Inner Covers

All three of these inner covers are used in conjunction, each serving their own purpose. the first one, the bees propolis up the edges and this provides a screen, so that in winter you can open the lid and not disturb the bees. The second sheet, an insulation sheet is able to absorb the heat and reflect the heat out of a hive and is placed on top of the clear sheet of plastic. the insulation foam is like the bread in the sandwich, it absorbs and reflects heat and is placed between the clear plastic sheet and the insulation sheet.
