On the Garden/First and Second floor units, the typical exterior wall furring occurs within each unit but the gypsum sheathing does not continue to the deck above. According to the 2009 IBC / 780 CMR, 708.1 a shaft is defined as “an enclosed space extending through one or more stories of a building, connecting vertical openings in successive floors, or floor and roof”. Per 708.2 Exception 1, a shaft enclosure is not required for openings totally within an individual residential dwelling unit and connecting four stories or less. As the exterior metal furring is not considered to be part of the exterior fire rated wall/partition, the existing 12” thick hollow brick wall meets the requirements for a 2 hour wall per table 720.1. The concrete floor assembly acts as the required ½ hour unit separation per 709.3 Exception 2, therefore we do not believe that the exterior metal stud wall meets the definition of a shaft wall and would not need draft stopping. Furthermore under 709.,4 Exception 6. fire blocking or draft stopping is not required at the partition line in buildings equipped with an automatic sprinkler system installed throughout in accordance with Section 903.3.1.1. or 903.3.1.2, provided that automatic sprinklers are installed in combustible floor/ceiling and roof ceiling spaces. Fire partitions require continuity from floor slab to rated floor/ceiling above, and we are providing this continuity on all floors at garden, first and second floor. The corridor walls and demising walls between units will be continuious from concrete floor slab to concrete slab above. We agree with your assessment that the continuity of the horizontal assembly must be maintained separating the third floor level from the attic space. Fire batt insulation will be provided at the top of all stud penetrations that are currently open to the attic in order to achieve the required separation between the third floor and the attic. (See attached Roxul data sheet) Spray foam Icynene Proseal MD-C-200V3 insulation meeting the definition of a “Limited- Combustible Material” per NFPA 13 4.3.1.6 when tested in accordance with ASTM E84 will be installed above the third floor ceiling (see attached data sheet), The material will be further isolated from the attic interior using an approved thermal barrier which also meets the definition CAOLO & BIENIEK ASSOCIATES, INC. ARCHITECTURE  PLANNING  INTERIOR DESIGN September 19, 2016 Re: Columns at Rockwell Place Page two of an ignition barrier for attics and crawl spaces in accordance with 780 CMR 2603.4.1.6. Unfaced blown in/fiberglass insulation that will be installed over the Icynene Proseal exceeds the 1 ½” minimum required thickness to serve as an ignition barrier protecting the spray foam. The fiberglass material is considered non-combustile per NFPA 13 3.3.1.6 where the flame spread rating is less than 25. Therefore the attic space is considered 100% non-combustible. The 5/8” gypsum type “X” wall board meets and exceeds the requirement for thermal barrier required for separating foam plastics from the interior of the building per 780 CMR 2603.4. If there are any questions or if additional clarification is needed, please do not hesitate to contact me. Very truly yours, Caolo & Bieniek Associates, Inc. Curtis A. Edgin, A.I.A.

ENERGY AND ENVIRONMENT COMPANY Johns Manville, a Berkshire Hathaway company, was founded in 1858. Our ownership by Berkshire Hathaway, one of the most admired companies in the world and one of the most financially secure, allows JM to invest for the future. This enables JM to continue delivering the broadest range of insulation products in the industry and offering innovative solutions that meet your needs. DESCRIPTION JM Formaldehyde-free™ thermal and acoustical insulation is made of long, resilient glass fibers bonded with a thermosetting resin. A wide range of thermal resistance R-values is available to provide thermal control for both vertical and horizontal applications. JM insulation is available unfaced or with a variety of facings, including kraft or foil vapor retarder. USE JM Formaldehyde-free™ thermal and acoustical insulation can be used in a wide variety of wood frame, engineered wood and steel frame construction applications, including: New Construction: residential homes and commercial buildings interior and exterior walls, floors and ceilings for thermal and sound control, as well as basement wall insulation. Retrofit: adding insulation to attics, crawl spaces and above suspended ceilings. INSTALLATION JM insulation cuts easily with an ordinary utility knife, and unfaced or tabless versions install easily by simply pressing in place between studs or joists in standard framing. Standard facings have stapling tabs for attachment to framing if additional securement is required. PACKAGING JM insulation is compression-packaged for savings in storage and freight costs. DESIGN CONSIDERATIONS Kraft and standard foil facings on this product will burn and must not be left exposed. It must be covered with gypsum board or another approved interior finish. Where an exposed application is required, use FSK-25 flame-resistant faced insulation. In colder climate areas, vapor retarders (whether attached to the insulation or applied separately) are often placed toward the heated or conditioned side of the wall. This is done to reduce water vapor penetration into the wall from the building interior. Check your local building codes for vapor retarder requirements. Refer to JM guide specifications for further design considerations and required installation instructions. LIMITATIONS OF USE Check applicable building codes. * Actual color of product may be lighter than image.
