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.

Easy 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.

Price

Easy to use and cheaper than the Kraft paper one.

Would Recommend

Easy to use. You can unroll it on the ground and cut it with a box cutter if needed. I used to insulate my attic over my garage. Perfect height to go between the 2x4s without rising above them. This lets you easily lay plywood down if you want a floor. The one with paper on one side would be slightly easier to work with but the price difference made this the better financial choice.
