Door Hardware
• An approved firestop sealant
General:
To minimize waste, FastWrap XL blanket should be rolled out tautly
before measuring. Cut edges of the blanket shall be taped with alu-
minum foil tape to prevent exposed edges of the insulation from
wicking moisture from condensation or grease from a compromised
leaking duct joint into the material and causing degradation of the
fire barrier. Overlaps are used to block heat transfer in the event of
duct deformation resulting from thermal expansion. FastWrap XL
blanket may be installed with either a mechanical banding system or
insulation pins and clips (see Mechanical Attachment Methods
below and figures 1 and 2). Support hanger systems do not need
to be wrapped provided that the hanger rods are at least a minimum
of
3 ⁄
8
" diameter and spaced a maximum of 60" on center along the
length of the duct, and the angle iron is a minimum of 2" x 2" x 1 /
8
"
or SMACNA equivalent support system (SMACNA band strap sup-
port do not apply). Horizontal trapeze support system may be incor-
porated into the wrap enclosure.
A. First Layer – Butt Joint (Figure 2)
The first layer of FastWrap XL is cut to completely wrap around the
perimeter of the duct with enough excess to provide a tight butt joint
where the blanket ends meet. The joints of adjacent blankets are
firmly butted against each other. This interior layer can be held tem-
porarily in place with filament tape spaced 1-1/2” from each blanket
edge, and spaced on nominal 10-1/2” centers along the center of
the blanket. While not required, the inside layer can be installed
with 3” overlaps along perimeter and adjacent blankets.
B. Second Layer – 3” Overlap, or 6” Collar (Figure 2)
The second layer of FastWrap XL is cut to completely wrap around
the perimeter of the first layer, with enough excess to overlap itself
not less than 3”. Joints in the second layer should be staggered a
minimum of 12 inches from joints on the inner layer. Adjacent blan-
kets on the second layer must overlap each other by not less than
3”. As an alternative to overlaps on adjacent blankets installed on
the second layer, adjacent blankets can be tightly butt jointed and
wrapped with a 6” wide FastWrap XL collar centered over the butt
joint. This outside layer can be held temporarily in place with fila-
ment tape spaced 1
1 ⁄
2
” from each blanket edge, and spaced on nom-
inal 10 1 ⁄
2
” centers along the center of the blanket. Mechanical
attachment as described in Section D must be used to make the
installation permanent
C. 2 & 3 Sided Wrap Installation (Figure 1)
When space does not allow for a complete wrap applied to the duct
on all four sides, the FastWrap XL is approved for 2 or 3 sided instal-
lations with mechanical attachment to a concrete or CMU assembly.
The FastWrap XL is installed on the 2 or 3 sides of the duct as
described in one of the installation methods described in sections A
or B with the starting edge of the blanket attached to the concrete or
CMU assembly and then wrapped around the duct until the other
end can be affixed to the other concrete or CMU assembly, thus
encapsulating the duct with insulation around all accessible sides.
The blanket is to flange out onto the concrete or CMU assembly. It
shall be secured to the adjoining assembly with min
3 /
16
" diameter, 4"
long concrete anchors, footed to a minimum 1 1 ⁄
2
" wide x 3 /
16
" thick
steel strip/strap with pre-drilled holes spaced a maximum 10" on
center. The steel strip is to be placed around the entire perimeter of
the duct in the exposure area. The FastWrap XL insulation wrap is
secured to the duct with minimum
1 ⁄
2
" wide steel banding 10 1 ⁄
2
" cen-
ters. The ends of the banding are to loop into the steel strips/straps
that foot the blanket to the concrete floor or wall, and tightened
down. The trapeze support system may be incorporated within the
wrap system.
D. Mechanical Attachment Methods for Insulation Wrap
1. Banding (Figure 2) - Minimum 1 ⁄
2
" wide carbon steel or stainless
steel banding, 0.015" thick, is placed around the entire perimeter of
the insulated duct with maximum 10
1 ⁄
2
" spacing centers and 1 1 ⁄
2
" from
each blanket edge or 1 1 ⁄
2
" from each collar edge when using the butt
joint and collar method. When banding, filament tape can be used
to temporarily hold the blanket in place until the banding is applied.
The banding is placed around the material and tightened so as to
firmly hold the FastWrap XL in place against the duct, but not cause
any cutting or damage to the blanket.
2. Pinning (Figure 3) - For duct spans 24" or larger, min. 12 gage,
5" long steel insulation pins are welded to the duct in columns
spaced 12" apart, 6" - 12" from each edge and on 10
1 ⁄
2
" centers
along bottom horizontal and outside vertical runs to prevent blanket
sag. Pins are also required 1" from the end of a duct and 1" from
any edge near a 90° bend, spaced on 6" centers. Pins are locked
into place with 1
1 ⁄
2
" diameter round or square, galvanized steel,
speed clips or cup head pins. Pins that extend beyond the outer
blanket wrap layer shall be turned down to eliminate sharp edges or
the excess length cut off.
E. Grease Duct Access Door Installation (Figure 4)
Four galvanized steel threaded rods, 1 ⁄
4
" diameter by 4 1 ⁄
2
" to 5" long
are welded to the duct at the corners of the door opening. Four 4"
long steel tubes fit over the threaded rods to hold the door to the
duct and protect the wrap from damage as the door is removed.
Four 5" long 12 gage insulation pins are welded to the door panel
for installation of the blanket. Three layers of FastWrap XL are
impaled over the 12 gage insulation pins on the 16 gauge door
panel and held in place with speed clips. Each layer must have min-
imum 1” overlap over the previous layer. When the door is installed,
this first and second layer must fit tightly against the wrap surround-
ing the door opening to form tight butt joints. Pins that extend
beyond the outer layer of FastWrap XL shall be turned down to
avoid sharp points on the door. The steel tubes are placed over the
threaded rods. The insulated door panel is placed over the thread-
ed rods covered by the steel tubes and held in place with washers
and wing nuts. FireMaster F2-HT-XL3 Access Doors are tested and
approved per ESR 2213 as alternatives to field fabricated doors.
Installations instructions for the F2-HT-XL3 door are included with
the complete assembly.

F. Through-Penetration Fire Stop System (Figure 5)
When the duct penetrates a fire rated wall, ceiling, or floor, an
approved fire stop system must be employed.
Prior to installing this firestop system the surfaces of all openings and
penetrating items needs to be clean and dry.
Cut the aluminum scrim facing off FastWrap XL blanket to expose the
core blanket. FastWrap XL scrap blanket must be packed into the
annular space at minimum 50% compression. The packing material
must be recessed a minimum
1 ⁄
4
" from the surface of the concrete or
gypsum wall. Install a minimum of 1 ⁄
4
" of approved firestop sealant
into the recessed opening. When there is no room in the remaining
annular space to wrap the duct with FastWrap XL material, the
enclosure may terminate above and below the floor/ceiling or wall
assembly as shown in figure 5 by mechanically attaching the
FireMaster to the termination point above and below the termination
area with bands or pins.
9. Maintenance and Repair
No maintenance is required when installed in accordances with
Thermal Ceramics installation instructions.
If damage is limited to the foil facing, aluminum foil tape can be used
to repair the foil facing.
If an area of blanket is found to be damaged the following procedure
must be incorporated.
• If the damaged area is larger than 8” x 8” the entire wrap section
must be removed and replaced according to Thermal Ceramics
installation instructions.
• If the damaged area is small (less than 8” x 8”), the damaged area
must be cut away and replaced with a new section 1” larger in length
and width than the cut out are, such that the new section can be
compressed tightly into the cut out area. All cut edges of the new
section must be taped and sealed wth aluminum foil tape. The new
section must be held in place with either pinning or banding per
Thermal Ceramics installation instructions/
10. Limitations
