A update in January 2000 was
distributed addressing the requirements for
each of the model building codes as it pertains
to barrier and drainage EIFS. Some changes have
taken place since the last update; therefore,
listed below are the current requirements.
BOCA- The 1999
National Building Code has been published and
requires the following:
EIFS with or without a secondary
weather resistant barrier.
* Special inspectors are
required on all types of construction except
when the EIFS is installed over masonry or
* It is important to note that the
local code official has the authority to
disregard this requirement if he/she
* All details that are a part
of our detail package must be tested to show
that they are designed to prevent water
penetration. To date we have not conducted
tests since EIMA is working with BOCA to
finalize the test procedure.
* BOCA has extended all
Barrier EIFS evaluation reports for 1 year
without justification of details as noted
Special inspectors are not
required for EIFS with drainage.
* A weather resistive barrier
of No. 15 felt or equivalent shall be installed
over all sheathing substrates.
* A means of drainage must be
created between the insulation board and the
weather resistive barrier except when concrete
or masonry substrates exist.
* All penetrations and
termination's must be flashed to maintain
ICBO - The Acceptance Criteria for
External Insulation and Finish Systems AC24
dated November 1999 requires the following:
EIFS with or without a weather
* Barrier type systems are
limited to types I through IV construction.
Barrier systems are not allowed to be installed
in type V construction (i.e. combustible
* Special inspections are
* Required on all Type V
construction (i.e. combustible construction).
EIMA submitted revised acceptance criteria to
ICBO that would limit drainage to Type V, Group
R, Division 1 and 3 construction. This was
voted on and accepted at a meeting in Whittier,
CA on October 15, 1999 and is now in the AC24
Criteria dated November 1999.
SBCCI - There are no specific
requirement's or limitations for Barrier
Systems or EIFS with drainage. It is strictly a
ICC - A final draft was voted upon
during the week of September 13, 1999 in St.
Louis. The draft is similar to the
requirement's of BOCA's 1999 code. It was
published in March, 2000 and is now available
from ICBO, BOCA or SBCCI. It is now up to the
individual states to adopt or not.
IRC - The IRC will replace the CABO
One & Two Family Dwelling Code. It went
into effect in January, 2000 and requires the
* EIFS with drainage over a
weather resistive barrier.
* Special Inspections will not
