As the name suggests the Zamora slate is quarried near the town of Zamora in the Galicia region of Northern Spain. It is surrounded by some of the most famous slate quarries that Spain has to offer. This quality slate is highly sought after, due to its versatility and durability, making it the ideal product for more difficult roofing designs that require large amounts of cutting and detailing.
The Zamora exhibits a blue/grey colour with a small amount of mineral inclusions giving it a unique character when in situ. It has a light textured surface with medium dressed edges.
The Zamora Ultra-Grade is available in a 5mm thickness.
Ultra-Grade slates are of the finest quality and are produced from specially selected blocks extracted from the quarry. Ultra-Grade slates give a superior finish in terms of flatness and uniformity with minimal sorting and grading needed on site prior to fixing.
Sizes available: 500x250mm
The Zamora Ultra slate boasts a W-1, T-1, S-1 rating, meaning it conforms and surpasses all the top UK tests for water absorption, thermal cycle resistance and sulphur dioxide exposure.
If further technical information is required ISS hold the declaration of performance (DOP) for the Zamora which can be provided upon request. In addition the Zamora conforms to the NF European certification.
