Venta 30 Spanish roofing slate is ideal for residential properties, supermarkets and commercial properties and is suitable for the Scottish market.
Venta 30 Spanish slate has a very textured appearance and has a nominal 7-9mm thickness, creating a very rustic, traditional appearance. This slate, which is predominantly black in colour with some shade variations, is very easy to grade and lay on the roof and is sourced directly from the slate quarry.
This slate is regularly tested ensuring that it conforms to relevant British and European standards. This slate is in constant production meaning there is excellent availability. Venta 30 is holed at the quarry meaning there are fewer breakages on site.
