Jim, insulation was a factor. However I just wanted to try something new, remember I am a hobbyist. The price was reasonable, made for standard frames, controllable air vents, the weight is much less and appreciated by my back. So I thought I would try.
Will the bees abscond? I don?t know. Does the styrofoam smell to the bees?
I THINK the bees will like it I REASON as learnt to me by ID and Bush.
Blessings to all the Beeks.
