Room divider
Premium Clay Board, 12.5 mm
This clay panel offers excellent thermal and sound insulation, as well as a lightweight design.
At just 12.5 mm thick, it provides the same sound insulation as two 16-mm panels (56 dB). Weighing 17 kg per panel, it is noticeably easier to work with and can be quickly installed in drywall construction.
The high material density ensures stability and durability. The product is ideal for interior walls, cladding, and attic conversions, both in new construction and renovation projects.
