Re: Acoustic Insulation for engine room?
Did a study on this subject several years ago, and what I found was the most effective sound deadening composite is lead foil sandwiched between 1 inch (or more) of foam and secured with a pressure sensitive adhesive.
Yes, psa's have sound deadening qualities too.
Hope this helps. Dick
Flyby, Is that lead foil in the middle between TWO layers of foam? Can you make this up yourself in the engine room or does it have to be pre-manufactured sheet goods?
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
