USG. Up to 30% lighter than traditional gypsum wallboard panels, Sheetrock UltraLight Panels can help offer easier installation with less fatigue for drywallers. The new panels incorporate colloidal chemistry to yield a higher strength-to-weight ratio and improved sag resistance. Available as 1/2-inch wallboard or ceiling board, the panels come in standard lengths of 8, 10, 12, 14, and 16 feet in length, and 48- or 54-inch widths. Other benefits of the Sheetrock UltraLight Panels are cleaner score-and-snap and the ability to place more product per truck for deliveries. 800.874.4968.
