H. Exterior Curtain Wall Finish: The
exterior finish shall not create voids
or openings in the sandwiched wall
surface and shall extend at least 6
in. above and at least 24 in. below
the surface of the concrete floor
assembly. The following finishes are
acceptable:
(1)
Exterior
Insulation Finish System: Any Listed
and Labeled EIFS composed of an
expanded polystyrene foam (EPS)
insulation, and an Exterior Curtain
Wall
Finish
consisting
of
the
following: A plaster, base coat and
reinforcing mesh applied over the
sandwiched wall surface. Precut the
mesh as needed. The mesh is a
woven
fiberglass
reinforcement
fabric that is compatible with the
plaster base coat and finish coat
materials. Apply 1/16 to 1/8 in. thick
plaster base coat to the exposed
surface of the EPS foam. The EPS
foam boards nominally measure 24
in. wide by 48 in. long by a max. of 4
in. thick with a nominal density of 1
pcf. The EPS foam is attached to
the sandwiched wall surface using
mechanical
fasteners
or
an
adhesive
in
accordance
with
manufacturer’s
recommendations.
Install the EPS boards in a running
bond
(brick-like)
pattern
and
staggered over sandwiched wall
surface joints. Apply pressure to the
EPS boards to assist in the bonding
process. All EPS boards must be
butted together with no gaps or
voids between them. Allow a min. of
12 hours before continuing the
application process when using
adhesive. The EPS boards must be
rasped
to
remove
all
irregular
seams and establish a continuous
flat surface. Apply the mesh over
the EPS; embed the mesh into the
plaster base coat using a trowel.
Start at the middle and work
outwards towards edges. The final
thickness of the plaster base coat
with the mesh embedded should be
approximately 1/16 in.. Let the base
coat dry completely before applying
the plaster finish coat. The plaster
finish coat is a gypsum based wall
coating which may contain silica
sand or marble aggregates. Apply
the plaster finish coat using a trowel
in the same manner as the plaster
base
coat.
Other
installation
techniques are acceptable when
detailed by the manufacturer.
The
EIFS
system
is
a
monolithic
assembly
without
expansion
or
control joints. (2) Glass Panels:
Glass panels shall be sized and
installed to curtain wall framing
according to the curtain wall system
manufacturer's guidelines. Use a
min. 1/4 in. thick, clear, heat-
strengthened
(HS)
glass
or
tempered glass with a max. width
and height less than the framing oc
spacing, which allows the glass to
be secured between the notched
shoulder
of
the
framing
and
pressure bar. Panels are secured
with
a
thermal
break
(rubber
extrusion), pressure bar (extrusion),
min. 1/4-20 x 5/8 in. long screws,
and a snap face (extrusion) or other
manner
as
detailed
by
the
manufacturer. The system is a
monolithic
assembly
without
expansion or control joints. (3)
Aluminum Panels: Min. 1/8 in. thick
aluminum panels secured to the
steel-stud framing (Item 2B) in
accordance with the manufacturer’s
installation
instructions.
When
framing for the aluminum panels is
required, it is to be installed with the
manufacturer’s
installation
instructions.
The
system
is
a
monolithic
assembly
without
expansion or control joints. (4) Brick:
Use any conventional brick and
mortar type. Any brick pattern is
acceptable. Mortar joints not to
exceed 7/8 in. Secure bricks to wall
assembly
using
conventional
acceptable masonry construction
