Neat Sheet, Microfoam, Underquilt???

[utilisateur]

Oh i think this is what i meant in the Insultex thread.
Glad to have a name shorter than "white foamed PE stuff that looks like footfall sound isolation /

[the stuff they use] for underlayment for the interlocking hardwood floors

Guess i need to try that too now

EDIT:
Being able to read helps .. ****

As this is LD PP i think its not the same as the footfall sound isolation (hd? PE)
So this is probably the soft and pliable packing stuff like the sheet they put between screen and keyboard on a laptop like Finn related to and the more rigid stuff for footfall insulation or sometimes used for packing too is PE

wow i couldnt imagine d* mn could be *ped

I have a roll of Laminate floor underlay which i am going to try out.

Maybe make a sandwich with aluminum type foil stuff?!?

Dirt cheap and plenty of it! light too!

Make sure to post results when you do it. I have been tempted to pick some up at Home Depot, but haven't had the chance to do it yet. I think it will work . . . .

I've been using that stuff for a while now. As mentioned, the heat return isn't that great - but I still have high hopes for it. I've not tried it as an underquilt, only as a pad.

I've sandwiched it between ripstop, double layers between ripstop, and even added a layer of space blanket between two layers of it with fleece on top, ripstop on bottom. That last one works pretty good, but needs more insulation for cold temps.

Because it's so thin I assume it compresses too much using it as a pad. Perhaps as an underquilt will do the trick. I'll give it a whirl.

Even though it's so thin, because it's CCF it doesn't pack crazy small, but still smaller than some other options.

I made a 3/4 length underquilt with John Deere-hood microfoam sandwiched between the two layers of a cut-down neatsheet. I made it after a pretty cold night and might have gone overboard, but I used three sheets of foam. I think they're something like 18x36. I arranged them so they would overlap under my lower back and butt, with two sheets side-by-side under my torso and the other extending to mid-thigh in the center. The result is toasty with lows in the 50s; when I first get it I can feel the heat radiating back to me. The result is also unbearably bulky and only moderately light. I'm sure it could fold better if I just used one layer of foam. Since it is totally encased by the Neat Sheet, you could roll this and stow it on the top of your pack - it would shed water. I like the neat sheet without the foam for warmer temps. The NS/3-layer foam system is a workable poor man's mid-range UQ, but it's confined to car camping for me. Buy the family size NS and experiment to your heart's content - it's big enough to make numerous quilt cuts.

P.S. - I used a seam ripper on the NS baffles. It took about two minutes.

Interesting. Thanks for the info. Maybe this idea isn't as promising as I thought . . . .

[vitamaltz]

No, I think it's a good idea! I do a lot of car camping, and I'm happy to have this in my kit. I might have overstated the "moderately light" thing too. I currently have it tied rather than clipped to my bridge, and the two weighed in this morning at 22.2 oz, with bug netting removed. Furthermore, it's rigid enough that if you wanted to slip a real CCF pad in between the UQ and the hammock, it would hold it very snugly.

I do think it might be slightly different stuff than footfall insulation because the little foam cells flatten or pop if the foam is compressed too much and I imagine you wouldn't want that as a floor underlayment. Think of bubble wrap, but on a tiny scale and in a random pattern.

[vitamaltz]

I measured the UQ all by itself - 8 oz.

[turkeyboy]

That's pretty light. Maybe I'll have to give it a try.
