Cambrian Slates embody the beauty and character of natural slate. Made in Wales from over 60% recycled Welsh slate, Cambrian tops the range in both looks and performance and has a proven track record even on pitches as low as 15°. Whilst light in weight, Cambrian's unique three point fixing makes it suitable for even the most exposed sites.


As there is no British standard for Cambrian Slate, it has been designed to meet the relevant performance requirements of BS 5534: 2014 Code of practice for slating and tiling (including shingles). Cambrian has been awarded British Board of Agrément Certificate 87/1907.


Cambrian Slates have been rigorously tested in our wind tunnel where combinations of high wind and driving rain are used to determine the slates performance with respect to wind loading and weathertightness. Cambrian Slates will meet the requirements of BS 5534: 2014 Code of practice for slating and tiling (including shingles), providing our fixing recommendations are complied with.
