In my opinion you should use polyurethane panels, but thickness 100mm. seems more suitable for your case than 80mm.
Polyurethane panels have water absorbance in 100% relative humidity a maximum of 0.2 volume percent. You can also use butyl mastic as moisture barrier for the outer edge of the joints.
SNi,
Thanks for replying.
Why have you opted for polyurethane?
Why do you you suggest 100mm instead of 80mm, is it because of higher strenght for the height or because of better insulation or both?
The thicker insulation will bring the price up.
