a hollow core door can be filled with the sprayon insulation stuff. Drill at least two holes (large enough for the nozzle) the second one alllows the air to escape and be relaced by the foam insulation.

Then if you treat the door with polyurethane, be sure to put on multiple coats (6 or 7) and do all the edges. The edges are where a lot of the moisture exchange takes place.

edit: and use steel wool between coats for a really smooth finish.
