One third of all slate in the world comes from CUPACLAD's 16 quarries in Spain. Every slate panel is unique giving an unparalleled character to any project remaining unaltered for many years. It is a natural product of superior technical properties that also adds value to any project. CUPACLAD is the perfect alternative for an efficient and sustainable cladding. Used since roman times, natural slate is long–lived, remarkably durable, fire resistant and naturally waterproof. Its aesthetic and technical properties remain unaltered, keeping the elegance and character for much longer than any man made alternatives.
