What Customers Are Saying

Customers overwhelmingly praise this insulation for straightforward installation, exceptional thermal performance, and superior quality. Most highlight immediate temperature improvements, minimal dust, and reliable R-value delivery in attics and walls. The pre-cut dimensions and uniform sizing enable quick, tool-free installation. Reviewers consistently report noticeable comfort gains, with many noting heat retention in winter and blocking in summer. The thick batt construction and reduced dust compared to older types earn frequent praise. A few mention minor issues like inconsistent kraft paper flanges or occasional compression, though most consider the quality well worth any drawbacks.

R-38 Insulation

I used this stuff for my attic crawl space in my attic. I had old rock wool in the ceiling and it was in terrible shape. This stuff was easy to work with in the 4’ sections. M

The product was easy to install with the 4’ pre-cut bats of insulation. R-38 in the attic will keep the house comfortable all year round.

Great for the attic

 Would Recommend

Had a little roof leak that resulted in a 3 foot section of damaged insulation. Found this and used it to replace damaged piece. Wish I could have bought a single piece with this R value but that isn’t available at Lowe’s. But this was easy to cut and put in. Now I have plenty of extra to fill in spots where I may be lacking in insulation
