CUPA HEAVY 3 - Blue-black natural slate with non-rusting metallic particles and thin laminations. Split to an average thickness of 7.5 mm.
For roof pitches.
Natural blue-black slate with a slightly gritty texture, and in some samples, well-defined parallel lines are clearly visible on the cleavage surface.
A feature of this slate is the presence of metallic cubes of iron sulphide, known as pyrite, approximately 2 mm in size. Sometimes these cubes are randomly distributed throughout the slate, while in other cases they are concentrated in discrete bedding layers. Heavy 3 is the suitable choice for repair and replacement of traditional roofing in Scotland.
