External Fire Rated Walls - FRL 30/30/30 or FRL 60/60/60

Refer directly to lining manufacturers for specification of plasterboard type, thickness and grade and weather protection to the plasterboard.

Details below are indicative methods only. The external wall is required to continue to the underside of the non-combustible roof sheet or tile. Once again refer directly to the advice of lining manufacturers.

(FRL refers to the Fire Resistance level and is represented by the time in minutes as tested to AS 1530.4. Fire test criteria are expressed as structural adequacy/integrity/insulation. To obtain an FRL, a representative test sample of what is to be built and also installed, is subjected to the fire test and the load bearing, barrier to flame and gasses and insulation properties are measured.)
