Slate is a metamorphic rock formed from the transformation of clay under high pressure and temperature. Very homogeneous and sober, with shades ranging from dark gray to black, it is commonly used in floors and roofs due to its durability and appearance. Slate also works very well for façades, combining the aesthetics of natural stone, shaped by nature for over 500 million years, with the thermal comfort and ease of installation of ventilated façades.
