Above are links to a product that I read about on the University of Minnesota website.  They use this above their inner covers as a means to absorb moisture and let it out of the hive.  This has me intrigued.  It reminds me quite a bit of the quilts warre and some lang keepers use, but it looks much easier to deal with.  My thought right now is about my new poly nucs.  I have a topic in the equipment forum about poly nucs I am making.  There is this trade off with poly nucs and no upper entrance of a possible venting issue.  Is this something that will get you the best of both worlds?  Put this above the nuc and you poly roof over it.  Moisture becomes less of a problem and you still get the benefit of all the insulation.  One of course could use these on wood hives as they suggest in the u of m handout I was reading.  Thoughts?

if it's what i think it is it breaks pretty easily.

This product is no longer affordably available in my area.  I use soundboard as a substitute.  It does break if you are not careful.

That sound board is nasty stuff to work with.. Makes more fine dust than anything I've ever cut before.
