Soundblox Carbstone absorbs both sound and CO₂ and is also 100% circular and cement-free. With these innovative acoustic blocks, you can cleverly combine all essential properties—such as circularity, stability, fire resistance, and durability—into a single wall for all indoor and outdoor applications. Thanks to the latest innovation, Soundblox is now available as a ready-to-install prefabricated wall. This reduces nitrogen emissions at the construction site by up to 70% and construction costs by up to 40%.

Soundblox Carbstone is now available as a ready-to-install prefabricated wall for both indoor and outdoor applications. This smart building system can also be seamlessly combined with standard Carbstone facing blocks within the same wall, delivered and installed as a complete unit. Of course, walls made exclusively of standard Carbstone blocks are also available.
These innovative elements offer unmatched acoustics (both sound absorption and sound insulation), maximum fire resistance, and ultimate stability. Not only are you building sustainably, but you also benefit immediately from lightning-fast and exceptionally clean installation. The result is spectacular cost savings of up to 40% and a nitrogen reduction of up to 70%.


Just like the Soundblox building blocks, this super-smart wall is 100% circular, cement-free, and CO₂-negative (EPD-verified), enabling a massive reduction in CO₂ emissions. That’s because CO₂ is stored within the blocks and is no longer released. Depending on the size of the wall and the chosen block dimensions, the CO₂ reduction for each project can be calculated precisely. Want to know how much CO₂ you can save on your project? Let us know!
After installation, the wall continues to absorb CO₂ from the air, causing it to harden further and further and increasing its compressive strength. Ideal for industrial applications. This technology represents a revolutionary step toward future-proof, CO₂-neutral, and emission-free construction.
