What Customers Are Saying
Customers overwhelmingly praise the insulation for effective thermal performance, ease of installation, and strong value. The pre-cut batts fit standard 16" and 24" on-center framing precisely, install quickly without sagging, and trim easily with a utility knife. Reviewers note significant improvements in temperature regulation and reduced energy usage, with many appreciating its ability to prevent pipe freezing. The material is described as durable, heavy, and well-made, offering comparable performance to higher-priced alternatives at a lower cost. A few mention minor skin irritation and packaging concerns, but these rare issues do not diminish overall satisfaction.

Would RecommendI used this to insulate a roof with 2x10 joists. Once out of the package and manually "fluffed", the batts were 10" or thicker, completely filling the space. They trimmed easily using a utility knife and staples held the face paper well.

Insulation
Would RecommendThis product was just what I needed for a small project in my attic. I like how this insulation is soft and doesn’t float everywhere like some of them do. The price point was also good. I would recommend this product.

Good, but could be better designed.
Would RecommendNot likes: It compresses to easily and the dividers are not easy to identify making the tear offs (i.e., the layers) uneven and not evenly distributing the R30 values.
