New Radiant Barrier Study by US Dept of Energy and
Oak Ridge National Labs
Andre Desjarlais of Oak Ridge National Labs
presented the new radiant barrier study by ORNL and the US Department of Energy.
After running exhaustive testing at the Large Scale Climate Simulator, it was
concluded that attaching sheet radiant barrier to the underside of the roof
rafters is significantly more efficient that either applying Radiant Barrier
Decking or Interior Radiant Control Coatings (radiant barrier paints). With
radiant barrier finding its way into building codes and energy credits, it's
important to know the most efficient method of attic installation is still
stapling radiant barrier under the roof rafters.
