Non-Toxic Building Materials — Healthier Alternatives for Every Part of Your Home
Every material in your home either contributes to your health or takes from it. We focus on bio-based and mineral-based building materials selected for lower emissions and durability.
Insulation: GaiaCrete™ & Hemp-Based Solutions
GaiaCrete™ Hempcrete
Our proprietary hemp-lime composite — biogenic carbon storage, Class A flame spread results (ASTM E84), and vapor-permeable for moisture buffering. For walls, floors, and roofs.
Explore GaiaCrete™ HempcreteNatural Lime Plasters
Breathable, alkaline wall finishes that absorb CO₂ as they cure. Beautiful, durable, and no-added-VOC.
Hemp Fiber Insulation
Flexible batt insulation made from hemp fibers. A bio-based alternative to conventional fiberglass insulation, with different handling, emission, and moisture characteristics depending on the product and assembly.
Bio-Based Sealants & Finishes
Plant-based wood oils, waxes, and sealants formulated as lower-emitting alternatives to conventional solvent-based finishes.
Why Your Current Building Materials May Be Toxic
| Feature | Natural (Hemp/Lime) | Conventional |
|---|---|---|
| VOC Emissions | No added VOCs; no off-gassing detected in third-party testing | Commonly higher (formaldehyde binders, blowing agents) |
| Flame Spread (ASTM E84) | Class A flame spread result (surface burning, not an hourly rating) | Often requires chemical retardants |
| Mold Resistance | Mold-resistant in lab testing due to high-alkalinity mineral composition | Susceptible when wetted |
| Carbon Impact | Stores biogenic carbon; lime reabsorbs CO₂ over time | Carbon-intensive |
| Service Life | 100+ year service-life potential documented in hemp-lime research | Service life varies significantly by product, assembly, exposure, installation quality, and maintenance. |
| Indoor Air Quality | Vapor-permeable; buffers humidity within the assembly | Can off-gas over service life |
