Inquiry
ID request for implementing designs that limit compaction of insulation, particularly at the edge of the roof rafter.
Ruling
This is good practice, but not worthy of ID credit. Any insulation that is compressed should be discounted by the energy rater when assessing the R-value, as per the HERS guidelines. The proposed strategy will enable insulation R-values not to be discounted.
