R6.0 Insulation
The easiest way to increase the R-value of a product is to increase the roof insulation thickness, hence R6.0 ceiling insulation batts are between 250mm and 275mm thick. These glasswool products can be easily cut using a sharp retractable knife. R6.0 insulation is an effective barrier against the summer heat and winter cold.
Maximize Your R6.0 Insulation Potential
ICANZ claims that you can save up to $299 per year on your electricity bill with ceiling insulation (depending on your climate zone). The higher the R-value, the better the thermal performance of the insulation. R6.0 insulation is the highest available rating for Earthwool and Pink Batts.
If your ceiling was insulated decades ago, there is a good chance that it has lost some of its effectiveness. Even if the insulation was considered a good quality product at the time, it might be delivering less thermal benefit than it was originally specified to deliver, and it may be time to consider an upgrade. Where you live in Australia will effect the type and level of insulation required. Passive design techniques should be used in addition to R6.0 insulation. If the house is completely exposed to the sun, the built-up heat can be kept in by the insulation, resulting in an ‘oven’ effect.
