Bradford Gold wall insulation batts are specifically designed to deliver optimal performance in exterior cavity walls. You can lose up to 25% of the heat in your home through the walls in winter and around the same amount of heat can enter in through the walls during summer. Climate is a major factor to determine the R-Value best suited to your home. R-Value, also referred to as R-Rating, represents the thermal resistance of the insulation – a higher R-Value mean a higher performance insulation. Bradford Gold Hi-Performance wall batts are available in R-Values of R2.0 to R4.0, offering an exceptional level of thermal protection even in the most extreme Australian climates. Unlike other forms of heating and cooling control, wall insulation requires no maintenance or replacement.
