Description
• Top grade Spanish natural slates.
• Smooth surface texture and consistent thickness.
• No discolouration risk.
Duquesa slate is a tough natural material and samples are regularly tested to the following national standards:
British Standard.
BS EN 12326-1:2004 Product specification for roofing slate.
• Exhibited the top Class A1 for water absorbtion.
• Exhibited the top Class T1 for thermal cycle resistance.
• Exhibited the top Class S1 for sulphur dioxide exposure resistance.
• Good flexural strength both transversely and longitudinally.
• Acceptable non-carbonate content.
Most slates have a secondary plane of cleavage or grain which can only be determined microscopically.
However this grain should not be confused with the texture which can be seen on the surface of the slate which is influenced by the direction in which the slate is split with a chisel, either from the top or the side.
Duquesa slate has a normal texture using the classifications detailed in BS EN 12326, and consisitent thickness, between 4-6mm, which will contribute to an even looking roof slope.
