Penrhyn Heather Blue 'Bangor Blue'

Penrhyn 'Bangor Blues' are the best quality natural roofing slates in the world. Extracted from 590 million year old deposits in Bethesda, North Wales, this slate is known as the 'Rolls Royce' of roofing materials.

Penrhyn slates have an attractive heather blue or purple colour, and come in standard sizes of 500×300mm. These slates are cut by a multi-blade process and produce one 8mm grade of slate. This unique machine-cut extraction manufacturing process ensures that each slate is uniform.

Penrhyn slates fully conform to BS EN 12326: Part 1: 2004 and Welsh//Slate was the first slate company in the world to achieve ISO 9002 accreditation.

Penrhyn slates are generally expected to outlive the life of a building (when fixed in accordance with BS 5534 and BS 8000), and are covered by a 100 year quarry backed guarantee.
