hammock with silver lining

[scarfell]

I want to make myself a new hammock, and i was wondering if anyone had ever put reflective materials in them (like silver emergency heat blankets)

I usually carry a foam mat to lie on, but its a bulky thing to carry around, so i'm thinking of using 2 layers of canvas (one heavy duty, top one light), with a silver lining inbetween

:..but i have no idea how those silver blankets might stand up to being rolled up repeatedly and slept on (by a wriggly sleeper lol), replacing it every year wouldnt be a big deal, although i'd rather not (for environmental reasons)

Any thoughts?

Never done out but I would have thought you would wake up damp due to condensation

Not exactly the same but I have used cheap spray on adhesive to stick cheap emergency silver foil blankets to cheap builders tarps....all from the £ shop and have been very pleasantly surprised how well they have lasted and how effective they have been. How well one would work sandwiched inside a hammock I have no idea but for a total of £3 it's must be worth a try.

Ive used a windscreen frost protector as insulation in my hammock before. It was fairly warm for the weight but condensation was a real issue. It would be the same for space blankets I would think.

I've made a few reflective underquilt protectors like that but not the hammock body itself. I can't say I felt much difference hung as an UQP, hard to determine especially given that they were either low breathability or non breathable so needed lots of venting to avoid condensation. They worked brilliantly if used a fire heat reflector/cooking tarp with a sort of secondary purpose of reflecting body heat as an UQP.

Found some reflective material, going to make myself a down stuffed under quilt and a thin reflective mat, i might try a silver emergency blanket aswell but wont sew it into the lining

Decided on 4oz ripstop nylon instead of canvas, will use a fire retarding spray.. not a fan of plastic really, but found a good deal and thought its worth a shot

Might post a build diary up if anyones interested, my old hammock was a simple (traditional) straight one, but this one will include asymmetric ties and will be extra long

Not sure how well that work without an airspace. You want to lie directly on it?

Also, you're going to get a lot of condensation.

If you are laying directly on it like that, would reflection not turn into convection?

 

[scarfell]

no the original idea was to use canvas, and then on top of that is the sleeping bag of course

 

[sunndog]

It would still be tight against you though wouldn't it?

You say your ccf is bulky...how about a -5*c down underquilt that packs to the size of a grapefruit?. a little bit Spendy at £165 but deffo the way to go for packsize, weight, and comfort

 

[scarfell]

The sleeping bag creates an insulating layer of air, so you arent pressed against it (even though its squashed)

165 for the sake of saving a little room is defintly not my idea of a good solution lol besides this is all about DIY

The squashed insulation loses almost all it's insulative value though. That's the reason you need a groundpad .

I've tried putting a silver foil blanket in a hammock, under a layer of insulation. I didn't get a condensation problem, but it was like sleeping in a crisp packet at the slightest movement.

The sleeping bag will add very very little bottom insulation dude

D.i.y you say, aha.....how bout this for £15

Silver "Thermal blankets (sheets)" are very overrated! In their adverts, they claim to reflect x% of the body's heat, but they only reflect radiant heat and the body gives off very little of that! The RAF Mountain Rescue did a test of these things many years ago and found that an ordinary plastics bivvy bag was more efficient than a reflective sheet
