Requested letter from Engineer of Record (MMM Project No. 180636900] Dear Sir:- The purpose of this letter is to respond to a request from the plan review authority, SAFEbuilt Inc. Colorado (in a notice dated 2010.06.25) that the "mechanical engineer provide a sealed and signed approval letter" per the 2003 IBC Section 106. 1, Colorado Revised Statutes, CRS 12 -25 -101 and Town of Vail requirements. The letter also requests that "plans be provided locating all grease ducts affected by the proposed change ". The following chronology summarizes MMM Group's review of two -hour fire -rated duct -wrap on the project: 2007.07.18 "Construction Set': Specification Section "15880, Air Distribution" of the project specifications, in Article "2.08 FIRE RATED DUCT WRAP INSULATION" called for "3M FireMaster Duct Wrap" and identified "Acceptable manufacturers are 3M Firemaster Systems (ThermoFire Systems Inc.), Royal Quickstop Fire Protection Systems Co., and Unif -ax Corporation (Tremco Canada)." And Article "3.06 INSTALLATION OF FIRE RATED DUCT WRAP INSULATION ", Paragraph "H, Installation shall be in strict accordance wih the manufacturer's instructions and recommendations and the requirements of the UL listing." 2008.01.14 "Fire Wrap Submittal No. 1 (Unifrax 1.5 Duct Insulation)": MMM Group returned "reviewed as noted" the Layton /KK submittal with direction to "keep extent of wap to a minimum and that the extend of two -hour drywall enclosures were shown on drawings" 2008.10.22 "Mechanical Site Instruction #43 - Acceptable Fire Wrap Locations" MMM Group issued clarification stating that "...fire -rated duct insulation is an accceptable alternative to fire -rated drywall enclosures for horizontal sections of duc ex c�t�_a grit COMMUNITIES RE VIEWE D BY TRANSPORTATION BUILDINGS �� �) `� Ltit1 i INFRASTRUCTURE � � - v SAFEbuilt Color ouirp rnpv Acceptability of UNIFRAX FyreWrap Elite 1.5 for fire rating of grease duct.

Per John Curtis, HKS Architects: "...Use of duct wrap for 2 hour enclosures - Both Mr. Plano and Mr. Haeberle ... had concern with the use of duct wrap throughout the project and requested that we review this and either provide documentation that wrap is acceptable throughout or revise the enclosures to drywall construction..... Upon reviewing the drawings issued in Bulletin 5, it does appear that the mechanical drawings have been updated to remove ductwrap in questionable locations and noted as 2 hour fire rated drywall enclosure. We do have detail 21 on A0.53 that shows the horizontal shaftwalll enclosure construction." 2008.12.15 "Fire Wrap Submittal No. 2 (3M Fire Barrier Duct Wrap 15A) ": MMM Group returned "reviewed as noted" the Layton /KK submittal with direction that "Single layer application is not acceptable in lieu of two -hour fire rated drywall orgypsum board construction." 2008.12.15 MMM Group copied Town of Vail and SAFEbuilt with: "Mechanical Site Instruction #43 - Acceptable Fire Wrap Locations ", "Fire Wrap Submittal No. 2 (3M Fire Protection Products - Fire Wrap Submittal + 3M Fire Protection Products - UL Fire Resistance Directory Illustrations - 2002 Edition) ". 2009.04.30 MMM Group internal communication: For the FSHR Vail CO project, MMM Group will entertain the use of the 3M or Unifrax or Thermal Ceramics fire wrap products proposed by Layton Construction / KK Mechanical, based on the following assumptions: 1.

The products are installed in accordance with their listing and the manufacturer's installation instructions. 2009.05.27 MMM Group (internal communication): In accordance with a request from Layton Construction that MMM Group assist in obtaining approval from the Town of Vail for the use of fire wrap in lieu of drywall enclosures, we reviewed and approved 3M product details - these approvals were not "single layer" application product[s]. Where is the Unifrax product that is the subject of the attached email going to be applied - is this forgrease duct, linen chute exhaust duct, or for what application? The core issue ... was 'Does the single layer application product have a UL- listing ?" The 3M product representatives [suggested] that approvals were still being sought for single layer application fire wrap products - and that only two -layer application products were UL- listed and therefore approved for use under the current applicable test standards that are identified in the International Building Code. There was an expectation that single layer products would eventually be approved by the adoption of newer fire- rating testing standards identified in the code - but this had notyet happened. Martin Haeberle (Town of Vail) made it clear that they would accept whatever the engineer was going to approve.... MMM Group is ... not prepared to accept anything less than the two -layer product - unless someone can demonstrate that the single layer product is an approved product. 2009.05.13 "Fire Wrap Submittal No. 3 (Unifrax FyreWrap EZ 1.5 Duct Insulation) ": MMM Group returned "reviewed" Layton /KK submittal.

The kitchen hood and some connecting ducting to the kitchen hood at the Four Seasons Hotel needed to be reinsulated due to water infiltration. The previously used grease duct insulation ( Fyrewrap EZ 1.5) was no longer available and had been had been discontinued. The manufacturer currently only produces the Fyrewrap Elite 1.5 for the grease duct insulation. Attached is a letter from the manufacturer confirming the Fryewrap Elite 1.5 used in a single layer system complies with the 2003 International Mechanical Code (IMC) with respect to commercial kitchen grease ducts and performs as a two hour fire rated enclosure. The product that was used is acceptable to Hyder and we have accepted the installation of this product on the project. The new grease duct insulation will provide the same level of quality as the originally submitted grease duct insulation at no additional cost to the project. Please reference the attached letter and product submittal data for more information and call with any questions or concerns. Respectfully yours, Michael Dire Design Coordinator Hyder onstruc 'on Inc. c: Jim Alotto- S REVIEWED BY SAFEbum +'oiorado June 4, 2010 Mr. Barry Schmitt Rocky Mountain Marketing Specialist Re: Four Seasons at Vail Vail, CO Dear Mr. Schmitt, This letter is to confirm that a single layer of FyreWrap Elite 1.5 Duct Insulation complies with the 2003 International Mechanical Code (IMC) with respect to commercial kitchen grease ducts. The specific code section in reference is section 506.3. 10 — Grease Duct Enclosure — Exception (1). This exception states that enclosure materials (i.e. - wraps) must be evaluated for such purpose, in accordance with a nationally recognized standard for such enclosure materials. That nationally recognized test standard in place for the 2003 IMC was UL 1978. A single layer of FyreWrap Elite 1.5 Duct Insulation was tested to and passes UL 1978 for a two hour fire endurance rating (see attached Intertek Design Listing UNI/FRD 120 -09).

Typical Product Parameters Thickness 1.5" Nominal Density 6pcf Standard Product Form Scrim Encapsulated Product Availability 24 "w x 25LF FyreWrap Elite ®1.5 Duct Insulation Installation The FyreWrap Elite 1.5 Duct Insulation consists of a single - layer system applied directly on to the duct surface. 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 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 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.

All overlaps shall be maintained at a minimum 3" and are to occur a minimum 6" from any corner of the duct. Pins spaced a maximum 8" on center are to be placed at the centerline of all vertically oriented overlaps. Pins may be pre - welded or cup head style pins. See Figure 3 for details. Attachment Options Three attachment options are available for installers. Choices are limited by the duct width dimension. Details on each option are provided below. Banding Only: For Duct Widths 24" or Less To temporarily secure the insulation, optional use of filament tape is permitted. Place carbon steel or stainless steel bands (min. 1 12" wide, nom. 0.015" thick) over joints and within the field between joints, around the wrap. Locate bands 1 %" from each edge of the blanket, centered on the overlap, and on 10 centers. Tighten banding to firmly hold the wrap system in place but not so tight as to cut or damage the blanket. Pins are NOT required when this banding technique is used. Banding and Pins: For Duct Widths <— 48" Weld 12 -gauge steel insulation pins to the underside of horizontal runs and backside (side of duct having largest dimension) of vertical runs. Place pins at maximum 12" rows and on maximum 10'1h" centers. To temporarily secure the insulation, optional use of filament tape is permitted. Impale FyreWrap Elite 1.5 over the pins and hold in place with 2f" square galvanized steel speed clips (washers). Turn down or cut off exposed ends of pins to eliminate safety hazards. Locate carbon steel or stainless steel bands (min. h" wide, nom. 0.015" thick) 1 X" from each edge of the blanket, centered on the overlap, and on 10;x" centers. Tighten banding to firmly hold the wrap system in place but not so tight as to cut or damage the blanket. Cup head style pins are also permitted and shall be located at the same spacing as pre - welded pins. Pins Only: For Duct Width > 48" Weld 12 -gauge steel insulation pins on all sides of the duct. Place insulation pins in rows (perpendicular to the length of the duct) spaced maximum 10'1" on center. Pins in each row are maximum 6" from each duct edge and maximum 8" on center. Locate insulation overlaps so they are centered on the pins. Impale FyreWrap Elite 1.5 over the pins and hold in place with 2%" square galvanized steel speed clips (washers) to keep the system from sagging. Turn down or cut off exposed ends of pins to eliminate safety hazards. Cup head style pins are also permitted and shall be located at the same spacing as pre - welded pins. The pin only attachment method can be used for duct widths less than 48 ", but is optional. Figure 3.

Use blanket that is fully encapsulated, single faced, or unlaced. The blanket is installed in min. 24 -in. wide sections. Pre - welded or cup head pins (3) and /or min. 1 /2 -in. wide nom. 0.020 -in. thick carbon steel bands or min. 1 /2 -in. wide nom. 0.015 -in. thick stainless steel bands are applied (4) to maintain the blanket up against the duct to reduce sagging and to assist in the installation of vertical sections. Wrap the steel duct with one layer of duct wrap (facing exposed) with 3 -in. min. overlaps at all joints. Install insulation with a nom. thickness of 3 in. at the overlap for FyreWrap® Elite 1.5, FyreWrap EZ 1.5 or the FyreWrap 1.5 application, or a nom. thickness of 4 in. at the overlap for FyreWrap MAX 2.0 application. The wrap system may be installed with zero clearance to combustible construction at the overlaps and in the field between the overlaps. Make the transverse overlaps of adjacent blankets (2A) using one of the following three methods as depicted in the drawings: 3 -in. overlap telescoping method where each adjacent blanket has one edge exposed and one edge covered by the next blanket, •3 3 -in. overlap checkerboard pattern where both edges of each alternating blanket are covered by each adjacent blanket whose edges are exposed, or butt splice with collar method where the blankets are butted together and a 6 -in. wide collar of blanket is centered over the butt splice overlapping each adjacent blanket 3 -in. For vertical runs, the insulation can be applied to the duct in a continuous length applied parallel with the length of the duct as opposed to wrapping around the duct. All overlaps are to be maintained at a min. 3 in. and are to occur a min. of 6 in, from any corner of the duct. Pins (3) spaced a maximum 8 in. o.c. are to be placed at the centerline of all vertically oriented overlaps. Seal all exposed fiber with min. 4 -in. wide, pressure- sensitive aluminum foil tape. Secure with min. 1 /2 -in. wide nom. 0.020 -in. thick carbon steel bands or min. 1 /2 -in. wide nom. 0.015 -in. thick stainless steel bands (4) or pins (3).
