Ratings & Reviews for ROCKWOOL Comfortbatt R- 23.0 Attic Wall Unfaced Stone wool Batt Insulation 39.8-sq ft ( 15.25-in W x 47.0-in L)

Basement rim joist insulation

Worked on removing and replacing the orig. fiberglass batt insulation in the basement. I chose the Rockwool Comfortbatt R15 batt since it appear to be a better product than replacing with new fiberglass batts. I think the Rockwool product was sightly more expansive, but I found it easy to work with. We'll see how good are the energy savings over time.

Rockwool rocks!

First time using Rockwool in our renovated home. As soon as we put it in the house was quieter and instantly warmer. We are now at the drywall stage and are only using two small electric portable heaters and the house is T-shirt warm! I can imagine how warm it will be once we turn the furnace on and how much money we will save in heating bills! The Rockwool Comfortbatt product is so easy to use and went up so quickly. We had one whole floor done in two days with just two of us doing the work. Wi...

Good price for quality

Good insulation and for a good price for the job, recommended for pole barn by contractor

Great Material

Five star material here. Easy to cut and install, just select a good vapor barrier I chose Intello Membrane and done. I do like benefit of this material not being able to burn. And if it get wet it will dry out and will still do the job it was intended to do. And no itchy arms while installing it, perfect !

Easy to customize

Said goodbye to pink crap insulation and hello to lovely rockwool. Had major problems with squirrels in old log cabin unfinished basement ceiling. Once we cleared out the old insulation (riddled with poop and nests), we crossed our fingers that this new insulation would be inhospitable. The week after installation, they messed with one small section, which we pushed back into place with a garden hoe. I had to repeat this a few days later, but the insulation wasn’t destroyed just pushed out of pl...

Inspector was very impressed

DIY installed comfort batt in my 2 story 1200sq foot guest house workshop on top of 2 inch closed cell spray foam Extremely easy to work with. Love the tidy appearance and so did the inspector.

Comfortbatt for interior foundation walls

I've started to install Rockwool Comfortbatt insulation for my basement renovation, specifically for the interior foundation walls and rim joists. Using Rockwool, in combination with 2" rigid insulation meets the local building code requirements and has greatly improved the temperatures in my home, creating a much more consistent room temperature. The installation process was very simple, and I'd highly recommend this product over the competition.

Garage loft

Using rockwool in garage loft. Great product to use.

Best Product on the market

Rockwool Roxul insulation is the only product I will use. Roxul is so easy to install and works so well. Since this product came to market I have been so happy. In my opinion fiberglass insulation is so inferior to this product, for ease of installation, fire rating, moisture resistance, and does not compress over time. Roxul works so well that when I perform any insulation upgrades I know that I never have to worry about its performance in the future. This is definitely the only product I will ...

Best insulation, but pricey

Used in our basement walls. It's a bit pricer than fiberglass insulation batts but I wanted some anti rodent insulation for our basement as the previous owner had a mouse problem down there.
