Styrofoam™ Brand Scoreboard

Commercial | Residential | Multifamily | Wall

Get long-term durability with stable R-values

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

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 ft²•h•°F/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.
