ROOTMAN
Thermal and acoustic insulation made from living roots: natural, incombustible and breathable panels and blocks. Patented technology with over 10 years of R&D; material selected for the UN's ECLAC building.
Rootman is a thermal and acoustic insulation material developed in Chile from a root mat: oat and barley roots grown on trays that, around ten days after sowing, form a natural, 100% biodegradable panel through patented technology. The material, free from petrochemical additives, declares a thermal conductivity of 0.034-0.036 W/mK, comparable to conventional insulation materials, an acoustic insulation of Rw 48 dB in its panel format, and outstanding fire behaviour: its fire-resistant insulation (F-90 technology, Thermoroot) takes around one hour to start burning under direct flame exposure. It is offered as the core for SIP-type panels and as insulation for walls and roofs, aimed at industrialised timber construction. Its nature-based innovation profile has earned it the backing of ECLAC (United Nations), which has trusted the material for its facilities, and growing attention from the sustainable construction press as a renewable, ultra-short-cycle alternative to synthetic insulation materials.
For its radical innovation: they don't manufacture the insulation, they grow it. Using living roots to create incombustible thermal and acoustic panels is biology applied to architecture at its finest.

Aislante natural chileno de raíces de avena/cebada (patentado). Sin EPD ni ACV público. Verificado en ficha del fabricante: λ 0,035–0,037 W/m·K (NCh 853), densidad 45–60 kg/m³, resistencia al fuego F-90 (declarada), espesores 50/75 mm, biodegradable y sin aditivos. ✅ Corregido: el GWP −39,5/m² era casi con seguridad una mala lectura del dato sectorial '39% de las emisiones de CO₂' (no es del producto), y el 'CO₂ secuestrado 150' no tenía fuente → retirados.
