Slate Types
 Cupa Heavy 3 is a unique slate produced in the same quarry as Cupa 3, but is split to a thickness of 8-10mm. It is specially produced for the Scottish market as an alternative to Ballachulish slate, but is also ideally suited to Ireland’s landscape and Atlantic climate. Heavy 3 is suitable for commercial projects (see Lough Erne Golf Resort, Enniskillen) and residential developments (see Cedar Park, Co. Mayo). Its ability to combat dampness also makes it a favourite for conservation projects throughout the UK. Declaration of Conformity www.cupaheavy3.com |

 Cupa 12 is a grey slate with a smooth matt surface. It is noted for its exceptional consistency of thickness and surface appearance.

Cupa 12 is split to an average thickness of 4 and 6mm in several formats including rectangular, square, half moon, schuppen and fischuppen. Declaration of Conformity |
