Calibrated Brazilian Slate Sills


We offer a full range of standard slate sill sizes and thicknesses, from 25mm up to 40mm.

You can choose to have your sills finished with a Straight or a Pencil Edge and the option for a drip groove in the underside.

Choose from either a polished or lightly riven finish, making it easy for you to achieve your look.

We can also offer bespoke slate sills, cut and finished to your specific requirements at a minimal cost.

Slate window sills provide a weather-repellent area for the base of your window and look fantastic both inside and out.
