Ventilated façades are high-performance solutions for building exterior cladding. The air cavity between the wall and the façade cladding improves thermal insulation and moisture protection, while porcelain stoneware slabs in sizes up to 160×320 cm ensure strength, long-lasting durability and design continuity. The S1 System is a concealed fixing solution for 6 mm and 9 mm slabs, certified with the important ETA approval.
