Natural materials
Impressive performance

Symbol of a house with a label showing '-CO2' on a gray background.

Hempcrete binds more CO2 than is released during its production (-100 kg/m³ compared to +220 kg/m³ for normal concrete).
It transforms buildings into certified carbon sinks and supports global climate goals.

CO2 negativity

Symbol of an air filter with flame and protective shield icon representing fire resistance.

With an insulation value of 0.06-0.07 W/m-K, Hempcrete ensures excellent energy efficiency and reduces heating and cooling costs. At the same time, it offers fire resistance (EI120 at 12 cm plastered) and natural mold resistance, ensuring safety and durability.

Thermal insulation

Hemp grows regionally in just 110 days, requires little water, can be cultivated without pesticides and provides around 7 tons of building material per hectare - a renewable resource with a minimal ecological footprint.
