Rigid Foam Board Insulation

A high-density, moisture-resistant insulation board designed to sit directly above the inner cover. By providing a superior thermal barrier at the highest point of the hive, it prevents critical cluster heat from escaping and eliminates the "cold ceiling" effect that causes deadly condensation.

• Pro-Tip for Northern Ontario: In our region, heat loss through the top of the hive is a major cause of winter mortality. Adding a rigid foam board ensures that rising warmth stays with the bees rather than hitting a cold outer cover and turning into ice. For best results in Northern Ontario, pair this with an upper entrance to allow any residual moisture to vent out safely while the heat stays trapped inside.
