Bloque de cáñamo Cannabric
Spanish pioneer in hemp and lime blocks (hempcrete) for natural building.
Cannabric is a solid, load-bearing block manufactured in Guadix (Granada) from hemp, aggregates and natural mineral binders. A pioneer of hemp construction in Spain, it combines structural capacity, insulation and a high thermal inertia that helps regulate indoor temperature in summer and winter. It is breathable, healthy and low-footprint, incorporating a renewable crop that fixes CO₂ as it grows; it is complemented by panels and construction systems from the same family.
Pioneer in hempcrete in Spain with over 20 years' experience. Potential for carbon negativity.

No
GWP-total = −0,624 kg CO₂eq/kg (negativo: es un balance NETO, el bloque retiene más CO₂ del que emite en su ciclo de fabricación), según ficha técnica del fabricante (Cannabric, bloque macizo conforme a UNE 41410, fabricado en Guadix). ⚠️ Dato de fabricante, NO una EPD tipo III verificada por tercero (ISO 14025 / EN 15804). Al ser un GWP neto y no una medida de secuestro bruto, NO se traslada al campo CO2_Secuestrado_kg_m3 (se deja vacío para no mezclar conceptos con Steico/Lunawood, cuyos m³ sí son carbono biogénico almacenado de EPD). Bloque macizo: densidad aparente ≈1.300 kg/m³ (1,3 kg/dm³; densidad absoluta seca 1.100 kg/m³, UNE-EN 772-13), λ del bloque 0,19 W/m·K, resistencia al fuego >RF 120, Rc característica 1,3 N/mm².
