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.

Great insulation

Would Recommend

Bought this insulation to insulate two rooms of my home that were previously converted from a garage, and to replace old nasty insulation in the rest of the house. We went with this batt insulation instead of spray-in insulation because we felt if we ever had to get to any of the wiring or fixtures, it would be easier to lift strips of this up than have to cut into dried spray insulation. This was very easy to install, and really fluffs up after you cut the packaging open. Fiberglass didn’t get ...

Beware of Lowe’s Delivery

Would Not Recommend

I had ordered 20 of these R-38s. The delivery guy delivered only 12. It’s been 5 days since filing a complaint with Lowe’s. My money is still stuck with Lowe’s. Unfortunately, Lowe’s do not want to reply to my calls or complaints. Every time I call Lowe’s 1-800 number, they say “we have contacted the local store ant Hicksville NY and the local store will call you back.” Seems like the 1-800 support guys are just pass-by. They have no accountability/responsibility. Highly disappointed wit...
