These are the only three I know of doing the polyiso foam core panel in significant quanitites. None of them consider themselves SIPs but IMPs (Insulated Metal Panels) however there is structural data for the panels that can be used to engineer a structure as strong as any other metal SIP. You just won't get any support out of the manufacturer.
I recently finished the shell for my house out of Kingspan panels. I set all my connections and supports so that the structure could handle 140+ mph winds. I also sealed all my joints, took structure orientation, sun angles, overhangs, and wind patterns into account so that I can make the house zero energy. |
