Questions & Answers

most are using for sound but I need for fire , is this product good for a 2 hours fire stop ?

need to cover 9 holes 12" × 24" do I need to double up to get 2hr fire stop ?
Asked by: Marco
My wife did not believe that this product would not burn, so I started a large fire in our 6 foot round fire pit then took a 12 in by 12 in piece of safe and sound and threw it in with the hot coals and fire. When we came out the next day the only thing left were the wood ashes and 12 inch by 12 inch piece of safe and sound. When I picked it up out of the pit it was still warm and the side that touched the hot coals was singed and black with very little damage to the piece. She was impressed and so was I, slowly putting it in all my interior walls.

ROXUL Product Expert, he just wants to know if 12 of the 47" batts weigh 37.8 pounds. Of course, the answer is "yes."

Can this be used with 2x6 framing?

I don't see an option for x6 framing. I'm planning on using this to help sound proof an internal wall/room in a basement that is framed with 2x6. Will this be sufficient?
Asked by: patgmac
Yes. You can use it for interior walls of 2x6 thickness. You actually want a 1" air barrier between the room that will create the sound and the room that you're trying to stop the sound from going into. If both rooms will be sources of sound, then you can put the Roxul in the middle, if possible. Remember there are, at least, 3 things you should do to minimize sound: 1) use acoustic caulk around outlets and any holes in the walls. 2) Use Roxul. 3) use steel resilient channel and hang your drywall on that. You can also use QuietRock or thick drywall or 2 panels of drywall glued. I'm not a Roxul rep. But my son plays the bass on the 1st floor and we've been able to decrease the sound to some degree by placing it below the subfloor. We still need to do more to decrease it further. I haven't had the chance/money to use the resilient channel and I'll need to do that to decrease the vibration from the 4x10" speakers amplifying his bass guitar. I'll also need to put it on the interior walls surrounding the room as well. Best of luck to you. :-)

Can you staple this or is it too thick/hard?

Can you staple this or is it too thick/hard?
Asked by: calva
You can staple through this. It's 3" thick and you can compress it. But if you compress it so that you can staple it, you won't get the sound proofing qualities it offers. If you're wondering if it will remain up on its own between 2 joists that are 16" on center the answer is yes. I have batts of it sitting between 2 joists in the basement ceiling. They have been there for 8 months and they are holding their position. Nothing is falling down. I hope this helps.

Safe 'n' Sound 3 in. x 15-1/4 in. x 47 in. Soundproofing Stone Wool Insulation (1-Bag) is rated 4.5 out of 5 by 148.

I have a master suite (with a private entrance) that I rent out thru Airbnb. Although there is a wall between the suite and the main house, the noise back-and-forth between the suite and the main house was very audible with standard insulation and I could hear parts of conversations and the t.v. My handyman removed the standard insulation inside the wall and installed the Roxul. The product was easy to work with and installation was a breeze. OMG - this resulted in true soundproofing - I can't hear voices, and even when the music and or tv are blasted so loud in the suite to hurt my ears, it's silent on my side. Amazing stuff!

The good batch (stamp looked like "MN") was dense, firm, and uniform in thickness. The bad batch (stamped w/ Roxul "heart" logo) was flimsy, lumpy, and easily tore apart.

The sound dampening for voice, music, etc between walls is pretty amazing. It doesn't completely cancel it out but it's really nice. I have then just put in the basement ceiling joists and all around my workshop in the basement. Again the noise transmission is severely reduced. Now if you want to really cancel out the foot step noise you'll want to add a resilient channel in unison with the roxul. That would greatly cut it down further. I have found that the feet noise still comes through but the voices, tv, music is all greatly reduced. I would use it again for sure. Super simple to work with.

It was apparent after the first bag that this stuff really dampens the sound. I've done two rooms and even with bare stud walls you can really tell the difference when you step in them. This stuff can be a bit difficult to install when HVAC ducting is present between the joists as it isn't as flexible as fiberglass but it is still well worth it.

I purchased four packages of Roxul Safe 'n' Sound 3 in. x 15-1/4 in. x 47 in. to treat my home recording studio which consisted of a drumset recording room and a production room (corner super chunk bass traps and sound baffles for walls and ceilings) and the product worked great. It was easy to cut and stack, minus the fact it "flaked" off in small chunks and when stacking them in triangle sections they tended to buckle in the middle and fall over. I've had them up for about 4 weeks now and have received many compliments on how well it dampened the sound in these rooms.

If you're looking to sound proof a room, or create your own DIY acoustic treatments, this is the insulation you are looking for. Compared to other products, this is by far the most reasonably priced. But don't let the price fool you, it does a great job at capture sound frequencies. Overall very happy with this product, and would recommend it to anyone looking to sound proof or treat an existing room.
