5/8 drywall
Appearance
5/8-inch Drywall
is a thicker, denser gypsum board, often labeled as Type X, known for superior fire resistance (offering a 1-hour barrier), better sound dampening, increased durability, and greater rigidity, making it ideal for ceilings with 24-inch joist spacing, garage walls, home theaters, and commercial projects, though it's heavier and more costly than standard 1/2-inch drywall.
