Our 20mm Riven Slate Window Sills offer a natural, textured finish that brings character and authenticity to both traditional and contemporary interiors. Produced from high quality natural slate, the riven surface provides subtle variation in texture and tone, creating a distinctive, timeless appearance.

Each window sill is custom cut to your exact measurements, with lengths ranging from 300mm up to 2000mm and depths from 90mm to 900mm, ensuring a precise, made to measure fit. All pieces are fabricated using precision cutting methods to maintain clean edges while preserving the natural riven surface of the slate.

You can customise your window sill by selecting which edges are to be finished, including the front edge and optional left or right returns. For installations that require additional detailing, there is the option to include specific fabrication instructions, such as recessed polished edges or bespoke shaping, allowing the sill to be manufactured to suit your exact requirements.

All riven slate window sills are sealed prior to dispatch, enhancing durability and providing added protection against everyday moisture and staining while maintaining the natural appearance of the stone.

Frequently Asked Questions

Can I order custom sizes?

Yes, all of our window sills can be made to your exact measurements. Simply enter your dimensions when ordering, and we’ll cut and finish each piece to your requirements.

What materials are available for your window sills?

We currently offer quartz and slate options on our website. However, if you email us, we can provide many more materials, including granite, marble, and other natural stones, tailored to your project.

Are the window sills sealed before delivery?

Yes – all exposed surfaces are sealed before leaving our workshop to provide added resistance to moisture and staining. For natural stone, we recommend resealing periodically to maintain performance.
