Yes, there is a difference. Ceiling drywall is usually thicker (5/8 inch) than regular drywall (1/2 inch) to prevent sagging. It also has a higher strength-to-weight ratio which is critical for horizontal surfaces and to meet fire-code requirements. Always use ceiling-specific drywall for overhead applications.
