I build in the basement that is intermittently heated. Still it doesn't usually go below 45 in the winter.

Glues get stiffer, epoxy and Titebond. CA doesn't seem to be affected although I don't use it much. The balsa and glue joints don't seem to be affected at all, but I build mostly with wood glue and after I have glued an assembly I wait overnight before I get back to it. As far as covering goes I bring the covering up stairs to get it to temperature and only cover the plane when the temperature is above 65. To my mind covering would be the most effected.

I don't paint much of my planes but I do know temperature and humidity greatly affect the outcome.

Just my experiences, hope it helps.
