    Physical Properties

      Method Unit Value
    Compressive Strength<sup>2</sup> ASTM D1621 psi, min. 25
    Water Absorption<sup></sup> ASTM C272 % by volume, max. 0.3
    Water Vapor Permeance<sup>3</sup> ASTM E96 perm, max 1.5
    Maximum Use Temperature<sup></sup> - °F 165
    Coefficient of Linear Thermal Expansion<sup></sup> ASTM D696 in/in•°F 3.5 x 10-5
    Flexural Strength<sup></sup> ASTM C203 psi, min. 50

    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.
