Customer review summary generated by AI, including incentivized reviews.Easy to use and cheaper than the Kraft paper one.
Would RecommendEasy 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.

Solid insulation
Would RecommendGreat installation for any general project that you are working on. The only issue was this package was slightly ripped however I think that was an individual item issue not a product issue.
