Here you can find intumescent ironmongery protection kits to ensure fire rating compliance for fire doors. We have intumescent lock jackets for our mortice locks and latches and we also have sheet intumescent that can be cut down to size too.
Ironmongery can be CE marked for use on fire doors but without using correct intumescent material with them, they are non-compliant with fire door regulations. Intumescent provides a barrier between the timber in a door and the ironmongery and it expands when it comes into contact with heat to fill in any gaps around it and help to slow down the spread of a fire for a period of time.
It is extremely important, that you choose intumescent with the appropriate fire rating to correspond with the fire rating of the door itself for full fire door compliance.
A universal intumescent kit to suit British Standard deadlocks or Fire Brigade Locks. (Lockcase not included).
