Exterior Insulation Finish Systems (EIFS)
EIFS Stucco Systems
An EIFS system, or Exterior Insulation and Finish System, does not rely on a hard base coat but instead on thinner layers of modified materials. EIFS provides continuous insulation, allowing for a wide range of design flexibility and offering a highly energy efficient option. Compared to hard coat stucco systems, EIFS generally provides both insulation properties and durable water barriers.
A typical EIFS process consists of the following:
- A waterproofing application is applied over an exterior sheathing before the insulation board
- The insulation board, made of polystyrene or polyisocyanurate (ISO) foam, is secured to the exterior wall with special adhesive installed vertical ribbons to create an effective rainscreen system.
- A water-resistant base coat is applied on top of the insulation. This is then reinforced with fibreglass mesh to fortify coat strength
- A stucco finish is applied on top of the water-resistant base coat, resulting in an attractive, consistent finish
