47-55.1 Sound barriers / Interior insulation

[nvrdone]

Check out water heater insulation at Home Depot or Lowes. Both are peel and stick so the floors etc must be clean of all debris. Then add a layer of jute rug padding with carpet on top. you should be cool and happy. Also, make sure you use the silver tape over all holes and all gaps. It wont be as quite as a new Lexus, but its better that bare floors with a rubber mat.
