ᐅ Energy Demand: Snow on Skylights & Shutters with Triple Glazing in Winter

At an outside temperature of -10 degrees Celsius (14°F), I also always get condensation on the inside of the window, and I am still looking for a solution. So far, for the few days a year this happens, I’ve just given up after airing out the room. But (see another post) I’m afraid that some mold might be developing there.

Are there any effective films available for such windows?

Here is the other thread.

You will only notice a negative effect of snow cover on a roof window in houses designed to maximize solar heat gains when it is sunny during the day.
You will see a positive effect in an older building with very old Velux windows. In that case, the extra insulation helps somewhat.

As I understand it, nothing further needs to be considered because of the snow. I am more concerned about the dark spots and the condensation when it is cold outside, and how to manage that.
