Final answer:
1/4" and 3/8" sheetrock are not recommended for curved walls. Thicker sheetrock is commonly used for sound control, while both thicknesses are suitable for joint compound.
Step-by-step explanation:
1/4" and 3/8" sheetrock are NOT recommended for curved walls. These thinner types of sheetrock are more difficult to bend and may crack or break when attempting to install them on curved surfaces. Thicker sheetrock is typically used for curved walls to ensure a smoother installation.
On the other hand, 1/2" or 5/8" sheetrock is commonly recommended for sound control because of its increased mass, which helps in reducing noise transmission. Thinner sheetrock may not provide the same level of sound reduction.
Both 1/4" and 3/8" sheetrock are suitable for use with joint compound. The compound will help to create a smooth and seamless finish, regardless of the thickness of the sheetrock used. However, thicker sheetrock may be preferable for certain applications to provide more durability and resistance to damage.
Resilient channels are designed to improve sound control by effectively isolating the sheetrock from the studs or joists. While thinner sheetrock can be installed with resilient channels, it may not provide optimal sound reduction compared to thicker sheetrock.
