October 2016 Part 1/2 Wall insulation

I began insulating the walls in October, I was soo happy to begin this project.

The Layers

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

0-look-at-that-window

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.

    I lost your email address, did a search on the email, but still couldn’t find it. I put in a bulkhead behind the drivers seat. Then covered it with fence boards. This is a fiberglass bodies shuttle bus, tomorrow I plan to put reflectix on outer wall on one side, then put 1″ foam insulation with using as standoffs, then glue (construction adhesive the foam insulation, this will give what ever the thickness of the standoffs which is wood lath which are mounted length wise screwed to the interior plywood. Then screw the fence boards thru everything.
    This results that altho the reflectix is stuck to the outer fiberglass wall there will be aprox .25″ air gap, then foam insulation and then fence boards. I find the hardest thing is figuring out what to do, doing it is the easy part. The alternative is to get luxery vinyl plank flooring and use it for the wall, but I already have the new blhd covered with fence boards, am concerned to get too many different materials on the interior, but that peel and stick flooring will stick to the foam real good. The new flooring that is installed is dark, so concerned about getting too much dark in there.

    I spend alot of time thinking, I could do this, but then I should do that first, then if I do this first, then when I get to that, it is a pain in the ass and I wish I would have waited, if you live in Washington State I am about 15 min south of Brermerton and get to south King County every week.

      Hey Jim,

      I just got your message, I just sent you an email to your email address ending in e@gmail.com. I’m not sure what exactly you’re asking, but I totally understand your struggle. It’s very hard to have direction and to decide on what to do next, as well as how to go about it. I spend a few days every month, just staring into my bus. Brainstorming solutions/plans. If you wanna send me a picture of your setup I can give you my two cents. I used a lot of 2×4’s/scrap wood to maintain pressure against things that needed to be held in place, I hold the 2×4’s in place by wedging my feet, shoes or whatever else I have laying around.. Sometimes I strapped things down with very narrow shallow screws and scrap wood just to keep something in place. That way I can reuse the holes with deeper thicker screws.
