Some great tips! magicbus, I had never heard of encapsulated batts -- I will definitely look into that. John, I could not determine whether Rockwool sheds moisture -- have you used it in similar applications?
And Steve, they say that EPS closed cell extruded polystyrene panels don't retain moisture -- is that not true? For example, a styrofoam ice chest seems to be perfectly dry after the ice water is poured out.
Agesilaus, I was also not aware of the alternatives to Liquid Nails. I like the idea of cementing the foam into place. The only downside is if I have to remove the stuff in order to fix a problem with the fresh water tank.
I know that the pontoons on pontoon boats are made out of closed cell poly that is exposed 24 hr/day to water and they do not become water logged. I used foam panels when I built my house and the panels were stacked outside in Florida weather for months and showed no sign of water absorption. So I am very doubtful of that claim.
