Sound- absorption or reflection

[timvasqz]

Not too far fetched. My cummins engine computer is cooled with
diesel fuel. I am just curious where you were transfering heat to
with your 'insulation heat dissipation remanufacture redesign'

heat is transfered and lost to other objects. for one thing to lose
heat somthing else must take it. its a calorie calc. when you
insulate to keep heat from the interior of the bus where does that
heat now go?

some times when an interior gets hot and calls for modification it
is an overlooked sign that the heat producer has other issues causing
excessive heat. KurtH can atest. in a genset the genhead may be
cooking or engine exhaust is screwed up.
