This ultra-light material is resin-free 100% concrete. Installing in minutes using only carpentry tools and customizable to any design layout. Concrete is a breathing material with all its inhomogeneous surfaces and cloudy appearances, and architects love it so much. Being a hygroscopic material, moisture is absorbed and released from concrete as the surrounding humidity changes. Efflorescence is a specialty of all cement-bonded materials and is a natural and entirely harmless feature of concrete. Panels can be installed with metal anchor or simply glued (small formats only). Durable, they provide excellent thermal and acoustic insulation, and they are fire and water resistant.
