>We found that, across eight experimental apiaries, covering honey bee hives with corrugated polypropylene board and topping them with foam insulation decreased food store consumption and improved overwintering survival compared to identically managed hives without covers and insulation.
This is what I do. Last winter we lost only a couple of hives, due to queen failure
