A Phyllite stone formed within a pre-Cambrian rock sequence around 640 million years old. It has a natural medium grey finish that is free from any pigmentation, making it impervious to the effects of bright sunlight. It is a particularly high-density rock, meaning its hard wearing surface will not take on general atmospheric dirt or scar and pit as a result of acid rain in more polluted environments. Its low porosity also ensures exceptional resistance to the damaging effects of the freeze thaw cycles on the rock.

Features and benefits:

• Available in several machine processed and natural finishes.
• Available in a range of widths and supplied with random lengths.
• CE Marked.
• Denser than most stones, therefore it has a better life expectancy. The low porosity represents a good wearing surface that resists infiltration by polluting articles.
• Achieves extremely low water absorption which is an indicator of its minimal susceptibility to damage during freezing.
• Low likelihood of cracking or breaking when used for external cladding.
• Offers good resistance to the effects of salt crystallisation.
• Offers resistance to thermal shock.
• Subjected to transverse pull-out tests to determine the mechanical and physical behaviour of the stone, deeming it suitable for dimensional cladding.
