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.
H. Exterior Curtain Wall Finish: Use
cementitious, aluminum or steel
siding of any type. Install per
manufacturer's instructions.  Secure
siding
to
wall
assembly
using
conventional acceptable fastening
techniques.
I. Glass Vision Panels: Glass vision
panels shall be a min. 35-1/2 in.
above the top surface of the floor
assembly. Glass vision panels shall
be installed to curtain wall framing
according to the curtain wall system
manufacturer's guidelines. Use a
min. 1/4 in. thick, clear tempered
glass with a nom. width of 59 in. and
height of 71 in.
J. Window Gaskets: Secure glass vision
panels with a thermal break (thermo-
set rubber extrusion).
K. Window Framing: Steel framing
members shall be a min. 3-5/8 in.
by 1-5/8 in.  18 GA steel "U" channel
or
similar
construction
that
is
compatible with steel-stud framing
(2b).  Locate window framing at least
35 in. above the top surface of the
floor assembly.
3. PERIMETER
VOID
SPACE
PROTECTION:  The perimeter void
space (any wall cavity void between the
edge of the floor and the interior surface
of the sandwiched wall (2C) shall not
exceed an 8 in. nom. dimension and the
perimeter void space treatment shall
incorporate the following construction
features:
A.  Packing Material: Use a min. 4 in.
thick, 4 pcf density, mineral wool**
batt insulation installed with the
fibers running parallel to the slab
edge and curtain wall. The packing
material shall be compressed 33%
in the nominal joint void space.
Compress the batt insulation into
the perimeter void space such that
the top surface of the batt insulation
is flush with the top surface of the
concrete floor slab. Splices (butt
joints) in the lengths of mineral wool
batt insulation are to be tightly
compressed
together,
min.
compression 0.25 in.  per piece.
Notch packing material to receive
support angle (3C) so that packing
material
is
in
contact
with
Sandwiched Wall Surface (2C).

Resistive Joint Systems Section of
this Directory for more details on
how to determine the compressed
percentage of a known insulation
width installed in a known nominal
void space width. (** Listed with

Fill, Void or Cavity Material: To be
applied
(sprayed,
Brushed,

painted)
to
cover
the
entire
horizontal top surface of the mineral

space.
Apply
at
the

specified in Table 1 and overlap the
material a min. 1/2 in. onto the
Sandwiched Wall Surface (2C) and
Concrete Floor Assembly (1). If the
spraying process is stopped and the
applied

to
an
elastomeric film before process is
restarted, then overlap the edge of
the cured material at least 1/8 in.
with the spray. Reference Product
