It won't mute footsteps or any impact noise. I have no personal experience with adding an extra layer of drywall to a ceiling with Green Glue (only to walls), so I don't know how effective it is. I've seen reviews on the internet from people who say it's less effective on ceilings than on floors, and they advocate a drop ceiling with additional drywall, which is fairly effective.attitunehttps://www.blogger.com/profile/09597645225969164299noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-64053557802254765372018-02-12T16:45:29.841-08:002018-02-12T16:45:29.841-08:00You could do it, but I can't cite the differen...You could do it, but I can't cite the difference (in STC) between insulated double-drywall and uninsulated double drywall with Green Glue. This chart from <a href="http://www.soundproofingcompany.com/soundproofing101/understanding-stc/" rel="nofollow">Super Soundproofing Company</a> outlines the STC difference between similar options. <br /><br />My feeling is this: if you have the opportunity to insulated when there's only a single layer of drywall on the studs, do it then. If you add the QuietRock and then wish you had filled those hollow cavities, you'll end up having to put holes through your beautiful new walls. <br /><br />You could approach this in a couple of ways. <br /><br />1) Rent some equipment from Home Depot (or hire a company to do it), cut round holes into the original layer of drywall between each stud, and blow cellulose fibers into the wall cavities. Cellulose will give you more value -- avoid blowing in fiberglass. Then cover the holes with the circular cutouts and mud over them. If they're not cosmetically perfect, it won't matter -- you're about to cover them with a second layer of drywall.<br /><br />2) If you don't have access to a blower or to a company that can do it for you, you could cut out horizontal strips of drywall and push insulation batting (like Roxul) through the openings between each stud, then recover the drywall cutouts. I did this in a smaller area -- it's more of a hassle, but it provided some insulation without having to do a whole demolition. And, of course, you're about to cover this area up with a second layer of drywall.<br /><br />I'm less sure that simply adding QuietRock and Green Glue to the existing layer of drywall on the ceiling will effectively reduce impact noise or TV/music/conversation between floors without doing anything else. It's a bigger cavity and also floors create a lot of impact noise.attitunehttps://www.blogger.com/profile/09597645225969164299noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-87851304870979745792018-02-12T11:52:47.572-08:002018-02-12T11:52:47.572-08:00Great post.

Here's a question: In sound-insulating an existing floor/ceiling, should I (1) blow in cellulose, or (2) add Green glue and an additional layer of sheet rock? Or do I need to do both?<br /><br />This is a simple construction, recently renovated, with drywall ceilings below wood joists, then plywood and wood floors on top of that. No insulation. Right now conversations/TV at normal volume and footsteps are coming through. <br /><br />I don't need perfect soundproofing but need a bit more sound protection than we've got currently. Thanks for any help you can offer.<br />mahnamahnahttps://www.blogger.com/profile/03186701510026759777noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-13548300361108196582017-11-30T07:56:14.569-08:002017-11-30T07:56:14.569-08:00Very happy.

Afterwards, I added the QuietRock on top of the original drywall (with Green Glue). On other walls, I did a demo and replaced the original walls with QuietRock. In those cases, I used fiberglass batts. I did the demo a few years ago. If I was to do it again now, I would use Roxul Safe 'n' Sound, a product that wasn't as easy to find a few years ago. I think it's denser, more effective, and more fire-resistant.attitunehttps://www.blogger.com/profile/09597645225969164299noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-74086248694399369162016-12-26T03:11:04.691-08:002016-12-26T03:11:04.691-08:00Soundproofing wall panel service is most widely us...Soundproofing wall panel service is most widely used technique to control the annoying and unwanted sounds but is gives desired results when you choose the right material for soundproofing after analyzing your precise needs. <a href="http://www.acousticboardindia.com/" rel="nofollow"> Soundproofing Solutions</a>Anonymoushttps://www.blogger.com/profile/14459263988935605166noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-58264263501622893662016-05-03T20:02:43.298-07:002016-05-03T20:02:43.298-07:00Hi - you mentioned in your post comment section he...Hi - you mentioned in your post comment section here that you also have insulation?

What I was really talk...Yes, thanks for clarifying. What I was really talking about here was workarounds that successfully dampen sound when you can't decouple from the structure, for one reason or another.<br /><br />From my own experience, I tried QuietRock 525 first. I removed two walls and insulated with fiberglass batts, then put the new walls directly onto the studs. I believed that this was all I needed, and the literature implies that this is all you need to do to block noise economically. The new walls do block most airborne noise, but I discovered that I was still getting impact noise. <br /><br />One of those new walls faces an adjacent apartment building, and someone in that building does a lot of mysterious slamming, which transmits into my room....presumably through the QuietRock as well as other pathways. I can also still hear some impact noise that comes from the bare wood floor in the apartment that's below me, but this might be coming through my floor, which is also not decoupled from the structure.<br /><br />For the other two walls in that same room, I tried a different approach: I added a second layer of wall on top of the first one -- but with a layer of Green Glue inbetween. I didn't demo the original wall --it's still attached to the studs. So two of my walls are 1" thick, with a layer of Green Glue in the middle, and the outer layer made of QuietRock 510. The other two walls are 5/8" thick, comprised only of one layer of QuietRock 525.<br /><br />With the combination of Green Glue and QuietRock 510 (the slightly thinner, less-expensive QuietRock), I got both mass + dampening, and it seems to also absorb some of the impact noise, not just the airborne noise.<br /><br />Now the question is whether or not Green Glue would successfully dampen the impact noise that's coming from the apartment below me if I put it on top of my subfloor and made a subfloor "sandwich"....attitunehttps://www.blogger.com/profile/09597645225969164299noreply@blogger.comtag:blogger.com,1999:blog-1086464886063984168.post-86271915015360936202009-08-24T06:45:19.307-07:002009-08-24T06:45:19.307-07:00http://www.soundproofingcompany.com/library/articl...http://www.soundproofingcompany.com/library/articles/neighbor_noise_ceilings/<br /><br /><br />Damping and decoupling are often confused or used interchangeably. They are, in fact, separate functions.<br /><br />Examples of decoupling would be the use of resilient channel, resilient clips + channel, staggered studs, and double stud construction. This is a physical disconnection of the drywall on one side of a wall from the other. Or the ceiling drywall from the wood floor above.<br /><br />Damping is the conversion of the kinetic energy travelling through a panel to thermal energy. Vibration to heat. This process robs the system of vibrational energy, therefore less is left to exit the board as sound again.Jameshttps://www.blogger.com/profile/09568619599485256434noreply@blogger.com
