If you go to Home Depot they have pamphlets that show you how to install. I also called Dow to get their information on installation. I've also talked to two people that use 2"X24"X8" white styrofoam, nailed strapping to the foundation and friction fit the foam. The result was alittle bit of a wavy wall, but for them it "is only a basement". For wiring, you just use pancake boxes and cut groves in the foam to run the wire.
