Sage&Sound goes under your subfloor, in most cases that means you install in from the below storey.

Will this work for generator box interior walls to help with sound absobtion before it escapes?

Answers

Yes, it will certainly help reduce noise. I would suggest that you put something up to hold it in place as it will tend to fall apart over time. Staple some plastic or a screen would do. It doesn’t bother your skin at all, which makes it great to work with.

Can i use this on an exterior wall in a bedroom and still be considered insulation?

Its a 3" thickness and will provide approx. R11...…. COMFORTBATT at 3.5" will be R15 and fully fill the 2 x 4 cavity depth which is recommended. Further questions? email us direct contactus@rockwool.com and we can address them

Is this product R-15?

Asked by George August 5, 2020

Answers

Dear George: Yes. For whatever reason, RockWool doesn't advertise the R-value of the Safe 'n Sound version of their rock wool product -- but it is just as effective for insulation as the standard version. A couple of tips for installation: (1) The fibers are itchy and irritating, like fiberglass. Wear gloves and a good face mask -- NOT the kind with a rubber band in the back. Look for a 3M 07192 respirator online. For large jobs we also wear a cheap tyvek painting suit, so our clothes don't get filled with the fibers. (2) You can hold the batts in place in overhead joist bays with Simpson insulation wire, which Home Depot carries. (3) Safe 'n Sound helps to reduce sound but is not a magical cure-all. If you want to reduce sound in a room, read-up on the Web, e.g. on double walls, double drywall, sealing shared HVAC ducts, etc. I hope this is helpful. Mark

Note that ROCKWOOL products should not be left exposed to the elements. If this water pump box is sealed from exposure to the elements ROCKWOOL may be an option to review. Note we do not have any specific systems testing for this application

Can this be installed to one exterior wall on new construction I heard it dosen't have R rating but either does aircrete.

SAFEnSOUND will provide an R3.9 per inch..... we have a STD letterhead available confirming this testing. Note at 3" (Approx R11) it may not be high enough to meet you code requirement. For further response please email direct contactus@rockwool.com Also note this is used as an interior batt, pressure fit between wood or steel stud framing members in interior partition walls and floor / ceilings

Could I use this in a window area temporarily to reduce or drown out incoming sound from let’s say... fireworks?

Asked by JohnnyBravo June 21, 2020

Answers

Yes, but I would suggest framing the edges with tape. To make mounting & demounting easier. The great thing about this product is that it will not throw off fibers that can irritate skin of people or animals.

I used this in the floor joists between my kids' playroom and my home office. I'm fairly certain it does nothing to absorb the sound because I can hear my kids talking (and worse, stomping) above. This was used in conjunction with resilient channels and 1/2" drywall.

The product will provide sound dampening in this application. Note that sound will travel through any gap in a wall or floor/ceiling system. If you have hardwood floors, the purpose of the RC Channel when correctly installed will decouple the drywall from the wood framing which will assist with the impact sound you advise. rockwool

Customer review from rockwool.com logo
I chose safe and sound to insulate our son’s room that we were building. He gets loud when he games online with his friends and we needed sound proofing that was inexpensive and easy to install. I love the product. Very easy to work with which was great because I’m a novice at home renovation.

This product does not do even close to its 50% rating. You can still hear everything. This is good for far away misc. noises.. but conversations, radio playing, tv, and other loud noises - forget about it.. it goes right through. I must have bought $3000 of this product to do (2) apartments.. in the walls, double layered in the floor and ceilings.. it did minimal sound protection from the neighbors next door. It’s a way overpriced product for about 30% of what it claims to do. If you want to soundproof a wall.. stagger the wood party studs, add resilient channels with a rubber backing, use quietrock 530 series ( yes.. the expensive one) laminate it with 5/8” Sheetrock with greenglue compound in between. This is a severely overpriced product!!

Works GREAT, totally keeps sound out, of course if you knock on the wall you're going to hear that. I used it in the bathroom to keep embarrassing "bathroom" sounds from escaping thru to a common area. It's easier to install than fiberglass because its stiffer and easier to cut and shape by using just a bread knife or maybe even a serrated steak knife. It is a lot more itchy than fiberglass so use long a sleeve shirt, gloves and also a mask as there are rock particles that come off of it while installing and cutting. I don't like how its described on the website, it should say that there are 12 bats of 3"x15 1/4 x 47" or a total of 564" or 47 feet of length. It seems really expensive when you just say that its 3x15 1/4 x 47" for around $50 (seems like its for only one piece) which almost deterred my from purchasing it.

Great Purchase and Easy Install!
Customer review from rockwool.com logo
Wow! I purchased 30 bags of the ROCKWOOL Safe 'n' Sound and was able to install it all by myself. I calculated that many bags on Rockwool's bag calculator on their website! Very accurate.. This product was very easy to install. Cutting around outlets, wires, and pipes was like cutting bread. Before the drywall went up, I could already tell a difference. I put the Safe 'n' Sound around all my laundry room, bathrooms, bedrooms, and in the basement ceiling. Not only does it provide sound proofing, it has other benefits as well. Such as fire resistant and no mildew can grow on it. I am so glad my builder let me install this product on my own. Would I recommend this product? Yes, 100%.

Exactly the product we wanted and needed!
Customer review from rockwool.com logo
We are renovating a 110-year-old stone carriage house. Rockwool has been our salvation for many reasons: exceptional thermal efficiency, super sound blocking, and mice hate it! Easy to install. We wrapped our new enameled steel tub with Rockwool for added insulation; my love of hot baths appreciates the extra 30 minutes I can spend reading in my tub before bed! And best of all, it has a low carbon footprint. Everything to gain when we opted for Rockwool instead of the irritating pink fluff.

Having to build the wall and adding the roxul plus, sheetrock wasn't worth the cost, labor or the slight reduction in sound. I never knew people could use so many cuss words at their children. Really disturbing!

Works amazing for muffling sounds. With big loud dogs now there's no vibration and it blocks pretty much every possible sound. Because it is a remodel, the rockwall is sitting on top of the ceiling of the basement, instead of staying in between the joists, but it works just as well. Wish I used it on all walls I ever worked on. Would highly recommend it around bathrooms or in between bedrooms.
