Intertenancy Walls Explained: Fire, Acoustics & Performance

In this episode of the Masons Podcast, we break down how intertenancy wall systems work in real-world construction across New Zealand.

If you’re a builder, architect, designer or developer working on townhouses, terraces or apartments, understanding fire separation, acoustic performance and system design is critical. We unpack the Masons Enviro IT Wall System - from what AAC (autoclaved aerated concrete) is, through to how these systems manage fire, reduce noise transfer, and meet New Zealand Building Code requirements.

You’ll learn:

• What intertenancy walls do and why they matter

• How fire separation works between units

• The role of acoustic performance in multi-unit living

• Key system components and how they come together

• Common installation mistakes and how to avoid them

• Design considerations for specifiers and builders

Whether you’re specifying systems or installing them on site, this episode gives you a clear, practical understanding of how to get performance right.
