Final answer:
The correct answer is option B; 1/4" drywall is used for curved walls due to its flexibility, which allows it to conform to irregular shapes and create special architectural features.
Step-by-step explanation:
The correct answer is option B. 1/4" drywall is typically used for curved walls. This type of drywall is thinner and more flexible than other types, which makes it suitable for creating walls or surfaces with a curve. Due to its flexibility, contractors and DIY enthusiasts often use 1/4" drywall when they need to conform to irregular shapes or when constructing special architectural features that require a smooth, curved surface without the need for scoring or creating multiple relief cuts. It's not typically used for joint treatment or stress joints, which often require a different approach and material specifications to ensure proper strength and durability.
When it comes to joint treatment, 1/4" drywall is ideal for taping and mudding the seams between the drywall panels, creating a smooth finish. It is also commonly used for curved walls because it can be easily bent to fit the desired shape without breaking.
