Unless you have some exotic, thinly feathered breed, insulation is a TOTAL waste of time and money.  Chickens already come equipped with perfect insulation of their own.  They don't need any help from us, at all.   Just give them a dry, WELL ventilated (Not a wind tunnel) place to live, and they will be totally fine.  The only thing insulation is good for in a coop, is to give rodents, a nice and cozy, well hidden place to live.
