Application

For roof pitches.

Description

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.


Features and benefits:

  • Impermeable to water.
  • Weather and UV-resistant.
  • Chemical-resistant - not affected by chemicals or pollutants (acid or alkali).
  • Not damaged by fungi, moss, insects, animals or birds.
  • Strong, while weighing substantially less than man-made roofing tiles.
  • Non-combustible.
  • Metallic cubes on the surface.
