Re: Anyone building or using styrofoam hives bodies?
"Yes lst 2 weeks have been very hard I have them in shade but it was 122 degrees yesterday it was 112 with 35% humidity it was ugly hot."
Insulating value goes both ways. With water nearby your bees will use the evaporation of it inside the hive to cool the hive. Then a well insulated hive will assist them in maintaining a cool house by keeping the heat out! Proper size vents become very important. I seem to remember reading that you need a 1 to 4 inlet to outlet size for correct air flow. Could be wrong on that. Watch the fanning and gradually increase the vent size until you only have a bee or two fanning. That is my method but have only been at it for two summers.
