This link came from Fine Homebuilding. It shows proper technique for flashing/sealing windows. The principles hold true for SIPs and/or alternative superinsulated wall systems. There are also some other videos that are pertinent to energy efficient construction (I dislike the term "green building).
This also gives some alternatives to SIPs. From experience building the system shown and building with SIPs I can most assuredly say that building with SIPs is MUCH more simple and FASTER! And for approx equal cost.
