PHOTO REQUIRED or additional documentation required of foundation wall insulation per ANSI/RESNET/ICC 301-2019 APPENDIX B and MINHERS Chapter 9. If applicable/visible, Rater/RFI verifies and documents the correct foundation wall types, thicknesses & studs, lengths & heights, heights above & depths below grade, locations, and if visible, insulation R-values, grades & dimensions.
- Be sure that where multiple foundation wall types exist, they are handled separately, including where their “location” with respect to conditioned areas of the home may vary between wall types and within the same wall type.
SCORING: "Satisfactory" when correct or "Unsatisfactory" when incorrect.
GUIDANCE:
R-Value and Grading - Rater/RFI is within ANSI/RESNET/ICC 301-2019 Appendix A depth/void variance for insulation type and grade identified
Height/Depth Values - QAD value within 1' of Rater/RFI value
Exterior Perimeter - QAD value within 5% of Rater/RFI value
