Reliable Materials: The Masons Enviro AAC Intertenancy Wall System is a secondary element based on the Masons Enviro (TM) AAC panel – a 50 mm thick panel. It is manufactured from cement, sand, lime, and water, aerated with an expanding agent. Soft blocks are moulded from the mixture, then sliced into the required panel size, and cured in a steam-pressure autoclave for up to 12 hours.

Exceeds Minumum Requirements: This system meets and/or exceeds the New Zealand Building Code’s minimum requirements for fire resistance rating and sound transmission class. It scored -/120/120 for walls up to 10 m high. FRR -/120/120 for timber frame and -/90/90 for light steel framing. Acoustic engineer 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.

Easy to Use, Flexible and Fast: The Masons system is construction-friendly and designed for simplicity and flexibility. As few as two builders can install the system, and installation can flow around other work on-site. No weather protection is needed for the AAC panels when work stops, making on-site storage simple. The horizontal stack construction minimises cutting and waste.

Masons Intertenancy Wall has an FRR of -/120/120, making it suitable for various building uses, including where more time is needed for safer fire evacuation.

A higher FRR will more effectively retard fire, allowing firefighters more time to attend and effect less damage to adjacent tenancies.

Designed for Buildability: The system can be installed up to three stories continuously, without interruption, and there is often no need for extra accessories or fiddly work at mid-floors junctions. Services can be run down the framing on either side of the AAC panels, and materials are carried in smaller parts when site access is difficult. The ACC system is easier for everyone on the job.
