Premium Clay Board, 12.5 mm
Optimal protection for living and workspaces
This clay panel sets new standards for interior walls in modern architecture. At just 12.5 mm thick, our panel offers 56 dB of sound insulation—twice the performance of conventional 16-mm panels—and creates a very comfortable indoor environment. Weighing only 17 kg, it is easy to install and, thanks to its high material density, is exceptionally sturdy and durable.
Ideal for new construction and renovation, it offers a natural living environment, efficient thermal and sound insulation, and flexible application options—an innovative solution for demanding construction projects.
