R5.0 Pink Ceiling Batts are 220 mm FBS-1 bio-soluble glasswool from Fletcher, Australian made using up to 80% recycled content. This is a high performance ceiling spec, normally driven by a cold climate zone or an energy rating target rather than by the minimum code requirement.
Depth is the constraint
220 mm of batt needs 220 mm of clear space to sit at its rated thickness. Roof spaces are usually generous at the ridge and tight at the eaves, and a batt crushed at the perimeter performs like a thinner one exactly where the ceiling is most exposed. Measure the tight spots before ordering.
Fire and bushfire
Non-combustible to AS/NZS 1530.1, rated BAL Low through to Flame Zone under AS 3959, and it meets NCC 2022 clause C2D10(1) for non-combustibility.
Sizes
Eight batts per pack at 1160 mm long. The 430 mm width covers 3.99 m² and the 580 mm covers 5.38 m². Coverage per pack keeps falling as the R-value climbs, so allow for more packs than an R3.5 job over the same ceiling.
On site
Cuts with a knife and friction fits between the joists. Let the batts recover to full loft, do not compress them, keep them dry, and keep the clearances downlights and flues require.

Fitting notes
Cuts with a knife and friction fits between joists, so it holds without fixings. Keep batts at full loft and let them recover before installing. Do not compress them into the space, because a squashed batt delivers less than its rated R-value. Keep the product dry at all times, before, during and after installation.
