Insulation right across Queensland.

What QLD’s climate actually needs

SE QLD is climate zone 2, so we don’t oversell the R-value.

Brisbane and the South East Queensland coast sit in NCC climate zone 2, the warm-humid zone. The minimum added ceiling insulation the National Construction Code asks for here is about R2.5, modest, because the climate is mild compared with the cold southern states. We install around R3.0 cellulose as standard, roughly 20% over that minimum, which is plenty for this climate. There’s no point paying for a much bigger number Queensland’s weather doesn’t reward.

Up on the range and across the South Burnett tablelands (Toowoomba, Kingaroy, Nanango and the Granite Belt) you’re in the cooler Climate Zone 5, with genuine winter frosts, so the R-value to aim for is higher and underfloor insulation earns its keep. Far North Queensland is the tropical Zone 1. The right R-value changes with where your house sits, and we’ll tell you which applies to yours.
