Roof Extension for Door
Roof Extension over Door
I also extended the roof for the door, in order to protect the door from rain and extend its usage this way - it's covered with PE.
The supporting timber will be fixated on the first step in front of the door. I'm also thinking to use some PE to cover one side (west) where most rain & wind comes from.
Detail: The top outer rain cover rope is reaching over the extension, holding down the roof rain over - once it's raining I will see how the water flows and may make further detail adjustments.
Door Frame Extension
Finally also I made a "classic" wider door frame, to cover up the junction where thermal insulation and rain cover approaches the door frame.

Thermal Setup (Roof/Wall Junction Detail) of Winter 2007/2008
The difference between winter 2006/2007 and winter 2007/2008 setup is a layer of bubblewrap (two layers: bubble and foam) for the roof; and this makes a noticeable difference.
I primarly used this additional layer for dust prevention (avoiding dust from the straw segments falling on the cotton interior cover, which let's dust fall through all into the yurt, as last year when that bubblewrap layer was torn apart while putting it up by the wind, this time the taped bubblewrap we were able to put up), secondary the layer also functions as moisture blocker, so no interior moisture reaches the straw insulation.
It's 6°C outside, inside 14°C without stove around 21:00, I fired the stove for 30 mins with little wood, and I reached 19.1°C and now that the stove warmed for 1 hour, the temperature stays at 19.0°C after an hour - very good. Next morning 9:00 still 12°C - apprx. 0.7°C drop per hour. The door frame isn't yet insulated and has 1-2cm gaps, once those gaps are sealed the insulation will be even better.
I also tied the yurt again, tried to clean the ropes with little success, this time with hot water and a bit soap, some moss went off, but I assume to clean the ropes they would require to be soaked 12 to 24 hours really, not sure putting them into laundry would do it. After all ties were attached, finally the attached room I was able to put up again.
As first experience, the attached room is suitable as very temporary setup, but otherwise it's a bit a hassle when once is work on the yurt itself, for everything the attached room needs to be detached which implies partially disassembled. Anyway, once getting a new place with more space to use I will put up a regular 2nd yurt, the 4m diameter one I made.

Preliminary rain cover tied
In order to prepare more roof weight, I used a strong additional band to support the main rope (waved through top junctions of the lattice wall, and responsible for the static of the yurt).
Finally the roof got thermal insulation, using the straw filled blankets with jute - this time I put them alternate on the roof in order to keep the crown-wheel in balance and not tilt as the last year. Since I left 1/4 with multiple layers of bubble-wrap again to have daylight also enter on the south side, there is weight missing, yet, this time the crown-wheel is still in position, a good sign.
I made a bubble-wrap layer as moisture stopper for the straw insulation, it's tied with a separate rope close to the wall rain cover.
As next I put up the roof segments, a friend helped with this part who briefly came by, but this part is also doable as single person.
Finally I put the roof rain cover and tied it temporary - tomorrow I will tie the yurt more exact, and try to clean off the moss of the ropes.

Today I made the decision to stay for the winter time at the current place after the farmer agreed to extend the time, even though I spent time reviewing other spots, but none was really suitable or available right away. I keep looking for a place for springtime, when I definitely have and want to move.
Two things I did today, replacing the door and putting up the termal insulation of the wall I made last year.
Replacing the Door
Finally I replaced the old door, which I just realized, had a tilted frame due the uneven ground, which finally was sufficient so the door was off 1.5cm, too much.
The new door is more beautiful as I used higher quality wood and no gaps between the lath as they are interlocked with each other.
Replacing door: Putting new door aside (1 of 9)
I used following procedure to replace the door without taking down the entire yurt:
- put the new door in front of old door
- untie & move main rope (between khana junctions and responsible for main static) off the old door, the same moment the outer rope for the rain cover maintains static integrity
- tie main rope again, keep it moveable, e.g. move from old to new door
- untie all other ropes from old door, and tie on new door
- remove old door
- move new door in position
This all can be done by one person, point 2 & 3 are most important.
Replacing door: Two ropes, main rope and rain cover rope (2 of 9)
Replacing door: main rope untied, main static done via rain cover rope (3 of 9)
Replacing door: tieing ropes to new door, new door opened (5 of 9)
Replacing door: tieing side-junctions to new door frame (6 of 9)
Replacing door: tieing side-junction to new door frame, detail (7 of 9)
Replacing door: new door completely tied on lattice-wall/khana (8 of 9)
Putting up Thermal Insulation of the Wall
What's usually a rather easy task was this time more complicate, since the attached room was using some of the outer ropes to attach itself.
So I first assumed I had to remove the entire attached room first, and then add the insulation and then erect the attached room once again - but then I realized I only had to remove one side of the room in order to have access to the rain cover of the wall, and keep the shape of the attached room and didn't have to move anything I store there.
The thermal insulation I made last year, jute with open straw and the whole thing quilted, 5 pieces - and I hang them all on flexible PVC binders which one uses to bind plants on sticks. After 2-3 hours the blankets were put up, and bound on the main rope, which on this new addtional weight got very tight.
Again I let 1/5 of the entire circumference with 4 or 5 layers bubblewrap so some daylight can enter the wall, this on south side of the yurt, all the rest with the straw-based insulation.
Finally I put the wall rain cover back again, as well the attached room, but not yet fully with all ropes as the after tomorrow a friend visits me to assist me to put the thermal insulation on the roof, when I require again to untie some ropes again.
I also took the chance to clean the rain cover with cold water and a lobe, mostly stain like a bit moss where the ropes went along.
The PE ropes I tried to wash in a small container with hot water, some moss went off, but the ropes remained with green moss on it - maybe I need to soak them longer and maybe with a bit of soap, let's try tomorrow this.

It's still above 0°C during the day, 4-8°C and working outside gives warm quickly. We have high fog covering up the sky, so almost no sunheat is able to heat up the yurt and remains the same temperature like outside. That's also why I decided to put up the thermal insulation so heating with the stove is more effective.
I just returned from a trip visiting friends of mine through Switzerland, which I made with my recumbent.
Last Thursday, 17th October, the weather changed dramatically, from the "Golden October" (15-18°C) and sunny days, to chilly winds and temperatures from 2-8°C, and where I was even below 0°C with kind of first snow (called "graupel", kind of condensed snowflake).
When I arrived in the yurt this afternoon, around 14:00, it was 3.7°C - and even thought it was slightly warmer inside than outside - even my LCD screen refused to start up at that temperature. So I heated the stove, to reach 13°C after 1.5 hours - and this still with summer setup (without thermal insulation).
The attached room had some ice on the roof, so it reached well below 0°C the last days - and time to insulate the yurt now as I decided the first frost is the time to put up the winter setup with straw-based insulation again.
|Panorama Sunset of October 15, 2007
Sunset of 14th October, 2007
The last days have been sunny, 10°C in the morning inside the yurt, in the afternoon 28°C (with closed skylight, open door), outside 17°C peak.
I have been working further on enhancing the door with a extended roof over the door, and extension of the left and right frame parts to cover the junction of rain cover to the door (some photos follow later).
The last days I spent reviewing alternative places and connected with like-minded and like-spirited people.
A few places I visited was in a remote and less populated area of Switzerland, the Napf region:
At one location on this trip was also a yurt, made by Thomas:
6.5m diameter, heavy cotton rain cover with a 2nd light cotton cover over it, 1.70m diameter acryl skylight, and 2m high walls, lattice wall made of fir laths, the roof poles apprx. 3cm thick bamboo, and stove pipe through the roof.
A few days ago I also finished two yurt doors by adding some simple locking mechanism with a handle, and add some layer styrofoam as insulation. I have to replace my current door because the door as shifted the last time when I "fixed" it and now requires another adjustment, and take this opportunity to replace with this unused, speak "new", door.
September Equinox I spent visiting Damanhur.it , a spiritual ecological community, for two days, and traveled with friends near Turino over Grand St. Bernard pass:
A few photos from one of the "nucleo" at Damanhur:
The bridge of old egyptian mystery school and alternative sustainable energy is shown in the photos quite well, the labyrinths are made for walking meditation and next to it some photovoltaic modules.
Upon return from the trip, the weather changed and cooled off, with rain temperature down to 10°C, and inside the yurt 12°C - this afternoon the sun briefly comes through the overcast sky and warms up the yurt to 20°C.
Within the next days I will put up the straw insulation I made last year, as soon there are a dry sunny day to remove rain cover and so forth.
Evening of 20th September 2007
Day started with 4°C, climbing to 14°C at noon, and afternoon 30°C inside the yurt, with closed skylight and open door, outside 4°C in the morning to 17°C in the afternoon.
The topic of storing heat from the day to the night arises again, for days like this that would be very suitable to have.
I'm also thinking putting up the winter insulation to ease the temperature drop after sunset.
This sunset was wonderful, soft gold light from the sun - some slight fog in the far distance softening the atmosphere.
Today I just fixed the skylight again, the clear tape I used to seal the junction of the cone-like form of the PVC I used.
It usually lasts for 5-6 months before the tape glue is dried and looses any adhesion - a quick look in my diary here shows it lasted now over 10 months. The PVC isn't as soft as it used to be, a bit rough handling and it cracks, might be time to replace it again.
Again a couple of days of mild temperatures, 18-22°C outside, and up to 30°C inside when I keep the skylight and door closed, with door open it goes down to 24°C inside.
While looking for alternative locations for my yurt I made contact with more tipi and yurt-enthusiasts. Yet, Switzerland is kind of small country with about 7,500,000 residents, and once you get to know a dozen of people with this kind of interest you quickly realize somehow they all know or at least heard of each other one way or another.
