Tips for Success with Exterior Insulation and Finish Systems

摘要

Exterior insulation and finish systems are wall cladding assemblies that combine rigid insulation board with a water-resistant exterior coating. Unlike traditional stucco, which is composed of inorganic cement-bonded sand and water, EIFS uses organic polymeric finishes reinforced with glass mesh. As an energy-efficient, economical wall covering, EIFS can be effective for both new construction and recladding applications. However, successful use of EIFS is highly dependent on proper design and sound construction practices. Without correct design and detailing, these wall systems have been known to fail dramatically.
