Traditional Yurt: felt inside or outside drip edge?

[calcetines]

Hi guys, thanks for the extended library of info. I have been reading a lot on the forum the past weeks, a lot of good insights.
We're about to raise our traditional yurt, from inside out consisting of:
Lattice
Thin inner canvas (not really 'canvas'. a thin fabric)
Felt
Breatable membrane
Outer canvas


I've build a deck and will install a drip edge today. Would you place the felt outside over the drip edge so the lattice pressures directly against the drip edge? Or would you tuck the felt between the drp edge and the lattices?

 

[Jafo]

I would place the felt outside, definitely. If you can leave a gap between the floor of the deck, so it will not sit in the water, even better.

 

[calcetines]

Ok that's clear! Thanks for replying. What makes you say definitely?

The second part I don't fully understand.....you mean raising the vilt a bit above the floor? My deck is a circle so there is no floor beyond the drip edge. Wait I'll add a picture

 

[Jafo]

Oh, you should be good then as far as clearing the ground. What usually is done, is that a skirt of bended plywood is put around the edge of the platform and the lattice bumps up against it. It keeps the lattice from sliding off. You wouldn't want the felt between the lattice and the skirt. I hope these images make that clearer. Notice how you cannot see the bottom of the lattice in the second photo? It is because the skirt is raised up about an inch above the level of the floor.

calcetines my deck is like yours. Overhang, no skirt. For photos, copy and paste on google images:

Mine is the rough looking canvas yurt with green door and rafters either side. Several detail photos including ell that held wall lath to deck. No insulation. I simply draped the cover over the platform edge to keep water out. In summer heat I hiked up the cover down low. That creates a cooling draft into the yurt that exits through the ring. Edit to say, nice photos Jafo.

"rough looking one" nice bob
I see your point, would work too. Altough I have no idea yet what the length of my outer canvas is.........I think I'm gonna measure it tomoorrow


Nice deck Jafo, I'm made a skirt like yours. You say "you wouldn't want the felt between the lattice and the skirt"........what is the reason you really wouldn't want that?

 

[calcetines]

My sticks out one inch above floor level and covers the side of the floor and the supporting beams, being 5,5 inch in total

Because then the lattice wouldn't sit tight up against the skirt. Also, if the felt will go past the top of the floor and overhang, which is a better seal than butting up against the floor itself. You can either cinch it to the deck or screw it to it, as I did with mine.

Ah ok, I understand. Second reason is interesting

 

[Bob Rowlands]

Yup, rough. Tough too. Like my wife says when I pull her close for a goodbye hug in the morning. She grabs my arms and says, "Don't ever lose those 'guns, Bob.". haha

Good luck. Have fun.

hahaha
thanks, rasising day is tomorrow (amm located in portugal)


one last one:
to tie the rope to the rings on the door/window......what knot would you use?

 

[Bob Rowlands]

Well isn't that somethin'. My wife is Portuguese. It just dawned on me, it should be dawning on you shortly. haha Get some rest. You're gonna need it.

So we made it! 24 ft yurt, three healthy men and we stopped when the first water protecting layer was on.
On the following morning we placed a UV protecting layer and the outside canopy. Now moving on to finishing jobs & bed building, my third son is due to be born begin july.


Now I know from experience how rapid yurts can be raised, this was our first time and we countered a couple of manufacturing mistakes so normally with 3 people you can get it done easily within 8-10 hours.

 

[calcetines]

This picture is not our Yurt, but here you can see the last two layers before the outside canopy.........can anyone tell me more about the qualities of these layers? Especially the black one?

I tried a google search, it's used in roofing I guess, the name is "Esterre 60 - HPV".......the seller brands it as breathable, non-permeable cover.......do you guys have something similiar?

The white one is sold as UV protecting, I guess to protect the mentioned black cover

 

[Bob Rowlands]

Making good progress. Get some stairs built and walk right in. Beats me what that '60' stuff is.

 

[TSRalex]

....
first water protecting layer
....
UV protecting layer
....
outside canopy.
.....

I´m a little bit confused on your layer system - can you explain it more detailed and describe the used material of each layer?

 

[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???

Mongolian trad yurts the layers are white liner, then felt, then cover. The first layer keeps the interior bright, and probably clean. My guess is felt picks up all manner of litter when off the yurtwhile being moved. Just a guess.

 

[TSRalex]

First layer: Cotton inner fabric

OK - the decoration layer....

Second layer: 3cm felt

OK - the insulation layer....

Third layer: sterre 60 - HPV (the black stuff). On the order it's called "membrana extra impermeable y transpirable" which translates as "extra waterproof and breathable membrane."

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

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

Mmmmh - why is an "anti UV" layer needed, below an other (5th) layer?

Fifth layer is a thick outside canopy

OK

Wondering if the 3rd & 4rd layer is commonly used......

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

What is a actually a common layer structure

"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.

What is a actually a common layer structure? Inner fabric, felt and outer canopy and more???

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

 

[calcetines]

allright, thanks for the replies. I'll go find out some more about that esterre HPV stuff
