Don't fit the standard hive
The protective covers are too small to fit over the standard hive.<br />I had to cut them length-wise to fit them around the hive.  There was about a 1" gap so I had to use duct tape to hold them on the hive.  I don't think they will provide a lot of insulation but when the sun is shinning it will absorb the sun rays and heat up the hive.  I would recommend them conditionally.
