Window sills and thresholds Connecting outside with inside

Gneiss allows you to draw a natural line between the diversity of the outside world and the desires that take their own forms in each house. Window sills and ledges are available with natural split or machined surface. Dimensions and thicknesses, visible edge processing as well as making of a water drainage and/or groove are adapted to the customer’s wishes.
