Made-to-order engineered-stone windowsills

A stone windowsill is made as a single piece across the full width of the opening — even a panoramic one. It needs no add-on end caps, does not yellow in the sun and is not bothered by flower pots.

Any opening shape

  • Straight — the most common case, one slab across the window width
  • L-shaped — wraps onto the adjacent wall with no joint at the corner
  • Bay — several angled faces, joined into one surface
  • With a projection into the room: it becomes a desk, a bench or a spot for plants
  • With cutouts for heating pipes and a grille over the radiator

Thickness and edge

The visible thickness is chosen to suit the interior: a thin edge looks lighter, a thick one more substantial. Thickness is built up by lamination, so the weight does not grow in proportion to the look.

The edge can be square, rounded or chamfered. A rounded edge is more practical where the windowsill is at a child's height.

Acrylic or quartz

For a windowsill at a window with direct sun, quartz is the more common choice — it is harder and more abrasion-resistant. Acrylic wins where a curved shape is needed or where the windowsill flows into a countertop and must be one piece with it.
