Made for use in exterior cavity wall and foundation applications, Styrofoam™ Brand Scoreboard Insulation combines exceptional compressive strength with high moisture resistance.
Styrofoam™ Brand Scoreboard Extruded Polystyrene Foam Insulation* is an extruded polystyrene foam insulation board that is scored longitudinally on 16” and 24” centers, making it easy to size to commonly used widths, cut and install. It has excellent insulating characteristics, high resistance to water and water vapor, exceptional compressive strength and long-term durability.
* Styrofoam™ Brand Scoreboard Insulation is a former product of The Dow Chemical Company

1 R means resistance to heat flow. The higher the R-value, the greater the insulating power.
2 Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam™ Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation.
3 Based on 1” thickness.
