We are installing the roof to the coop this weekend. It will be our last step of construction and then I'll get to start making it pretty with paint, inside layout & decor! We were given bubble wrap insulation for our roof and it looks like will will have quite a bit leftover. Can I use this on the walls as well? I was thinking I could cover the insulation on the bottom 2 ft with FRP (the stuff used on walls in commercial kitchens) to keep it from getting soiled. Would that be high enough for both cleanliness and safety of my girls? I know chickens will peck/eat other forms of insulation, but I'm unfamiliar with the bubble foil. It's a raised coop, so insulating the floor won't be a problem. It's a 4x8 lean-to with the front wall at 6' sloping to 5'. It's 2' off the ground and the walls are 1/2" OSB (floors are 3/4"). I plan on putting siding up in the fall before the first freeze. I also have five (2'x1') shutter-style windows, secure & vented with hardware cloth. We have temps that get above 100 in the summer with high humidity, and winter temps can stay below freezing for days/weeks at a time. It does snow here in western Kentucky quite a bit for being considered a southern state! With the floor and ceiling both insulated, would I even need wall insulation? Would it be overkill? Any suggestions are appreciated! I'm new to chickens and coop construction, and this has been a lot to figure out. I just want my girls to be happy & healthy!
