I emailed our manufacturer (Shelter Designs) about retro fitting some of the canvas windows with real windows. They currently don't have a solution, but may be working on one soon. We are going to attempt to retrofit the kitchen window this summer on our own. As cold as this winter has been, I don't want to go another 7 month stretch with only the door and
as a light source. (I also want to be able to open a window and vent!)
My plan is to use the snow legs as stubs, and frame out the window to be the same size as the canvas window that is already there. We will cut the lattice and snow legs where they need to be, and fasten them to the window frame. (I'll build the frame extra heavy duty to support the lattice and snow legs.) Then we will custom order a window the same size as the opening, and fit it in there (similar to the video above).
The only thing I still need to figure out is how I will make sure the seal on the outside is good. I don't want any rain water to get on the inside of the yurt wall. The video doesn't show any caulking or any kind of seal there, so I'm not sure how water running down the outside of the yurt is deflected away from running inside the wall fabric. I'm sure I can come up with something though.
Not having more hard window openings is our only real regret. If I had to do it over again, I would have all the windows be hard openings! (Our yurt is raised 5' off the ground, so currently, I have to get a ladder out to open the windows... or close them when it rains. Also, this winter has been the coldest on record, and having the canvas windows in
mode for 6+ months really sucks!
