Exterior Insulation and Finish System (E.I.F.S.)

E.I.F.S., or exterior insulation and finish system, is a method of multi-layered cladding for exterior walls. E.I.F.S. offers insulation, protection from water damage, and a clean, finished surface for building exteriors. At Soumar Masonry Restoration in Chicago, IL, we use E.I.F.S. in commercial and industrial restoration to improve properties’ structural stability, strength, beauty, and lifespan. E.I.F.S. can improve the comfort and energy efficiency of the property as well as provide a decorative, finished coating that protects the exterior walls from damage.

What Is Exterior Insulation and Finish System (E.I.F.S.)?

An exterior insulation and finish system uses insulation boards covered with a plaster or stucco coating to protect exterior walls from the elements, water damage, and wear and tear. Installing E.I.F.S. components can improve a building’s energy efficiency and longevity by reinforcing and insulating it. The E.I.F.S. method was developed in Germany in the 1960s and brought to the United States in 1969. Since then, it has evolved and been adapted to meet modern building methods and materials.

Advantages of E.I.F.S. Exterior Finish System

E.I.F.S. is a cost-effective, sustainable solution to exterior damage, wear and tear, and exposure issues that could affect a building’s lifespan, energy efficiency, and structural stability. The biggest advantages of E.I.F.S. installation are:

  • Enhanced Insulation –I.F.S. has incredible insulating abilities and reduces thermal loads on exterior walls.
  • Reduced Air Infiltration – I.F.S. can reduce air infiltration by up to 55%.
  • Highly Versatile –I.F.S. materials are lightweight and can be sculpted into different shapes and patterns to enhance building aesthetics. Finish coats are available in a wide variety of colors and textures.
  • Protection From Water Damage and Moisture –I.F.S. offers exterior waterproofing and protection from moisture infiltration and migration. When properly installed, the system can reduce the risk of moisture intrusion, water damage, and mold and mildew growth.
  • Durability – I.F.S. materials are durable and resistant to impact and weather damage. They are formulated with an acrylic binder, which makes them resistant to fading, chalking, and discoloration.
  • Low-Maintenance – While E.I.F.S. does require regular maintenance to prevent water intrusion, it is more low-maintenance than other exterior finishing systems. Repairs are simple and cost-effective, and the material is resistant to cracks and damage.

Key Components of E.I.F.S. Installation

The key components of an E.I.F.S. are a water-resistant barrier, drainage plane, insulation board, reinforcing mesh, water-resistant base coat, and a durable finish coat. There are a few different methods of E.I.F.S. installation:

  • Polymer-Based System—The PB system uses a 1/16 inch thick base coat applied to insulation before the finish coat. The insulation consists of closed expanded polystyrene (EPS) attached to the sheathing with adhesive or mechanical methods.
  • Polymer Modified System – The PM system uses a 3/16 inch to ½ inch thick base coat applied to insulation before the finish coat. This insulation consists of extruded expanded polystyrene (XPS) that is mechanically attached.

Design Options for E.I.F.S.

The two basic types of E.I.F.S. are a barrier wall system and a wall drainage system:

  • Barrier Wall System – A barrier wall system uses a base coat portion of exterior skin to repel water and reduce the risk of water penetration and damage. All components are fully sealed and flashed.
  • Wall Drainage System—A wall drainage system uses a weather barrier installed behind the insulation, which serves as a secondary drainage plane. This barrier is fully flashed.

Energy Efficiency & Sustainability of E.I.F.S. Insulation

E.I.F.S. insulation is highly energy-efficient and sustainable. The enhanced insulation provided by E.I.F.S. can reduce heat and cold transfer into buildings and heat and cold loss from heating and cooling systems. Buildings with E.I.F.S. can stay more comfortable year-round and reduce reliance on heating and cooling systems, resulting in a lower carbon footprint and decreased energy costs.

Maintenance & Care of E.I.F.S. Materials

E.I.F.S. is very resistant to mold and mildew but can accumulate dirt, dust, and debris over time. Cleaning and maintaining an exterior insulation finishing system can extend its lifespan, maintain its appearance, and reduce the risk of degradation and damage requiring facade repairs. E.I.F.S. exteriors should be cleaned every one to three years. They should only be cleaned with low-pressure or soft power washing and non-abrasive cleaners. E.I.F.S. exteriors do not need regular painting, but if minor cracks or damage appear, they should be repaired right away. You should regularly inspect exteriors for cracks, chips, spalls, or other damage that might need caulking and repair.

E.I.F.S. vs. Traditional Cladding Systems

Research conducted by the United States Department of Energy has concluded that E.I.F.S. is the best-performing cladding when compared to brick or wood exteriors. E.I.F.S. are very resistant to water damage compared to traditional cladding systems, and they also offer enhanced insulation, making them more eco-friendly and energy-efficient. E.I.F.S. also have improved fire resistance and sound absorption, making it an ideal system for multi-unit dwellings and commercial properties.
