GaiaCrete® handles Illinois' extremes — -20°F wind chills to 95°F humid summers, superior thermal mass, and permanent mold prevention.
Illinois' 115°F temperature swing demands insulation that handles both extremes.
Thermal mass handles -20°F wind chills. 30-50% lower heating bills even in the worst Chicago winters.
Hygroscopic walls naturally buffer Illinois' 80%+ summer humidity without trapping moisture.
pH 12+ makes mold impossible. Critical for Illinois basements and older homes.
Monolithic walls withstand Chicago's legendary wind loads better than frame construction.
From -20°F to 95°F — GaiaCrete® handles the full range. Fiberglass and spray foam can't.
Every wall sequesters CO₂. Meets Illinois' growing sustainability requirements and net-zero goals.
