window air?

the roof is blazing hot. Im guessing unless I use that refeltix metal insulation then an airconditioner might just be a joke?

My thoughts were to wall off the back room and put the air conditioner there and refeltix the roof and then put some nice wood slats over that.

Here are a couple discussions on painting the roof. You can reflect the sun's rays away with paint. It won't be real insulation, though. You'll still loose all that A/C cold air through conduction. If you're really concerned about keeping the bus cool you should remove the awful stock insulation (if it exists in the first place) and fully insulate the bus.

I honestly don't think reflectix (it's the foil bubble wrap stuff, no?) in a confined space would do anything worthwhile. It, like white paint, can reflect the sun.. Maybe even provide a slight R-value, but you'd be better off using real insulation.

For what it's worth; I just painted the roof of my bus and man what a difference! While on top painting in my socks the roof was super hot, especially the rivets, after just one coat of white paint the roof was cool to the touch. After the 2nd coat you could tell the difference inside. Insulation is my next project. I'll be using 1.5" of the foam board in the walls and ceiling.

Yup. This is why Fl buses have white roofs. At least the ones around here do.

I used the metal refelctix in my attic and it appeared to work.
What happens is the asphalt heats up. It stores the heat all day and night and radiates into the space. Like living with a bunch of toasters on all day.

Well its thin and that and some insulation.

What kind of insulation?
