Fire Doors – Understanding Building Code requirements for fire doors

Posted by Stroeven

Clause C3 Spread of Fire of the Building Code requires fire separations. These fire separations must perform as required in order for the building to provide adequate passive fire resistance, thereby allowing the building to function safely in a fire emergency.

The fire resistance must be complete across the fire or smoke separation. All components that form part of that separation must be capable of achieving the required fire or smoke (or both) resistance required for the doorset within the separation. Therefore, any door or window installed in the separation must have an appropriate resistance to fire, smoke or both.

Any breaches through the separation (including through the doors) must be fire or smoke-stopped (or both) to retain the required rating of the separation.
