FAQ

What R-value do I need for walls and ceilings in Perth?

Perth falls under NCC Climate Zone 5, which sets minimum total R-values for walls and ceilings under Section J. The exact requirement depends on your building class and wall/ceiling construction. For higher R-values in thinner profiles, also consider our PIR Boards. 📌 NOTE — confirm current minimum R-values with your certifier before publishing.

What's the difference between thermal and acoustic insulation?

Thermal insulation resists heat transfer — keeping buildings cooler in summer and warmer in winter. Acoustic insulation reduces sound transmission between rooms or from outside. Some products in the Fletcher and CSR Martini ranges deliver both functions in a single batt, making them well suited to party walls and ceiling applications where both are specified.

Should insulation be installed with a reflective foil?

In most WA wall and ceiling systems, a reflective foil or sarking layer on the warm side adds measurable thermal resistance and assists with condensation control. Pairing insulation with a product from our foils and membranes range is standard practice for compliant wall assemblies in Perth conditions.

Can I get insulation delivered to my Perth building site?

Yes — Aussie Plasterboard delivers across Western Australia from our Osborne Park warehouse. For project quantities, submit a quote request and our team will confirm availability and lead times.
