ideas for insulating garage/wall ceiling covering

I am insulating my whole shop with mineral wool. I am very happy with it. The stuff is fireproof, water resistant, and will not mold if it does get wet. I have the first 8ft of wall done already and about half of the 8-12ft section of the walls done. Nothing on the trusses yet and you can walk in the shop after its closed up all day and no joke it is 15-20 degrees cooler inside. My walls are on 16inch centers and the stuff fits tight. No staples and no paper. I did go all the way around the shop with great stuff foam spray between the metal and the bottom wall plates. I am using osb on the interior walls. Highly recommend the wool.
