Soundproofing Under Hardwood Floor?
I’m finishing my bonus room above the garage. The subfloor is Advantech, the floor will be 3/4″ solid oak. The bottom of the subfloor (ceiling of the garage) is sprayed with 2″ of 2# closed cell spray foam.
Do any of you or anyone you know use soundproofing under their wood floor?
The room is for music & movies, & so I am just trying to isolate it from the house as much as possible.
If this is recommended, can you all provide some good quality manufacturers of soundproofing for this application?
