Total Thermal R-Value
Expert Tip
Recommended attic insulation levels in cold climates typically require at least R-49 to R-60 (about 15-18 inches of fiberglass).
Calculation Methodology & Details
Formula
Multiplies insulation thickness by the thermal resistance coefficient of the selected material.
