    Default Foam in the Hurricane Zone ?

    I am currently building an unusual home smack-dab on the water on the Gulf Coast. It is an all concrete home, using The DAC-ART Building System (it is my second, I love it). Walls are a foot thick, all concrete.

    We are taking the approach that if the house is ever drenched, it can dry-out unharmed.

    Hurricane Ivan was a direct hit and the smaller guesthouse we had already built came thru just fine. Our yard was full of other's homes, but only took in a half inch of water.

    Anyway--I am considering using Icynene foam in the attic of the larger, main home under construction.
    The specifics: Trusses, no can lights, lots of tube sun domes, metal roof.

    I have been reading some rather dated discussions of open cell vs. closed cell foam, closed attic vs. vented attic and code. All of the situations that I read about were very different from mine.

    The curious can go toConcreteCottage to see photos.

    Can anyone offer any insulation advice to me?

    Look into using 2lb closed cell foam. This is a FEMA Class 4 Flood Resistant material. If your roof were to leak during a storm, the foam will help protect you. The foam will also help glue everything together.
