Window Sill and Reveal

The horizontal stone under a window, cut to the opening and to the wall it sits in
Cut and finished from Coffee Wood Marble at our own processing base. Typical specification: The sill is the one piece of a window that the weather reaches and the hand reaches, so the decision is the projection and the drip, not the finish. A sill is 20 mm thick, 100 mm to 150 mm deep and 25 mm to 40 mm wider than the opening it covers, and the underside is either sloped to drain or grooved. On this stone the underside is where the figure matters least, so the grain is set to run along the length of the piece.

Window Sill and Reveal, explained

On this stone A standard order on this stone.

The decision you are making

The sill is the one piece of a window that the weather reaches and the hand reaches, so the decision is the projection and the drip, not the finish. A sill is 20 mm thick, 100 mm to 150 mm deep and 25 mm to 40 mm wider than the opening it covers, and the underside is either sloped to drain or grooved. On this stone the underside is where the figure matters least, so the grain is set to run along the length of the piece.

What it looks like

A straight band of brown running along the length of the window, which is the one place the timber resemblance reads as a deliberate line rather than as a wall.

Where it is the right answer

Any opening where the stone is already on the wall — a shopfront, a reception, a hotel room where the reveal is clad in the same material.

On Coffee Wood Marble

Sills are cut from the same slab as the wall they sit under, so the figure on the sill is continuous with the reveal above it. That is the whole point of specifying a sill in this stone rather than in a plain one.

The specifications on these pages are the published supplier and trade-platform figures for Guizhou Coffee Wood Marble, and the decisions each form carries are our own reading of how this material behaves in that job. We have not run a slip test, an abrasion test or a weathering test on any of them. A floor, a path or an external threshold specified for slip resistance needs the tested wet-DCOF figure for the stone and the finish, which we will supply on request.
