nom. 2 in. thick 8 pcf density mineral
wool batt insulation faced on one
side with aluminum foil scrim (vapor
retarder), which is exposed to the
room interior. Secure with impaling
pins (Item 2D). Install the interior
face of the batt insulation, when
required compressed, flush with the
interior
face
of
the
aluminum
framing (Item 2B) creating a min.
1/2 in. air space between the
insulation and the glass panels
(Item 2C). When required, locate
horizontal seams in the insulation 6
in. below top surface of floor.
G. Framing Covers: Use only Intertek
certified mineral wool. Install nom. 1
in. thick, 4 in. wide strips of 8 pcf
density mineral wool batt insulation
faced on one side with aluminum foil
scrim (vapor retarder), which is
exposed to the room interior. After
the Fill, Void or Cavity Material (Item
3B) is installed, center framing
covers over vertical framing (Item
2B), mullions. Secure with impaling
pins (Item 2D) spaced a min. 1 in.
from both edges, and a max. 12 in.
o.c. Framing covers do not pass
through
the
perimeter
joint
protection (Item 3). Butt framing
covers to the top and bottom
surfaces of the perimeter joint
protection (Item 3).
3. PERIMETER
JOINT
PROTECTION:
Establish a max. joint (linear opening)
width of 2 in. (joint width at installation).
Incorporate the following construction
features:
A. Packing Material: Use only Intertek
certified mineral wool. Install min. 4
in. thick, 4 pcf density, mineral wool
batt
insulation
with
the
fibers
running parallel to the slab edge
(Item 1) and curtain wall. Compress
the packing material 50% and install
in the joint. Position the top of the
batt insulation flush with the top
surface
of
the
concrete
floor
assembly (Item 1). The compressed
packing material is secured against
the interior surface of the curtain
wall insulation (Item 2F), which is
supported by the 20 GA steel
reinforcing
angle
(Item
2E).
Compress splices (butt joints) in the
lengths
of
mineral
wool
batt
insulation tightly.
B. CERTIFIED
MANUFACTURER:
Hilti,
Inc.
CERTIFIED PRODUCT:  Joint Spray or
Sealant
MODEL: Firestop Joint SprayCFS-SP
WB or Silicone Joint Spray CFS-SP SIL
Fill, Void or Cavity Material: To be
applied (spray, brush, or trowel) to
cover the top exposed surface of the
packing material (Item 3A). Apply at
the thickness specified in Table 1
and overlap the material a min. 1/2
in. onto the adjacent curtain wall
assembly and concrete floor slab
assembly.
When
application
process is stopped and the applied
material cures to an elastomeric film
before the process is restarted, then
overlap the edge of the cured
material at least 1/8 in. with the new
material.
