The bulk of our slate window sills are now sourced from Brazil. They are grey/black in colour with a naturally smooth surface and square sawn edges. The sills are all calibrated to specific thicknesses for ease of installation and better aesthetics. We have an extensive stock of differing thicknesses, lengths and widths which fulfil most requirements. However, we do also offer a cutting and machining service for any bespoke specification. 

All of our slate sills can also be utilised as wall copings and with lengths of upto 2.2 metres, cutting and material waste can be kept to a minimum.
