THE CHARACTER OF THE SURFACE
Flexible sheets combine a thin natural stone face with a composite backing. The surface retains its mineral pattern, while the sheet's construction opens up possibilities for walls and furnishings. The choice involves colour, format and backing type, as well as thickness.
FLEX and EXTRAFLEX do not bend in the same way; translucent versions are intended for backlighting effects. Define the detail you want to achieve and check the information for the exact version, without transferring instructions from one sheet to another.

FROM THE MATERIAL TO THE WALL
Sheets sold individually; dimensions, joints, cuts and backing vary by version.
These are not solid stone slabs: the stone is a veneer on a composite backing. FLEX, EXTRAFLEX and translucent versions behave differently; check bending, joints and limitations near heat sources.

No. The face is a natural stone veneer applied to a resin/polyester and fibreglass backing; the category information also mentions PVC. This composition must be distinguished from a solid stone slab.
The catalogue distinguishes the two types: FLEX for curved surfaces without sharp angles, EXTRAFLEX for more pronounced bending details. Check the variant's radius and application method with the supplier.
The product information describes a stone veneer on a translucent backing with an onyx-like veined effect. It is not correct to identify them automatically as natural onyx slabs.
