adhesive. The EPS boards must be
rasped
to
remove
all
irregular
seams and establish a continuous
flat surface.
H. Exterior Curtain Wall Finish: Use
stone and mortar of any type. Mortar
joints not to exceed 7/8 in. Secure
stone wall finish to wall assembly
using
conventional
acceptable
masonry 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
(thermal-set rubber extrusion).
K. Window Framing: Steel framing
members hall 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
JOINT
PROTECTION:
The perimeter joint (linear opening) shall
not exceed an 8 in. nom. joint width
(joint width at installation) and the
perimeter
joint
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 width. Compress
the batt insulation into the perimeter
joint 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).
Reference the Introduction to Fire
Resistive Joint Systems Section of
this Directory for more details on
how to determine the cut width of
the insulation to be installed in the
nominal joint width, and how to
determine
the
compressed
percentage of a known insulation
width installed in a known nominal
joint width. (** Listed with Intertek)
