Cupa Heavy 3 has the appearance of a traditional Ballachulish slate in 8-10mm thickness, heavily riven, with a rugged teture. This slate has been used for generations in Northern Spain, where temperatures can vary from +35 degrees in summer to -20 degrees in winter, making it ideally suited to the harsh Scottish climate. Architects have recognised the fact and this is why the Cupa Heavy 3 now cover many of Scotland's new and historic buildings. The slate carries a 100 year quarry and insurance backed guarantee.
Galicia Grade A is produced from the same slate deposits as the Heavy3, specifically for the Scottish market at 7-9mm thickness. It has a less rugged texture, but the same durability record as the Heavy3, making it an economical choice. It also conforms to the highest European standards and is subject to the most stringent quality control procedures. This slate carries a 30 year quarry and insurance backed guarantee.
