The wave-like hollow core visible at the edge helps make the boards lightweight and acts as a sound-trapping barrier. With a ceiling-and-wall buckle mechanism, construction teams can snap these panels together efficiently and create a continuous surface. With waterproof and fireproof capabilities, this cladding supports visually appealing, quiet, and safe interior environments on time and under budget.
