I have a basement suite with very low celings. I'd like to have it better sound proofed. I wonder how much it would cost to spray insulation in the celing of a 600 sf suite?
Hi Sarah!
The answer to your question: First of all I would spray at least 2" which will give you roughly a R 14. So you are looking at $53.00 a sf.
Hi
I think Mike your cost is a little off .The last time I checked with a spray company the going rate is $1.50 per inch per square foot. That means at 3" you are looking at $ 4.50 a square foot. Contractors can also buy the twin tanks sets at Rona etc. for 400-700 to do a small job like this ....we have.

Why would you spray insulation or spray foam as some suggest if you're after sound proofing? Foam isn't a soundproof material and for less material cost you get sound and safe. Add resilient channel and perhaps a soundproofing type of drywall to finish the job.
Sarah
I agree with Ron. The last job that I had completed cost $4.50 a sq ft. If you budget $5.00 a sq ft you should cover the cost.

Sarah,
The spray foam isn't the best option for sound proofing. If you are concerned about cost, which is probably why you're asking the question in the first place, I'd go with a good batt type insulation like Roxul. This product is available at most home improvement stores.
Also you should understand that sound proofing isn't absolute in this application because wood also transfers sound. Having said that, anything you do will muffle the sound much better than leaving it "as is".

HI Sarah,
$2.50 to $3.50 sf an average. Can be sprayed. Its not a sound proof material yes its a good insulator but sound barrier no. You are better of buying the sound proof insulation at home depot, put in two layers, cover with vapor barrier so that nothing flies in the air, make sure the heating vents touching are properly sealed around vapor barrier installed.
Good luck.
Sarah,
I agree, spray foam is not the right solution the problem you explained. Roxul safe and sound is your best option. Sound travels through vibration so the more you dampen or eliminate the vibration, the more the sound proofing,
Resilient channeling and sound proofing drywall ( you may want to consider layering the drywall) along with the safe and sound would be my suggestion for you in your project.
Good luck Sarah
