Slate Sills

Welsh Slate is an ideal material to produce sills, each individually manufactured to the client’s bespoke specification.

Sills can be flat, weathered or profiled and the fall can be varied to suit the design specification, with drip grooves, edge details and weather bars added during manufacture. Standard flat sills up to 1600 mm long and 300 mm wide in 20 mm and 30 mm thickness are available in Sawn, Brushed and Honed finishes. Smaller units up to 1000 mm in length are available in the Natural Riven finish. All meeting the highest requirements of the British Standard BS5642 Class A.

Available in both Penrhyn Heather and Cwt-y-Bugail Dark Blue Grey they bring a detailed finish to refurbished and new-build commercial and residential properties.



Welsh Slate sills are supplied to your bespoke specifications
