For acoustic panels please review our video https://www.youtube.com/watch?v=wa5l5LRwl3w and note its typically Comfortboard 80 used which is a 2 x 4 dimension... though you could use the batt product in 24" dimension as an option. Batts are available for either 16" or 24" oc dimensions

Asked by dr January 15, 2021

Answers

Dear DR: NO -- particularly for a gym. Rockwool fibers are itchy and irritating, and definitely not something you want to inhale. We always wear professional dust masks when we install it, plus gloves and a Tyvek 'painter's suit' for larger jobs. You don't need to cover it with much, e.g. 1/2" drywall. Also note, however, that sound reduction is difficult and more than 'Safe 'n Sound' is required. For example, are any HVAC ducts shared with the rooms above? Air flow = sound flow. You could also significantly reduce sound by doubling-up the drywall on the ceiling. Install the first layer and seal all of the joints and perimeter carefully. Then install a second layer of drywall. Cover each new sheet with 2 full tubes of DAP 230 sealant. Then fasten the new sheet with a few long screws into the joists, pressed against the first layer. Again, seal all of the joints and perimeter to block air / sound leaks. Make sure the second layer panels do not contact the walls, and fill the gap between the wall and ceiling with DAP 230. Let the DAP 230 cure for 48 hours, then remove the screws. This will create a rubbery / resilient layer between the two layers of drywall ceiling, which will reduce sound transmission. I hope this is helpful. Mark

You can add ROCKWOOL as an option if you have the cavity depth space to accommodate the thickness of the ROCKWOOL batt. If adding place the ROCKWOOL batt below as its denser oversized material and has a pressure fit. This will support the lighter material above

What is the R value on this product?

Asked by Philly November 22, 2020
3
Answers

Hi Philly, Safe 'n' Sound is specifically designed for interior acoustic applications (interior walls, partition/party walls, ceiling and floor) but will still give you a R-value ranging approximately from 3.8 to 4 per inch. However, we do not recommend using Safe 'n' Sound in exterior wall applications. For optimal thermal performance in your exterior walls, we recommend our R-rated Comfortbatt products. Please contact our Technical Support Team for more details. ROCKWOOL Technical Support Team contactus@rockwool.com 877-823-9790

I installed 20 bags in complete remodel in Florida. The product we easy to cut, install and shape as needed. Since this is my "forever" home (right now) I soundproofed every wall in a 3000 sq. ft. single story home. I also foamed the roof so I need to be careful to only use the product in a couple of bedrooms to insure proper conditioned attic space. Then applied 5/8" fire proof drywall throughout the house. Let me say - you don't hear a thing from one room to the next.

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.

Response from Rockwool TeamJun 20, 2019
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

Easy to work with
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!
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!
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.
