natural slate roofing
NATURAL SLATE THE WIDEST RANGE ON THE MARKET

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.

EACH NATURAL SLATE IS HAND SELECTED BY OUR EXPERT PERSONNEL
DURING THE SELECTION PROCESS, THE SLATES ARE CLASSED INTO FOUR DIFFERENT SELECTIONS

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:

R SELECTION

Our R 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.

natural slate r selection

Our CUPA R 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.

H SELECTION

The H 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 R 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.

NATURAL SELECTION

The NATURAL slate roofing 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.

natural slate eco selection

The NATURAL selection competes on cost with artificial products, but keeps the long life expectancy and low environmental impact that characterises natural slate.

HEAVY SELECTION

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.
 

natural slate heavy selection

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.
