That's hard for me to answer. In this part of the country we don't wrap our hives with anything. Instead we provide windbreaks. A line of trees between the hives and the north wind work well. I do that. In the back yard I put up tarps suspended between T bars. I know others that use T bars and stand up wood pallets. Some use hay bales or snow fencing. I think black plastic would work and it would be inexpensive. I don't know about your area, but you may have bees thinking that is warmer than it is. Cleansing flights could be fatal when the bees come out and end up face down in the snow. We see that here even without wrapping the hives. I would make sure I had adequate ventilation so condensation can escape.
