    Healthy Homes for Alaska — Permafrost, Vapor Drive, and Freight

    Virtual Home Health Score assessments statewide, including off-road communities. GaiaCrete™ evaluated against Alaska's Zone 7-8 design temperatures. Founding Mr Hemp House® dealer territories open by ZIP code.

    • Permafrost and foundation heat loss

      Heat escaping an Alaskan foundation thaws permafrost and settles the structure, so ground-contact detailing matters as much as wall R-value.

    • Extreme vapor drive

      With 100-degree indoor-outdoor temperature differences, Alaskan walls face vapor pressure that will find any interruption in the air control layer.

    • Freight distance and material logistics

      Barge and air freight to Alaskan communities means material choices are constrained by shipping weight, packaging, and season.

    What Climate Zone 7-8 Means for Alaska Homes

    Alaska is the only state with Zone 8 territory, and much of the Interior sits on discontinuous permafrost that punishes any heat leaking into the ground. Winter means months of sealed houses, wood and oil heat, and vapor drive strong enough to push moisture straight into wall assemblies. Freight distance makes every material decision a logistics decision.

    • Alaska adoption of the IBC/IRC through the State Fire Marshal

      Residential energy requirements are largely driven by AHFC's Building Energy Efficiency Standard for financed construction; local enforcement varies widely.

    Start With Your Home Health Score in Alaska

    Virtual Healthy Home Assessments available in Alaska. In-person coverage expanding.

    Home Health Score

    A free screening that scores your home across indoor air quality, moisture and mold risk, building materials, and ventilation — so you know where to look first.

    Healthy Home Assessment

    A professional walkthrough of materials, moisture conditions, and ventilation, delivered as a prioritized action plan. Screening and guidance — not a medical or diagnostic service.

    One part of the platform

    GaiaCrete™ Insulation & Building Solutions in Alaska

    GaiaCrete™, a hempcrete alternative, is Mr Hemp House®'s bio-based hemp-lime building material — used for new construction, retrofits, and insulation upgrades. It is one offering inside the platform, alongside the Home Health Score and Healthy Home Assessment.

    • Thermal performance R-2.5+ per inch
    • Class A surface burning characteristics (ASTM E84)
    • Mold-resistant at pH 12+
    • 100% Biobased Carbon Content (ASTM D6866-22)
    • Vapor-permeable, no added VOCs
    • Net carbon sink by design

    Actual thermal performance varies by formulation, density, moisture content, installation method, and complete wall assembly. Final whole-wall thermal performance depends on the complete assembly, including material density, framing, finishes, thermal bridging, moisture conditions, and installation.
