I reached chapter 17 in Thermal Shutters and Shades last night and 
resumed this morning.

Dr. William A. Shurcliff begins this chapter with your everyday  roll-up 
window shades, stating that they can reduce heat loss by 20 percent. I 
quit reading. There are several old roll-up maps in the barn. I closed 
the book and went treasure hunting.

I found three, all sized just a bit larger than my windows. Published by 
Denoyer-Geppert in 1960; a civil war, reconstruction, abolition, cotton 
production, per capita wealth map; a western movement and colonial 
commerce and industries map; and a Europe 1916 and Napoleon map. 
Googled, they sell for about three hundred bucks apiece.

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 My book is outdated in that respect.

I could probably sell the maps and use the money to buy something more 
modern I suppose but would it have the inset drawing of the Virginia 
Campaigns with a scale of 13 miles to an inch?
