Green Fiber as bass traps?

[d.bop]

Hey everyone,

I stopped at Home Depot yesterday to see what they had as far as bass trap material. I was going to go with R-30 bundles stacked in the corners, but the bundles are too large for my room. As I was leaving, I saw some smaller bundles of something called "Green Fiber." It's blow-in insulation but it comes in a compressed "brick." Would stacking these in the corners work well for bass traps? Here's what the website says:

GreenFiber Cocoon Insulation is extremely effective in controlling sound transmission. This is especially true for airborne sound that is generated by traffic noise, airplanes, radios, televisions and conversation. This type of sound transmission can be significantly reduced by installation of GreenFiber Cocoon Insulation in ceilings, walls and between floors. In open attics, GreenFiber Cocoon Insulation easily molds around irregular construction and stays in place, fitting snugly against framing members and even moderate slopes.

GreenFiber’s insulation fibers have a natural tendency to trap air. It is also dense. The combination of these two characteristics provides effective noise reduction in walls and between floors.

Walls in new or existing construction that are insulated with GreenFiber Cocoon Insulation are able to suppress sound transmission much better than traditional batt materials. By completely filling spaces where sound can travel, GreenFiber Cocoon Insulation reduces the sound that can pass through gaps in batt-insulated walls.

Special effort should be taken during construction to make all walls, ceilings and floors airtight in order to eliminate any potential leaks for sound transmission. The staggering of outlets and plumbing is also recommended.

They don't have any absorption specs on their website, but the package does say R60 (though that's probably meaningless as far as acoustics go..) and it's basically made out of recycled paper.

Here is the website. http://www.greenfiber.com/

Does anyone here know if this would work well for bass trapping?

Thanks!

There is absolutely no way to know. Sorry man. You could always be the guinea pig, take some measurements and report back!

Thanks for the reply!

I think I might just go for it.. It's only $6 per block and it's pretty densely packed.


I'll post back here with measurements if I decide to try it.

I for one would love to see them, and I'd be happy to give you any technical help you need on how to do it.

Thanks Frank.

I was thinking of just keeping them in the package and stacking them. Then covering them with fabric so they look nice

Here's some more info from the Home Depot website:

* Assembled Depth (In Inches) : 13 in
* Assembled Height (In Inches) : 15 in
* Assembled Weight (In LBS) : 22.55 lb
* Assembled Width (In Inches) : 25 in
* Energy Star Compliant : Yes
* R Value : 3.7

And a picture:

*edit*

Too dense?

give the dimensions, the weight doesn't throw up any red flags. At first it did, then I realized that the stuff is 13" deep, which changes things completely. If the density is anything like rockwool, then you're looking at the equivalent of 3lbs or so.

Yeah the weight had me wondering too. The package, if I remember right, is a little more "stiff" than rockwool when you press it, but not much.

Either way, it looks like I won't be picking any up soon. I was able to fix the bass problem I was having by taking my traps off of their stands and setting them on the floor (covering the bottom tri-corner)

Maybe I'll return to this in the future, though.

Thanks again for the help. Room acoustics fascinate me
