What is INTUMESCENT PROTECTION for fire rated ironmongery?

Intumescent protection is thin pieces of material designed to protect the integrity of fire door ironmongery. It fits around (or behind) the hinge, lock, latch etc. and fills the gap between the ironmongery and the door or frame.

Whenever you cut into a door (to fit a lock, hinge etc.) you will have a space where oxygen can hide and reduce the ability of the door to slow the spread of a fire.

Intumescent material is placed into that gap and activates in the event of a fire.

There are two main types of material used

  • Graphite (dark grey, flexible)
  • MAP/Interdens (white, fibrous and rigid)

The material comes in different thicknesses (normally 0.5mm, 0.8mm, 1.0mm and 2.0mm) and which you need will depend on your ironmongery brand and the requirements of your individual fire door.

If in doubt, always ask your fire professional if Intumescent Material is required ans which type you need to buy.
