Why Hardware Protection Matters

Fire-rated door hardware is essential to the performance of any fire door assembly. When locks, latches, hinges and other ironmongery are rebated into timber doors, material is removed from the door leaf, creating potential weak points.

Metal components can also accelerate heat transfer through the door. In the event of a fire, this can reduce the time it takes for a doorset to reach integrity failure. Intumescent protection is designed to address these risks, helping to maintain the integrity of the complete fire door assembly when it matters most.

Understanding Intumescent Materials

Intumescent materials are specifically developed for fire safety applications. When exposed to high temperatures, the material reacts and expands many times its original volume.

This expansion fills voids around door hardware and helps maintain the structure of the surrounding timber. The resulting char layer acts as an insulator, slowing heat transfer through the fire door. Common solutions include graphite-based intumescent products and Mono-Ammonium phosphate formulations, selected to suit different hardware applications and fire test requirements.
