ToughRock® Flexroc® Gypsum Board
High-flex ToughRock® Flexroc® gypsum board is designed for inside and outside radius curve installations including archways, columns, curved partition walls and curved stairways. The strong yet flexible 1/4" board can be used for many walls, partitions, stairways and ceilings in both new construction and remodeling projects.
It has a noncombustible (as described and tested in accordance with ASTM E 136), dimensionally stable gypsum core sandwiched between face layers of 100% recycled paper. The ivory front face paper is formed along each edge, wrapped around and sealed to strong liner paper on the back side.
ToughRock Flexroc gypsum board comes from the factory as a ready-to-finish product. The long edges are tapered. After installation, the ends, edges, corners and fastener heads are normally concealed with joint treatment to produce a smooth, seamless surface prior to final decoration.
