Etex Cedral Thrutone Smooth Fibre Cement Slates are a Low-Profile Fibre Cement Slate. These are manufactured by Etex Group Ltd and were formerly known as Marley Eternit Thrutone Slates.

The standard size Roofing Slate is 600mm x 300mm which is used over the whole roof area. You would use a Thrutone Double Slate 600mm x 600mm to achieve a staggered bond effect across the roof area which is a must in order to achieve a waterproof finish.

The Thrutone slates feature a smooth surface with square cut edges for a sleek, aesthetically pleasing roof finish. They are particularly suitable for complex roof geometries and are one of the strongest slates on the market.

These slates are particularly favoured by Architects and Professional Roofing Companies.
