Welsh Heather Blue slate is produced by Welsh Slate and is one of the world’s leading manufacturers of high-quality slate .
From its source near Bethesda in North Wales, Welsh slate has been used and crafted by many generations of people from all walks of life since early Roman times. Penrhyn Quarry has been at the centre and the focal point for UK natural stone and its heritage since the thirteenth-century and a major operation for over 400 years. Indeed Welsh Slate has been exporting to the known world since shipping began and its export markets continue to grow.
The inherent beauty and qualities of Welsh Heather Blue slate have resulted in its specification and use by architects, designers, developers and selfbuilders around the world. The amazing heather blue, or purple colour of the slate is very rare in the industry.
The slate is available on many size and thickness specifications which can be tailored to the required aesthetics of each project. The Capital Grade, as the name suggests, are generally but not exclusively used in the South East of the country, where the very flat and thin 5.5mm nominal thickness is desireable to match what has been historically used on many of the prestigoius buldings of London’s skyline. The County grade at 7mm nominal thickness and the Celtic grade at 9mm are usually preferred further North where buildings are suited to a thicker more pronounced look on the roof.
Welsh Heather Blue is fully tested to BSEN12326-1:2004 and attains A1, T1 & S1 certification.
