Ratings & Reviews for ROCKWOOL Comfortbatt R- 30.0 Attic Wall Unfaced Stone wool Batt Insulation 30-sq ft ( 23.0-in W x 47.0-in L )

I WOULD BUT THIS PRODUCE AGAIN

Used in a new pump house. worked great and easy to use. Has not froze since.

Easy to use

Much easier to work with than fiberglass. Sound reduction is a plus.

Great Product

Rockwool Comfortbatt is easy to install & retains it shape overtime. This product is more great for homeowner who live in a humid areas like Houston Texas since Rockwool Comfortbatt is resistant to mold & mildew which limits bacterial growth in your walls.

Really works, much better than fiberglass.

See pictures attached, installed them on the room next to the entry door stairs which used to be the coldest, now it is warmest. Obvious warmer feeling in the next day morning. Really works, much better than fiberglass.

Good stuff 4 stars because product is a little crumbling.Workable but easily distorted or broken.

Great product.

This is a great product. Living in Florida I especially like the fact that it does not rot or promote growth of of fungi or mildew and it is moisture and water resistant.

Good product

4 stars for me. Wish the bails were bigger and held more.

The amount of sound reduction is immediately noticed

So far, I have bought 5 packages of the comfortbatt to finish my garage and I don't have plans to stop there. I am insulating and finishing our 2 car garage and when just one wall was insulated the noise reduction was already very noticeable! It is easy to cut, easy to install, easy to notice a positive difference! I am already planning on using the safe'n'sound on my next project. The only complaint I have is that for as heavy as the packages are the bags tear too easily trying to load and unlo...

This should make regular fiberglass insulation obsolete

I'm remodeling my 1950 mid century modern home one room at a time. I started with the hardest room to heat & cool, knocked out the old plaster & had the room sprayed with rigid & soft foam. The guys rushed the job & left some thin spots and even bare wood showing thru. I wanted to fill voids with Roxul but could not find it anywhere in Oklahoma so I hung the drywall anyway. Since then I've found a dealer 30 miles from me that can order it. I've since used Roxul in my sun room & garage. I l...

Prefer rock wool insulation

Having finally found a vendor in the local area that would sell it, I use nothing else. It doesn't mold. Air and moisture do not as readily move thru material as such do fiberglass. Bugs don't appear to like the stuff. R value per inch provides better insulation in remodel of structures with 2x4 walls without resorting to scabbing 2x2s or double-walling exterior walls.

Comfortbatt's fire performance gives you piece of mind

I used it for wall insulation.

Absolutely will buy again.

I am in the middle of a full renovation and have used Roxsul in my attic. I plan on finishing walls with Roxsul also. Very happy overall with product.

Works great in our 1942 house!

We had the old insulation vacuumed out of our attic, to get the house re-wired. There's still some to do, so some of the attic is uninsulated at this time. This has actually been interesting, despite the high temps where we live, because we can measure the effects of different amounts of insulation. The first layer is the R15, to the top of the joists. The entire attic will have this. For some areas, this is ALL that will be there, because my husband wants to be able to access some areas, s...

I'll be buying more of this

I remodeled a room and insulate with R15, it was great to install and send to work well

LOVE IT !!!!!

I had used quite a bit of the Comfort Batt when we lived in VT ( mainly our last house we had up there) and loved it , our house stayed nice and warm plus i put some in a wall that was between out living room and office ( there was a tv and sound bar hanging on that wall) and when I was in the office I could barely hear a thing . Our current house is now in PA and I want to put some in but do not have the funds , it is a very large and prominent victorian house that has been neglected so money ...

Great Product

I used this product in my basement below grade. Works great. I am now going to use it in my lake home remodel. Thank You

Easy to work with!

Used this in our basement to fill gaps between floor joists (that little picked between the concrete basement wall and the ceiling) - flexible, easy!
