I have a skylight in a small room. This is basicly a pyramid shaped
0.8m square window at the top of a 0.5m vertical tunnel.I know from last winter when I was decorating and had the radiator off that the room loses heat and gets cold quickly in winter. So, it is probably worth working out how to insulate that skylight.
What occurs to me is to build a frame and put a couple of sheets of clear plastic `glass' at bottom of the `tunnel', ie at ceiling height.
This is not beyond even my limited abilities, probably, on a good day, but I suspect condensation in the chimney between bottom and top windows might be a problem. Is there an obvious solution to this which hasn't occured to me?
I'd rather not do _anything_ to the external glass part as that would involve going up on the roof which in turn would involve going up a ladder next to a 4 floor drop, and, being one of those who has to build up courage before changing a lightbulb, frankly I'd rather freeze to death.
