Fire Performances & Thermal And Acoustic Insulation of MGOTECH Board

Where the Building Code of Australia (BCA) specifies the need for a fire separation system, a level of fire separation needs to be

determined according to the type of structure and the uses on either side of the wall, floor or ceiling structure.

The level of fire separation is expressed by three numbers. For example, 60/60/60 represents –

• The first number indicates that for 60 minutes the wall must continue to carry the design loads. A dash here indicates a nonloadbearing wall

• The second 60 minutes is the time before the wall’s integrity is affected to allow the penetration of hot gases or flames

• The third 60 minutes indicates an insulation failure for allowing too much heat to pass through the wall

Refer to the BCA to determine the fire and acoustic levels required for each application. Fire applications as follows:
