I began insulating the walls in October, I was soo happy to begin this project.
Here’s how it’s all gone down. I got the first layer of insulation in the bus. What you see here is a 1 inch of polyiso with a reflectix radiant barrier between the insulation and the outer metal. I intend to put another inch in after doing some framing and running some logistics. I believe it’s best to have a 1/8~3/4 airgap to make the reflectix insulation effective, however I did not do that. I purchased 100 feet of the reflectix on a whim so I figured I should use it. It’s pretty fun and satisfying to work with.
A Drunken Collaboration
Notice the bright bus window in the back right corner of the bus. I found a 3 day stretch without rain and impulsively got drunk and took this out around this time. I was aware of my actions, but it put a lot of pressure on me when I woke up and remembered what I did. I am glad I did it, but what a silly decision. The welds on the top strip are terrible, I don’t want to talk about it..
I’ll get back to the insulation project later, it will be my first live update. Very exciting!
Just Go Pro Spray Foam
Oh yeah also worth noting to anyone doing this project, just go with 2 part spray foam insulation. I am estimating my insulation costs to be about $1,000. I have been working on this for a few weeks now, but if I went with spray foam it would’ve been done in a day for not much more than my insulation cost. It also would provide structural stability and it would be “closed cell” which means that no moisture passes through it.
