Here's an unusual one. Tent rental firm, they have a 45' high bay with BA Fans and floor heat and a couple Unit heaters. They hoist them with wires and spread them out. Separate high piled rack storage outside this area, so fuel load is just what is hanging. Fire resistant canvass primarily, plus the fun of the window panels being a non expanded plastic. Any ideas?
