We are installing foam boards to insulate the Airstream for heat and sound. We found a DIY'r who recommended installing a 1" foam board and then a 0.5" foam board to boost the "r" value of the overall insulation--this affects how well the insulation prevents heat transfer into or out from the Airstream. I'm looking forward to the next post when the interior walls start to go up.
If you've lived in the Brazos Valley for at least one spring, you've probably picked up on the fact that the Brazos Valley is geologically shaped like a bowl. As the local plants wake up from their wintery slumber, they fill our bowl with their fine yellow flakes. The Route 104 Science Airstream was no exception. It looked like a giant twinkie and while I don't necessarily want to be compared to the cream filling while I'm working in it, it was time to clean it up. Fortunately, I have children that love using the pressure washer and foam cannon. While it could still use a little refresh on the polish, I'm glad to see it shining again.
