit fire and smoke spread.

These kits are essential for:

Joiners and carpenters fitting fire doors.
Contractors on new builds and refurbishments.
Facilities teams maintaining commercial or residential buildings.

Our range includes Bathroom Lock Intumescent Kits, Dead Bolt Intumescent Kits, Deadlock Intumescent Kits, DIN Lock Intumescent Kits, Sashlock Intumescent Kits, and Tubular Latch Intumescent Kits — all tested to BS 476 and BS EN 1634.

For a complete project solution, pair with Architectural Ironmongery, Door Furniture, and Fire Door Acoustic Seals.
