Manufactured in the UK
Westmorland Green Natural slate has been quarried for over 400 years to create a truly stunning roof covering, that is used throughout the British Isles. The slate provides an appearance of distinction that would grace any home, with its elegant green colour and is quintessentially British and speaks permanence. Natural Slate is renowned for being quarried from Honister Slate Mine or Burlington Stone quarries located near Kirby–in–Furness within the Lake District National Park.
Due to demand overtaking supply and therefore increase in costs and availability of Westmorland Green Slates, Greys Artstone recognised that there would be a demand to provide a genuine alternative, that not only provides a cost saving of around 75% against the natural product, but also replicates identically the random diminishing course roofscape the Westmorland slate deserves, that is also readily available.
Greys Artstone Reproduction slate provides an exquisite finish and provides an identical laid appearance to that of the natural product.
With moulds taken from Westmorland Green Natural Slate originals, the exquisite texture of the reproduction is as essential, as this surface creates the Westmorland Greens distinctive characteristics.
As specialists in manufacturing Random Diminishing Stone slates for the Yorkshire Dales National Park of over 25 years, we provide an easy to lay format to provide not only cost savings on the roofing slates but also in time and labour.
All the slates in our range have been successfully tested for durability, colour, strength, fire and freeze thaw. Many of our competitors use traditional concrete, their slates aren’t protected from the elements, which will expose the aggregate over time. See the example below.
In a recent document The International Glassfibre Reinforced Concrete Association recommend that for good quality GRC, ductile lifetimes of at least 60-80 years can be confidently expected in UK weather conditions. (Source: www.grca.org.uk).
We’re confident our product is durable enough and manufactured to the highest of standards that we give a 25 year manufacturer guarantee.
Colour and Efflorescence COLOUR: Stone and Slate colours on this website are subject to the limitations of monitor quality and are for guidance only. EFFLORESCENCE: The phenomenon of efflorescence has been a problem to the construction industry for decades. The cause lies in the basis chemistry of all Portland cements. Efflorescence in Greys Artstone products is a temporary phenomena and will disappear over time.
