Vapor-permeable Class A1 fire-rated hemp hurds and natural hydraulic lime insulation delivering mold-proof thermal comfort and carbon sequestration.
“Hemp-lime wall casting gives homes in Guanacaste that rare, solid, breathable comfort you only feel in centuries-old European stone structures, completely adapted to Costa Rican heat.”
Acts as dynamic humidity lung, eliminating condensation and tropical mold.
Hemp absorbs more CO₂ during growth than is emitted during processing.
High lime alkalinity creates a hostile environment for bugs and fungus.
Mineralized plant cellular structure will not ignite or emit toxic smoke.

Compare performance metrics against standard conventional construction materials in Costa Rica's tropical coastal climate.
| Engineering Metric | Hemp-Lime Bio-Insulation | Conventional Alternative A | Conventional Alternative B |
|---|---|---|---|
| Moisture Regulation | Dynamic hygroscopic buffering (Zero Mold) | Fiberglass traps moisture and sags | Spray foam traps rot in timber frame |
| Indoor Air Quality (VOCs) | Zero VOCs, hypoallergenic, lime purified | Off-gasses formaldehyde and particulates | Isocyanate chemical off-gassing |
| Fire Performance | Class A1 non-combustible mineral matrix | Melt points at moderate heat | Toxic cyanide smoke when ignited |
| Pest & Insect Resistance | High pH lime repels termites & rodents | Nesting ground for mice and bugs | Ants and termites tunnel through foam |
| Lifespan | 100+ Years (petrifies stronger with age) | 15-20 Years before degradation | 20-25 Years |
