Estillo 3 has a very deep blue grey to blue black colour. The excellent working characteristics of this slate mean that it splits well, whilst vigorous sorting at the quarry into 3 thickness grades produces excellent selection for a heavy, textured slate. This gives the roof a neat finish, without having to sacrifice on traditional slate character.
Specially hand split as a thicker roofing slate, the extra depth adds character to the buildings it covers as well as providing the essential extra protection that the harsh climate demands of the UK.
The slate is very clean and virtually free of pyrite and other inclusions.
The slate is fully tested to BSEN12326-1:2004 and attains A1, T1 & S1 certification.
