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.
