My laundry room is an addition to the house. It has had some mildew problems before we bought the house. We have removed all the interior walls (paneling and fiber board) and the linoleum off the floor. The walls are wood slats on the outside with no insulation between the studs. We live in TN. What is the best way to finish the room..insulate and use mildew resistant drywall on walls and ceilings? The room does not have heat but has a doorway (no door) to the house so there can be some airflow. Dryer is vented outside. I am concerned the laundry room will get mold and mildew again. Thanks.
