1Vertical 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.
