just be aware that many insulation types are now banned on boats due to their flammability, and will fail a boat safety certificate with them fitted (and hence be unable to get insurance).
the spray foam stuff is the standard and it is fire retardant also.
i think most stuff now is fire resistant but just thought to double check when getting stuff from builders merchants which is designed for other uses.
