Exterior Insulation and Finish System (EIFS) are a type of cladding system integrated in to exterior walls, providing insulation and waterproofing; and attached adhesively, mechanically or both to the substrate.

EIFS typically consists of the following components:

  • An optional water-resistive barrier (WRB) that covers the substrate
  • A drainage plane between the WRB and the insulation board is most commonly achieved with vertical ribbons of adhesive applied over the WRB
  • Insulation board typically made of expanded polystyrene (EPS) which is secured with an adhesive or mechanically to the substrate
  • Glass-fiber reinforcing mesh embedded in the base coat
  • A water-resistant base coat applied on top of insulation to serve as a weather barrier
  • A finish coat typically uses colorfast and crack-resistant acrylic co-polymer technology
