1.2
SYSTEM DESCRIPTION AND REQUIREMENTS
The exterior insulation and finish system (EIFS) shall be a job-fabricated
exterior wall covering consisting of sheathing, insulation board,
reinforcing fabric, base coat, finish coat, adhesive and mechanical
fasteners as applicable. The system components shall be compatible with
each other and with the substrate as recommended or approved by, and the
products of, a single manufacturer regularly engaged in furnishing Exterior
Insulation and Finish Systems. All materials shall be installed by an
applicator approved by the system manufacturer. EIFS shall be [Class PB]
[or] [Class PM][as indicated] and shall be [_____] color and [_____] finish.
1.2.1
System Requirements and Tests
**************************************************************************
NOTE: The overall performance requirements will
vary with the design and geographic location of the
building, as well as with occupation, type of
construction, and other components specified.
Include only those systems tests required for the
particular building. Require full scale wall tests
where prior tests on similar wall designs are not
available or where the wall design differs
significantly from the design tested. If testing
for wind load, base the required pressure on wind
speed specified in IBC 2000. Higher values may be
used as required by applicable building code or
based on local experience of wind forces at the
site. Conduct tests both for positive and negative
pressure.
**************************************************************************
The system shall meet the performance requirements as verified by the tests
listed below. Where a wall system of similar type, size, and design as
specified for this project has been previously tested under the condition
specified herein, the resulting test reports may be submitted in lieu of
job specific tests.
1.2.1.1
Water Penetration
Test the system for water penetration by uniform static air pressure in
accordance with ASTM E 331. There shall be no penetration of water beyond
the plane of the base coat/EPS board interface after 15 minutes at 300 Pa (
6.4 psf), or 20% of positive design wind pressure, whichever is greater.
1.2.1.2
Wind Load
Test the system for wind load by uniform static air pressure in accordance
with ASTM E 330 (procedure A) to a minimum pressure of [_____] Pa [_____]
psf. There shall be no permanent deformation, delamination, or other
1.2.1.3
Full scale or intermediate scale fire test
Conduct wall fire test using apparatus, specimen, performance criteria, and
procedure in accordance with UBC 26-4. The specimen shall include the
complete system using 102mm (4 inch) thick insulation board. At the option
of the contractor, UBC 26-9, Intermediate-Scale Test may be substituted in
lieu of the Full-Scale Multi- Story Fire test. The following requirements
