We are aware of the negative environmental impact of construction but we see a solution in a better use of geo-sourced materials and energy. The question we intending to solve is: "how reach the highest balance point between performance and use of resources?" We are investing "our grey energy" the best way we can and once for all for developing a construction material with an infinite useful life. We are making possible several lives for new construction without additional impact. We foster durability, performant insulation, reversibility, reusability, and circular architecture. We've decided to solve all our "more issues" (more population, more degrees, more density in urban area, etc ...) with less material, less destruction, less energy consumption, and less waste ...
