Practical answers specific to this soundproofing topic.
A 10–15% planning allowance is a practical starting point for many projects. Complex layouts, many penetrations, or unusual shapes may require more.
Not always. Balance square-foot value with handling, access, and seam layout. A smaller roll can be easier to position even if it creates an additional seam.
Measure the surface you actually intend to cover. Subtract large openings only when you are certain they will not require MLV or related treatment.
Choose based on the application, desired mass, handling constraints, and what the complete assembly can support. 1 LB is common for general applications; 2 LB adds more mass per square foot.
