Doors and Windows - Condensation on aluminum skylight frame

Still haven't come up with a solution to this problem, at least not one that is easily feasable. What about covering the aluminum (2") with a closed cell foam tape say 3/16 to 3/8 thick? My thought is that this is enough of a barrier between the moisture in the air and the cold frame, I wonder if the moisture will find a way to condense between the aluminum and the adhesive of the tape. I've seen products simular used for weatherstripping. I'm not concerned about the visual as these skylights are 20' up. Dehumidifier in the house is helping.... thanks

Running properly sized dehumidifier and keeping humidity between 35-55%, lowering more toward 35 or lower to reduce humidity, will help. Run kitchen and bathroom fan vents at least 20 minutes after cooking and bathing. Make sure you have properly sized vents with enough CFMs for the cubic feet of area you are venting. Make sure vapor retarder is in crawl space and basement dry. Improve air circulation by turning on ceiling fan on low or by placing a fan in the area. If skylight is in a well, an exhaust fan would be helpful. The point is to get the air moving in the skylight. If skylight is recessed in a well and the walls are accessible in attic, insulate walls in this area to keep it warmer.

Condensation is more of a problem on older skylights with aluminum framing that does not have thermal breaks and the older single domed skylights. Replacing with one of the newer models would likely resolve the problem. Insulated skylights without single pane have fewer condensation problems. Skylights with insulated glass are more effective. Some skylights are ventilated. Others can be opened.

If you are in a cold climate open a window 1 inch and turn on bath fan for a day or two

Twelvepole, thanks, i think, yes replace the skylights is the best option but not feasable at this time, airflow would help...no one answered about the fact of insulating the aluminum to block the humid air from being able to condense on the frame...in theory i think it would work well. We have aluminum windows throughout the house and the only place condensation forms is on these 2 skylights, i've controlled the humidity as best as possible but hot fairly moist air is going to rise and voila condense on the frames.
