The 162mm AFS Logicwall intertenancy wall system provided a 55 STC acoustic rating, 240 minute fire rating, and helped to speed up construction with no need to strap or line the walls. 

Terra Lana Chatterblock Acoustic Wool Insulation helps architects achieve acoustic comfort, thermal performance, moisture management and long-term durability within intertenancy wall and midfloor assemblies.

A terrace housing development in Ponsonby demonstrates how a fibre cement structural flooring system can deliver a robust and stable mid-floor substrate in multi-level residential construction.

CLT intertenancy walls offer a high-performance, sustainable alternative to concrete and steel, meeting fire, acoustic, and structural requirements for apartments, hotels, and offices. Red Stag TimberLab's precision-fabricated CLT systems, from single panels to double-wall configurations, deliver up to 120-minute FRR, Rw 55–65 acoustic ratings, and up to 50% faster construction.

Superior sound isolation with a smaller footprint.

Woodspan PLT panels delivers high-performance acoustic insulation and fire safety compliance for modern medium-density builds.

Now CodeMark-certified, Masons’ Enviro AAC Intertenancy Wall System gives builders a faster, lighter way to meet New Zealand’s strict requirements for fire and acoustic performance.

Achieve faster, easier, and more predictable intertenancy design across apartments, terraced housing, hotels, retirement villages, and mixed‑use developments.

The INTEGRA system exceeds fire and acoustic requirements for multi-unit developments, delivering a minimum two hour fire rating (FRR 120/120/120) and a minimum STC rating of 64, with the possibility to achieve a rating of up to 67.

Backed by Marshall Day testing, Dimond's Flatdeck, Hibond 55 and Hibond 80 systems exceed acoustic performance requirements for intertenancy floors, reaching up to 57dB STC bare for a 200mm Flatdeck.

GIB provides three basic types of intertenancy wall systems — single frame walls, staggered studs or double frames, and double frames with central barrier. Here's what to consider to specify the right system for your project.
