EIFS - Exterior Insulation and Finishing Systems
What are EIFS?
Exterior Insulation and Finish Systems (EIFS) are multi-layered
exterior wall systems that are used on both commercial buildings and
homes. EIFS were introduced in the U.S. almost 30 years ago and were
first used on commercial buildings and then later on homes. EIFS
typically consist of an insulation board made of polystyrene foam
(which is secured to the exterior wall surface with an adhesive
and/or mechanical attachments), a water-resistant base coat applied
on top of the insulation and reinforced with fiberglass mesh, and a
finish coat typically using acrylic co-polymer technology. This type
of system is often referred to as artificial stucco.
The Potential Problem with EIFS...
The potential problem with EIFS is that moisture can get trapped
behind the highly water resistant material with no way out. This can
cause the framing to rot and foster the growth of mold between the
exterior and interior walls. Damp and rotting wood is also a prime
target for subterranean termites. It should be stated that the
potential for these conditions exist with any type of exterior
siding product be it brick veneer, wood, or vinyl siding. The
potential for this condition with EIFS however can be exacerbated by
its superior water resistance. Once moisture gets in, regardless of
its origin, it usually has no escape.
The main locations where water tends to infiltrate into the framing
structure of a building using an EIFS is around doors and windows,
where the roof connects to the EIFS (roof flashing), and below
extended exterior deck connections. Also, any moisture from within
the home trying to find a path out will likely be thwarted by the
EIFS.
The EIFS industry has been plagued by class action, and individual
lawsuits (particularly in humid climates). The public's confidence
in the products have been shaken to say the least. The lawsuits
contend that the problem is with the nature of the product and the
manufacturers contend that sloppy installation and poor maintenance
are the culprits.
Regardless of who is "right", its clear that homes with EIFS require
special scrutiny during inspection.
