Additional Information

Typically, an EIFS system includes insulation board that is secured to the exterior wall surface with a specially formulated adhesive, a water-resistant base coat that is applied on top of the insulation, and a finish coat. EIFS gained attention from the insurance industry when claims began to arise alleging damages caused by moisture getting trapped behind them leading to mold and wood rot. The second and later generations of these systems have eliminated or reduced some of the risks, but many insurers continue to attach EIFS exclusions to contractors' liability policies, especially those that work directly with EIFS.
