GaiaCrete® is the only insulation that's wildfire-resistant, seismically resilient, carbon-negative, and exceeds Title 24 — everything California demands.
California's building challenges are unique. GaiaCrete® was engineered to meet every one of them.
4+ hour fire rating without chemical retardants. Non-combustible lime-hemp matrix ideal for WUI zones. No toxic smoke when exposed to flame.
GaiaCrete's flexible lime matrix absorbs seismic energy rather than cracking. Lighter than concrete, it reduces structural loads during earthquakes.
Exceeds California's strictest energy codes. Thermal mass cuts cooling by 30-50% across all 16 California climate zones.
California leads on climate policy. GaiaCrete® is carbon-negative — it absorbs more CO2 than it produces, aligning with CA's 2045 carbon neutrality goals.
Coastal fog and marine air destroy fiberglass. GaiaCrete® breathes and regulates humidity naturally — mold is impossible at pH 12+.
California's strict Prop 65 and CARB standards are exceeded by GaiaCrete® — zero VOCs, zero formaldehyde, zero off-gassing. Ever.

GaiaCrete® installation available across the Golden State.
GaiaCrete® achieves a 4+ hour fire rating without chemical flame retardants — exceeding California's stringent fire code requirements. The lime-mineral matrix is inherently non-combustible, making it ideal for WUI (Wildland-Urban Interface) zones where wildfire risk is highest.
Yes. GaiaCrete® hemp insulation meets and exceeds California Title 24 energy efficiency requirements. Its thermal mass performance reduces cooling loads by 30-50%, and its moisture-regulating properties eliminate the condensation issues that plague conventional insulation in California's diverse climate zones.
