the first wofati greenhouse design

I learned some interesting technique from Bob in this video. Maybe I can locate a source for glazing track like they are using here.

Since the surface is sloped, having something that could withstand a hail storm seems prudent. What about a polycarbonate panel like this? You could butt them up to each other so the open end cells overlap, a little silicone to bind and seal them, and they should be light enough to only need support at the top and bottom and the ends so no shading. Otherwise if glass is the only option, perhaps some shower doors would work? A T channel between them like this could support the glass, and a gasket on each side of the glass could thicken it up to seal it. A channel for both inside and outside that overlap/touch, then the glass and gasket would fit into the gaps if that makes sense? Shower door glass shouldn't have any UV coating.

Edit: the first link also has this channel for connecting them together for a 1 stop shop option.

Paul is very keen on glass. It's more in line with his values.  

I was originally interested in polycarbonate. The main downside is the loss of light transmission over time. Polycarbonate would be significantly cheaper, have a higher R value, and be much easier and faster to install. It would even have light transmission comparable to glass for the first two years. After that it drops off fairly quickly as the material degrades.

Glass it is, and double or triple paned it must be.

There are a couple suppliers of this extruded aluminum glazing system known as PRO-SEAL. I'm currently studying this design guide that they provide

Have you already checked sites like Freecycle and the Missoula Habitat for Humanity ReStore? Always a chance they might get some windows or shower doors, perhaps they would take your number in case something came in?

We want to avoid any coatings on the glass. It is difficult for us to determine if salvaged glass is coated or not. For the sake of removing variables in the experiment, we will be using new glass.

Josiah posted some more great update pictures in his bootcamp thread. Here's some hightlights!

Kyle's been making some EPIC stone stairs for the wofati greenhouse. Jen Tuuli took this awesome picture:



And here's a nice close up from Kyle's thread:

a video update

Lots of cool wofati greenhouse pictures recently!

Jennifer took some nice pictures of deck framing over the cold sink (Check out her thread for more pictures!)


And also some nice sketches of the greywater system in the greenhouse (more in her thread)


And Kyle's got some great pictures of the greenhouse, too, like:



He's also been working on door framing, trying to mesh roundwood door framing with a dimensional door. He'd love some input on the door making over in his thread:

Greetings permies.com:
I live in Ottawa, Ontario, Canada; which is about the same latitude as Montana; and will likely not move far as the Grandkids are here.
I have supported 2 of Paul Wheaton's Kick Starters; The Truly Passive Greenhouse  and SKIP.
I have also been reading some of the 'dailyish' posts and links that I receive.
I am not the most computer savvy person around so I likely have missed a fair amount of information and usually have not been available for the ZOOM sessions.
I enjoy the 'movies' on the greenhouse and hope there will be some summarizing information.
Examples could include but not be limited to cross sectional drawings of the structure with dimensions and materials, efforts and resources expended versus benefit and so on.
The current question I have is about the 'COB' on the 'back' wall; Does it continue up over the roof at all? How is the roof insulated?

I originally sent the above text to a different thread and Paul suggested I ask my questions here.

To Summarize: Are there current cross sectional drawings of the Wofati Structure with dimensions and materials? That would possibly include the answer to my question about 'COB'.
My 'effort and resource expended versus benefit' question will be better answered over time.

Sincerely
Jerry Beattie

Lots of cool stuff happening at the wofati greenhouse! The window frame is installed, and natural insulation is being applied. I love that they're using cob, straw and wool for insulation! I found a bunch of great pictures in the various Boot's threads. There's even more in their threads, so make sure to check them out!

more framing for the window!

the awesome stone stairs

Jen's Bootcamp Experience

the wool and straw are put behind the lattice work for insulation

and then they are cobbed over!

Kyle's also been doing a lot of work on the greenhouse door and latch. There's lot of pictures on jos Bootcamp thread--here's just some of them!

most of the latch pieces

the door jam is coming along

I really like this one, as it looks kind of like a before/after picture, with one just the wool insulation, and the other the cobbing over.

half is cobbed, half shows the wool insulation

Kyle's gotten more work done on the door!

the latch bolt slides easily

Jennifer shared pictures of the cobbing of the walls, too. They've begun putting on the nicer, second coat of cob!

second layer of cob is so much smoother!

More greenhouse updates! Jen Tuuli got this nice picture of the greenhouse. I love seeing how far along it's come!

look at all the nice cob!

Kyle is doing some really cool work on making a wooden door latch. His woodworking is way over my head, but it looks so cool! Be sure to check out his thread for more pictures.



Josiah posted about how Matt figured out how to fold aluminum sheet to make a corner flashing cap

where it goes!

Lot's of cool updates today! Josiah made an awesome video show-casing all the new work they've done (the latch, the cobbing, the bathtubs and windows and more!)!




[ur=https://permies.com/t/120/157417/permaculture-projects/Kyle-Permie-Bootcamp-BRK#1264908l]Kyle[/url]'s posted lots of pictures of the door latch!

here's one of the pictures of the door--check out his thread for more!

And look at the glorious cob work picture that Jennifer posted!

Ooooh, the siding is going up! Check out this picture from Josiah's Bootcamp thread:

Kyle has done amazing work on the door! Here's one of the pictures from his Bootcamp thread



And Josiah posted this great picture of Kyle and his door

I just love these series of pictures that Kyle posted, that I can't resist putting them side-by-side (visit his thread to see them larger!)

ready for the handle!

Kyle's been hard at work on the door, and posted a ton of detailed pictures on his thread. Here's just one picture:

door handle about to get shaped!

Jen got some great pictures of the door, too, and she posted them for her 100th BRK post! WOOT WOOT!

the outside of the door, with Kyle!

She also snapped a picture of the outside of the greenhouse!
