Product Details

Benuza Blue Slate: 40cm x 25cm (16" x 10")

Benuza Blue slates capture the colour, appearance, and weathering characteristics that of a traditional Welsh Blue slate. Imported directly from the quarry by Ashbrook Roofing, these hard-wearing slates are quarried in La Bana. This is the same region as the other great natural Spanish slates. (Forna, Del Carmen and Matacouta).

Spanish slate is famous the world over. The very 'best of the best' are quarried in a small region of northwest Spain called La Bana. Here the best quarries produce a particularly strong and easily worked slate. It is renowned for its strong vertical grain that runs along the length of the slate.

This beautiful soft blue-grey roofing slate is equally suitable for use on contemporary, town, or country properties. Many customers choose Benuza Blue Slates where they are particularly trying to capture the traditional feel and quality of a slate roof. Others choose Benuza slate where quality and good looks are a priority.
