I was picking up some spray foam this morning and noticed that that had "stone wool" batts right next to their blown cellulose.
Hope this helps somebody.

Rock wool can be used as an insulate above block off plates, in chimneys, etc. It is a Canadian made product that is (by Canadian building code) an official fire barrier since it is made of: rocks!
Off of their website "Roxul insulation is non-combustible and withstands up to 1177°C (2150°F). It can act as a fire barrier. Combustible insulation, on the other hand, can fuel the fire and cause it to spread." I saw a home show that left a propane blow torch attempting to burn Roxul all weekend without any success.
It is sold in bags of various thickness (like fiberglass insulation).
2 years ago I installed some Roxul ComfortBAtt R14 in my basement walls on top of my spray foam. It is MUCH easier to handle than fiberglass insulation. The best way to cut it is with a serrated knife, just like you would use to cut bread. Works like a charm

Gloves, safety goggles, and a p100 respirator are needed to go into the attic. Otherwise i itch and couch for a few days.
maybe its just me.
