Riverstone is a stunning phyllite roofing product that delivers outstanding aesthetics and durability. Subjected to incredible heat and pressure over 560 million years, these geological processes make it harder, denser and stronger than any of the alternatives, including slate. This makes it one of the toughest and longest-lasting roofing materials in the world, and is perfect for when you may have a challenging architectural project to design, or you want that truly prestigious green-grey phyllitic sheen finish.Download the Riverstone brochure
Whether it’s as roofing, cladding or flooring, Riverstone graces domestic and commercial buildings all around the world, from America, to Australia, to thousands of homes and businesses throughout the UK.
Due to its premium quality, Riverstone is also one of the few imported slates that has been accepted by Heritage England and Heritage Scotland as an alternative material to use on grade II listed buildings, when a native version is not available. This makes it the perfect choice when you have a heritage or conservation area project where you want the beauty and quality that slate provides, but local planning and building regulations are in place.
Riverstone boasts exceptional durability and water absorption.
Assessed to the US testing standard ASTM C406, Riverstone was awarded an S1 rating, indicating it will last a minimum of 75 years.
What’s more, it achieves the highest possible classification in BS EN 12326 – W1-T1-S1.Contact us
