Zep, I’m not a scientist and didn’t play one on TV,
but lemme see if I am interpreting your results correctly.
Basically, you built a 6 sided box with one side of the box removable. You inserted several different insulating materials in that side, one at a time, and tested them against heat loss in cold weather. Is that about right?
The charts seem to show that the Prodex product is just a bit more efficient than the Homey D foil, which is just slightly more efficient than the pink stuff insulation. Is that about right?
Is there any real reason to believe that these materials will act radically differently in warm weather than cold? Not trying to dissuade you from running the warm weather tests, just thinking out loud.
BTW, I find it amazing that you still have an XT machine still functioning. That’s gotta be some kinda longevity record all by itself.
