    Hi Guys , anyone have a datasheet to compare the water absorption of XPS vs PVC or PET foam? I don't need shear strength, compression or delamination problem jut that keep out the water like a PVC closed cell. The lamination is epoxy.

    I've also seen <0.7% on datasheet for Jackodur XPS. I'd speculate it would also retain more water if you cut it with a knife or saw compared to if you cut it with a hot wire.
    But if it's encapsulated with epoxy it shouldn't matter.
