reinforcement
fabric
that
is
compatible with the cementitious
base coat and finish coat materials.
Apply
1/16
to
1/8
in.
thick
cementitious
base
coat
to
the
exposed surface of the EPS foam.
Apply the mesh; embed the mesh
into the cementitious base coat
using a trowel. Start at the middle
and work outwards towards edges.
The
final
thickness
of
the
cementitious base coat with the
mesh
embedded
should
be
approximately
1/16
in.
Let
the
cementitious
base
coat
dry
completely
before
applying
the
cementitious
finish
coat.
The
cementitious finish coat is a cement
based wall coating which may
contain
silica
sand
or
marble
aggregates. Apply the cementitious
finish coat using a trowel in the
same manner as the cementitious
base coat.
G.  Glass Vision Panels: 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 that is fitted to
the framing, having a min. width of
24 in.  and  min. height of 24 in.
H.  Window
Gaskets:
Secure
glass
vision panels with a thermal break
(thermal-set rubber extrusion).
I.  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
6 inches above the top surface of
the floor assembly.
3.  PERIMETER
JOINT
PROTECTION:
The perimeter joint (linear opening) shall
not exceed a 6 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 25%
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
and the insulation is compressed
against the interior surface of the
curtain wall insulation (2D).  Splices
(butt joints) in the lengths of mineral
wool batt insulation are to be tightly
compressed together.  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)
