See all benefits

Negative carbon

The high CO2 sequestration determines that the material's carbon footprint is negative.


Very low built-in energy

93% of energy consumption in the manufacture of the product is biomass that results from the process itself.



Thermal resistance of the roofing solution equal to 1.96 m2ºC / W, not considering the surface and slab resistances. Calculation value for saturated materials;

The simulations in a bioclimatic chamber reveal that, after a period of precipitation, the system recovers quickly to a behavior similar to that registered under normal conditions (without precipitation);

Maximum vertical drainage capacity above 20 liters / (min.m2) or 20 mm / min;
Retention capacity above 17 liters / m2;

Isolation to aerial sounds, determined in vertical acoustic chambers (EN ISO 10140), RW = 59 (-2; -8; -1; -8) dB. Result obtained with a reference slab.
