Cupa R6 - The Pick of Spanish Slates
This is a premium grade, dark grey, non-fading slate with a very fine grain and smooth surface.
Quarries in Spain are required by the government to be identified with discrete numbers. Cupa have many quarries all of which are
referred to by their numbers whereas in other parts of the world they generally have names.Over time we have found that the slate from quarry #6 has performed the best under Australian conditions. The slate from this particular quarry is very consistent, cleaves thin and lies flat on the roof with very few "kickers".
Tests on Cupa R6 have consistently shown no evidence of iron pyrites that are present in many other Spanish slates. The ASTM (American Society of Testing Materials) rating of S1 means the estimated lifetime performance of the slate is 75 years or more. This is a significant achievement for a Spanish slate and one that provides architects great confidence when specifying Cupa 6 for building projects. Photographs of homes with Cupa R6 slate roofs appear in the Case studies - Contemporary Roof section.
There are several grades of slate produced from quarry #6; as in all our products, Bellstone distributes only the top (primera) line which is signified by the letter R. The slates are therefore referred to as R6's.
Cupa R6 slates are produced at the Los Campos quarry owned and operated by Cupa Pizarras S.A, at San Pedro de Trones in the north west of Spain. For technical information on Cupa slates visit their website at www.cupa.es
