EIFS
Exterior Insulation and Finish System, a multi-layered synthetic stucco system providing insulation and a smooth finish.
Why It Matters for Homeowners
Why it matters: EIFS looks like stucco but performs differently. Older barrier EIFS (pre-2000) had documented moisture problems because there was no drainage path behind the foam; modern drainage EIFS solves this with a built-in air gap. If you are buying or remodeling a California home with EIFS, the question worth asking is whether the system is barrier or drainage style and roughly when it was installed. EIFS is also the most common path for adding insulation to an existing stucco wall.
