what did you use for the insulation I see?



My buddy uses it in his truck... its for A/C ducts..
got it at Home Depot... its about 1/4" thick, maybe
a touch thicker... foil over a bubble rap stuff... it
works pretty good and light ... I sat in the drive way and let
it idle for about a 1/2 hour and it was good(I was
checking the cooing system)
