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
