Insulating is ok as long as you ventilate it well too....otherwise youll make it worse as warm air carries more water vapour,,,cant get out and it hits a non pourous surface and turns to condensation...
The visqueen idea wouldn't work either, as yes it will catch and channel water from above, but will have its own build up underneath so wheres that gonna go?
