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.

Owens Corning makes great insulation! It installs easily and doesnt leave much of a mess. I'd recommend it to a friend or anyone doing insulation work.

Basic insulation

Would Recommend

I got this for helping semi-finish some attic space. Fiberglass is a classic standby insulator; use of R38 was overkill but the precut size made it simplest in this case. If working in tight spaces, be aware the product thickness expands by about a factor of 3 to 4 once the outer plastic is removed.

Easy install

Would Recommend

Very easy to install because of it being cut into 4ft sections. Our home is much warmer now. We are hoping to see a decrease in our utility bill.

Basement ceiling insulation

Would Recommend

I installeed OC R-38 faced insulation between the garage and basement ceiling along an HVAC pipe. I noticed the difference immediately. Especially when temperatures plummeted below zero.

Easy installation.

Would Recommend

I installed this product in the attic above a bedroom which did not have any insulation. Noticed a benefit immediately with the ambient temperature increase. Last winter the room was 10 degrees colder than the rest of the house. No longer thank goodness. Actually that room is warmer than the rest of the house, so that will be my next project to increase the insulation there. However, I will have to use the unfaced version since there is already some insulation. Incidently, the pre-cut aspec...

great product as always.

I purchased this r-38 for my garage ceiling and it is a great product especially in Pennsylvania in winter. I could notice a great improvement in heating and a lot less heat loss out the roof. I would definitely recomend.

Very thick and good quality

This is for laying down in the attic, it won’t fit other places or walls if you don’t have room. It is a foot thick. If you lay on existing insulator in the attic, make sure it is placed the opposite way (if old ones are vertical then you place these horizontal) so it seals the air even better.
