Permarock® cement boards are engineered for modern drylining and thrive where moisture tries to win. Built from inorganic materials, they resist mould and mildew in the toughest wet zones - pools, steam rooms, and communal showers - while staying lightweight and easy to handle. Take it outside and deliver reliable stability to façades, exterior walls and soffits and suspended ceilings, arcade walkways, underpasses and driveway passages, pairing weather resistance with low weight. They curve cleanly for expressive forms, accept a wide range of finishes, and help build durable, imaginative spaces.
