DuPont™ Styrofoam™ Brand Square Edge XPS Insulation
Water-Resistant Insulation for Attics, Foundations, Conventional Roofs and Crawl Spaces<br>U.S. HFC Regulation Compliant Formulation
<br><b>DuPont™ Styrofoam™ Brand Square Edge Extruded Polystyrene (XPS) Insulation</b> is a grey, extruded polystyrene foam (XPS) insulation board that provides continuous insulation over steel stud or wood framing, in masonry unit cavity walls, conventional roofs and meets the needs of the commercial foundation and building floor slab needs. It can also be used for attics, foundations/slabs and crawl spaces in residential applications.<br><br>With more than 60 years of proven performance in wet environments, the closed-cell structure of <b>Styrofoam™ Brand Square Edge XPS Insulation</b> resists water pickup, enabling it to retain a high R-value over time – a necessary property in wet, below-grade commercial foundation and commercial roofing applications.<br><br><b>Styrofoam™ Brand Square Edge XPS Insulation</b> is classified as a Type IV product when tested in accordance with ASTM C578 and provides a long term insulating performance of R-5 per inch.

Features & Benefits
Ease of Installation
- Easy to handle, cut using a utility knife or serrated blade, and install.
- Comes in a wide selection of sizes and thicknesses.
- Designed to help ensure energy efficiency and minimize on-site cutting and waste.
- Provides a secondary barrier against groundwater leakage.
- Helps protect foundation damp proofing and waterproofing, especially during backfilling.
- Minimizes the freeze-thaw cycling of the foundation, reducing the potential for cracking.
- Warms the foundation, reducing the potential for condensation.
- Will not corrode, rot or support mold growth.
High Performance Durability
- Provides a weather resistant barrier to enhance the building’s resistance to air and moisture penetration.
- Resistant to degradation from soil components and will retain insulating performance characteristics after prolonged exposure to moisture.
- Has a minimum compressive strength of 25 psi and a flexural strength of 50 psi.
- Can be used in a number of applications like sheathing, foundation walls, masonry cavity walls, and more.

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.
