USG Corporation announced the completion of its glass-mat portfolio with the addition of four new products.

New exterior product:

  • USG Securock Brand Glass-Mat Sheathing—High-performance sheathing for warranted protection from the elements, with new and improved coated fiberglass facer mat to maximize coverage of air/water barrier systems.

New interior products:

  • USG Sheetrock Brand Glass-Mat Panels Mold Tough AR—High performance interior fiberglass-faced panels, offering greater resistance to surface indentation and impact damage than standard gypsum panels.
  • USG Sheetrock Brand Glass-Mat Panels Mold Tough VHI—An upgrade to abuse-resistant panels, these high performance interior panels offer very high impact resistance and added resistance to surface indentation and impact damage.

New wet area product:

  • USG Durock Brand Glass-Mat Tile Backerboard—For use in wet areas where moisture- and mold-resistance is required, these panels combine cement board-like tile bond with the handling and ease of use of a USG Sheetrock Brand gypsum panel.

“In an effort to provide the industry’s most robust wallboard portfolio with best-in-class service, USG now offers customers a choice for all of their glass-mat needs,” said Greg Salah, Senior Vice President & General Manager, North American Gypsum at USG. “The full-line of high-performance products includes a new coated sheathing, four interior glass-mat panels, a shaftwall liner panel, a new tile backerboard and a roof cover board, all engineered with moisture and mold resistance.”

All USG fiberglass-faced products feature an inorganic water-shedding glass-mat enclosure and a fire-resistant gypsum core that is treated to achieve the highest ASTM measured mold-resistance rating available.

The USG glass-mat portfolio, recognized by the distinctive green color, delivers a complete moisture- and mold-resistant solution under three trusted brand names: USG Sheetrock Brand for interior applications, USG Securock Brand for exterior applications, and USG Durock Brand for tilebacker applications.
