Natural roofing slate
A private art gallery in Betws Y Coed in Conwy, Wales, has been roofed using Cupa R4 natural Spanish slates from Cupa Pizarras. The product was chosen as the gallery required a slate that was sustainable and would be a suitable fit to the existing environment. The 50cm x 25cm slates were used and secured to the tiling battens with copper nails.

Natural slates
Cembrit’s Alpina natural slates have been used for the redevelopment of an award-winning holiday park in north Devon. The product was chosen as the material was required to harmonise with the coastal surroundings. Approximately 35,000 Grey/Green Cembrit Alpina natural slates were installed on the multi-pitched roof. The company used the hook fixing method to secure the slates and lock them together tightly to achieve a neat finish.
