DuPont™ Styrofoam™ Brand Ag Board XPS Insulation

U.S. HFC Regulation Compliant Formulation

<br /><b>DuPont™ Styrofoam™ Brand Ag Board Extruded Polystyrene (XPS) Insulation</b> is durable XPS foam board that resists moisture infiltration, withstands high-pressure cleaning and reduces the potential for moisture condensation within the wall. <p> In addition to its exceptional insulating value, <b>Styrofoam™ Brand Ag Board XPS Insulation</b> resists moisture infiltration, withstands high-pressure cleaning and reduces the potential for moisture condensation within the wall. The easy-to-install <b>Styrofoam™ Brand Ag Board XPS Insulation</b> uses shiplapped edges to create a secure joint that does not require taping, saving considerable installation time.</p>

1Values are consistent with the criteria of ASTM C578 and the requirements of the FTC R-value rule (16 CFR Part 460). R means resistance to heat flow. The higher the R-value, the greater the insulating power.

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.

3Based on 1” thickness.
