USG Corp.’s Sheetrock Ultralight panels are available at Home Depot stores nationwide, according to blog site JetsonGreen.com. The product, first tested in 2010, weighs anywhere from 15 to 24 lbs. less than typical gypsum board, depending on the size. It can be used with a 40% lighter joint compound released in January 2012.
The product has at least 16 reviews at Home Depot, and many of the comments reflect that the panels feel light and score easily, according to the report.
