PD_Q12_AGW Version 7.1.1

PHOTO REQUIRED of above grade wall insulation per ANSI/RESNET/ICC 301-2019 APPENDIX B and MINHERS Chapter 9. Raters/RFIs are responsible for documenting reasons for missing photos. Rater/RFI verifies and documents the correct above grade wall types, insulation types, R-values, insulation thicknesses, insulation grades, stud spacings/dimensions, framing factors, areas, locations and exterior surface colors.

• Be sure that where multiple above grade 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.
• In homes with Advanced Framing, verify that adequate insulation exists in 3-stud corners, interior/exterior wall intersections, behind blocking, behind any exterior wall tubs/showers/fireplaces, etc. This verification is for insulation grading. Areas have been inspected and verified; any area of missing or inadequate insulation has been documented.

SCORING:

• Satisfactory: No errors in verification
• 1: One to two minor errors in verification (listed below) (this is per wall)
• 2: No photo OR three to four minor errors (listed below) in verification OR one to two major errors in verification (this is per wall)
• 3: Five or more minor errors (listed below) OR three or more major errors in verification (listed below) (this is per wall)

GUIDANCE:

Minor AGW Verification Errors:

• Incorrect Wall Construction verified
• Insulation R-Value of each verified AGW off by 5% to 10%
• Insulation thickness of each verified AGW off by 0.5 to <1.0 inch
• Incorrect Gypsum thickness verified
• AGW Surface Area of each verified AGW off by 4% to 7%
• Incorrect Surface Color verified
• Incorrect Insulation Location verified

Major AGW Verification Errors:

• Insulation R-Value of each verified AGW off by greater than 10%
• Insulation thickness of each verified AGW off by greater than 1.0 inch
• Incorrect Insulation Grade value verified (based on ANSI/RESNET/ICC 301-2019 Appendix A - depth/void variance for insulation type and grade)
• Incorrect stud depth, spacing, or framing fraction verified
• AGW Surface Area of each verified AGW off by greater than 7%
