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 My book is outdated in that respect.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?
