EIFS-Exterior Insulation and Finish Systems

Exterior Insulation and Finish Systems (EIFS) are multi-layered exterior wall systems that are used on both commercial buildings and homes. They provide superior energy efficiency and offer much greater design flexibility than other cladding products.

EIFS typically consist of the following components:

  • insulation board, made of polystyrene or polyisocyanurate foam, which is secured to the exterior wall surface with a specially formulated adhesive and/or mechanical attachment
  • a durable, water-resistant base coat, which is applied on top of the insulation and reinforced with fiber glass mesh for added strength
  • an attractive and durable finish coat - typically using acrylic co-polymer technology - which is both colorfast and crack-resistant.
