Does cellulose prevent the common problem in Australia of insulation products not reaching their advertised performance after they e installed?
A. Yes. When Australian manufactured batt-type insulation products are installed in thicknesses greater than the ceiling joists, the uninsulated areas left above the ceiling joists substantially reduce the batts’ advertised insulation performance. For example, in hardwood timber ceiling joists at high insulation levels of R 4.0 and above, batt insulation performance can be reduced by up to 45% to R2.2 by the heat rising up through the timber joists.
