US: Underwriters Laboratories (UL) has completed fire performance evaluation on some of USG’s Sheetrock Brand EcoSmart Panel products. The testing concluded that 15.9mm USG Sheetrock Brand EcoSmart Panels Firecode X (UL Type ULIX) and USG Sheetrock Brand EcoSmart Panels Mold Tough Firecode X (UL Type ULIX) is specified in more than 260 fire-rated wall, column, and floor- and roof-ceiling UL designs in which Type X or Type C panels are required.
“Quickly and accurately identifying gypsum panel types in the field – especially after the panels have been hung and the joints are finished – can be challenging. Consequently, fire performance may be compromised if Type X panels are inadvertently hung as the ceiling membrane, whether in steel or wood construction, when Type C panels are required,” said Nestor Sanchez, senior manager, building science at USG.
