Ultimate Insulated Inner Cover

Made of technopolymer construction that will not rust or rot. This inner cover features 2" high-density EPS foam with an R-10 insulation value. As a year-round option, it helps retain heat in winter but minimizes heat in summer (meaning less stress on bees). 1.5" center hole for ventilation and optional feeding, as well as upper entrance options. Simply too many features for the average catalog entry!
