as brutally cold as it usually gets here -- in addition to the frigid temps, the wind started blowing midday -- i think I need more insulation (and forming a more complete vapor barrier) at the peak of the greenhouse if I'm going to be able to use the solar heating better on a day like today (and probably it would help on days that aren't so cold as well).
