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 make 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.
