Ironmongery Protection
Ironmongery protection is a critical part of the wider fire stopping strategy in any building where fire safety is a design priority. These systems work by helping ensure that openings created by hinges, handles, locks, latches, and other hardware do not compromise compartmentation in the event of a fire. Fire-rated ironmongery is required to resist high temperatures, protect escape routes, and support the overall fire integrity of door assemblies, shutters, or glazed systems. Ironmongery protection may also form part of an upgrade to existing fire-rated doors where door integrity must be preserved across hardware locations.

Fire-Rated Ironmongery Protection for Doors and Structural Openings
Ironmongery protection plays an essential role in fire compartmentation by ensuring that door hardware maintains integrity during a fire. It is used with door upgrade kits where existing or historic doors require improved fire performance. These kits often incorporate compatible intumescent components around locks, hinges, and other hardware to help preserve the door's fire-resisting function, especially in heritage or listed buildings where full replacement is not viable.
Products in this category are assessed as part of a door assembly or tested in combination with specific materials, such as hardwoods or MDF, to determine their contribution to fire resistance. They must resist high temperatures without compromising the stability of the fire-rated door or the spread of smoke. Guidance recommends that these systems are selected based on comprehensive fire testing and, ideally, backed by third-party certification. When properly specified and installed, protected ironmongery helps meet requirements for integrity and insulation at key junctions, such as door-to-frame interfaces or latch and closer fixings.
Ironmongery Protection FAQs
Can ironmongery protection be retrofitted to existing fire-rated doors?
Only if the full door and hardware assembly has been tested or assessed for upgrade. The exact specification must match test data.
Do hinges and locks need to be fire rated?
Yes. All hardware installed in a fire-rated door must be capable of withstanding fire conditions and tested for compatibility with the full door leaf.
How do ironmongery protection kits relate to fire seals?
They often work together. Intumescent kits are installed around hardware cut-outs while fire seals are fitted at the edges to prevent smoke ingress.
Is third-party certification required for ironmongery protection?
While not legally required, it is strongly recommended. Certification confirms consistent performance and manufacturing quality.
Can I use the same ironmongery protection across timber and composite doors?
No. Each material responds differently in fire, so the product must be tested for the specific door type and construction.
