I think EPS boards can provide similar efficiency at much lower thickness. Currently re-insulating the space above a bedroom and we're going for 300mm of mineral wool. Job made much harder by whoever demolished the original roof as they decided it was a good idea to leave all the rubble between the joists and put the fibreglass insulation on top. Now we're half way through dragging all the rubble out of a hole in the wall small enough that you have to slide through on your belly.
Don’t envy you that job. Been there. Had to do that for my grandparents when they had a new roof. The rubble left behind was horrendous.
Over 100kg of rubble removed, loads of dust to hoover up then finally we can lay the insulation tomorrow. Found a full box of old matches underneath the insulation and electric cables for lighting directly in contact with rubble...no fire risk there huh.
Finished laying the attic floor today. My hand are covered in glue! Managed to get most of it out of my hair though

The board in the middle is just covering our loft hatch. So no one falls through. That would be inconvenient
. All the messy lumpy stuff is just the glue. It’s very like expanding foam but different. It will all scrape off smooth ones we’ve got a roof on.
A 'roof' over your head at last, looks like good progress.
Looking really good....very exciting
Loft with a hatch, what a luxury
Looking good, should be toasty with all that insulation.
Found out why there was so much rubble in between the joists in the loft I've just re-insulated...apparently something called 'torching' which was a layer of lime mortar on the inside of the old slate roof. Very kind of the roofers to let it drop between the joists and damage the lath and plaster ceiling.
Its looking more house like
You seem to be fairly cracking on with the build now.
The build will grind to a holt soon. Unfortunately the manitou isn’t available for the next 2 - 3 weeks. We need that for getting the roof panels in place.
