Hi,
You're right Terry ,the concern of papercrete roof of my first hive,and the "walls" of tje Ktbh,is good insulation and interresting strength/weight :The bees ,in the first hive don't fan or just 3 to 5 of them I saw,sometimes when it was really hot . Photos will come but not very often I am living 150 km away from the farm and I am working in a factory for the week...
regards
Claude B.
