without restriction.
2. CURTAIN
WALL
ASSEMBLY:
Incorporate the following features:
A. Mounting Attachment: (Not shown)
Attach the aluminum framing (Item
2B) to the structural framing in
accordance with the curtain wall
manufacturer's instructions. When
required,
connect
the
mounting
attachments to the joint face of the
concrete floor assembly (Item 1), in
accordance with the curtain wall
manufacturer's instructions. Max. 10
ft.
distance
between
mounting
attachments.
B.  Aluminum Framing: Size rectangular
aluminum
tubing
mullions
and
transoms according to the curtain
wall
system
manufacturer's
guidelines but not less than the
following requirements. Min. 0.100
in. thick aluminum with a min. 5 1/4
in. height with framing cover (Item
2G) and a min. of 2-1/2 in. width of
the extrusion. Add framing covers
(Item 2G) to the external side of the
aluminum framing. Space mullions a
min. 60 in. on center (oc) and
spandrel transoms spaced a min. 47
1/2 in. oc  Locate spandrel transoms
at a min. height 20 in. above the top
surface
of
the
concrete
floor
assembly (Item 1) (as measured
from the bottom of the transom).
C. Glass Panels: Size and install glass
panels to curtain wall framing in
accordance with the curtain wall
system manufacturer's guidelines.
Use min. 1/4 in. thick clear, heat-
strengthened (HS) glass with a max.
width and height less than the
aluminum framing (Item 2B) o.c.
spacing, which allows the glass to
be secured between the notched
shoulder of the aluminum framing
(Item 2B) and pressure bar. Secure
glass panels with a thermal break
(rubber extrusion), pressure bar
(aluminum extrusion), min. 1/4-20 x
5/8 in. long screws, and a snap face
(aluminum extrusion).
D. Impaling Pins: Size and install min.
12 GA steel pins min. 1/2 in. longer
than the thickness of the curtain wall
insulation (Item 2F). Attach pins to
nom. 2 in. by 2 in. by 2 in. 20 GA
galvanized
sheet
steel
Z-clips.
Secure the Z-clips to the aluminum
framing (Item 2B) with one (1) No.
10 self-tapping sheet metal screw
each. Space pins max. 12 in. o.c on
the vertical framing members (Item
2B) and a max. 20 in. oc on the
horizontal framing member (Item
2B)
above
the
concrete
floor
assembly (Item 1). Install the
interior face of the curtain wall
insulation (Item 2F) so that it is flush
with
the
interior
face
of
the
aluminum framing (Item 2B).
E. Reinforcing Angle: Create a min. 1-
1/2 in. x 1-1/2 in. x 20 GA
galvanized steel angle with 6 in.
vertical legs at each end. Position
the galvanized steel angle so that
the vertical leg serves as a backer
to the exterior face of the curtain
wall insulation (Item 2F) and the
horizontal leg extends away from
the curtain wall insulation (Item 2F).
Locate the galvanized steel angle at
the elevation of the centerline of the
perimeter joint protection (Item 3).
Size the galvanized steel angle 12
in. longer than the span between the
interior
edges
of
the
vertical
aluminum
framing
(Item
2B),
mullions. Form the galvanized steel
angle so that it has a 6 in. vertical
leg on each end. Secure the 6 in.
vertical leg to the vertical aluminum
framing (Item 2B) on each side with
three No. 10 steel self-tapping sheet
metal screws placed in a triangular
fashion with a max. spacing of 2 in.
