Generated explanation

The illustration shows a cutaway of a synthetic stucco exterior insulation and finish system (EIFS). Expanded polystyrene foam insulation is fastened or adhered to wall sheathing, identified as plywood, OSB, or gypsum board. A fastener and washer are shown recessed into the foam insulation. Glass fiber reinforcing mesh is embedded in a base coat labeled 1/16 to 1/4 inch thick, with a textured finish coat forming the exterior surface. The peeled-back layers illustrate the assembly sequence rather than damage or a defect.
