I’m constructing a building for my aux. generator as I’ve previously discussed here. I’ve laid up the CMU walls and am now at the point for the roof. Am considering using some welded steel for the trussframe structure but not sure what to use as sheathing? Reason being I want it fireproof.
I know they make flame retardant plywood but any other good options? I thought of a metal roof but wouldn’t that require some means of sheathing underneath? Span is not a big problem as the building dimensions are only 6′ x 6′.
As always, any thoughts or ideas are appreciated!
