Hi David and Troy
The Thermal insulation is easy to put up and take down. You will want
to take down any or all insulations from time to time to dry them out
due to condensation and reduction of mold and mildew to let them breath.
I have looked into temptrol but it is aluminum and if you do not face
it the silver ( aluminum ) will make the canvas it rubs against Black.
It could be done but all you really are doing is a thin insulation
with no real r- Value but you do get radiant reflective heat. It
would work but be a bit less effective. I made the R-8 to go Extreme.
I could make one with the thin fabric and back it as well if you
like. It has been a few years since I contacted the supplier for
temptrol but could again. Not sure if anyone is interested in a more
basic version.
Can make it the same way and attach the same using my same pattern.
So it is not a biggie.
I do have another material called solar shield. Silver on one side
and white on the other. color will not wear off and it is strong by
it self. We use to make the out side thermals out of that.
I still like my R-8 Thermal the most. But can make it out of any
material within reason.
