Built to the Minnesota Energy Code
Every new home in Minnesota is inspected against the Minnesota Residential Energy Code. For most of our service area (Climate Zone 6), the key insulation and air-leakage requirements are:
- R-49 in the ceilings
- R-20 in wood-framed walls, or R-13 in the cavity plus R-5 continuous insulation
- A blower door test result of 3 ACH50 or less
- Depth markers in blown attics, at least one per 300 square feet
- A posted insulation certificate listing the R-values installed
