Question on hive insulation

Hey beekeepers,

We have a customer in Maine (a newer beekeeper) wondering about insulating her hive using a quilt and perhaps pine needles in the roof cavity. Since this is fairly regionally specific, we were hoping to turn it over to the “hive mind” here. Is anyone adding an additional section to their hives in place of the inner cover for this purpose? We’d love some tips on this to pass along to her.

Many thanks :slight_smile:
