S-13916 is an all-in-one structural panel that combines oriented strand board (OSB) with a built-in layer of rigid polyisocyanurate foam insulation. It is designed to provide structural bracing, a water-resistive barrier, and an air barrier, all while adding thermal resistance (R-value) to the building envelope. This "R-3" version is the thinnest in the R-sheathing lineup, designed to meet energy codes without significantly increasing wall thickness.
