EIFS Problems


A Cut Above Exteriors: EIFS Problems

EIFS, short for Exterior Insulation and Finish System, is an insulating and protective finish applied on exterior walls. Though often called “synthetic stucco”, EIFS is very different from traditional hard-coat stucco. The system consists of three types of layers:

  • Insulation board – attached mechanically or with adhesives to the wall sheathing; usually made of polystyrene foam or a similar material
  • Synthetic base coat – applied on top of the insulation board; reinforced with fiberglass mesh
  • Finish coat(s) – applied on top of the base coat; gives the system a durable, crack-resistant finish that resembles traditional stucco

This type of system offers several advantages, such as superior energy efficiency, great design flexibility, and reduced air infiltration; however, EIFS has its share of downsides.

The Root of the Problem

Most problems with EIFS are a result of moisture getting into or behind the insulation board, which acts like a sponge and traps water against your plywood sheathing. If enough moisture is trapped, you could end up saddled with thousands of dollars’ worth of dry rot and structural damage.

Because the successful installation of these systems is so highly dependent on keeping water out, manufacturers set meticulous specifications for EIFS applications. But even these standards aren’t enough to prevent EIFS failure. Reasons include:

  • Lack of a secondary weather barrier in most EIFS applications
  • Lack of external visual clues to early leakage problems
  • Lack of inspection and enforcement of standards
  • Lack of ongoing applicator training
  • Lack of maintenance

EIFS susceptibility to moisture issues can make even small problems escalate quickly, especially in the Pacific Northwest’s humid, rainy climate.
