Slate’s characteristics make it the ideal natural choice to protect your home. Our slate window sills are durable, with high resistance to acid and alkali. The surface is impervious, meaning water will not penetrate, ensuring the material is protected from frost damage, giving you and your home the protection it needs against the harsh British weather.

Specifications & Options
Joggles
Slate window sills manufactured to your specific size and shape. We precision cut our slate to suit your window opening with an optional wrap around joggle to each reveal. Horns are cut in to each slate end so that it sits nicely in to each opening, and rendered. We do not recommend joggles for a stone clad build as the slate will sit inbetween each reveal.
Profiled slate sills
Manufactured to your specific sizes, we precision cut and profile our slate to suit your project. Our profiled slate sills are all bespoke made with a seat or flat top for your window to sit on and a machined slope so the weather will not penetrate your home, with a fluted drip groove as standard. In order to produce this product we do recommend a minimum of 50mm thickness.

Standard Sizes
Regarded as the most cost effective solution to your build, our plain straight slate window sills are available in most widths and lengths; rectangular in shape with a good choice of thicknesses. There are two types of finishes, a riven/cleft finish, or a smooth fine rubbed surface; all precision cut to your bespoke window or opening sizes.
