A bio-based insulation batt with a negative carbon footprint made from grass


Gramitherm® tackles the challenge of efficiency in buildings by providing an equally performant insulating material with an unrivaled environmental impact.

The primary component of the Gramitherm® insulation panel is grass, an element naturally abundant all over the world, with a short reconstitution cycle time. With an estimated lifetime of at least 50 years, Gramitherm® is easily and fully recyclable afterward. To source its panels' raw material, the solution's owner plans on primarily integrating local ecosystems, transforming grass from waste to useful product to build efficient buildings and homes.
