secured in an 18 GA steel track top
and bottom using #6 x 1.25 in. Bugle
head SD PT screws. Vertical framing
shall not exceed a spacing of 24 in.
on center (oc).
C.  Sandwiched Wall Surface: Use a
min. 1/2 in. thick, 48 in. wide by 96
in. long, exterior grade gypsum
wallboard (ASTM C 79), cement
board,
or
fiberglass
sheathed
gypsum wallboard placed over and

E.  Barrier Insulation: Use a nom. 24-in
wide by 4 in. thick min. 4 pcf faced
or un-faced mineral wool** batt
insulation cut to size as required.
Install barrier insulation in each stud
cavity so that min. 32 in.  of barrier
insulation is above the top surface of
the slab and a min. of 24 in.  is
below the bottom surface of the slab.
Barrier insulation length is min. 24
in.  and fitted tightly between vertical
framing members filling all studs.
Seal
all
butt
joints
of
barrier
insulation with min. 4 in.  wide
aluminum
foil
faced
tape.
The
curtain
wall
insulation
shall
completely fill the recess of the min.
3-5/8 in. by 1-5/8 in., 18 GA steel "C"
studs. (** Listed with Intertek)
F.  Interior Curtain Wall Surface: Apply
after Perimeter Cavity Protection (3)
is installed.  Use a min. 1/2 in. thick,
48 in. wide by 96 in. long, Type X
gypsum wallboard (ASTM C 36),
placed over and secured to framing
with #6 by 1-1/4 in.  long Type S
drywall screws 8 in. oc on the
periphery and 12 in. oc in the field.
Screw heads are covered with joint
compound. Joints created between
gypsum wallboard are taped and
floated
with
joint
compound.
Gypsum wallboard only required to
be continuously placed a min. 32 in.
above the top surface of the slab.
Gypsum wallboard below the slab is
optional.
G. Exterior Curtain Wall Insulation: An
Exterior Insulation Finish System
(EIFS) is composed of an expanded
polystyrene foam (EPS) insulation,
and a Exterior Curtain Wall Finish
(2H).
The
EIFS
system
is
a
monolithic
assembly
without
expansion or control joints.  The
EPS foam boards measure 24 in.
wide by 48 in. long by 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 (2C) joints.
