  • Orlando - January 12, 2011

    STYROFOAM™ Brand Insulation ProductsORLANDO, Fla. – January 12, 2011 – Dow Building Solutions has announced that its next-generation STYROFOAM™ Brand Extruded Polystyrene (XPS) Foam Insulation products of 1.5 inches thick or greater now have an unprecedented 50-year thermal limited warranty. 

    "The extraordinary properties of our proprietary, next-generation STYROFOAM XPS Insulation formulation enable us to maintain prior physical attributes while increasing long-term, sustainable R-value retention," said Dale Winger, residential marketing manager, Dow Building Solutions. "The 50-year thermal limited warranty is a strong message to builders and homeowners that we stand behind a product designed to maintain high insulation performance throughout the life of the structure. This is particularly important as changes in consumer expectations and government policy raise the performance requirements, especially in below grade applications. Dow Building Solutions is proud to provide a broad portfolio of products to help builders meet and exceed the new demands of the marketplace and homeowners attain the next level of indoor comfort and energy savings."

    After more than 60 years of proven performance in the field, Dow's next-generation STYROFOAM XPS Brand Insulation is produced without formaldehyde, and the new foaming agents contain no volatile organic compounds (VOC), HCFCs, CFCs, and have an ozone depletion potential (ODP) of zero. The new formulation has passed fire, industry-standard physical property, and application testing for both above-grade and below-grade applications. Building code qualifications are complete, and a U.S. ICC Evaluation Service Report ICC-ESR 2142 has been received.

    The warranty stipulates that STYROFOAM XPS Brand Insulation products of 1.5 inches thick or greater manufactured after November 1, 2010, will retain 90 percent of its R-value over a 50-year period from the date of manufacture. In addition, STYROFOAM™ Brand Extruded Polystyrene (XPS) Foam Insulation products of one to 1.5 inches thick now have a 30-year thermal limited warranty, which is double the previous 15-year warranty.
