When planning my addition, I intended to stud within the frame and use fiberglass bat insulation so I had my foundation poured to be flush with the outer face of my sills. I am now contemplating whether or not I could change my mind and use SIP's.

The frame is started so I can't modify it.

Has anyone used SIP's to enclose a frame without having a foundation overhang to sit them on? What was your method?

I don't see why I can't simply let the sip's "hang" from the mounting screws I apply them with and allow the 5-1/2" overhang around the house at the foundation line.
