A better absorbtion mousetrap?

[tmcconnell]

Bonded Logic Bonded Logic - Natural Cotton Fiber Insulation makes an insulation from recycled blue Jeans that comes in 24 inch wide rolls 5.5 inches thick. They just sent me the absorbtion specs and the difference between it and 6 inches of oc703 look statistically insignificant.

The stuff is recycled material, totally nontoxic, and according to my back-of-envelope calculation a 24x48x 5.5" hunk costs 8 dollars. never mind its made from old blue jeans, which, one might imagine, carry a sort of karmic musical quality when placed in a studio. Seriously, has anyone heard about this stuff? The specs look like they were done by a legit measurement company, and absorbtion coeffecients are no more than .15 different than oc703 all the way down to 125.

At this price, and given its nontoxic (they just bake the ground up jeans with some sort of recycled plastic to hold it togther), I can see it would be easy and cheap to use in mass quantities. Happy to email specs to anyone. btw I don't sell it and have nothing to do with the company, but I thought if its real - its a boon for studio owners. I have a lot of 703 based stuff in my rooms and I don't like the idea of fiberglass floating around - and yes, I know there is debate about its safety. ted

i have been looking into this stuff for some time. building out my studio now...and considering going with the bonded logic stuff for my walls, and maybe some acoustic panels/bass traps. there are a few dealers near me in wisconsin.

curious as well if anyone else has any experience. in all my other studio buildouts...i have utilized owens 703 and 705. the specs do look similar. prices seem pretty reasonable as well...esp. compared to owens 703/5.

and...no itching........rock.

best,

fire rating?

This is a great idea, a long time coming. The only drawback for building hanging (semi-portable) wall absorbtion units is the weight. It is fairly heavy, at least compared to 705, etc. A while back, I got some recycled/shredded blue jean insulation and I don't recall there being any plastic mixed in, will have to check.

Cotton works well, and it's not new. The downsides compared to OC rigid fiberglass are:

1) It costs quite a bit more for the same size and thickness.

2) It is not as fireproof as fiberglass.

3) It is very floppy to handle, so you can't just wrap it with fabric and expect it to stay up and hold its shape.

4) It might rot over time if it gets wet. (Not sure about this.)

But acoustically it is excellent.
