doing a basement remodel on a five year old house with the all ducts already in place and on the cold air return there is a 4" insulated flexable duct coming in from the outside with fresh air, the cold air return is condensating. this area is to be enclosed in drywall. would wrapping the cold air return in insulation stop this?? if so what kind of insulation would be best?
thanks

If its condensing inside the return drop. You'll need to add a motorized damper to it. That only opens when the furnace is running. Aprilaire makes a damper and control system that works great for controlling fresh air.

Reflectix will work. Or regular duct wrap.

whats happening...is just to great of temp difference between outside air. and r/t air. how far is this pipe go? before it enters ur r/t air? it should be wrapped and should be the farthest away u can get it in ur duct. this will give it a chance to get up to temp for u. before condensation.
