I'm doing the same thing and I need to know the name of that insulation. I might call one of the darwall places in town and ask. I'll let you know

MASS LOADED VINYL (http://www.soundproofing.org/infopages/flooring.htm)

I used this in my old house with 2 layers of drywall and while watching movies at a very high volume the room was almost unheard of from the rest of the house. Although pricey, very effective and when combined with regular insulation...cant beat the combination.

Shit! :

GOOD: Super Soundproofing MLV: Same as above for homes and offices, but without the foam backing. Somewhat less expensive at $5.88 per running foot. ($1.47 per Sq. Ft). Available in 4' widths X 25' lengths: $147 or 4.5'X30' $6.60 per running ft. Roll: $198.75 Also available with peel-off backing! (Eliminates the mess and odor of adhesive and is easier to install on walls.) Available in 2# weights too. See the buy button.

BETTER: Super Soundproofing MLV: Useful for vehicles, too. 1/8" thick. It has a 1/4" open cell foam bonded to the underside to provide additional vibration isolation. $8.63 per running foot: (54" wide). ($1.92 per Sq Ft). PN 09-00004-F 30' Roll: $258.40 09-00004-1

BEST: We also have Super Soundproofing MLV- same as above but with 1/4" closed cell foam bonded to the MLV for superior noise damping. $14.63 per running foot: (54" wide). ($3.26 per Sq Ft). PN 09-00006-F 25' Roll: $365.75 09-00006-1 30' rolls are only available in our San Marcos, Ca warehouse.

Flammability: It meets certain UL requirements, but is not FAA approved for certified aircraft. (Homebuilt OK).

i'm looking for something good, but not pricey. i havn't even looked at home depot yet, would just regular insulation do the the trick??

The best soundproofing I've done in the past is in multiple steps

#1 insulate with sound insulation - rocksol? I believe

#2 1/2" fibre board

#3 sound bar/resiliant bar

#4 drywall

I would call Winroc in Calgary at 236-5383 and ask them about Sonobatts if you want the best bang for the buck!

I wanted to bring an old thread back from the dead. Anyone else have any other suggestions on what works? I'm basically looking at sound insulating a master bedroom and the basement (I want to minimize the sound of footsteps and water in the pipes).

I'm thinking of:
1) Buying the Roxul Safe 'n Sound from Home Depot / Rona
2) Putting up some drywall for sound absorption (not the QuietRock - since it's ungodly expensive but maybe something else -- anyone w/ any suggestions?)
3) Maybe some sound absorbing putty or caulking around each of the outlets and vents.

I've got a B.I.L. that's an architect and we had this discussion while building our current house. Some of the best sound proofing steps happen with the framing but assuming you can't reframe an existing house, insulation, then sound-bar, then DOUBLE LAYER of drywall.
