Sorry, no photos readily available of the installed insulation. I
bought the bubblewrap/foil insulation at Lowe's (competitor to Home
Depot, which didn't carry it at the time). It cost about $50-75 to
cover the pop top and windows if memory serves. I can't recall the R
rating either, but it was surprisingly high given the materials used.

Here is the link to the pattern/guide I used to cut the canvas
sections of the insulation.

Note the labels en francais. I presume this comes from the Quebec
vanagonites who probably know a thing or two about cold weather
camping.

Merci list!
