Insulation Types

Glass wool batts (ceiling): Most common, cost-effective. R-value R3.2–R6.0. Polyester batts: Good allergen option. Similar cost to glass wool. Blown-in loose fill (ceiling): Good for hard-to-reach areas, fills gaps well. Foil (underfloor): Reflects radiant heat, moisture-resistant. NZ Building Code no longer accepts foil for new builds but it performs well for retrofits. Polyester batts (underfloor): Better cold performance than foil. More expensive.
