Here is a photo of mine. Tar paper, bubble wrap, pallet wrap. Foam board on top of inner cover with center opening cut to coincide with opening in inner cover). Kelley's Ventilated super on top of that - with 6 of the 8 holes closed off. (Cuts down on down drafts but allows warm moist air to escape).
Having taught Earth and environmental science for 30 years, I thought I'd duplicate a "Greenhouse Effect" on the exterior of my hives. Short wave visible light waves pass through the plastic, hit the black tar paper, turn into long wave infrared rays (heat) which get trapped inside the plastic. Temperature goes up. That plastic is warm to the touch on the coldest days. (Think about why a car interior is so much hotter inside on a sunny day.)
I try to work with the natural convection currents inside the hive. As warm moist air rises it will escape through the vents I provide. Foam board on top of inner cover keeps it warm and prevents condensation on the INSIDE of the inner cover because the warm moist air continues to rise up through the center vent of inner cover and foam board. When I open the top cover, there is condensation on it, NOT the inner cover.
