We're heading into our third winter and have had no issues with cold
this far. We build our hive bodies from 5/4 rough-cut pine and that has
plenty of thermal mass to keep things where they need it. Just close the
bottom board and mouse-screen the entrances. We're doing a bit of
experimenting with a variation on a warre quilt for the top and it looks
promising. One hive lost its roof in a New Year's gale and spent a week
in -30C overnight temps before we could get over toe check on it. Last
winter, that same hive lost its bottom board at some point and they've
come through with flying colours. Needless to say, that's our breeder
As Tom mentioned, a certain amount of air circulation is needed to
remove any moisture. It's kind of gratifying to see icicles hanging from
the bottom board in January.
