Owens Corning 703

Try rock wool instead of fiber glass, products such as Roxul Safe n'Sound. The rock wool is less of an iretant than fiberglass.

As for facing materials, for my bass traps I bought fabric from Ikea and used it to cover the Roxul. Just be sure that the material has a tight weeve.

For my ceiling I do the following, I suspended two layers of insulation between the joists and left an air gap between the insulation and floor above. The first layer looking from below is a 3/4" thick fiberglass ceiling panel which is faced with a thin dimpled sheet of plastic. The plastic provides a clean surface for the ceiling. The second layer is 3" thick Roxul. check out my system picks to see the end result.

This has deadened my room substantially but, my room is small and it needs it.

I hope this helps

Thanks Nick, nice room. i have a large space in my basement, alot of area to treat. 703 is already tacked/glued between the joists - the is a Rives design, hopefully another 30 days it shoud be complete - been working on it since March...

Good luck with completion of the project. I hope you post some pics in your system page when it's done.

I would not hesitate to cover your entire ceiling with cloth to prevent any loose material from falling your way. I have been in the insulation business for over 40 years and you don't want any insulation fibers falling your way. They also make metal rods to help support the insulation. They are inexpensive, probably 20 dollars for your room, and extremely easy to install, just place between the studs and they are made pre cut to almost any size you need. The glue will loose adhesion over time so you should do something more to keep the insulation in its place. Owens Corning 703 is fairly rigid so I believe you will be fine if you cover the ceiling with cloth. Good Luck and make sure to post some pictures when your done.

Thanks Needfreestuff, that will be my plan. will be happy to post pix...if this project ever gets finished!
