Sound deadening Material on the Cheap.

Two more items:
1) If you don't use carpet padding from a stinky old floor, you won't have any smell. Perhaps someone who's had this [roblem used old padding from under 'Garfield's Cat-Box'

2) Carpet padding absorbs heat very well. If you want though, put in the 'space-aged' stuff where there is heat. Better yet, though, & you'll laugh, but aluminum foil will do the exact same job.

I look forward to hearing all the interesting replies to this!
