USG has expanded its line of lightweight drywall with Sheetrock Brand UltraLight Panels Mold Tough. The panels have the same mold and moisture resistance as standard green boards but weigh only 1.35 pounds per square foot (compared with 1.65 pounds). They can be used as a tile substrate in areas with limited water exposure. Though currently available in only four states (New York, New Jersey, Pennsylvania, and Delaware), they are being rolled out to the rest of the country over the course of this year. Pricing is the same as for regular Mold Tough, or about $12 to $13 for a 1/2-inch-thick 4×8 sheet.
