The Stoneleaf Celtic Sea Green
The Stoneleaf Celtic Sea Green natural roofing slate is hand-split from robust, finely grained metamorphic rock. Its distinctive green colour and textured surface will produce a roof finish with depth and distinctive character.
Ideal for both new build and refurbishment projects, the Stoneleaf Celtic Sea Green is a cost effective option for specifiers, developers, roofers, private homeowners, and conservation officers where the local environment would benefit from a slate of this texture and colour. It can also be used as a suitable replacement for the Westmorland Green Slate.
Achieving top rating A1, T1, S1 in the European Test BS EN 12326-1:2014 for Water Absorption, Thermal Cycle and Sulphur Dioxide Exposure, Celtic Sea Green is suitable for use in all construction environments.
