Traditional Yurt: felt inside or outside drip edge?

[calcetines]

Yeah sure. Ok so I bought the yurt from a spanish company so I have to translate some words:
First layer Cotton inner fabric
Second layer 3cm felt

Third layer Esterre 60 - HPV (the black stuff). On the order it's called "membrana extra impermeable y transpirable" which translates as "extra waterproof and breathable membrane."
Fourth layer A plasticy looking white fabric which is called "membrana impermeable anti-uva" on the invoice, I thought uva was either a typo or meant as much as anti UV
Fifth layer is a thick outside canopy

Wondering if the 3rd & 4rd layer is commonly used......What is a actually a common layer structure? Inner fabric, felt and outer canopy and more???

Mmmmh - why is an "extra waterproof" layer needed, below other (4th & 5th....) layers?

Exactly that was/is confusing me on your layer regime.....

"Common" is depending on location and time (summer/winter) of usage.

Insulation

can help to keep the Yurt warm, but with the right material (e.g. aluminum reflectors....) you can keep the summer heat outside too.

Yes - change "felt" to "insulation" and I can agree....
