Insulated Beehive Ventilation Affect
This study was performed by the University of Montana and took a small sample size, however the data collection was well done and performance of the hive and the action of the moisture can be backed up by building science.
"Beehive ventilation is always necessary to ensure bees have an acceptable environment. But the placement of this ventilation in the floor of the hive instead of the upper portion of the hive may prove to maintain more optimal humidity and temperature for the colony. This combined with greater insulation like that in polystyrene hive bodies may lower the oxidative stress of the bees and increase survival rates based on the data recorded. "
