School Bus RV Conversion Chapter 5 - Insulation and Foundation

Now that the bus was stripped to the bare bones, it was time to build her back up.

After cleansing the steel with Xylene, we applied a generous coat of oil-based Rustoleum paint to serve as protective enamel. We have big plans for our bus so can’t be worrying about preventable things like rust! In case you didn’t know, our primary goal it is to live in the bus (all 300 square feet of it!) for a year or so while we build our shipping container home in the great state of Tennessee! Hey, I never said we were sane. Once our home is built, the bus will remain on the property and serve as a fully-equipped mother-in-law suite. I’m hoping it will entice our Florida family members to come visit!

 

 

We let the Rustoleum dry for 24 hours and then it was time to insulate. We went with ¾” thick residential Styrofoam, with an R-value of 4.0. The higher the R-value, the greater insulating power it has. Luckily, the walls were already insulated with mineral wool so we only had to apply this to the floor. Once the Styrofoam was installed, it was time to throw down some ½” plywood for added insulation and a base to which we would mount the top floor to.

 

To convert the round wheel humps into usable space, we squared them off. Once they were boxed in, we mounted plywood to all sides & filled them with cellulose insulation, which is primarily comprised of recycled paper pulp.
