Sitting squarely between the popular R3.0 and R4.0 ratings, R3.5 Pink Batts are the precision pick for homeowners and builders who want to hit a specific NatHERS energy rating, meet an assessor's specification, or simply upgrade ceiling performance without going all the way to R4.0 or R5.0. It's the right amount of insulation for the right application.
Why R3.5 for Ceilings? R3.5 is a commonly NatHERS-specified ceiling insulation rating for Melbourne and Victorian homes where the energy assessor has calculated that R3.5 is the most cost-effective path to achieving the required star rating. Rather than defaulting to a round number, R3.5 allows builders and homeowners to hit compliance and comfort targets with precision to avoid the cost of over-specifying while still delivering genuine thermal performance.
It is generally considered insufficient as a stand alone ceiling insulation product for retrofit applications unless there is insufficient space for R5 to R7.
