What specific item is categorized under the drywall section?

The choice of 1/2" drywall is correct because it is the standard thickness commonly used for residential interior wall applications. It strikes a balance between weight, ease of handling, and structural adequacy, making it the preferred option for most walls and ceilings in homes.

In contrast, while 5/8" drywall is also utilized, particularly in commercial applications and for fire rated assemblies, it is not as broadly categorized under standard drywall types for residential use. The 3/4" thickness is atypical and not standard for drywall; it’s rarely, if ever, used, while screws, while essential for installation, do not fall under the category of drywall itself, as they are a fastening accessory rather than a type of drywall.
