Rumett casts paper-free mineral wall panels from gypsum and bio-ash. The surface is finished at the point of casting — no paint, no filler, no finishing step. The panels are solid mineral with no paper facing, cast 13 mm thick in a 600 × 1200 mm reference format, and screw-fixed to a supporting steel or timber framework rather than glued. Because the fixings stay accessible, a panel can be removed and reinstalled in a new layout instead of being broken out. The panels are classified A1 for reaction to fire in accordance with EN 13501-1:2018, issued by DBI. The classification applies to the product defined in the report; coverage of sealed or lacquered variants remains to be confirmed. The report is available on request. Rumett is based in Copenhagen and won the Danish Design Award 2025 in Young Ideas. We work with architects and interior fit-out teams on sample requests and project documentation.
