You may have seen my recent post wherein i mentioned that part of my reflective cuben tarp got ripped at one of the tie out areas.
I could shave the tarp down on the side that go ripped, re add more tie outs, and continue to use it in that fashion or as a liner as i planned to more so, but i was also thinking of the following, and welcome feedback.
Reflective VBL. As Jerry and others have said, for IR reflective material to fully work, it needs some air space on both sides of the material, so that the heat doesn't get conducted through a material touching it (and maybe other reasons as well?).
So i thought of gluing strips of 1/8 inch evazote foam on the front and back of the reflective cuben, to create some air space between my body/quilt and the reflective cuben. Since the cuben is a bit stiff of a material to begin with, i probably could get away with using less strips on the side that will be facing my body, but since a quilt would tend to sink in, probably would have to use more foam strips on the side that the quilt will be facing/touching.
I'm not too worried about conduction via the foam since the foam is a very low thermally conductive material to begin with–the interesting thing is that besides creating some IR reflective areas, i will also be creating pockets of insulating air as well. Downside to the idea will be some bulk, as foam is bulky. For the strips, i would probably punch out some small circular holes in same.
While i think that VBL clothes make a lot more sense in a lot of ways, i would use this as a double VBL for my wife and i, allowing us to combine our heat underneath a quilt.
Anyways, what kind of adhesive would work well for both the foam and the mylar? Any thoughts, comments, or what not otherwise?
