dalpozlead Posted January 12, 2014 Share Posted January 12, 2014 Hi guys, this is more of a random question about the general usage of rockwool (or stonewool) in US & Europe homes and studios. Here in Brazil we don`t largely use this materials, but I`m reinforcing an existing wall with a drywall filled with rockwool prepared from a specialized company, this will help me to increase the sound barriers to my neighbors. Is this kind of construction and the use of the rockwool insulation common in other parts of the globe? I wonder if its healthy safe :-) sorry for the handyman question :-) Tks!

J. Dan Posted January 12, 2014 Share Posted January 12, 2014 I think you'll get a better response on the Ethan Winter Audio Expert forum over at the EQ section Here. There are lots of discussions over there regarding home studio construction and acoustic treatments. Dan Acoustic/Electric stringed instruments ranging from 4 to 230 strings, hammered, picked, fingered, slapped, and plucked. Analog and Digital Electronic instruments, reeds, and throat/mouth.

dalpozlead Posted January 13, 2014 Author Share Posted January 13, 2014 Tks, I was also hoping to get feedback on the general usage, not only for the sound design :-) Link to comment Share on other sites More sharing options...
JeffLearman Posted January 13, 2014 Share Posted January 13, 2014 The hardest to block is the bass. To block it, you need two things: mass and flexibility. One of the simplest add-ons (that is, without rebuilding the wall completely) is to hang drywall on these little spring-like things (Dan, do you remember what those are called?) Ideally, IIRC, you have the regular drywall, and then add another layer of drywall with space between, and the new layer is suspended on these springy tabs. Also, IIRC, you can hang two sheets instead of one, for additional isolation. There's a special rubbery material you place between the two sheets. I knew this stuff once upon a time but those brain cells died. Link to comment Share on other sites More sharing options...
JeffLearman Posted January 13, 2014 Share Posted January 13, 2014 By "rebuilding the wall completely" I mean rebuilding the studs. The best approach is to stagger the studs so that each stud attaches to only one wall, rather than the normal two. That is, you make the wall an inch or so wider with twice as many studs, half for the wall facing one way and half for the wall facing the other way. Probably feasible only for new construction, requiring wider boards for top and bottom caps, but who knows, maybe a clever carpenter could fit it into an existing wall somehow.

theGman Posted January 13, 2014 Share Posted January 13, 2014 This thread has gotten me interested in doing similar. Besides what is being disussed here, are there a few other sites which go over this topic? I did Google this, but there were so many I was hoping some of you would know the best ones.
