Rated 4.4 out of 5 by 47 reviewers.
Rated 5.0 out of 5.0 by Best Product on The Market for Sound/Fireproofing Roxul Safe'n'sound is made from natural and recycled materials. It is fire resistant due to it's high melting temperature (1177°C). Does not rot, promote mildew, fungus, or bacteria. This is a great product and an easy DIY job that anyone can do. Tools required for the job are a serrated bread knife it works better than a utility knife, measuring tape, long sleeve clothing and a dust mask. Although it is not advertised it does have and R value of 11. Dwight Simpson - Simpson Properties January 29, 2015
Rated 5.0 out of 5.0 by this product does as reported: Muffles sound Just read in a review that it didn't work for someone. I can attest to using this product on countless jobs, it is a winner. I prefer to install it in all walls, if the client will let me. Great sound dampening.... excellent product. In no way does it compare with the old fibreglass batts! January 10, 2015
Rated 5.0 out of 5.0 by It's okay for sound insulation Don't. Expect this product totally isolate sound transmission coz it does not. It tends to filter sound on higher frequency but muffle lower frequency. It is stillbetter than nothing, I have use it on all my interior walls and ceilings. It suppose to work with resilient channel and thicker drywall for best results. But then its more cost for slight gain. Despite Roxul don't published Rvalue, it is of the same material of regular insulation but denser and heavier to give it the better sound and fire protection. It's Rvalue should be R12 base on thickness. Compare to pink or yellow fiberglass, this does not sag or compressed much and retain the shape. The big bonus is it does not promote mold even wet. I have got rid of all the pink insulation when renovating. September 20, 2014
Rated 5.0 out of 5.0 by Good product I had to redo the base of the wll of the shed of an old house that I bought since the baseplate, the bottom of the studs, the floor bolts and the fiberglass insulation had all rotted. So I used pre-treated wood for the new baseplate and the bottoms of the studs that I had to repair/replace. But, for me, an important part was the insulation. I read that this product is waterproof so it won't be affected by any moisture or water seepage that gets into it. So far, so good. If things go the way I'm told they will, I'll be back in a few decades for the update. I trust that it'll have been worth it. April 7, 2012
Rated 5.0 out of 5.0 by I had an energy autit performed on my house. Most of the air leakage was through my basement . I installed Roxul insulation throughout my entire basement and after I had my 2nd audit done, my ratings increased from a 61 to a 68 which is the same as that of a house that was newly built. It was also a lot nicer to install than the fibrelass stuff as it expands out and pushes beteen the studs providing a dense coverage. Needless to say, our house is a lot warmer now. January 8, 2009
Rated 5.0 out of 5.0 by Effective Sound proofing I recently completed a basement renovation and used safe and sound along with resiliant channel to strap the drywall ceiling. My customer was shocked at how quiet their basement is now. I trully hope they never have the oppertunity to the fire suppression! September 7, 2010
Rated 5.0 out of 5.0 by soundproof This product is so easy to use and cuts down on noise dramaticly, the added fire safety is comforting and none of the fibres flying around like fibre glass insulation make it easy to use. My son plays guitar and loves the quiteness of his room now.. January 27, 2009
Rated 5.0 out of 5.0 by Excellent! This product is really good. It reduces noise between rooms and improves the quality of a house! January 14, 2008
