I have the WBBB 1.7 dbl
has anyone tried reflectix as a mid liner ?
I have used reflectix as a pad to supplement my UQ in the deep cold. It works really well, and you don't really feel like you have a pad under you. It conforms well to your body.
Like shug, i have a small peice of reflectix for my legs where my uq doesnt cover.. It works amazingly well, and as stated above, it feels nothing like a pad. Though it is a little loud, it might help to keep any hungry animals from getting too close!
The only down side of reflectix is that it is a vapor barrier. If you have it right up against you watch out for moisture. Something in between to breathe a bit helps. I use it with my WBBB under my feet as I don't have a full length UQ, works great.
It seems like it would fit nicely in between the layers of the double layered RidgeRunner. One could use the 48 inch wide piece and custom shape it to the contour of the Ridgy.
I do have an underquilt...I wonder if there would be a way (or a benefit) to attach below an underquilt...
The other day I tried to find something like reflectix on this side of the pond, but drew a blank. What is the insulating matter? I need to go to a baumarkt and explain to them what I'm looking for I think...
B&Q have rolls of it on sale in the uk. It's essentially just bubble wrap with aluminium foil on each side.
ebay.com seems to be where it's at. Actually found some at only 8 bucks shipping, but it comes in rolls of 4 inches width - seems a bit narrow, no?
When looking for insulating wraps on German ebay the other day, I got pipe insulations about a decimeter thick with rock wool. Seemed slightly exaggerated somehow..
It's not *just* a vapor barrier it's a radiant heat barrier. In physics there are three majorly studied methods of heat transfer Convection, Conduction, and Radiation. Dead air space and insulation help in Convection and Conduction exclusively. As each of these three methods are generally approximately equal in rate of heat transfer adding a reflective surface in your arsenal could increase your comfort level significantly. As a radiant heat barrier it is possible that one of those survival blankets or some reflectix on the underside of your tarp might even have a significant effect (you would be reflecting all the heat radiating off your body back down towards yourself).
I cut a nice 6' peice for Gobsh last night and he used it in his DL WBBB, and he loved it. He said it was better than his therma-rest mat.
Not so sure about reflectix under UQ. I use it for footbox coverage and sit pad mostly.
Seems radiant heat would be caught by UQ before reaching Reflectix much less before being bounced back.
Who knows, no physics scholar here.
Insulation is primarily there to stop conductive and convective heat transfer. The material will actually re-radiate the heat out and you still end up losing the heat. The reflectix actually reflects that radiation back towards the source which we all know is where we want it in the winter. If your UQ stays warmer you stay warmer.
When they said it acts as a vapor barrier, she meant that it won't breathe. Meaning and moisture/vapor that comes off you through the night, will pass through the quilts. Now if they're is a waterproof layer beneath the quilt, the moisture will get trapped in the down, instead of evaporating away,slowly loosing it's warmth. More of a concern the colder it gets.
