BRANZ Appraised
BRANZ Appraised – Appraisal number 985 (2018).
All-in-one
Provides structural support as well as fire and sound insulation.
Faster
Installation time is significantly reduced compared to traditional IT wall solutions.

Space Benefits
- At 130mm thickness, it’s one of the thinnest options on the market, saving 260mm per IT wall compared to traditional options.
- For example, for ten 5.5m-wide units, you save 2.6m. That’s enough space for a single lane road, additional car parking or green space compared to some traditional methods.
- In a space where you’d fit 20 traditional terraced units, you can now fit 21. You get more housing in the same area, without compromising on interior living space.
