Is the blueboard in direct contact with the bees?
Michael Palmer said he uses a 1 in Styrofoam for upper insulation but puts
the foam above an inner cover.
I am testing some of David Vanderdusen's (miteaway II) pillows this year.
About the same insulation factor plus absorbs moisture. many say absorbing
the moisture is as important as the R factor.
