John Sayers' Recording Studio Design Forum Archive

Hi i'm buying materials so i can start building a home recording studio i have about 24 pieces of 2" thick owens corning 703 and 10 pannels of 1" owens corning select sound black board. 12 tubes of acoustical sealant plus a 5 gallon bucket of it.

My question is what do you guys think would be better for the inside of the walls? owens corning R-13 pink stuff or Roxul mineral fiber i want to try to block as much sound from coming in and out and yes i will be using double layers of sheetrock.

i already made about 10 gobos using 4 oz batting to cover the 703 and wood frames covered with burlap.

i also want to use the black owens corning sound select pannels as acoustical tiles for the ceiling what's the best way for me to mount these pannels on the ceiling?

also what do you guys think of the SOUND STOP FIBER BOARD MADE BY CELETEX? is that any good? it's supposed to be

if anyone is familiar with it please let me know cause i can get that near my house

Maximize your sound stopping power by using SoundStop® in homes and commercial buildings. SoundStop® stops sound transfer from:

Neighbor to neighbor: shared walls and
corridors.

Room to room: Noise-generating media rooms, workshops, laundries, and children’s bedrooms and playrooms; offices and conference rooms.

Outside in: Dogs barking, traffic and industrial noises, and airplanes.

Easy to afford SoundStop® adds great sale/resale value to single and multi-family home owners. Multifamily home owners benefit from SoundStop® by significantly deadening noise transfer through neighbors’ shared walls and corridors.

Nationally available SoundStop® achieves STC ratings of 42 and better when installed behind drywall.

SoundStop® is your earth friendly choice. The 1/2” x 4’ x 8’ or 9’ square edged fiberboard sheets are made of 97% organic materials including recovered hardwood or sugar cane fibers.

Check with code officials in your area. SoundStop® must be installed behind drywall.

thank you guys in advanced for your help...

if you have a limited amount of 703 then I would keep that for treatment inside the room and use the pink stuff inside the walls.

It takes mass-space-mass to stop sound - the celotex stuff is very light - it's not going to add much in the way of sound proofing, particularily at lower frequencies it will do absolutely nothing. I would save your money on that and put the money towards an extra layer of drywall instead. If you have a single leaf wall - then buy some resillent channel (it's dirt cheap) and mount that to the studs and the 2 layers drywall to that - this will give you a definate benefit. Remember to caulk the edges of every sheet as you add it. Leave a 1/8inch gap at the floor and ceiling and caulk that well.

i'm willing to spend the money and get a whole bunch of roxul insulation if that would be better than the pink stuff.
thanx

If you can find the right distributor, roxul AFB is not much more expensive than fiberglass, actually. I paid $150US for 500 sq feet, which works out to around $0.30/sqf. I don't remember exactly what the Home Depot price is, but i seems that I spend around $40/bag for R13, and I'm guessing a bag has around 160sqf, based on how I used it in my garage.

In southern California, you can get roxul from Inulation Wholesalers in Pomona. They seem to have the best price.
