I live in South Western Pennsylvania I can't remember the last time it went below zero. Usually the coldest it gets is in the teens.When your talking about insulation in the roof are you talking in the rafters up against the sheathing, Something like a styrofoam.

I'm Just starting to do my coop interior. I plan to use glass board on floor and white hardboard on walls. I know this has probably been discussed before but I don't know if I should insulate the walls or not. Any suggestions?
