Earthquake resistant

CUPACLAD systems have been specifically designed to resist structural movements without cracking, providing stability and security to the building. 

One of a kind

Each slate is unique. Its texture tells us the story. Created by all the natural forces and made up of many different minerals. No other artificial alternatives could compare with a product which has been molded by nature for over 500 million years. 

CUPA Pizarras has, since 1892, had the privilege of offering the world slates from a unique land, the result of thousands of years of work by nature itself.


With a durability of over 100 years, natural slate is the most resistant material used for roofing. Unlike the artificial products, the color, and the properties of slate stay, unalterable through time with no need of maintenance. 

Natural Slate

The CUPACLAD system was created to fill the need to adapt natural slate to new architectural trends, which call for more ecological and sustainable construction. 

Slate is a completely natural product with unbeatable technical properties that provide considerable added value to any façade project. 

Slate is a product with unmatchable technical properties that adapts to any project, always providing considerable added value. 

Natural slate gives a timeless unchanging appearance. Its elegance and personality confer a unique character. 

Impact resistant

CUPACLAD can withstand damage from impacts, guaranteeing a perfect performance even in the most exposed areas. 


By being 100% natural, slate is the roofing material with less environmental impact. Each slate is handcrafted by our skilled splitting craftsmen with no chemical products or additional treatments added.
