For Melbourne builders and homeowners looking to go beyond the minimum and build a home that's genuinely comfortable year-round, R4.0 wall insulation is a fantastic upgrade. Whether you're framing a new build or retrofitting an existing home, Pink Batts R4.0 fit neatly into standard wall cavities and deliver superior thermal and acoustic performance.

As with all pink-batts, they friction fit into place without the need for strapping into place, while preserving your coverage.

Why R4.0 for Walls? In Melbourne's Climate Zone 6, the NCC minimum for wall insulation is R2.0 — but minimum compliance rarely means maximum comfort. R4.0 wall batts are increasingly specified by energy assessors, architects, and NatHERS consultants as the go-to upgrade for homeowners and builders serious about energy efficiency, lower power bills, and achieving higher star ratings without a major cost blow-out.
