Today USG announced nationwide availability of the first and lightest Type X wallboard in the industry, USG Sheetrock® Brand UltraLight Panels Firecode® X. This panel is available in one of two Underwriters Laboratories Inc. (UL) Type Designations (Type ULIX and Type ULX), depending on geography.

These panels are the industry’s first lightweight Type X gypsum panel designed for commercial and residential construction. Both UL Type Designations of USG Sheetrock® Brand UltraLight Panels Firecode® X have been formulated to achieve all the strength and performance characteristics as standard 5/8″ USG Sheetrock® Brand Firecode® Gypsum Panels at a significantly reduced weight. For contractors and gypsum specialty dealers, lighter weight means transportation efficiencies, productivity gains, reduced fatigue during handling and possible safety benefits.

“USG is the industry leader in gypsum panel technology and is the only manufacturer to offer a full portfolio of lightweight products,” said Dan Schmidt, Director, Product Management -Wallboard at USG. “The new UL Type ULIX panel was developed utilizing a proprietary formulation. The primary difference between the ULIX and ULX panels is that the ULIX board requires the use of insulation in the cavity on one-hour fire-rated steel-framed assemblies, which is an industry best practice designed to meet thermal and acoustical performance requirements,” adds Schmidt.

UL Type ULIX panels are available in the following regions:

  • West North Central
  • Mountain
  • Pacific

UL Type ULX panels are available in the following regions:

  • New England
  • Mid-Atlantic
  • South Atlantic
  • East Central
