Here is a little progress picture from the jobsite in Oregon. This home used our 6.5″ EPS wall SIPs(R24) and our 10-1/4″ Neopor Roof SIPs (R46). Neopor is an EPS foam product that has graphite embedded in the foam bead. The graphite helps reflect heat which produces a 20% increase in R-value. The graphite gives the foam a dark color which can be seen in this photo.
