Hemp Insulation & Hempcrete Installation in California | GaiaCrete® by Mr Hemp House™
GaiaCrete® is the only insulation that's wildfire-resistant, seismically resilient, carbon-negative, and exceeds Title 24 — everything California demands.
Why California Homes Need GaiaCrete®
California's building challenges are unique. GaiaCrete® was engineered to meet every one of them.
Wildfire Defense
4+ hour fire rating without chemical retardants. Non-combustible lime-hemp matrix ideal for WUI zones. No toxic smoke when exposed to flame.
Seismic Resilience
GaiaCrete's flexible lime matrix absorbs seismic energy rather than cracking. Lighter than concrete, it reduces structural loads during earthquakes.
Title 24 Compliant
Exceeds California's strictest energy codes. Thermal mass cuts cooling by 30-50% across all 16 California climate zones.
Carbon Negative
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 Moisture
Coastal fog and marine air destroy fiberglass. GaiaCrete® breathes and regulates humidity naturally — mold is impossible at pH 12+.
Zero VOCs
California's strict Prop 65 and CARB standards are exceeded by GaiaCrete® — no added VOCs, zero formaldehyde, zero off-gassing. Ever.

Frequently Asked Questions
Is hemp insulation fire-resistant enough for California?
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.
Does hemp insulation meet California's Title 24 energy codes?
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.
