Product info says the R value is zero. Is there an equivalent r-value? What does this actually insulate with zero R value?
Asked by: yourbrokenoven
Fiberglass offers an R-value of 2.2 to 2.7 per inch, while rock wool has an R-value of 3.0 to 3.3 per inch, making it a slightly better insulator than fiberglass, according to the U.S. Department of Energy.Dec 14, 2018

How many bags needed to do 700 square feet

Asked by: JC
Each bag contains 10 batts. Each batt covers 4’ x 16”. That’s enough material to go in between five 16” wall spaces if you have regular 8’ ceilings. That equals about 6.5 linear feet of wall, or about 52 square feet of wall per bag.

Wow ,, very impressive insulation/sound killer,,, Its like a sponge for sound, Soaks in all the noise then keeps it there,, I insulated 3 rooms in my basement, The boiler room, a future home theater and a future 1/2 bath... I love it for the boiler room as it provides protection from fire, and since I put it in, I can no longer hear the boiler running from the upstairs living room which is right over it,,, It Fits snugly in between the beams and there is no need for wires to hold it in place. You can see in the pics below I have it installed in the 2 x 3 walls and in the 2 x 10 ceiling joists as well, I ended up doubling it in the ceiling because I had enough and wanted to cut any noise from the home theater. With all the insulation in not only is the room warmer, but the sound deadening qualities are amazing,,, I can yell from the theater room and my wife cant hear me from the other side of the basement.. I am very impressed with the fire safe qualities, you can see in my video below I torch it really good and it barely smolders and seems to self extinguish making me feel very safe as the basement is the last place I want to be trapped in a fire.. It insulates, Makes it quiet and keeps you safe, a great product at a great price and its hardly itchy... Cuts easily with a corrugated knife and installs easily

I expected rock wool to not be itchy but this is, not nearly as bad as fiberglass though. I recommend a dust mask in the area of cutting and installation. I cut it with an old electric knife, very easy. Construction was targeted at STC-50, looks like I will easily get STC-70. Project used 4 pallets of this product.

Time to get the basement ceiling joists insulated to keep everyone comfortable on the main and 2nd floors. I requested this insulation to install a second layer of insulation between the basement ceiling joists. I had already installed fiberglass insulation (acquired through the Home Depot Seeds reviewer program just like for this product), but the dogs still seemed to wake up our child with her playpen in the first floor livingroom and the dogs directly below her. This insulation you can tell just by lifting a bag of it is much denser than fiberglass insulation, and when you open the bag, you'll notice that this mineral wool insulation is more like the consistency of a dense cake. Installing it is actually pretty easy as long as the individual batts are trimmed to fit the spot they are going into (cut out spots for electrical boxes or any other large obstructions). All you do is lift the batt, angle one long side in final position to the joist/stud and then compress other long side of batt up into the joist/stud bay. No need for anything to hold it up since this stuff won't compress a whole lot. If you do need to cut it to be more narrow, give it no more than 1/4" for friction fitting. Any more than that and you'll never be able to get it in the space.

If you have a project that requires insulation, mineral wool insulation is what you need. FORGET fiberglass and go with Thermafiber. Mineral wool has a better R-value and is vastly easier to install than typical, comparable fiberglass batts. I used the Thermafiber 3"x15"x47" Fire and Sound Guard batts to insulate my basement before finishing. I've installed faced and unfaced fiberglass batts, and I'm sold on the superiority of mineral wool. All you need to do is cut to size, then squeeze into place - no more stapling faced batts to studs. Mineral wool also retains its shape, so it's much easier to handle and fit around pipes, wiring, etcetera. Mineral wool is also less itchy than fiberglass, so win-win-win here.

As others have said, this product is not as easy to work with as the ROXUL product Home Depot used to carry, but it is half the price of the ROXUL product sold by the other store, there isn't a 3 bag minimum, and its in stock. The bag I purchased didn't have any smell. If you just need to fill in the space between studs this product is excellent. If you need to make 90 or 180 degree bends without it falling apart the ROXUL product may be worth getting. Considering price and availability, I'm happy with the Owens product and will buy it again for most of my sound and fire insulation projects.

Some of it was too easy to tear, fell apart easily in our hands, and felt like it wasn't compressed properly. Overall it was worth it because it works well to dampen sound.

Have used another brand sold by Home Depot a few years ago--same good quality with slightly different attributes--and now am working on re-insulating another room. This brand has a product for the inside of your external walls that is slightly stiffer and another for sound reduction between interior walls between rooms. Both work just fine, are super easy to install, stay in place, keep out the cold and--the clincher for me--are fire resistant.

Rated 5 out of 5 by from Insullation keeps bathroom private I Had a contractor install about 150 ft.² of the sound insulation in a bathroom when bathroom was being remodeled. It does a great job of stopping all of the unpleasant noises from getting out into the rest of the house when somebody is in the bathroom. The only thing you can really hear is the toilet flush. We have a Bluetooth speaker in the bathroom and you can barely hear the music outside in the house while the music is playing. I would definitely buy this product again.

I was skeptical because it does not have a paper face to staple to the studs and ceiling joists, but it holds in place fine without stapling. I am surprised it does not show an R rating for insulation, but I wanted it more for sound deadening and fire protection, so I didn't care. It looks to be dense and probably has an R rating of 13 or better.

Density was higher than the other brand making it easier to install with less tearing of the fiber. Excellent sound attenuation. Cuts easily without tearing and easy to notch out for obstructions such as electrical boxes or misc. framing. Be prepare to sharpen your insulation knife after every cut or so as the fibers and embedded slag is very abrasive. Also no need to worry about the itching you get with fiberglass but be sure to wear a good dust mask.

Does rip easily, like if you pick it up by an edge, but this is an observation and not a complaint. It did irritate my skin a bit which was surprising, since fiberglass doesn’t bother me. The sound-deadening effect was very good.
