An Exterior Insulation Finish System (EIFS) is an insulated decorative finish system applied to the exterior walls of the home. Another term for this is synthetic stucco. On an exterior wall, we typically have 2x4 or 2x6 studs for framing. The sheathing (substrate) on the exterior side of the framing is typically plywood, OSB board, or something of that nature. Insulation board made of polystyrene (or similar material) is secured to the exterior wall surface by way of mechanical fasteners or adhesives.
