While you are looking Heirony, could you be sure to find those figures in Metric units. I am just getting more and more used to that way of doing things,
.
BTUs per cubic meter of dog turds (does that make it DTUs? (Dog Turd Units)) just sounds so much more official.
As for felt layers and thickness, travelling, I never saw any felt on a yurt in Mongolia that I would guess to be as thin as a inch, most was more than an inch but I would guess less than but close to 1 3/8". I didn't have my calipers. They also seemed to have at least 2 layers on the roofs that I saw, and it just hung down on the sides, so I am guessing the walls were 2 layers also since they were not separate pieces, the roof and wall, at least not when I noticed.
It was all sort of a charcoal, dark grey color felt, and that was the yurt material. When I really looked, they just had a light polyester or muslin on the inside and what looked to maybe be a nylon cover that was white that they put over the outside. I am guessing to make it not so dark inside and to make it look prettier on the outside. When it rained this outer cover was not waterproof, it soaked through. We were rained on a lot while we travelled there, but the roofs didn't leak through.
I am not saying they all did things this way, it is just what I noticed in the places where we stayed. We had 2 nights in a touristy place, the rest of the time we just rolled up to a friendly looking yurt and our translators asked if they had space. Usually they would move to one another family member's yurt and gave the 4 of us the yurt. They liked having the cash.
One night we could not find space, so we slept in our own tents. Luckily that night it didn't rain. When it rains it is a cold driving rain, and I sure got used to sleeping near a wood-stove on a fairly comfortable couch in a warm dry sleeping bag. Not quite glamping, but...
