<br />General
<br />Cut edges of the blanket shall be taped with aluminum foil
<br />tape to prevent exposed edges Of the insulation absorbing
<br />grease and moisture in the event of a compromised grease
<br />duct joint or condensation. Overlaps and/or tightly butted
<br />joints are used to block heat transfer in the event of duct
<br />deformation resulting from thermal expansion. Filament
<br />tape is suggested to hold the blanket in place until steel
<br />banding or pinning is installed to permanently secure the
<br />blanket.
<br />A. Installation on Grease Duct per ASTM E2336 and
<br />CANMLC S144 (Figure 1)
<br />System requires two layers of insulation applied directly to
<br />the duct with tight butt joints at all seams on both layers.
<br />The first layer of insulation is cut to a length sufficient to
<br />wraparound the duct and provide a tight butt oint where
<br />p 9 1
<br />the blanket ends meet. layer
<br />Adjacent blankets on the first la
<br />1 Y
<br />are butted tightly together with longitudinal seams offset
<br />9 Y o9 9
<br />minimum 6" The second ) 150mm . layer of insulation is
<br />(
<br />installed in the same method as the first layer, with seams
<br />between layers offset a minimum of 6" (150mm). Banding
<br />and/or pinning per Section D is used to permanently
<br />secure the insulation to the duct.
<br />B. Installation on HVAC Duct per ISO 6944 (Figure 1)
<br />System requires one layer of insulation applied directly to
<br />the duct with 3" (75mm) overlaps at all seams. The
<br />insulation is cut to a length sufficient to wrap around the
<br />duct and provide a 3" (75mm) overlap where the blanket
<br />ends meet. Adjacent blankets are installed to provide a
<br />minimum overlap of 3" (75mm). Banding and/or pinning per
<br />Section D is used to permanently secure the insulation to
<br />the duct.
<br />C. 2 & 3 Sided Wrap Installation (Figure 4)
<br />When space does not allow for a complete wrap applied to
<br />the duct on all four sides, the FastWrap XL is approved for 2
<br />Or 3 sided installations with mechanical attachment to a rated
<br />concrete or CMU assembly. (See Figure 4 for installation
<br />details.)
<br />D. Mechanical Attachment Methods
<br />1) Banding (Figure 1)- Minimum 1/2" (13mm) wide
<br />carbon steel Or stainless steel banding, 0.015" (0.4mm)
<br />thick is placed around the entire perimeter of the
<br />insulated duct on maximum 10-1/2" (270mm) centers
<br />and 1-1/2" (38mm) from each blanket edge or 1-1/2"
<br />(38mm) from each collar edge when using the butt joint
<br />U Morgan
<br />CAdvanced Materials
<br />and collar method. The banding is placed around the
<br />blanket and tightened to firmly hold the FastWrap XL in
<br />place against the duct, but not cause any cutting or
<br />damage to the blanket.
<br />2) Pinning - Pinning on all sides of the duct may be used
<br />as an alternative to banding. For ducts wider than 24"
<br />(610mm) pinning is required on the bottom of horizontal
<br />runs, or on one side of vertical runs (in addition to steel
<br />banding). When applicable, 12 Gage (0.4mm) steel pins
<br />are installed on 12" (305mm) centers along: the width of
<br />the duct and 10-1/2" (270mm) centers along the length
<br />of the duct. Pins that extend beyond the outer blanket
<br />layer shall be turned down or the excessive length cut
<br />off to prevent sharp edges. Shoot through pins (cup
<br />head pins) may be used in conjunction with steel
<br />banding to prevent blanket sag.
<br />E. Access Doors
<br />M
<br />1 FastDoor XL (Figure 3 - FastDoor XL is a UL Listed
<br />) ( 9 ) ,
<br />liquid tight duct cover panel supplied complete with a
<br />single layer insulation cover per UL Listing HNKT G18.
<br />The FastDoor XL is installed per included installation
<br />instructions. No field welding is required.
<br />2 Field Fabricated Access Doors - Each access door
<br />assembly has four threaded rods 1/4 inch (6mm) in
<br />diameter and 5" (127mm) in length, with one welded to
<br />each corner of the door opening. Hollow steel tubes,
<br />4-1/2" (114mm) long are installed outside the access
<br />cover plate and over the threaded rods. Four 12 gage
<br />(3mm) and 4-1/2" (114mm) long steel insulation pins are
<br />welded to the access cover plate to allow for installation
<br />of the three layers of FastWrap XL. One layer of
<br />FastWrap XL is cut to approximately the same size as
<br />the access panel, and impaled over the insulation pins
<br />on the panel. A second layer of FastWrap XL is cut so
<br />as to Overlap the first layer a minimum of 1-1/2" (38mm).
<br />It is essential that the first and second layer fit tightly
<br />against the surrounding wrap with no through openings.
<br />The third and outside layer should be cut to overlap the
<br />second insulation layer by minimum of 1-1/2" (38mm).
<br />Minimum 1-1/2" (38mm) round or square insulation clips
<br />are installed on the insulation pins to secure the three
<br />layers of insulation to the access cover plate. All cut
<br />edges of the insulation shall be taped with minimum 3"
<br />(75mm) wide aluminum foil tape. Wing nuts and
<br />washers are installed on the four threaded rods, and
<br />tightened against the hollow steel tubes to seal the

<br />F. Through Penetration Firestop System (Figure 2) -
<br />When the duct penetrates a fire rated assembly an
<br />approved fire stop system must be employed. Figure 2
<br />provides a complete list of UL / ULC firestop design
<br />listings which can be found in the Certifications Directory
<br />at vwAM.ul.com for US systems and www.ulc.ca for
<br />Canadian systems. Prior to installing any firestop system
<br />the surfaces of all openings and penetrating items must
<br />be clean and dry. The FastWrap XL core blanket (or
<br />mineral wool where allowed b the firestop design listing)
<br />Y p 9 9)
<br />must be compressed into the annular space. The
<br />packing material must be recessed a minimum depth
<br />from the surface of the concrete or gypsum assembly.
<br />The recessed opening must be filled with a minimum
<br />thickness of an approved firestop sealant. The packing
<br />material type and compression, minimum recess
<br />p
<br />(typically 1/4" 6mm and approved firestop sealant and
<br />(21'p Y ( )) pP p
<br />thickness(typically 1/4" (6mml shall be asspecified in an
<br />approved UL / ULC firestop design listing. When there
<br />pp p 9 9
<br />is not sufficient annular space around the duct to run the
<br />FastWrap XL enclosure system continuous through the
<br />fire rated assembly, the enclosure may terminate above
<br />and belowthefloor/ceilin9 Y assembl or On either side Of
<br />a wall assembly as shown in Figure 2. When this method
<br />is used, the FastWrap XL must be mechanically attached
<br />on either side of the fire rated assembly using one of the
<br />attachment methods described in Section D, spaced a
<br />maximum of 1-1/2" (38mm) from the fire rated assembly.
