A little less added.
A lot more character.

The surface is
already the finish.

Gypsum. Bio-ash. Nothing to hide.
Rumett brings the raw beauty of mineral materials into walls and ceilings. No paint. No filler. Just a surface made to be seen.

01 / The collections

Nature never
makes the same thing twice.

Neither do we. Cast mineral surfaces, each with their own character. Find the one that feels like your space.

Natural colour and texture vary from panel to panel. That’s part of their character.

Illustration of the reuse principle. Construction details depend on your project.

02 / Designed for change

A next chapter.
Not an end.

Spaces evolve. Good materials should be able to come with them.

The surface arrives finished. Screw fixings connect each panel to its supporting frame.

When a space changes, accessible fixings are designed to be undone.

Check the panel’s condition, plan its next installation and give the material a new setting.

03 / The material

Honest materials.
New possibilities.

The colour, the grain, the unexpected detail. It’s all cast into the panel itself. No paper facing. No applied coating.

Born from Diana Saleh’s exploration of better building materials, and a simple question: what if a surface could stay useful as a space changed?

From panel to place / Copenhagen

for change.

A 40 m² interior partition. An Ash finish. A timber frame, with removal considered from the start.
