Piterak® Slim is a 30mm thick, double-skin terracotta rainscreen cladding system with overlapping horizontal reveals. The system contains a large module terracotta panel available in a variety of standard sizes and a multitude of made-to-order sizes with a maximum height of 2′-0″ and maximum length of 6′-0″. Panels are furnished in lengths required for your project or they may be cut by the installation contractor for specific field conditions.
Piterak® Slim provides excellent structural load performance that is equivalent to thicker terracotta panels while providing a slender profile and minimal material weight. The system provides high wind resistance and the highest (Q4) impact resistance rating under French CSTB (an ICC Construction Product Evaluation Expert Alliance member) standards.
The terracotta cladding panels are supported by our engineered rainscreen support framing system and stainless-steel installation clips. Piterak® Slim is a terracotta cladding system that provides structural versatility and superior aesthetics in an economical rainscreen solution.
