Install R2.5, R2.7, R3.0 & R4.0 Batts – The Right R-Value for Every Aussie Home

Not all homes are the same, which is why choosing the correct insulation R-value is crucial. At Home Energy Rating, we supply and install batts specifically tailored to your region and home design.

  • R2.5 Batts – Ideal for milder climates like Brisbane or coastal NSW. Offers solid thermal resistance while keeping costs affordable.
  • R2.7 Batts – A step up in performance, suitable for mixed climates and homes wanting greater comfort and efficiency.
  • R3.0 Batts – Best for cooler zones such as Melbourne, Canberra, and Hobart, where winter chills demand strong floor insulation.
  • R4.0 Batts – Premium-grade insulation for maximum energy savings and comfort, recommended for southern regions and eco-conscious builds aiming for sustainability.

Our professional team ensures every batt is cut and fitted perfectly between joists, leaving no gaps or thermal bridges. This guarantees consistent performance, reduced draughts, and long-term comfort for your household.
