R3.5 Batts Glasswool Insulation with AS/N2S 4859.1 Certificate OverviewGlasswool Batts is specifically designed to deliver optimal performance in exterior cavity walls.R-values are the measuring tool we use to rate the level of thermal resistance.Essentially, the higher the R-Value the more effective the insulation is.Glasswool wall batts are available in R-Values from R1.5 – R2.0.Manufactured from glasswool, the batts are specially stiffened and treated to provide a moisture resistant insulation –meeting the Building Code of Australia's minimum requirements for energy efficiency in homes.The glasswool we use is made up of very thin glass fibres that are spun like fairy floss to create millions of air pockets.These air pockets are very poor conductors of heat and resist the flow of air or radiation through the insulation.
