What Customers Are Saying
Customers overwhelmingly praise the insulation for effective thermal performance, ease of installation, and strong value. The batts fit snugly between standard wall studs without sagging, come precut to common lengths, and stay secure with staples. Many report it maintains stable indoor temperatures, keeps pipes warm in cold weather, and reduces energy costs. Reviewers appreciate the lightweight material, minimal compression, and reduced floating debris compared to older products. Most find it intuitive for DIY projects and beginner-friendly. A few mention skin irritation managed with gloves, and minor packaging concerns, but these are framed as minor inconveniences rather than flaws.

Does the individual package contain 11 pieces of 16"x48" insulation, or 5? The title and specifications are different from the picture.
