Intertenancy Walls Explained: Fire, Acoustics & Performance

In this episode, we take a deep dive into intertenancy wall systems and how they perform in New Zealand construction.Focusing on the Masons Enviro IT Wall System, we explore how fire separation, acoustic performance and structural considerations come together to create safe, compliant and comfortable multi-unit buildings. From understanding AAC (autoclaved aerated concrete) and its properties, to how the full wall system is assembled on site, this episode breaks down the key components and principles behind its performance.We also discuss how these systems respond in fire scenarios, why acoustic design is more than just a compliance requirement, and what builders and designers need to consider during specification and installation to avoid common issues on site.Whether you’re working on townhouses, apartments or medium-density housing, this episode provides practical insight into getting intertenancy wall systems right - from design through to construction.About Masons:Masons began over 20 years ago, founded by Trent Mason, from a family of bricklayers, and has grown into a building-envelope focused company developing practical systems and products for building and construction in New Zealand and Australia.
