Everything you ever needed to know about EIFS Stucco & Waterproofing.
"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.
EIFS in North America
North American builders began using EIFS in the 1980's, first in commercial buildings, then applying it as an exterior finish to residences--mostly wood frame houses--using the same techniques that had been successful in Europe.
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.
EIFS layers bond to form a covering that doesn't breathe. That's fine when no moisture is present behind the cladding, but if moisture seeps in it can become trapped behind the layers. With no place to go, constant exposure to moisture will lead to rot in wood and other vulnerable materials within the home."
