CUPACLAD is a natural slate rainscreen cladding system developed by architects, engineers and experts of CUPA PIZARRAS, the world leader in natural slate. The ventilated rainscreen cladding systems consists of natural slates fixed onto proprietary aluminium horizontal profiles, mechanically fastened to an aluminium subframe support.

Why? To adapt a traditional material to the latest architectural trends.
