Skoolie Window Capping | How to Cap Windows on a School Bus Conversion

Capping school bus windows was a big stepping stone for our skoolie conversion! We recycled the sheet metal from the ceiling and made “pans” for our skoolie window replacement.

This was much easier than using sheet metal and rivets to cover the school bus windows from the outside of the bus. Also, we personally thought it made the skoolie feel more like a home, while keeping the shape of the windows of the school bus intact.

Find out why we capped some of the school bus windows, how we capped them, what they look like now that they are all done in this article.

Skoolie Window Capping

School bus windows are drafty. Remember chugging along to school when you were a kid and the window was halfway down because it was frozen there or it just wouldn’t move? I sure do! We knew we had to cap some of the windows to keep the R value of the bus as high as possible. We ended up capping the windows in the toilet room, the fireplace area, behind the fridge, in front of the kitchen sink, our closets, & shower room.

We recycled the metal from the ceilings to use as our caps on the window. We measured the inside window dimensions to size and added an inch on to all sides. We used a malco turbo shear that goes onto your power drill to cut the thick sheet metal. Then, we marked an inch from all sides. Now, it was time to bend the sheet metal at those inch markings. Using a brake press, we were able to bend the sheet metal about 90 degrees on every side, just how we wanted it.

Then, we got silicone, a hammer, screws, & a drill. These skoolie window caps should go in tight. Silicone all four edges of the window, then plop the window cap in, and use self tapping screws to securely hold it to the window frame.

That’s it! Your skoolie window capping day is over!

What do you do with your old school bus windows? There were some windows in our skoolie that were hard to get open, so we switched a few around. Otherwise, our old school bus windows that we didn’t use are in storage in case anything happens to the windows we have now.
