Exterior Insulation Finish System, commonly referred to as "EIFS". EIFS is an elaborate wall "system" combining the use of EPS insulating foam board and acrylic polymers into a plaster wall, creating a system that adds insulating "R-value" to the wall and at the same time offering vibrant color choices, creative use of shapes and enrichments, and unlimited design potential. The system can be offered installed on site or as a prefabricated panel system. Special effect to imitate brick, stone, and marble are additional benefits both of exterior and interio use.
