Dalhem Ribba utilises a gypsum particleboard core chosen for its resistance against fire and stability. The gypsum core can be wrapped in either natural wood veneer of in a foil finish chosen from timber effect/solid melamine or metallic colours.

The product is for ceilings, wall paneling &
balustrades etc., with slat sizes, spacing & timber type to be specified by the client.

Veneers can be stained or oiled to match existing surfaces such as floors or furniture. Dalhem Ribba slatted timber walls and ceiling products enable the designer to introduce warmth and character with a functional role. The prefabricated
modular nature of the products construction allows a fast and accurate installation process.

Fixing methods allow for fixed and demountable systems to be integrated into the product. The nature of the product allows slats to be set out around the services, if required and co-ordination to integrate, light fixture, sprinklers, access panels etc. Endless possibilities for interior design on walls and ceilings, the piece by piece installation allows for infinite increments of gaps between ribs as well as easy integration of lighting elements.

Dalhem Ribba wall and ceiling ribs are installed individually. Standard fixings on concave/convex curves from a radius of 500mm for ceilings or 150mm for walls – dependent on both rib depth and spacing between ribs.
