Insulation on ceiling

Is the being insulation in newer buses (mineís a 2004 short bus) better than in older large school buses? Has anyone just left it in and left the original metal roof undisturbed?
I was thinking of doing that or taking it out and putting XPS in the ceiling

I like the metal roofs. I wasn't going to take mine down when I bought a bus. But the bus I bought had perforated ceiling that I didn't like. And speakers in each panel. So I took mine down and decided to insulate with XPS.

I guess the XPS will be better insulation. Plenty of people leave theirs in and don't mind. More people take everything out and run spray foam. My bus is 2003 and the fiberglass was in good shape when I took it out. The walls were nasty though. I imagine yours isn't too bad unless you have a leak or something. But are you going to be in hot or cold temps? Leaving all your windows in place? Raising the roof?

All those answers will lead to a better decision that works for you.

Would like to be in both hot and cold temps. I don’t want temp to dictate where I can go. No roof raise. Keeping all windows and emergency hatch.

I wanted to leave my metal roof intact, but after taking my wiring guards down, I found a few roof leaks. Very glad that I removed all the ceiling metal. It will also give better access for when I mount the PV panels to the roof.

I left my ceiling intact, and have seen a number of buses with them still intact. Windows are a big loss of heat. If you are going to push the extremes you will want all the insulation you can get. Read the "Arctic family bus"

It really put my fear of driving into New Jersey in the rain in perspective.

2009 6-window... to remove insulation?

Hi all, jumping back on this thread as it seems the most applicable. I've recently decided to replace my metal ceiling with t&g, and naturally with other roof work to be done (vent fan, solar) I'm removing the metal panels. My bus is a 2009, the insulation looks pretty good--I'm all about doing something less toxic and am considering replacing this insulation with Havelock Wool (not here to be talked out of wool, all things considered), but it seems like it's not necessarily more "environmentally friendly" to pull the fiberglass stuff out and replace it if it still looks good?

Sort of looking to be talked into removing this insulation and start with the Havelock stuff, but be honest

Also one from the wall, I want to say the black is dirt given how much came off on my hands from the metal panel on the back wall, but if it looks like mold to anyone, say so!
