Only encapsulated blanket should be utilized to ensure the outer surface of the insulation Is protected. The insulation system may be installed at zero clearance to combustibles at alt locations on the wrap, at material overlaps, and in the field between Overlaps. To minimize waste, FyreW►ap Elite 1.5 should be rolled out tautly before measuring and making any material Cuts. Install Insulation with a 3° minimum overlap on all joints. Seal all cut edges with aluminum foil tape. The transverse overlap of adjacent blanket may be installed using the following three techniques. See Figure 1 for details. Telescoping Overlap Wrap Technique: This wrap technique is the most common method of Installing FyreWrap Elite 1.5 where each adjacent blanket has one edge exposed and one edge covered by the next blanket, to form a 3 overlap. Checkerboard Overlep Wrap Technique.- This installation uses a 3` overlap pattem with both edges Of each alternating blanket covered by each adjacent blanket whose edges are exposed. The overlap joints in alternate layers of blanket resemble a Checkerboard pattern in the completed installation. This technique is often utilized when a small section of duct wrap Hurst be repaired, Butt Splice with Collar Wrap Technique: This wrap technique permits installation with the blanket edges butted together and a 8' wide collar of blanket that Is centered over the butt splice, overlapping each adjacent blanket 3'. The collar can be field fabricated from l=yreWrap Eke 1.5 rills orpurctrased separately.

Only encapsulated or scrim -faced blanket should be utilized to ensure the outer surface of the insulation is protected. The insulation system may be installed at zero clearance to combustibles at all locations on the wrap — at material overlaps and in the field between overlaps. Install insulation with a 3" minimum overlap on all joints. Seal cut edges with pressure- sensitive aluminum foil tape. The longitudinal overlap of adjacent blanket may be installed using any of the following three techniques. See Figure 1 for details. Telescope Overlap Wrap Technique — This wrap technique is the most common method of installing FyreWrap EZ 1.5 where each adjacent blanket has one edge exposed and one edge covered by the next blanket. Checkerboard Overlap Wrap Technique — This installation uses a 3" overlap pattern with both edges of each alternating blanket covered by each adjacent blanket whose edges are exposed. The overlap joints in alternate layers of blanket resemble a checkerboard pattern in the completed installation. This technique is often utilized when a small section of duct wrap must be repaired. Butt Splice with Collar WrapTechnique— This wrap technique permits installation with the blanket edges butted together and a 6" wide collar of blanket that is centered over the butt splice. overlapping each adjacent blanket 3 ". The collar can be field fabricated from FyreWrap EZ 1.5 rolls or purchased separately.

FyreWrapy EZ 1.5 Duct Insulation Installation The FyreWrap EZ 1.5 Duct Insulation consists of a single - layer system applied directly on to the duct surface. Only encapsulated or scrim faced one side blanket should be utilized to ensure the outer surface of the insulation is protected. The insulation system may be installed at zero clearance to combustibles at all locations on the wrap. at material overlaps, and in the field between overlaps. Install insulation with a 3" minimum overlap on all joints. Seal all cut edges with aluminum foil tape. The transverse overlap of adjacent blanket may be installed using the following three techniques. See Figure 1 for details. Telescoping Overlap Wrap Technique: This wrap technique is the most common method of installing FyreWrap EZ 1.5 where each adjacent blanket has one edge exposed and one edge covered by the next blanket. Checkerboard Overlap Wrap Technique: This installation uses a 3" overlap pattern with both edges of each alternating blanket covered by each adjacent blanket whose edges are exposed. The overlap joints in alternate layers of blanket resemble a checkerboard pattern in the completed installation. This technique is often utilized when a small section of duct wrap must be repaired. Butt Splice with Collar Wrap Technique: This wrap technique permits installation with the blanket edges butted together and a 6" wide collar of blanket that is centered over the butt splice. overlapping each adjacent blanket 3 ". The collar can be field fabricated from FyreWrap EZ 1.5 rolls or purchased separately.

Only encapsulated blanket should be utilized to ensure the outer surface of the insulation is protected. The insulation system may be installed at zero clearance to combustibles at all locations on the wrap — at material overlaps and in the field between overlaps. To minimize waste, FyreWrap Elite 1.5 should be rolled out tautly before measuring and making any material cuts. Install insulation with a 3" minimum overlap on all joints. Seal cut edges with pressure- sensitive aluminum foil tape. The perimeter transverse overlap of adjacent blanket may be installed using any of the following three techniques. See Figure 1 for details. Telescope Overlap Wrap Technique — This wrap technique is the most common method of installing FyreWrap Elite 1.5 where each adjacent blanket has one edge exposed and one edge covered by the next blanket. to form a 3" overlap. Checkerboard Overlap Wrap Technique — This installation uses a 3" overlap pattern with both edges of each alternating blanket covered by each adjacent blanket whose edges are exposed. The overlap joints in alternate layers of blanket resemble a checkerboard pattern in the completed installation. This technique is often utilized when a small section of duct wrap must be repaired. Butt Splice with Collar Wrap Technique — This wrap technique permits installation with the blanket edges butted together and a 6" wide collar of blanket that is centered over the butt splice, overlapping each adjacent blanket 3 ". The collar can be field fabricated from FyreWrap Elite 1.5 rolls or purchased separately.

Per your email dated May 10, 2010. it is my understanding that for the above referenced project, there is a 60" 1 24" grease duct wrapped with a single layer of FyreWrap EZ 1.5 Duct Insulation being supported by Unistrut hung with 5 8" or larger steel threaded rod. You also indicated that there is not 1" space present between the wrapped duct and the threaded rod. The tested /listed horizontal trapeze style support system utilizes a minimum 3/8" diameter all - thread steel rod and 1 ' X 1 '2" X Y" steel angle with a 1" space between the wrapped duct and the threaded rod. Based on the attached table 5 -3 (Allowable Loads in Pounds for Trapeze Bars) of SMACNA DUCT CONSTRUCTION STANDARDS for METAL AND FLEXIBLE Duct. the I ! x 1 1 ' d " is designated as an "F ". Transferring this "F'' to table 5 -4 ( Channel (Stiljt) Used as Trapeze) of the same SMACNA manual, the corresponding Unistrut size is 1 5i8" x 1 51 8 1 2g steel. With regard to the lack of 1 " space present between the wrapped duct and the threaded rod: Since the rod being used is at least 1 4" in diameter larger than the 318" listed, the I" space ' not necessary since the larger rod is much stronger. As long as the minimum corresponding Unistrut size is used. the support system does not need to be wrapped. Feel free to contact me with any questions or concerns. Thank •. ol}.

Technical Bulletin: FP- 2005 -4 June 24, 2005 Cup Head Pins and Carbon Steel Banding Approvals Unifrax has gained approvals from Omega Point Laboratories that improve the attachment method options available for all FyreWrap product versions. These approvals are detailed in the attached OPL Engineering Evaluation Letter. Individual FyreWrap Design Listings will be updated later in 2005 and Product Information Sheets will be updated upon the next printing cycle. These approvals specifically cover two attachment options: 1. Use of cup head insulation pins in lieu of pre - welded insulation pins, at same spacing. 2. Use of carbon steel bands in lieu of stainless steel bands, when used in combination with pins. 1. Cup Head Pins: OPL specifically states.. "The alternate use of cuphead pins «vith 1 3 %16 inch diameter or 1 ' inch diameter «ushers at the same pin spacing as the welded stick pins detailed in the Desi Listings will not reduce the fire resistance performance of the duct when tested to ASTM E 119, ASTM E 814, UL 1479, ,A pO O ��G� y. � O `9e ORATO o � y ASTM E 2336, ICC ES AC101, ISO 6944 and UL 1978." This approval will permit direct substitution of cup head pins for all FyreWrap product versions and Design Listings. The requirements for pins based upon duct size and the pin spacing remain unchanged. 2. Carbon Steel Banding, OPL specifically states: "The alternative use of carbon steel banding in conjuntion with pins and washers will not reduce the fire resistance performance of 16 GA. Ducts when tested to ASTM E 814, UL 1479, ASTM E2336, ICC ES AC 101, ISO 6944 and UL 1978. This approval will permit use of carbon steel bands for grease and ventilation ducts 16 GA. or thicker when pins are used as an additional method of attaelinent. Therefore, for ducts <24" in yt idth, piles are required on one side if carbon bands are to be used.

FyreWrap@ Duct Insulation typically used for grease duct applications is called FyreWrap@ .\ 2.0, which is a 2 -inch thick, 8 pcf blanket). While the FyreWrapiR) Duct Insulation called FyreWrap 1.5, which is it 1.5 -inch thick, 8 pcf blanket, is typically applied to HVAC ducts. FyreWrapkt Duct Insulation consists of a lnsulfrax D Blanket, which can be produced, in three different forms. Insulfrax 1800 8# Blanket is manufactured by melting calcium, magnesium, and silica into a molten ceramic then mechanically spinning the molten material into fibers.

FyreWrap® EZ IS Duct Insulation can be manufactured and packaged as is, backed with a layer of Poly- Aluminum Foil Scrim or Foil Scrim Foil on one face only, or totally enclosed within an envelope of the Poly - Aluminum Foil Scrim or Foil Scrim Foil, Test Criteria The Design Listings under consideration for possible revision teased on this evaluation here created based on AS TM E 119, UL 1978, AC 101, AC 179, and ASTM E "336 testing. Most of these Design Listings are based on an internal fire test, an engulfiient fire rest, penetration firestop test and a wall assembly fire test. The thermal transmission properties will remain the same regardless of the attachment method provided that the attachment method does not increase or decrease the thickness of the insulation material as originally tested. Therefore, this evaluation will only look at the effects of the fire on the alternative attachment methods. Evaluation The purpose of the evaluation is to determine whether using an alternate method to secure the Fyre'%IrapC Duct Insulation (F reWrapQRl A4AX 2.0 and FyreWraprl) 1.5) and Fyi'eWrapCK, EZ 13 Duct Insulation to the test assembly will adversely affect the results obtained during the test, which were a factor considered during the creation of the Desigm Listings. The internal fire test does not expose the attachment method to the source of the fire during the test. The banding option is not realistically applicable to the wall assembly fire test. Both the erigulfrnent fire resr and penetration firestop rest subject the attachment method to the fire. Obviously, the purpose of the attachment method is to secure the insulation system to the duct during its service life and in the event of a fire. In order to determine whether the cuphead pins and banding are acceptable alternative attachment methods, they must be compared to the tested attachment nietiiods.

Bre«rr Existing Attachment Provisions Currently one attachment option detailed in OPL Project No. 11$$91 and in the related Design Listings describing the location of impaling pins 'Wade from S inch long 12 gauge stainless steel that were welded to the duct on all sides. The blanket is secured to the duct with 2 -1/2 inch square stainless steel speed washers installed over the impaling pins to a snug fit, without considerable compression of the insulation. The pin placement pattern is generally described as rows of pins spaced approximately 8 inches on center in the longitudinal direction of the duct and rows of pins spaced approximately 10 -112 inches on center around the duct and this spacing is typically adjusted at transitions. A second attachment option is also detailed in OPL Project No. 106210 and related Design Listings. 10 gauge stainless steel impaling pins are'welded to the underside and to the rear vertical rise of the duct. After the duct. wrap is installed and the washers applied to the pins, the blanket is secured with nominal'.24nch wide, 0.013 -inch thick stainless steel ?sanding that is ti_,h.tened and secured with stainless steel banding clips. The banding was applied 1 -1. /? inches from the edge of the blanket at the overlapped joint and 10 -1/2 inches on center. Proposed Attachment Provisions One way to evaluate the proposed use of the cuphead pins would be to compare the surface area of their washers to the surface area of the tested washers. Another ay to evaluate the cuphead pins is to consider the insulation material being secured in place and the test used to evaluate the wrap system. When the insulation material is very friable and easily tern then the surface area of the washers would be a primary consideration. However, the insulation material is durable and not extremely friable. So the evaluation should focus on the ability of the cuphead pins to maintain the material in place during the tests. Since the pins only secure the dead load of the insulation material and that is their only purpose during the fire test, then comparing the dead loads would be applicable. It should be noted that proper attachment of the cuphead pins to the steel wall of the duct is critical to their performance. just as the proper attachment of the pins originally tested was critical. Based on the Bill spacing tested, a washer area of 6.23 square niches secures an insulation material area of 21 square inches. Therefore, the worse case scenario dead load condition in the Design Listings would be based on 21 square inches of 4 inches thick of S -pcf insulation or 0.39 lbs. Unifrax proposes using either cuphead pins with 1 3/16 inch diameter and 1 i..'z inch diameter washers or the worst case of 1.11 square inches. The issue is will the cuphead pin washer hold the 0.39 lb dead load. The speed washer is -secured by friction to the pin. The ; ctlpneaJ pin k ; rasher is , ,fielder# to the pin.

Brewer Page S of the wrap system is not significant enough to cause a failure of the cuphead pins or weakening of the insulation enough to allow a pull through of the cuphead pin based on the engulfment test and penetration test requirements. This information supports the alternative use of cuphead pins in all of the Unifrax Design Listings for ducts. The carbon banding issue is a little more complicated. The use of carbon steel banding is Lased on minimum �-% -inch wide and a minimum 0.0i5 thick. During an engulfment fire exposure, thin strips of carbon steel, such as banding, crystallize. They loose their tensile strength and break. However, the test method and application of the insulation material must also be considered because that is the basis primary of the Design Listing. When the banding breaks the insulation may fall off of the duct during an engulfment test. The issue then becomes what effect will Ioosing all or part of the insulation material have on the performance of the duct during the engulfment test and the penetration firestop test. During the hose stream test, experience has shown that the 16 GA steel grease duct will not allow a projection of water through its walls into its interior even when the insulation material is not fully intact. Unfortunately, while OPL possess some proprietary knowledge, general experience with the effect , d the loss of insulation material on t_he thermal transmission limitations set forth by the engulfment test is lacking. Therefore, the sole use of carbon steel banding, without using any pins, in an engulfment rest would need to he evaluated. The use of carbon steel banding in conjunction with some pins would be an allowable alternative. When all of the ends of the insulation material wrapped around the duct's circumference are secured with pins and then the carbon steel banding is used in addition to those pins, the concern about the insulation material being dislodged is eliminated. It is understood that ventilation ducts are normally lighter gauge steel and that the hose stream is not required during the ISO 6944 test. However, the general knowledge available to) OPL would not presently allow the use of carbon .steel banding fur use in Unifrax Design Listings tested ru ISO 6944 unless the duct i 16GA or h eavier. This information supports the use of carbon steel banding, with some pins, in all Unifrax Design Listings for 16 GA, and heavier, ducts. Conclusion Based on the ev aluation of the rest assemblies tested under OPL Projects and on the information contained, followed and referenced herein. it is Ome.Qa Point Laboratories' professional J udgment based on sound engineering principles rhat the following is true: The alternate use of cuphead pins with 1 .x/16 inch diameter or 1 !/z inch diameter washers at the same pin spacing as the welded stick pins detailed in the Design Listings will not reduce the fire resistance performance of the duct when tested to ASTIvI E 119, AST&I E N UL 147 9 A`TM E 's;6.

Brewer 5 / 20/05 Page 6 • The alternate use of carbon steel banding in conjunction with pins and washers will not reduce the fire resistance performance of 16 GA ducts when tested to ASTM E 814, UL 1479, ASTM E 2336, ICC ES AC101, ISO 6944 and UL 1978. The above will allow a revision to some of the existing Design Listings. Please contact David Neugebauer to discuss pricing and Tracie Sproles to discuss the lead time issue.
