Pink Batts Ceiling Insulation Segment formfrom NZ$99.22
Trusted for 50 years Pink Batts is a high quality glass wool insulation. Locally made for New Zealand conditions this is a great quality product.
We highly recommend installing the Pink Batts in biscuit form when you have no, or very little existing insulation. This is because installing blanket insulation over the top of the joists leaves a pocket of air between the insulation and the ceiling. This pocket can easily leak if the insulation is disturbed or there is a very small gap between blanket sheets. Installing biscuit form eliminates this as the insulation sits hard on the ceiling.
