Engine Cover advice

[mcerick]

going to be tackling new carpet in my PS 190 before spring and upon doing so while i have the hatch off i would like to put the correct foam/insulation in the hatch as there is none right now except for the old glue. Is there a certain kind of Insulation or foam that is to be used in this area or what does everyone usually do? thanks in advance.

Check this thread out: Engine box insulation
Should have everything you need. Short version is that most folks use a foam rubber insulation from McMaster, with adhesive on one side, reflective foil on the other. McMaster. I think most folks go with the 1" stuff.
I don't recall how much most folks wind up using, but I'm pretty sure it's in the thread linked above.
