IMO it needs to be close to your body. In the hammock with you or between your dual layer. It needs to reflect your body heat to keep you warm so if your body is not touching it I don't see how it could do much good. I have always used it this way with success. And I have only used it below 35°.
I use it as a sit pad (doubled) and below my legs. I've used a whole roll of this stuff in my RV when winter camping -- it goes in every window. Makes a HUGE difference.
If you're looking for less than a whole roll, AHE had it, and I found it at my local RV store. They sold it 4' wide by the foot...
Great stuff. I also use a scrap as a knee pad when cutting fabric laying on the tile floor.

AHE is 16" by the foot.

If you know anyone that has the Deep Jungle and able to use their bubble Pad as a template the sizing is perfect for the Asm Hennesy Hamock.
i use to use this stuff too...
i found my old pad in the basement a few months back when i was digging around i made one with wings and i glued fleece to the one side ..
it worked good for what it was but its bulky and if your a warm sleeper you might have some condensation problems
It puts the Underquilt on it's hammock ... It does this whenever it gets cold
New hanger here. This past summer I used reflectix (4' long, cut about as wide as my hips) in the space between layers in my WBBB. I put it under a sleeping bag (40*f) I had in there, so it was (in order of me to outside under me) body, clothes, inner floor, sleeping bag, reflectix sheet, outer floor, open air, no doors on tarp. I was ok down to about 55*f in some gusting overnight air. I guess I'm a cold sleeper
I found there was condensation on the underside of the sleeping bag (the side touching the reflectix) the whole length of the reflectix sheet. This coming summer I plan on hacking this sheet up into 3rds to allow gaps, like Jsaults was saying. I'm hoping (like he is) that this will allow for adequate moisture exodus.
Trick with this stuff, based on what I've read, is that it works best with an air gap between it and the space its trying to insulate. Basically its a literal mirror -- heat in the form of infrared light gets reflected back at the heat source, but what that really means is that its heating up the space between the body (in our case) and the side of the reflectix that's facing your body. So you have to have some kind of gap -- which unfortunately leads to a tendency for moisture accumulation in whatever that thing is. Since you can't trust physics to make this space for you even in a double-floor hammock, you've got to add something, and whatever it is has to have pockets of air in it, and unless its more ccf or other type of bubble-stuff, that means it'll get soggy if its operating efficiently (more moisture released = more heat released too ) In the same way, the larger the space between you and it, the more work it has to do to heat up that airspace, so the less efficient it is there too. One last bit about durability, the more tarnished the shiny metallic surface, the poorer the material -- so the more worn it gets the less it will perform. Having said that, I think its fairly sturdy for this use, since you're not sliding it around on high-friction surfaces, and mine rolls up fairly nice with a cord tie. I'm not a hiker (not yet at least... my first and last hike was the Franconian Notch Loop in one day, so I have no appetite left for any other 'hills' ) but I see this being useable for a while with my rate of about once every other weekend or so hangin'.
So I think allowing gaps by using multiple sheets of this stuff would be useful. If multiple sheets don't work, I'll cut holes! How many gaps or holes before it becomes ineffective at radiating heat back to you is a question for someone that knows the math of this stuff and doesn't just read about it online The stuff can be very rewarding I think pound-for-effect if you find that happy medium between gaps, distance between it and your body, and what you use to create that air gap between you and it.
I hope the details I provided are a useful account of my experiences with this material. I like it, and will continue to use it until I find something better for the cost and size-for-effectiveness.
Luck!

I realize this is an older thread, but the subject is right up the line of something I was considering.
I've got an HH Explorer Deluxe, and the HHSS.
I was wondering if making a pad out of this and placing it in the HHSS in the same space you would the space blanket (above the OCF pad, below the hammock) would work?
Quieter? Better insulation/lower temps possible?
Thoughts?
I like the idea of using something quieter/more effective/more reusable than a space blanket. Pack space isn't a major issue.
Any reason why this wouldn't work, or would be a bad idea?
