fiberglass from home depot...

[goodbyebluesky]

I stopped by Home Depot today thinking I was going to ask them about ordering some mineral wool, or 703 fiberglass to save on shipping charges.
I ended up looking around and saw the fiberglass insulation they carry, and while most of it was much too thick to use to make panels (6" or thicker) they had some that was 3.5" thick, in a big roll for under 12 bucks. It came out to $0.29/sq ft!!
How can I tell how this stuff would compare with 703 or mineral wool? I'm tempted to give this stuff a try since price is seriously the biggest factor in my home studio, because it has to be.

It's not the same thing at all I don't think.

Well, can anyone elaborate? Either way, I think almost any type of fiberglass would absorb as well as foam. And at this point, buying mineral wool or 703 and having it shipped is just not an option.

There are a lot of threads in this forum that alreaedy elaborate far better than I could.

Yes, definitely do a search on mineral wool or rigid fiberglass.

I think I remember someone (someone knowledgable about this) saying that If you stack enough of the fluffy stuff (f/g) it is of some benefit.

Here is a cool little trick.. Buy the fluffy fiber glass in the rolls and stack it from floor to ceiling in corners (leave in plastic).. You can then build a false fabric wall in front of that...

It is nowhere near as dense, so it won't stop bass frequencies as well as rigid fiberglass. Leaving it in the roll does work better as it remains compressed.

If you keep the fiberglass in rolls it can be an effective bass absorber, but the plastic wrap will prevent it from absorbing highs... if you decide to somehow hang the fiberglass from your walls the fiberglass will absorb highs, but it must be very thick in order to be effective... I'm talking up to 16 inches thick... so, when you improvise it can be effective, but not practical... I suggest searching a little harder for some 703...

also, these are the NRC ratings of the home depot (Owens Corning fluffy pink) fiberglass (unfaced, 12 inches thick):

125hz 250hz 500hz 1000hz 2000hz 4000hz
1.14...1.09...1.09....0.99....1.00.....1.21

I know where you are coming from regarding cost. I used standard 3.5-in R-13 and 9-in R-30 insulation on the walls and ceiling, respectively, of my studio. I know it isn't the best, but it is better than nothing.

Speaking of Home Depot, they also sell a product called CertainSound insulation. This appears to be denser, but the cost isn't much more. I went with that around my isolation booth.

Purists will probably scream at me for cutting corners, but you have to do what you have to do. I am lucky though: my studio is in a house in a rural area away from other houses. Thus, I'm not concerned so much about noise getting out of the structure.

You can also try doubling your drywall.

Ask at Home Depot for Roxul Drainboard, or Roxul Safe N Sound. Awesome stuff, barely more expensive than the pink garbage.

I'm almost positive that won't be available to him... 99.9% sure. He's from Florida, and the Roxul products are usually only available up north... apparently, due to shipping costs from Canada to the southern US, Roxul was loosing more money than they were gaining it...

On a roll? 3.5"? What was it called? I'm getting stuff like that for my studio. It's called bonded logic, ultratouch. It is made from recycled jeans so wont damage health and wont make you all itchy. It has abosorbtion coefficients as good if not better than many of the 4" and 6" rigid fiberglass'. This is the spec sheet for it. Look at Acoustical performance, at 3.5".

I read about that stuff before... it's great stuff, and cheap as hell. Like you said it wont make you itchy and there are no dangerous particles you have to worry about breathing in, and it's NRC ratings are amazing... I tried looking for some myself a while ago but it wasnt for sale yet... let me know if you find some....

[pandamonk]

I found a company here in the UK that sells it, but it's pretty expensive. Moreso than Rockwool, Knauf, etc. But it'll be worth the extra £££ for my mum not to worry about me breathing dangerous particles etc. I was wanting to cover my whole control room in the stuff, but it's too expensive so I'm just gonna cover the back wall, reflection points, and behind the speakers. Where are the best places to cover in a "live" room? Obviously bass traps, but where else? The rooms are tiny, like 6 1/2' x 7 1/2' for control room and live room 1, vocal booth is like 2' x 9', lol, and drum booth is 6' x 9'. I know it's tiny, but that's all i got to work with.
