What is the weight of a Coffee Wood Marble floor compared to a timber floor?
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
| The floor | Weight per square metre |
|---|---|
| Coffee Wood Marble, 20 mm slab | about 54 kg, before bedding |
| Coffee Wood Marble, 18 mm slab | about 49 kg, before bedding |
| Timber floor on joists | Much less, and it is carried by the frame rather than by the slab |
| What it decides | The structure, the lifting and the fixing |
Why it behaves the way it does
Stone is a structural material and timber is a finish, and that difference is the reason a stone floor needs a flat base that can carry it while a timber floor needs a frame that can carry it. It is also the reason a stone floor cannot be fitted to an existing soft floor.
What these figures are, and what they are not
The weights are calculated from the density this stone is published at. They do not include the bedding, the adhesive or the finish, and a specific floor's build-up is the engineer's figure.
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.
Substantially heavier. A 20 millimetre marble slab at 2.70 grams per cubic centimetre is about 54 kilograms per square metre, before the adhesive or the bedding, against roughly 15 to 20 for a timber floor of the same build-up.
