When building a sound proof room has anyone tried using "Roxul Insulation" on the ceiling?
If so, how has it work out for you?

I'll let you know in about a week.

I finally start insulating the ceiling this week after 3 months of building up the mass between my ceiling joists and completeting the HVAC.

Roxul is a brand, so you'll need to be more specific with the exact type of insulation you plan to use. For example, there's Roxul Acoustical Fire Batt (AFB).

Roxul is what I've used in my construction: http://www.roxul.com/sw34142.asp

Here is the link to my thread... http://www.johnlsayers.com/phpBB2/viewtopic.php?t=839

If you have a tough time getting your hands on Roxul Acoustical Fire Batt (AFB) - ≥2" (2.5 pcf), a similar/competing product is Thermafiber Sound Attenuation Fire Blankets (SAFB) - Nominal Density (2.5 pcf).

Also, for inside of walls/ceilings if you can't find the heavier stuff the normal, fluffy fiberglass insulation will come within 1 or 2 dB of the same performance; it's only in the room itself where the higher density stuff makes much difference... Steve
