Do I need Intumescent Protection?
WHAT is Intumescent Hardware Protection?
Intumescent is material designed to expand in the event of a fire. It is part of 'Passive Fire Protection' in that it does not activate until it is exposes to the extreme heat of a fire and activates automatically.
HOW does Intumescent Hardware Protection Work?
It fills the gaps to reduce air flow and slow down the progress of the fire.
WHY is Intumescent Hardware Protection so important in Fire Doors?
Because, without it fitting a piece of ironmongery (hinge, lock, latch etc.) leaves small air gaps in the structure of the fire door.
These gaps (although very small) allow air to 'feed' the fire and weaken the integrity (structure) of the door.
