The agency likewise states that the product is "stronger pound-for-pound than standard 1/2-inch drywall." It may, yet, be weaker on a square foot basis, which is the anecdotal evidence from installers and also building contractors. Professionals report that ultralight panels might be even more brittle and more at risk to edge breakage than typical drywall panels. But Datasheets for the product state that, for hardness and flexural stamina, Sheetrock UltraLight "meets or exceeds" ASTM C-1396 Specifications. For DIYers, tbelow is really no factor to prevent ultralight drywall out of pertains to for its strength.
