the rolled faced insulation on the ceiling of my unfinshed unheated basement is on backwards(vapor barrier facing down instead of up towards the 1st floor),1st floor is uncovered hardwood. Insulation must be at least 25 years old and my basement gets very humid may-aug.( I run a dehumidifier) Is there any good reason for me to flip it over or even remove it altogether? I count twelve rows that are each 16 inches wide by 36 feet long.

Best Answer
The vapor barrier may have been done correctly; it depends on several factors like temperature, whether the basement is a living area, or if is a laundry area or has other sources of moisture build up. You need to ask your local inspector.
