Galvanised roof for Optimal hive
- Dimensions: 51 × 51 cm, with an edge height of 5 cm. It creates an overhang of approximately 1 cm on the sides of the Optimal hive bodies.
- Material: Galvanised sheet metal intended for outdoor use. Supplied without insulation; therefore, polystyrene or felt should be placed inside the roof to prevent the hive from overheating in summer.
