Products
The 101 series uses concealed stainless steel fixings, allowing the natural beauty of the slate to take center stage on the facade. Available in three distinct layout patterns:
A clean, uniform layout that puts the texture and natural sheen of the slate front and center. The go-to choice for projects that call for a refined, understated facade.
Combines varying slate sizes to create a dynamic, organic composition. Ideal for projects seeking visual movement and a more expressive facade character.
Aligned joints create a homogeneous, grid-like composition that emphasizes the unique personality of each slate piece. A strong choice for contemporary, geometry-driven designs.
The 201 series features exposed stainless-steel clips designed to blend with the natural slate, significantly reducing installation time compared to other ventilated facade systems.
Large-format slates paired with visible stainless-steel clips create a clean, modern aesthetic. The fastest CUPACLAD installation system — ideal for projects where schedule is a priority without compromising on the authenticity of natural slate.
Sustainability
Natural slate requires no chemical treatments, no artificial materials, and no furnaces to produce. Life cycle analysis confirms natural slate as the ecological option for facade cladding — with significantly lower water consumption, energy consumption, and atmospheric pollution than fiber cement, zinc, or clay alternatives.
CUPA PIZARRAS holds ISO 14001 environmental certification — pioneers in the natural slate sector in obtaining this standard — and carries a BRE Global Verified EPD, independently confirming the full life cycle environmental performance of their slate.
Natural slate is classified as noncombustible under ASTM E136, requiring no additional fire treatment and introducing no toxic byproducts. Once installed, CUPACLAD requires zero maintenance and zero replacement for the life of the building — eliminating the embodied carbon cost of material cycling that manufactured facade products inevitably carry.
Over 60% of CUPA PIZARRAS production uses marine transport — the lowest-emission freight mode available — and closed-loop water recycling systems at all quarries minimize water consumption throughout extraction and processing. Exhausted quarries are restored through hydroseeding of native plants, ensuring full ecological recovery of the site.
