SHEETROCK® Glass-Mat Mold Tough®

USG Boral SHEETROCK® Glass-Mat Panels Mold Tough® are high- performance interior panels for new construction or renovation work. The panels have a non-combustible moisture- and mould-resistant core encased in a moisture-resistant non-woven glass mat that repels water and features tapered long edges for easy finishing. The front facer mat is tinted grey to match traditional drywall finishing and is engineered to accept the application of USG Boral finishing systems. The back-mat features USG Boral’s distinctive green color.
