Several points are available for “advanced framing” or "optimum value engineering" practices, including 1 point for spacing studs at greater than 16 inches on center and 1/2 point each for spacing ceiling joists, floor joists, and/or roof rafters at greater than 16 inches on center. Closed-cell Spray Polyurethane Foam, because its use in framing cavities increases the racking strength, can support the adoption of these material-efficient framing measures. Note that the involvement of a knowlegdable structural engineer to capitalize on this opportunity is recommended.
