Promotion: Spanish company Cupa Pizarras has developed Cupaclad, a facade cladding system made from slate that aims to provide a sustainable alternative to conventional exterior finishes.

The Cupaclad system was created by Cupa Pizarras to showcase the material's design merits, from its recognisable grey colouration to its insulation properties.

The raw slate used for the Cupaclad system is mined out of 20 quarries located across Spain, all of which are owned by the company. An additional 24 processing plants handle the slate and ensure it is ready for application.

Cupaclad was designed to have a natural, clean aesthetic that aims to adapt to any style of building, from the traditional to the contemporary.

Regardless of the building's design style, the system caters to modern standards of energy efficiency and sustainability, according to the company.

"Natural slate is a mineral product, and its production process from quarry to installation is highly efficient and does not employ any chemical products," said Cupa Pizarras.

"[We offer] a natural product which has less environmental impact than any other alternative materials for roofs and façades."

In addition to acquiring and processing the stone for the system, Cupa Pizarras has an in-house support team ready to aid designers and architects at each stage of the project, from initial ideation to installation on-site.

Projects that utilised Cupaclad include an A-frame house in Angers, France, and a house on Costa Street in London that has an extruded roof clad in slate.

Cupa Pizarras has supplied slate cladding for larger-scale projects too, including for the monolithic Cache County Public Works facility in Utah, USA.

The cladding was also used in the design of the College of Engineering, Technology and Aeronautics (CETA) in New Hampshire, USA, which comprises two buildings with dramatically pitched roofs covered in slate.

Cupa Pizarras is a natural slate company that was founded in Spain in 1892. Its products have been used in projects across 60 countries and five continents.

The company has branches in a range of locations including in the UK, USA, France and Denmark.
