Massachusetts has the oldest housing stock in America and some of the highest energy costs. GaiaCrete® hemp insulation is the ideal retrofit — breathable for old walls, superior thermal performance, and mold-proof for New England's wet climate.
Cold winters with humid summers and coastal exposure. Massachusetts's historic housing stock and nor'easter storms demand insulation that breathes, insulates, and endures. GaiaCrete® delivers on all three. Central-Mass homeowners can start with our Worcester hemp insulation guide.
GaiaCrete®'s thermal mass moderates temperature swings — keeping homes cool in summer and warm in winter without excessive energy use.
Breathable hemp-lime matrix manages humidity naturally — preventing the mold and moisture damage common in variable climates.
The alkaline lime binder creates an environment where mold, mildew, and bacteria cannot survive.
Monolithic construction provides superior wind and storm resistance compared to frame-and-batt building.
Zero flame spread rating — GaiaCrete® chars rather than burns, producing no toxic smoke.
No off-gassing, no formaldehyde, no toxic chemicals. Healthy indoor air from day one.
