We had a replacement skylight installed by Artistic and have problems with excessive condensation when the temperature drops below 0 degC. This is not a light misting around the corners and edges, but large drops which cover the entire inside surface of the skylight and have to be removed every day. The humidity within the house is kept below 40% and there is not a condensation issue with the other windows.
A shade is closed at night to limit heat loss and deal with the cold draft that comes down from the skylight (as are blinds drawn on our other windows). Artistic claims this is the problem, but even if the shade is left open, condensation still occurs, although not as severe. At lower temperatures, even having the shade open is ineffective. Furthermore, I do not think that excessive heat loss should be tolerated just to accommodate the skylight.
Artistic makes the dubious statement that humidity at skylight level can be up to 100x greater than in the rest of the house. If this were true, then an incredibly low 10% house humidity would translate to an impossible 1000% at skylight level. Artistic also makes the ridiculous suggestion to use a dehumidifier in the winter.
I believe that a product should be designed for real world conditions rather than expecting the customer to bend over backwards to accommodate the product. I cannot recommend Artistic skylights.
