I've built housing that used single-sided and double-sided panels. The SIPs are good for walls and roof panels, but when they were stacked for delivery the inner and outer surfaces rubbed on each other. With single sided panels the interior finish is applied separately after the structure is closed to the weather.
I see the examples in
DDG Images are delivered with raw OSB on both sides.
