Tile Backer Board

GoBoard® by Johns Manville is an ultra-lightweight, waterproof and durable tile backer board that is easy to cut and install. GoBoard is engineered and tested for strength and durability, yet can be cut right where it’s installed using a utility knife. Plus, it's up to 80% lighter than traditional boards. Installation time is reduced because waterproofing is built-in, eliminating extra steps since only board joints and fastener locations need to be sealed.
