Description

Penrhyn Welsh Slate roofing is quarried from Bethesda, Bangor on the edge of the Snowdonia National Park, North Wales. Penrhyn slate is generally heather blue in colour; with a limited availability of a red shade. The slate is naturally split along cleavage planes created by over 590 millions of years of intense pressure and heat to produce extremely strong roofing slates with a riven surface.


In addition to traditional rectangular patterns, Penrhyn slates can be shaped to agreed templates. Slates can also be supplied in large sizes up to 1000 mm in length in both fixed size and random diminishing courses.


Features and benefits:

  • Conform to BS EN 12326-1: (A1, S1, T1).
  • Hold BS Kitemark accreditation and have a proven durability of in excess of 100 years.
  • Available in 5.5 mm, 7 mm and 9 mm thickness.
