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.

Doesn't Expand to Fill 2x6 Wall
Would Not RecommendThe packaging claims it expands into a 5 1/2" space. It doesn't. It expands at most to 4". It literally does not expand any thicker than the R15 2x4 insulation I put in another wall. The packages I haven't opened are being returned because if I go to the pink stuff, it actually expands into a 2x6" wall space and holds itself in.

Does exactly what it's supposed to.
Would RecommendEasy to use and did the job. Unwrap it, letit loft for about an hour or so, tack it in, throw some drywall up. Great product to helped insulate between two bedrooms. More for sound than anything.

Not 13 pieces - only 9
I purchased 4 units of the R-13 unfaced batt yesterday. The packaging and the description both say 13 pieces per sell unit. There are only 9 pieces in each. False advertising or a typo? The cost is $6.05/piece instead of $4.19/piece. Can I get a refund? Also, this product should be pulled or relabeled. I also bought 4 units of the R21 unfaced batt yesterday. Those state 8 pieces per unit and they do have 8 pieces.
