My brother in Alberta is a general contractor who sent me a bunch of literature three years ago when I was doing a major remodel. I have since lost it. But I will ask again.

Ps it's not that the beaded foam dosen't absorb moisture it does but it also dries out again at roughfully the same rate. The other absorbs it much slower but gives it up even slower.

Nick, do you have a source for that? AFAIK there has been no data suggesting that.
|In the housing construction industry things are changing due to long
|term use experience with foams. The blue and the pink foams are proving
|to slowly take on water and keep it while the bead foams breath better.
|So after twenty years the simple old beaded foam is still almost like
|new in say a roofing application while the Dow sm and like products
|have lost significant r value because of moisture loading.
|How this applies under water in boats I have no idea.
