So, I'll go back to my book now but suspect that if I glue aluminum foil to the backs of my maps they will reduce heat loss by about fifty percent (if sealed well at all edges of course). There must be a modern film that I can buy instead that's easier to apply and probably more efficient. My book is outdated in that respect.The maps sound like a neat idea. And it sounds like they are at least close to the right size already, that's a boon.
