Guarantees for up to 100 years 40 years’ expertise World-class natural slate Uncompromising quality standards Phyllite: 560 million years in the making Phyllite is a type of metamorphic rock, that forms when shale is subjected to incredible heat and pressure for hundreds of millions of years underground. The resulting material is an outstanding natural stone that’s perfectly suited to roofing, flooring, cladding and much more. Harder, denser and stronger than slate, or any of its other competitor materials, phyllite nevertheless splits easily during processing, and the mica particles on its surface give it an unmistakable ‘phyllitic sheen’. Find Out More Phyllite thrives under pressure Phyllite is the result of similar geological processes to the ones that produce other natural materials like slate – except phyllite undergoes even higher temperatures and greater pressures. That causes the clay present in the material to break down and form mica, which is responsible for phyllite’s satin-like lustre.
