If you live in a cold climate changing duct work to insulated flex ducting may be of help.

With all the warm and moist air that goes through the 4" fan line, a lot of it is going to condense back into water. Not much you can do except route the 4" line so that most of it runs downhill to a gable or soffit exit point. Insulating the vent hose can help, but since it eventually will open to a 4" exit hole to the outside cold, it will still condensate and run back into the house if the majority of the hose runs uphill.

I would make sure the duct line goes UNDER any insulation in the attic. This will help steam to not condense also. We have a vent in our main floor shower/bath room, and it is pretty level goes out to a soffit area and under the insulation. Have never had a problem with moisture.

The right size vent fan (for the space) is important too, as it needs to move the volume of moist air fast.

thanks we will be working on it today and let you know how it comes out. thanks again
