[QUOTE="Jerkbait, post: 519050, member: 36094"] I kind of like the idea of thin foam board with pour foam on top. Then I can make sure I have as much foam under the deck as will fit. But the data on the pink Owens Corning foam is interesting. If that 9216 is converted to cubic feet, it's 5.3. And if it weighs 9 pounds, that's about 1.7 lb/cu ft. The pour foam is supposed to be 2 lb/cu ft if expanded properly. The foam board is actually lower density. So it would seem that the two compare favorably. Actually, I just looked @HD site and the spec is 7.5 lb for 2"x4'x8' Foamular NGX - even more interesting. It's also rated for below grade service and is supposed to be 'highly moisture resistant'. Owens-Corning says: "Non-diluted gas can affect the Foamular". So that's the down side I guess. I dont expect to have undiluted gas in the bilge in any quantity. Something to watch out for I guess. Thanks for the good feedback guys. It helps alot. [/QUOTE]
