Changes incorporated in to ‘AS3959; Construction of Building in Bushfire-Prone Areas’ has provided a pathway for a deemed to satisfy and alternative solution to glazing based on a BushFire Attack Level (BAL) rating.

The deemed to satisfy approach prescribes glazing and bushfire resistant shutters and/or specific metal screens to the glazing area as the BAL moves through BAL 12.5 through to BAL 40 (refer to AS3959 for specific details). For consumers the presence of either or both of these elements may provide an unsightly and undesirable additional feature to the buildings external appearance.
