Hi, I am also new, since May, and live in New York, downstate, Long Island. Not very difficult that I can see. I plan on putting fiberglass insulation on top of my top bars in the roof area, and then on the bottom end I have a hinged bottom bracket so I can clean the entire hive, and it is also screened below. So I plan on opening up the hinged area and also placing a very thin layer of either fiberglass or a thin packing material that is rolled and air filled. not bubble wrap but more like a foam insulation kind of like what they use for computer wrapping.
Larry, good luck
