I'm debating on putting insulation in my basement ceiling before closing it up with Sheetrock. I have done so much reading on the subject that I'm more confused now then before. The area is 22x26 and will be a multi function family/music area. I would like to limit noise transmission from going to the upstairs and from coming downstairs. I don't have the height and budget to go all out with clips/channel and DD/GG. I'm looking to possibly put insulation in the joist cavity and cover with 5/8 rock and at a later date add a second layer of Sheetrock when funds are available if it would be worth it.
I have read that using the cheapest fiberglass will give the same result as roxul safe and sound and it has been recommended to use R19 fiberglass. In my area roxul at one layer and R19 is a $30 difference, so pricewise it's a wash. What I'm not sure about is if r19 is equal to 2 layers of roxul or one layer of roxul when it comes to sound. If it's two layers of roxul then the fiberglass is the cheap way to go if it's comparable to one layer then I would go with roxul.
Also what has been anybody's experience with just using roxul SNS or r19 in there ceiling with just Sheetrock?
The ceiling also has recessed lights so I also wonder if any insulation would be worth the time and effort. Any input would be much appreciated. Thanks.
