Special Advertising Section Why XPS Is Simply Better Not All Rigid Insulation Not every rigid insulation board is built the same. Differences in the manufac- turing processes create dramatically different board structures and perfor- mance. Compare the leading options: Board Is Created Equal: Weigh The Options Before You Buy FOAMULAR® codes and green building mandates, is highly versatile, extremely moisture resistant, and offers outstanding energy efficiency. Saving Energy By Preventing Energy Loss FOAMULAR® XPS insulation provides the highest level of defense against energy loss in residential and commercial applications. In fact, FOAMULAR® XPS is guaranteed to maintain 90% of the advertised R-value for 20 years.* Many other types of foam insulation cite high R-values; however, many of these claims are inflated when performance over the life of the foam is calculated. The Best Choice For Above-Grade Sheathing FOAMULAR® XPS insulation creates a protective thermal envelope around the entire building perimeter, reducing energy loss due to thermal bridging through wood or metal framing or steel fasteners. Using FOAMULAR® ASHRAE 90.1** and contributes to achieving LEED® EPS ISO XPS XPS satisfies energy codes like credits. XPS by Owens Corning meets the requirements of changing building (shown, bottom left):A collection of thermoplastic beads pressed together under heat and pressure. EPS has air spaces between its beads, allowing water and air to penetrate, lowering its R-value. (shown, bottom center):A thermoset plastic manufactured in a lamination process using liquid that expands between facing materials. These facing materials may de-laminate and cause installation and durability problems. Its cell structure is irregular and more open, resulting in higher water absorption and lowering its R-value. (shown, bottom right):A durable, thermoplastic polystyrene board with a homogenous cross section, resulting in very low water absorption, deliver- ing long-term thermal performance. XPS lacks individual beads like EPS that can fall apart and is not brittle, nor dependent upon facers like ISO.
