For the cold months I put up those 2 inch thick 4 by 8 Styrofoam sheets all the way around. On the North side I do 2 thick so that is 4 inches of those sheets, Works Great in this WI. climate I have not frozen up yet in 10 years and that is sometimes at 40 Below Zero. Then in the spring I take them down store them and use them year after year after year. MUCH better then having to MESS with Straw bales and the Mess they create ~!
Added: What a difference that makes on the floor temps too for the most part I just wear socks on my feet in the winter vary rarely have to have slippers or shoes on. Nice and Toasty.
