Description
Kentdale Blue Grey is a beautiful mid blue grey slate with a true, non shiney “natural slate” texture which is very reminiscent of our own indigenous slates. The reserves which the quarry work are regarded as some of strongest and hardest in the region. This Quarry has been extracting and exporting slate around the World for over 40 years now. The company produces over 3.7 million mtr2 of slate roofing per year.
The raw slate is a true slate which has undergone the metamorphic process of physical and chemical changes within its structure due to the heat and pressure encountered since it was laid down in the Ordovician Period over 400 million years ago. This gives the finished roofing slate the strength and durability to withstand the rigours of protecting us from the elements. It also give the slates the distinctive rugged texture and allows the slating contractor to work with it in a very traditional manner. The quality of the slate has been recognised by a number of local and special planning authorities around the UK who approve of this slate as a high quality cost effective alternative to traditionally used slates without compromising on the finished aesthetics of the project.
Slate Testing
The producers are very quality conscious and the slate is regularly and rigourously tested to the current BSEN12326-1:2004 and attains A1, T1, and S1 certification.
Every crate bears the current testing data along with a production reference which allows for traceability from the quarry face through to delivery to site.
