GoBoard Accessories - GoBoard Curb

GoBoard® Curb is a block-shaped tile backer board profile from Johns Manville. GoBoard Curb is designed to provide a thick block-like underlayment profile for use in fabricating the curb of the shower pan. Multiple curbs can be placed next to each other for larger shower areas. Like the original GoBoard, it's engineered for durability, yet is up to 80% lighter than other building materials typically used to fabricate shower pan curbs.
