Minnesota's extreme cold makes insulation the single most important building decision. GaiaCrete® hemp insulation maintains R-value at -30°F and below — unlike fiberglass which loses effectiveness. Its thermal mass keeps homes warm through Minnesota's long winters.
Extreme cold (-30°F+) with humid summers. Minnesota's arctic winters demand maximum insulation. GaiaCrete®'s thermal mass excels in extreme cold while managing the moisture transitions between seasons.
GaiaCrete® stores heat and releases it slowly — maintaining comfort through extended cold periods. Unlike fiberglass, it performs better as temperatures drop.
Breathable hemp-lime construction prevents moisture buildup that causes ice dams, rot, and mold in conventional insulation.
Zero flame spread rating — GaiaCrete® chars rather than burns, producing no toxic smoke. Critical protection for your family.
Monolithic walls eliminate air gaps and resist wind penetration — essential for exposed, windy climates.
The alkaline lime binder creates a pH 12+ environment where mold, mildew, and bacteria cannot survive.
No off-gassing, no formaldehyde, no toxic chemicals. Breathe clean, healthy air all winter with windows sealed tight.
