Intumescent Protection for Fire Door Ironmongery

Keep your fire doors fully compliant by specifying the right intumescent protection. This covers products for use with locks, latches, hinges, and door hardware. These items play a critical role in passive fire safety. They shouldn’t be an afterthought during specification or installation.

Ironmongery tested for use on fire doors can lose its certification if fitted without the correct intumescent materials. Adding protection jackets, sleeves, pads, and intumescent packers supports test evidence and helps maintain the fire resistance of the door set.

Why Use Intumescent Ironmongery Protection?

Intumescent materials expand rapidly under heat, filling gaps around ironmongery and slowing the spread of fire and smoke. They help maintain compartmentation for the duration of the fire door’s rating, usually 30 minutes or 60 minutes. Without the appropriate protection in place, a compliant fire door can become non-compliant and lose its integrity.

Different types of intumescent material react differently when exposed to heat. This could be its direction, pressure, activation temperature, or volume of expansion.

So, check the test evidence and choose:

• Graphite
• MAP (mono ammonium phosphate)
• Sodium silicate
• Trademarked products like Interdens intumescent

Never mix and match types of intumescent strips, fire seals, or intumescent packs.

Protection that Reacts in the Heat

• Intumescent lock sleeves and jackets for gap-filling in lock and latch mortices
• Pre-cut fire kits for installation in concealed fire door closer cut-outs
• Intumescent sheets and strip are a flexible solution where bespoke protection is required

Correctly fitted intumescent components work with the door, frame, and fire door hardware to hold back flames and smoke. This provides crucial time for safe evacuation or fire rescue service intervention.

Compatible with a Range of Door Hardware

This range supports the installation of a wide variety of certified ironmongery, including mortice locks, latches, hinges, and other door furniture.

Suitable products include:

• Intumescent lock protection kits – complete sets for mortice locks and latches
• Intumescent lock jackets and sleeves – use with fire rated digital keypad door locks
• Fire rated kits and packs - for ancillary hardware like flush bolts and door viewers
• Intumescent hinge plates and hinge pad sets – sized for popular fire door hinge types, plus concealed hinges and conductor hinges

Whether you're installing new hardware or replacing existing, adding the right passive fire protection supports full certification, building regulations, and fire safety best practices.

For Use on FD30 and FD60 Fire Doors

A CE or UKCA mark on hardware doesn’t guarantee fire door compliance on its own. Each intumescent hinge pad, lock kit, or sleeve must match the rating of the door and hardware it is used with. Using the wrong thickness or incorrect type may lead to non-compliance and invalidate test evidence.

Before ordering, check the test data supplied with the fire rated door and your chosen mechanical or electric lock, door closer, or hinge. Many items specify exact protection requirements, including:

• Sheet thickness
• Pad or packer configuration
• Material type, such as graphite or Interdens
