First wall cavity insulated! We needed to put it in before we hid it behind framing.

I need to rotate the little window on the end--i don't notice it was a horizonal window, not a vertical. I'm thinking of adding a bay window/reading nook out the end while I'm at it. What do you think?

Roof Curb

I have been working on the curb for the edge of the roof. I made some mockups to figure out how the rubber would act, going over the curb. I've been trying to make a shape that will allow a drain in the curb. This is the sheet of rubber, with a curb, with a gap in it:

In the corner of the roof I put tapered pieces to help the rubber fit nicely. Here it is, after I put on foam to help blend it smooth. I'll trim off the foam:

Here is the curb, with the drain-gap, all tapered and smoothed out, and with the flashing attached:

(sorry about the bad photos, I ran out of storage, and I'm having trouble getting the latest ones from my phone).

Sealing it up

We got the house pretty sealed up. Here is FlexWrap on the wheel well. The way to put this on: fold the tape, sticky side out, (with liner still on). Lay on wheel well, in place. Start peeling off the liner at the top, only the part of the liner that is against the wheel well. Once it is stuck to the metal, peel off the rest of the liner, and unfold it up against the wall.


We also put in the door. Here we are finishing up putting nail flanges on the door. I primed it with purple pipe primer. I used a couple beads of construction adhesive, and a bead of "Through The Roof" so that it just squeezed out.


Then we finally set the door in place. This door has taken a while!

And got it fastened:


And taped:


And we finished up the sealing. There was a window that leaked where I glued on the nail flange, so I re-caulked it. And I caulked all the nail holes in the roof and walls. Zips isn't supposed to need this...but I felt it would help:


And then it SNOWED:







But our little house is nice and snug.

Doorsill

The big sliding door needed to be supported out beyond the edge of the trailer, so we put in a metal sill:


Here you can see how it hangs over the edge of the trailer. There is a piece of light-colored foam on the ground in the background, that makes it hard to see how the red part goes:


It stuck out beyond the wall, so I made a little piece to support the flashing tape. The two little flanges on the left-hand side go under the red sill, to fill the gap behind the red sill, so the tape has something to sit on:


You can't see where it goes under the lip of the red metal, but here is it installed:


I'll put down flashing tape, and then protect it from footsteps with another piece of metal. Here I am forming and installing that exposed door sill. I need it to cover the tape that steps around the metal in the corner shown above.



The flange is bent:



Have the step, just need to bend the upstanding flange by my left thumb:

One corner, neat and square:

Windows

We have been putting in windows, but not posting pictures, so here are some:
This window was designed to be vertical, but we are installing it on it's side. I think it work.


Here we are framing out the curved window:



Here we are preparing to put in a door:



Here is the north window, installed (but without flashing tape yet):



Here is the north window from the inside:

we got rain before I put on the flashing tape, and water came in. I guess caulking the flange wasn't good enough. I was always planning on using the tape, but I'm hoping that the flashing tape is just another level of safety, and isn't really needed...but I guess the caulk wasn't good enough. I'll probably try to fix the caulk, and then tape it.

Here is the door sill after I've bolted it down, and painted it.

See, the door assembly is thicker than the wall, so I want it to hang out beyond the trailer a bit, but the threshold of the sliding door needs support, if people are walking on the edge. So, I got a scrap of metal angle, and bolted it to the metal trailer frame, though the subfloor. I painted the bolts and nuts. The bolt heads will stick up out of the red sill, and into a groove in the bottom of the aluminum door frame, which will help keep it all in place.
