Customer review summary generated by AI, including incentivized reviews.Good product
The 2’ x 4’ batts are really easy to place and work with as opposed to rolled insulation. One thing that surprised me was how heavy a 10 batt package was. Not fun getting it into my attic.

Paying more and getting less
I could get two r- 15 for cheaper but two years ago I bought and the thickness was far greater. No I am paying more but getting ripped off on thickness. If you have a choice by another brand. There are other outer there but may have to drive to get cheaper and better if doing a major remodel..
