It is the entry point of the Gold ceiling range, and the one to reach for when the ceiling depth is tight or when R2.5 is genuinely all the job calls for.\u003c\/p\u003e\n\u003ch3\u003eWhich width\u003c\/h3\u003e\n\u003cp\u003eTwo options, both 1160 mm long and 16 batts to a pack: 430 mm wide covering 7.98 m², and 580 mm wide covering 10.77 m². Australian ceiling framing is normally set out at 450 mm or 600 mm centres, and the two batt widths follow that convention. Measure your actual joist spacing before ordering rather than assuming, because a batt that is too narrow leaves a gap at every joist.\u003c\/p\u003e\n\u003ch3\u003eIs R2.5 enough\u003c\/h3\u003e\n\u003cp\u003eThat depends on where the house is and what the rest of the build-up does. There is no single national ceiling R-value. \u003ca href=\"\/blogs\/blog\/r-value-australian-climate-zones\"\u003eR-value by Australian climate zone\u003c\/a\u003e covers how the target gets set and what else changes it.

Do not compress the batt to make it fit a shallower space, because a bulk insulation batt only delivers its rated R-value at full thickness. Keep the clearances any downlights or flues in the ceiling require.\u003c\/p\u003e\n\u003cp\u003eThermal rating is declared to AS\/NZS 4859.1 by the manufacturer.
