For the environment, it means that fewer boards need to be transported to a construction site, which already reduces carbon emissions related to transportation. Since we are aiming for the boards to be lighter in weight, this again results in a smaller carbon footprint in the transportation phase. We are in pursuit of plasterboards with a 40% reduced carbon footprint.

For the contractor working on construction sites, it means a product that is more efficient to use during the building process. They’re only moving half the materials for the same job. The product is easier to handle due to the reduced weight and could potentially be massively cost-effective, requiring only a single layer instead of two. This benefit applies across the board — from small to large-scale projects — and the larger the construction, the greater the savings in the end.

As people in the construction industry are aware, recyclability is a major concern at the moment. In Europe, scheduled regulations will soon go into effect, heavily geared toward making the industry more sustainable, with a strong emphasis on recyclability.

Rumett was created to challenge the wasteful habit in architecture of treating interior walls as disposable. Traditional plasterboards are demolished with every renovation, even when they still function. Rumett reimagines the wall as flexible, maintainable, and responsive — designed for disassembly with screws, not glue. Our panels can be easily replaced, reducing waste, dust, and mess.

We integrate fly ash from Danish biomass power plants into our panels, transforming waste into a durable building product. Our Life Cycle Assessment shows a 40% reduction in CO₂ emissions compared to traditional plasterboards.

Rumett believes sustainability shouldn’t compromise expression. Our surface design offers a tactile, mineral texture that can stand alone or be painted. Our paper-free design improves air quality, making it suitable for both residential and public spaces.

Rumett doesn’t just offer a new type of wall — it offers a new mindset. It enables flexible, movable architecture with minimal tools: just screws. Clients feel empowered to change their space without destruction. We’ve seen it in offices and exhibitions where walls are easily rearranged or reused.

We’ve built Rumett through hands-on iteration and real-world testing. Our panels reduce labor time by 30–40%, with no taping, sanding, or drying required. They have passed initial fire tests, with full-scale certification planned for future production.
