What is the best way to soundproof a home between 1st and 2nd floor (apply Batt or spray foam)?

sRpHrL8a6C | Posted in General Questions on

Does Green Glue really work for soundproofing? Someone recommended that I use two 1/2 inch sheetrocks and glue them with Green Glue for a media room and that will help. Not sure if you have any recommendations in that regards….Thanks.

    I can't help you out with your insulation question. But have you heard of "quietrock"? It's made specifically for sound proofing.

    And its heavy as (insert 4 letter word). And pricey. Install the board on resilient channel with sound batt in the joist cavities. Should be good for 99% of us

    Every time this subject comes up on a forum, the "sound guys" say 2 things: block air ways (under doors, elect boxes, etc) and get mass in the way any way you can. QuietRock is mentioned often, as above.

    This site has some good reading, especially on what to AVOID doing:

    For example, the last thing you want to do is create air cavities that induce resonance (why previous posts mention filling cavities)
