    Healthy Homes for North Dakota — Zone 7 Winters and Blizzard Wind

    Virtual Home Health Score assessments statewide. GaiaCrete™ specified in Zone 7 thicknesses for North Dakota design temperatures. Founding Mr Hemp House® dealer territories open by ZIP code.

    • Zone 7 design temperatures

      North Dakota winter design conditions expose every thermal bridge, and a cold interior surface in a humid room condenses immediately.

    • Blizzard wind infiltration

      Open-prairie blizzard wind pressurizes North Dakota houses, driving cold air and snow into any unsealed assembly.

    • Highest-tier radon

      North Dakota records some of the highest average indoor radon concentrations in the country, with basements the standard entry path.

    What Climate Zone 7 Means for North Dakota Homes

    North Dakota is the coldest state in the lower 48 by design temperature, sitting fully in Zone 7 with winter lows that make envelope continuity non-negotiable. Blizzard wind loads snow against walls and drives infiltration through the smallest gap. Radon levels here are among the highest recorded nationally, and the housing stock is small, dispersed, and hard to service.

    • North Dakota State Building Code (IRC and IECC based)

      North Dakota adopts the I-Codes as a state building code, with local jurisdictions handling enforcement.
