SELECTIONS | NATURAL SLATE
At CUPA PIZARRAS we extract natural slate from 16 quarries and we work transform them in our 22 industrial units, where the most advanced technology combines with our craftsmen’s traditional know-how.
All the natural slates that bear our brand have been produced directly in our quarries and, therefore, are subject to our quality and environmental management policies, as well as our unique traceability system.
Once the cutting and working process is complete, the slates are selected one by one by our quality team.
OUR SELECTIONS | NATURAL SLATE ROOFING
The various technical and aesthetic criteria of the natural slate are considered during the manual selection process. This categorisation is made mainly based on their flatness and thickness, allowing the slates to be classified into four different selections:
Our EXCELLENCE selection of natural slate is the result of an extraordinarily rigorous classification process that is only passed by slates of great flatness and very regular thickness.
Our CUPA EXCELLENCE slates are considered to be the best natural slates produced in the world by thousands of architects, installers and individuals and are used in projects where a homogeneous result is sought for a perfect roof.
|EXCELLENCE||3.5 - 5mm|
The ARDOISIER natural slate selection features high quality, permitting slight variations in slate thickness and flatness.
The technical characteristics of the slates – their strength and durability – are the same as in the EXCELLENCE selection, as they are produced from the same natural slate blocks. These slates are chosen by experienced installers who are able to adapt the product to the roof and guarantee a homogeneous result.
|ARDOISIER||3.5 - 5mm|
The NATURELLE natural slate selection is made up of slates that allow greater variations in thickness and flatness. The technical characteristics of the slates are the same as in the superior selections, as they are produced from the same natural slate blocks.
The NATURELLE selection competes on cost with artificial products, but keeps the long life expectancy and low environmental impact that characterises natural slate.
|NATURELLE||3.5 - 5mm|
Our HEAVY natural slate selection is made up exclusively of thick slates, of over 7 millimetres, characterised by their exceptional durability in any circumstance or climatic conditions.
While they come from the same blocks, unlike the other selections, the HEAVY selection is produced looking for greater thickness and more texture in the natural slate. The result is a slate with a crafted appearance and unmatchable strength that gives a roof a unique personality.
|HEAVY||7 - 9mm|
OUR SELECTIONS | NATURAL SLATE CLADDING
SELECTION, CLADDING SPECIAL
Our special cladding selection is made up solely of slates of great thickness, 7.5 mm, characterised by their great regularity and flatness.
Special cladding natural slates are selected from among the 16 quarries for their durability and they are subjected to wind, bending and impact testing to guarantee exceptional performance in any cladding project.
The special cladding selection is the product chosen for all our rainscreen cladding systems in CUPACLAD® natural slate.
