R Value of Materials

The R-value is a measure of thermal resistance used for insulation materials. The higher the insulation R-value the better the thermal performance and the slower the heat loss or gains. Investing in a higher value can help to reduce energy wastage.

Resistance to Heat Flow

A typical Australian home has 70mm or 90mm wall studs. The highest rated residential product to fit a 90mm spacing is an R2.7 wall batt. Common R-values for walls include R1.5, R2.0 and R2.5 insulation.

Reduce Heat Loses

Local climate and budget are two factors which help determine what products are best for your home. Roof insulation R-value ranges from R2.5 to R7.0 and are between 120mm and 290mm thick.
