How thick should Coffee Wood Marble be?
Reference photographs. They show the material and the finish; they are not photographs of goods we made, and the colour on screen is not a colour-match.
The figures, and where each one comes from
| Where | Thickness | Why |
|---|---|---|
| Floor, laid as tile | 10 or 12 mm | The substrate carries the load and the thickness only has to survive handling |
| Floor, laid as slab | 18 or 20 mm | The slab spans itself and the substrate only has to be flat |
| Wall panel, mechanically fixed | 18 or 20 mm | The panel is the stiffest thing in the wall |
| Counter, stair tread, visible edge | 30 mm | The edge is the part that is seen and the part that is hit |
Why it behaves the way it does
Thickness follows the way the stone is held. A tiled floor is held by the substrate and can be thin; a panel is held by itself and has to be stiff enough not to crack on its own weight and its own handling.
What these figures are, and what they are not
These are the thicknesses we supply. The thickness that a specific floor needs is a question for the engineer who designed it, and the tolerances are ours to state on the order.
If you are specifying this
We have not published products against this question yet. Send us the process, thickness and quantity and we will quote it against what we can actually form, rather than against a catalogue.
18 or 20 millimetres for a floor or a wall panel, 30 millimetres where the edge is seen or the surface takes a hit, and 10 or 12 millimetres where it is tile on a sound substrate. Twelve millimetres is made to order for a substrate that cannot take more.
