Rumett Mineral Panel

Product

A cast mineral wall panel for interior fit-out. The panel is solid mineral. Colour and surface variation are created during the casting process rather than printed or applied, and the surface is formed at the point of casting rather than built up on site.

Composition

Gypsum and bio-ash, cast together, with no cellulose reinforcement. The bio-ash is clean ash from wood-pellet combustion, within the limit values for heavy metals. The composition is described in the DBI classification report.

Applications

Interior wall surfaces in fit-out, fixed to a supporting framework built from standard components available on the market. The panel is a cladding panel and is not load-bearing. For anything outside interior wall cladding, send us the specifics of the project and we will confirm suitability.

Reaction to fire

The classification applies to the product defined in the report. Coverage of sealed or lacquered variants remains to be confirmed.

Reaction to fire and fire resistance are different tests. This classification addresses reaction to fire only, and is not a fire resistance rating. It is a classification, not a certification or type approval.

The classification report is available on request.

Format, thickness and weight

Panel thickness is 13 mm. Panel format is set per project rather than offered as a fixed catalogue size, because panels are cast to the project; panels are cast up to 1,200 mm long. Tell us the wall and we will confirm the formats available for it.

A dry 13 mm panel weighs approximately 16 kg/m².

Surfaces

Six finishes: Lime Stone, Ash, Gypsum Sand, Desert Sand, Rosso Sand and Travertine. Bespoke colours by agreement. Panels are supplied untreated or sealed, by agreement.

Fixing and installation

Panels are fixed mechanically, with screws into a standard stud system available on the market, rather than bonded with adhesive. Screw heads are covered with material from the same casting, so the surface reads unbroken.

This is Rumett’s current practice rather than an engineered installation specification: for each project we confirm the panel format, the framework type and spacing, the screw type and position, edge distances and any loads to be hung on the wall, with the project’s engineer where one is appointed.

Disassembly and reuse

The panels are screwed rather than glued and are designed for disassembly; this has been documented. Panel material has also been reused in a new production batch, which is documented as well.

Reference data

How to cite Rumett in a specification

Use the current project documentation rather than copying values from old presentations, emails or search snippets. At minimum, cite the product name, composition, nominal thickness, fixing principle, finish, project format and the specific documentation issued for the project.

For fire, cite the EN 13501-1:2018 reaction-to-fire classification within the scope of the DBI report, and request the report for the exact scope before specifying.
