EIFS
Stands for Exterior Insulation and Finish Systems. The product is also called synthetic stucco, and refers to a multi-layered exterior finish that's been used in European construction since shortly after World War II, when contractors found it to be a good repair choice for buildings damaged during the war. The majority of repairs to European buildings were to structures constructed of stone, concrete, brick, or other similar, durable materials.
There are three layers to EIFS
Inner Layer Foam insulation board that's secured to the exterior wall surface, often with adhesive.
Middle Layer A polymer and cement base coat that's applied to the top of the insulation, then reinforced with glass fiber mesh.
Exterior Layer A textured finish coat.
Maintaining EIFS
- Any opening, such as door and window frames and the areas around flashings, must be sealed to prevent water from seeping behind the EIFS.
- Gutters should be kept clean and positioned to drain away from the house.
- Foam should not extend below grade.
- Items that penetrate the stucco must be sealed.
