R2.5 Ceiling Insulation

R2.5 Ceiling Insulation – Brand & R-values

In an uninsulated home between 25% and 35% of winter heat losses and summer heat gains occurs through the ceiling. You can increase the energy efficiency of your home and reduce your energy bills by installing R2.5 ceiling insulation.

If two products have the same R-value, then their insulating performance will be the same. No certified insulation brand is better than the other – it all comes down to the R-value. Each of the brands we sell meet the Australian Standard AS/NZS 4859. Australia is divided into a number of climate zones which help determine which insulation is best for each region. In the hot climates up north, properly installed reflective foil insulation is as important as bulk insulation products such as glass wool or polyester.
