Hah! FINALLY just now getting around to my panels. (took me long enough!)
I have the panels built, and have the insulation (SafenSound) and fabric to cover.
So, a question about fabric . . .
I know everyone says that the fabric should be permeable enough to be able to blow through (a rough gauge of how permeable it’ll be for sound waves – don’t want it to be reflective). The fabric covering I’ll be using is fine there.
However, I also got some landscape fabric to finish the backs of the panels, and I have enough that I could also do a layer of that extra fabric on the front, underneath the finishing fabric (to contain microfibers). I can blow through the landscape fabric as well. If I double up those two fabrics it’s tough to blow through. I’m “thinking” it’s okay though: both fabrics are permeable, and doubling them up should lead to more absorption (since neither fabric, separately, has a reflective quality). I mean, heck, I can’t blow through all of the insulation either!
But I just thought I’d be on the safe side and run it past y’all. Would it be reasonable to double up these two fabrics on the front of the panels?
