    Hemp Insulation & Hempcrete Installation in New Hampshire | GaiaCrete® by Mr Hemp House™

    New Hampshire's cold winters, historic homes, and high energy costs make GaiaCrete® the perfect solution. Superior thermal mass, ice dam prevention, and breathable construction for New England's most demanding climate.

    Why New Hampshire Homes Choose GaiaCrete®

    Cold New England winters with coastal and mountain exposure. New Hampshire's demanding climate needs insulation that retains heat, prevents ice dams, and breathes in historic homes.

    Superior Thermal Mass

    GaiaCrete® stores heat and releases it slowly — maintaining comfort through extended cold periods. Unlike fiberglass, it performs better as temperatures drop.

    Moisture Management

    Breathable hemp-lime construction prevents moisture buildup that causes ice dams, rot, and mold in conventional insulation.

    Fire Resistant

    Zero flame spread rating — GaiaCrete® chars rather than burns, producing no toxic smoke. Critical protection for your family.

    Wind Resistant

    Monolithic walls eliminate air gaps and resist wind penetration — essential for exposed, windy climates.

    Mold-Proof (pH 12+)

    The alkaline lime binder creates a pH 12+ environment where mold, mildew, and bacteria cannot survive.

    Zero VOCs

    No off-gassing, no formaldehyde, no toxic chemicals. Breathe clean, healthy air all winter with windows sealed tight.
