What Is the Most Popular Spanish Slate in the UK?

The Ardigonte Spanish Slate:

The Ardigonte Spanish Slate is a Premium First Grade Slate mined in the quarry rich Northwest region of Spain. Sharing a lineage with many other popular Spanish Slates, the Ardigonte has proven to be a popular choice amongst homeowners due to its classic Blue/Black colour and flat appearance.

With an average thickness of 4-5mm, the Prime Grade Ardigonte is perfectly sorted, each slate being flat and of consistent appearance. This offers a much cleaner and more uniform cadence to your roof, as opposed to traditional slightly more Chunky Spanish Slates. This also means that the Ardigonte is very easy to work with for roofers and builders installing them. Its thin nature makes it easy to cut and the consistency means that they will lay flat, ensuring a quicker install time without the need for rearrangement or a lot of attention. This saves costs on both Labour and Materials.

The Ardigonte Slate can also feature elements of Stable Pyrite in it. Lots of homeowners and roofers get concerned when they hear that a Slate has Pyrite. What is important to note is that there are 2 types of pyrite, stable and unstable. The Ardigonte Slate, being a Prime Grade, will only ever contain small traces of stable Pyrite, concentrated in tiny areas on the Slate. This Pyrite is naturally occurring in the Slate Rock and totally unavoidable. This type of Pyrite has absolutely no effect on the quality or longevity of the Slate.
