For our sub floor we are using rigid foam insulation in between the trailer beams. We added the first layer last week in one day, tarped it up and then came back the next day to find that the tarps failed us and rain got on, and under, the insulation. So I spent a lot of time drying out the panels we cut, as well as drying out the trailer. The day it happened it was really hard to keep my cool! I was so frustrated that our tarps failed, and that we are so dependent on the weather since we are building outside.
We also realized that in our composting toilet, the fan we ordered was the wrong one! So dealing with the Richard to return just the fan and replace it with the correct, solar friendly, model was required. He did a great job helping us out and we really appreciate how he worked with us to correct our mistake! We also had some trouble with our time lapse camera because I didn't read the manual :P
There have also been some great ups this week though! We got the trailer leveled, our sink was delivered, and we set dates for the framing of the walls!
After the insulation dried out, I reinstalled it. Bought a bigger tarp that covers the entire trailer (before I had layered two tarps... in hindsight it was a terrible idea). Bought bungee cords to tie down the tarp instead of duct tape (again... was a terrible idea).
Today Ben and I also installed the second layer of insulation, filled in the gaps with spray foam insulation and added the first piece of wood to the trailer! We add 2x6 treated lumber on the outskirts of the trailer so that when we are building the walls, we nail the wall both into the trailer steel and to the wood on the outskirts for double the connection.
It was a big milestone for us! We have been mainly doing the leg work like research, calling people, and ordering things online so it is a great feeling to actually be progressing in the real build. Building it ourselves is also a blessing because we are able to see the entire project progress. It is also a challenge though because there have been a lot of random problems that we've had to solve.
For example, the trailer tail lights were too close to the edge of the trailer for us to be able to fit a 2x6 flush to it. We had to turn the lights upside down and re-screw them in place! Also today it randomly started sprinkling so we had to quickly cover the tarp in the middle of cutting insulation!
We also had a nice visit from Amy Scott Jack and Henry (my uncle aunt and cousins) at the build site today!
I finally figured out my time lapse camera to! It is super awesome, can leave it in one spot and it can take pictures for hours!
Here is the first video from today! In this one we are re-fitting the dried insulation and then laying out the cuts that we made for the second layer
And here is the second one from today :) This one we are cutting the panels the right length, filling in gaps with spray foam, finishing second layer and adding the wood skirt on the back of the trailer. You can see that I took a nice break laying on the insulation and staring at the sky today :P
