Will R-13 work?

[Phoneboy]

Hello to all

I am almost finished with my 14X14 "Dog house" (9' ceilings). I plan to use it as a Studio/hide out. My question: Would compressing 2- 3 layers of R-13 work in place of 703 pnls. I ask because I got a cpl rolls
of R-13 from a guy and I don’t have any other use for it. I believe I would have to separate the Fiber Glass from the paper.

I tried a search prior to posting but did not find an answer. Any advice would be appreciated


Thanks
Steve

it would work to some degree, but probably not very effectively as a bass trap, although if you use enough of it, you would get the effect, i would imagine.
it is often said that enough "fluffy" insulation will be equivalent to the density of hte 703 style. Like if you stacked rolls in the corner, floor to ceiling.

Thanx daav

That answers that ?.

R-13 is about .8lb/cu ft. 703 is 3lb/cu ft. However, it's more than just density. If you were to take 3 layers of R-13 and compress it so the total thickness was about 6", you'd have a relatively effective bass absorber.

Yes - you'll want to remove the paper (unless you want to leave 1 layer on the piece that faces the room if you're wanting to minimize mid/high frequency absorbtion)

bpape has it right. Unfortunately finding a way of holding the compressed R-13 in place while still leaving it exposed to the sound waves may be more trouble and expense than its worth. Maybe just add some extra insulation to the attic space and let it do what R-13 was designed to do.
