Using your plan may work as well. For insulation, if you can't go with the foam board shown in that link, would wool insulate it enough? I love wool, but I'm not sure it would be capable of preventing freezing water. If you could get your hands on a couple wool fleeces, maybe you could use them? Alternatively, wool blankets and sweaters can be found at thrift stores often. If you aren't sure if something is wool, you can test it by pulling some fibers off of it and dropping them in bleach. Wool dissolves in bleach
