The wrap comes from B&B honey in Huston Minnesota. What you see is the 23 inch wrap and it covers the two deeps, the feeder rim, the sound board and 2" insulation over that. I duct tape it tight after I put the mountain camp sugar on about now and check again in mid February to see if they need more. It is supposed to be R 3.7 insulation but the durable plastic to keep out the wind is more what I want. I am reusing them for the third year and they still are holding up. I staple it and remove staples with hive tool as I do not try to get them sunk all the way in and use 9/16 length. The system is working well for me, but might not in wet country. With the hole bored under the handhold in the upper box, I think it would. I have only found the sound board to be soggy on a couple hives. Never figured out why them and not the one next door.
