Fire Protection of Ceilings & Floors

The flooring can be of timber or chipboard floor boards supported by either timber or steel joists systems (minimum joist sizes apply). Promat boards are then directly fixed onto these joists in either single or double layer depending on the fire resistance level (FRL) required.

These ceiling are tested or assessed in accordance with AS 1530: Part 4 and achieve the three criteria of structural adequacy, integrity and insulation.
