i have alot of experience to share with rockwool if any one wants to know the insulation value verses others and the fire resistive values.
to keep it short ask if you want to pursue this road.

I'm very interested to hear what you know. I haven't made any insulation decisions yet and I'm curious about rockwool. I'm planning on 3" of insulation most of the way around, so rockwool would work for that thickness.

If you say so.
Medium thickness steel wool will catch fire with an ordinary match.
Just sayin'...

The video clearly shows them hitting it with a torch and it doesn't ignite or burn, and is cool to the touch on the other side of 2". I use that Rockwool in my powder ovens and have nothing bad to say about it, other than it is a bit pricier than other insulations.

Indirect vs direct flame. Not to mention compaction percentage.
Otherwise, I'm afraid I'd have to inspect your needlework.

For those of you who have insulated between the roof ribs with rigid foam, and subsequently added through-roof features down the road (more vents, skylights, holes for solar power cables, etc.), you are likely to have decent insight on it's mechanical performance.
1) Have you noticed any issues with the foam staying put?
2) How much time and miles had passed since initial install?
3)What adhesives or methods did you use to keep the foam from shifting or settling?
4) Did you fill the cavities entirely, or provide a gap for a radiant barrier?
5) What would you do differently, given the knowledge you have about the products and methods you chose, a similar time frame to install, and 150% of the budget you spent?
6)Would rockwool solve any of your problems?

I used rock wool panels, roxul I think, 1.5”. It’s been a couple of years but very few miles and it’s still perfect. I cut holes for the toilet vent recently to m go through the roof instead of the wall (big improvement!) and for solar penetrations. I would use the stuff again for sure. It’s less toxic than regular foam board if it burns and supposedly is mold resistant. I’ve has a leak or two and haven’t had any mold so it’s been great so far. No glue, no nothing, just wedged them in to fit and put the cedar ceiling up.
Only thing I would do differently would be additional supports for the cedar ceiling because I was dumb and skipped a rib or two and it was just dumb.

Tell me everything! We just bought our first bus and are overwhelmed with information on insulation. We were leaning towards polyiso and it's high R-value, we will be in Texas most of the year. But someone mentioned rock wool and it's sound dampening properties so my interest is piqued. Thank you!
