Product Description
The Masons Enviro AAC Intertenancy Wall System is based on Masons' Enviro AAC (autoclaved aerated concrete) panels – a dense yet lightweight material with proven acoustic and fire-resistant performance. It is fully NZBC compliant for both fire resistance (FRR) and sound transmission (STC).
Fully FRR & STC compliantThis system meets and/or exceeds the New Zealand Building Code’s minimum requirements for both fire resistance rating and sound transmission class. It scored a rating of -/120/120 for walls up to 10 m high. FRR -/120/120 for timber frame, and -/90/90 for light steel framing. Acoustic engineers Marshall Day reported a lab performance of 64 dB – higher than the minimum STC requirement of 55 dB for intertenancy walls.Structures or building elements with a fire-resistance rating are intended to separate people in the building from fire and allow time for a safe escape.
