An EIFS finish looks like traditional stucco but is formed by applying an acrylic-impregnated cement finish over fiberglass lath. A foam insulation layer on the back of the cement prevents cracking—a problem with cement- and gypsum-based stuccos. EIFS products like Dryvit (pictured) don't have a fire rating because the noncombustible material simply falls off when confronted with moderate- to high-heat flames. EIFS will not compromise the fire resistance of the wall system underneath. Dryvit
