Exterior Insulation and Finish Systems (EIFS)

Exterior Insulation and Finish Systems (EIFS) are proprietary, multi-layered exterior wall systems that are increasingly popular with architects, building and home owners because they improve energy savings, reduce costs and provide tremendous design versatility. Solutions like DOW™ XNERGY™ rigid insulation or STYROFOAM™ Brand Panel Core Insulation are key to EIF's excellent energy efficiency, durability and moisture resistance.


DOW™ XNERGY™ Rigid Insulation or STYROFOAM™ Brand Panel Core Insulation provides a continuous layer of insulation that eliminates thermal breaks and moderates the temperature of the wall cavity, reducing the potential for dew point condensation in EIFS applications. Using Dow insulation, architects designing EIFS assemblies are provided with a single-source solution for the air and water-resistive barrier, continuous insulation and exterior wall finish with the reliability and familiarity of STYROFOAM™ Brand XPS Insulation. By reducing project requirements for concrete, structural steel and HVAC, the lightweight and energy-efficient EIFS assemblies using Dow insulation helps streamline the construction process and minimize material costs, as well as lower heating and cooling expenses. The higher density of DOW™ XNERGY™ and STYROFOAM™ Brand Panel Core enable a stronger EIFS assembly.
