Styrofoam? Brand Scoreboard
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

1Not all product sizes are available in all regions. R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft??h?¡ã¹ó/Btu. R-value determined by ASTM C518.
2Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam? Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation. For static loads, 3:1 is suggested. For dynamic loads, 10:1 is suggested.
3Based on 1¡± (25 mm) thickness.
4These numerical flame spread and smoke developed ratings are not intended to reflect hazards presented by this or any other material under actual fire conditions.
