'.VvC^MERICAN'IRON and steel instituM^^^TO^I Prepared by Ben H. Dyer, AIA-CSI Specifications Consultant USHO 002B57 . -\~* avv \ AIA FILE NO. 12 NOTES FOR SPECIFICATION WRITER INTENT These Suggested Guide Specifications for Stainless Steel Roofing, Flashings and Accessories are offered to the con struction industry to promote better specifications for stain less steel products and to provide the Specification Writer with'a workable manuscript that will assist him in writing individual project specifications for the items described herein. . The manuscript may be used as a separate section of a pro ject specification to specify stainless steel roofing, flashings and other stainless steel sheet metal work; or applicable parts of .the specification maybe inserted into other type of roofing specifications such as slate, tile, built-up, etc. The "Notes to Specification Writer" contain background in formation which is pertinent to the items included. These notes are intended to serve as a check list for items that are not included in the text and also to explain some of the vari ables that must be determined for each project. AIA FORMAT . CS1 FORMAT These Suggested Guide Specifications follow the format of the copyrighted AIA Specification Work Sheets with the consent of the American Institute of Architects. When the CSI Format For Building Specifications is used as the basis for numbering the project specification, the Metal Roofing, -Flashings and Accessories described herein would normally be located as one of the sections under Division 7 "Moisture Protection". This format requires each section number to be.'identified by a number and a letter; the number is that of the fixed.division under which the section is locat ed; .the letter-is any letter beginning with "A" and continuing alphabetical!jr/aS' necessary. REFERENCE TO SHEET METAL MANUALS References. are made herein to the following manuals; The Architectural Sheet Metal Manual First Edition, pub lished in 1965 by the Sheet Metal and Air Conditioning Contractors National Association, Inc., 107 Center Street, Elgin,'Illinois.'"

NOTES FOR SPECIFIC ITEMS 'AKlWi^EMENT-'bF TEXT "he text.dfitHese^uggesfed Guide Specifications is prepared nd arranged/ohVthe'-basis that the Stainless Steel Roofing,., 'lashingsjancf^bcesbo'ries will be a separate trade section f the' projdet/sppeification and the work will be performed s a sub-cdhtrapt'under- a General Contractor. Therefore !1 bids, ishopidrawings,' samples, etc. will be submitted trough the,-General' Contractor. For projects where a eneral Contractor is not engaged, the text should be modied accordingly; tragraphs 1 through 9 are generally applicable to the enre section. Paragraphs 10 through 36 describe only speci; items; however they are dependent to some extent upon `Stainless steel AISI Types 302 or 3M arejgehg.-tj;;; erall'y/recommended for normal flashln'gs/'and-'.C'; roofing work. .

For additional information concerning metals, finishes and other data such as recommended gauges, alloy types, avail able finishes, finish designations, joining methods, methods to reduce distortion and waviness, refer to the following publications. "Stainless Steel Data Manual, Suggested Practices for Roofing, Flashing, Copings, Gravel Stops, Fasclas and Drainage as published by The Committee of Stainless Steel Producers, American Iron and Steel Institute and dated August 1966. "Stainless Steel Architectural Fact Sheet", dated 1964 as prepared by the International Nickel Co., Inc. in cooperation with The Committee of Stainless Steel Producers, AISI. "Metal Finishes Manual", published 1964 by National Association of Architectural Metal Manufacturers, 228 N. LaSalle St., Chicago, 111. In most eases, the minimum gauges and metal thickness listed herein for specific items are in accordance with suggestions of the AISI Committee of Stainless Steel Pro ducers and accepted industry practices. Heavier gauges may be required for special conditions. NOTE 3 Solder should be used only as a means of filling or sealing joints; it should never be relied upon to provide structural strength. Where strength is required, joints should be fastened mechanically or welded. When it is considered necessary co have welded NOTE 4- joints in exposed metal work dressed smooth., the location of joints so treated should be specified. Dressing and finishing increases costs and is generally not neces sary in sheet metaL work except at eye level locations. NOTE 5 Where the Diamond Pattern is used for fiat seam roof, change size of sheet in the Guide Specifica tion to IS by 15 or 18 by 18 inches, and revise cleating re quirements accordingly. Where flat seam roofs occur on surfaces having a slope of 3 inches per foot or more and with adeouace drainage, seams may be sealed with white lead paste or an approved sealing compound in place of the solder specified. On very steep roofs such as spires and other roofs having slopes 6 inches per foot or more, sealing of joints may not be necessary, but a 3/4 inch edge fold should be specified. NOTE 6 Paragraph 14 (E) should be included as part of flat seam roof specifications only when expan- sion'-jolnts or expansion battens' are used to divide large roof areas . When-expansion joints'; are required, they should be locatfed and detailed.. ' ' The use of'expansion joints to break up large areas of low pitbhSi flat/'seam'' metal roofs.-is recommended by some manufactu'rers ito .'prevent, buckling of roofing sheets and the loosening of'shams and cleats.' There are other manufac turers who do not recommend the use of expansion joints. Recommendations of the manufacturer should be obtained and all conditions considered for each project. NOTE 7 Standing seam roofs are intended for application on slopes of 3 inches per foot or greater. Make provision for installation of wood nailing strips to receive cleats where deck material is not wood. The width of roof ing sheets should be specified; note that metal thickness in creases witn the sheet widen. Long pans up c, ot) feet may be used and are usually formed at the site wicli portable roiled pan forming equipment. (See Stainless Steel Data Manual for details.) A proprietary welded type standing seam roofing system uti lizing long pans formed at the site and portable welding machines may be used in place of the methods specified. If this system is used, consult manufacturers literature and revise the specification accordingly. See that sufficient electric service is available to operate the welding machines. NOTE 8 Batten seam,roofing is Intended for application on slopes of 3 inches per foot and greater; ,_how-'.; ever, some manufacturers recommend batten seam roofs on" slopes as low as 1-1/2 inches per foot where mechanical, type metal battens are used. Make provision for installing wood nailing strips to receive cleats where deck material is not wood. Care should be taken in spacing the battens to avoid waste from cutting the metal sheets. If a stock metal batten system is used, consult manufacturers details and revise this specification accordingly. NOTE 9 Metal base flashing is not generally recommend ed for built-up roof installations. It should be used, with built-up roofs only where composition base flash ings are not suitable. Adequate wood nailers must be pro vided for securing base flashing to decks. NOTE 10 When reflective finishes such as AISI No. 4 are used for gravel stops and fascias, care should be taken to control visual waviness. This is especially necessary at eye level locations and for wide fascias. Visual waviness may be reduced by increasing the metal thickness or by detailing ribbed, cross corrugated or curved profiles. Matte, textured or patterned finishes may not require special-] detailing. (Refer to the "Stainless Steel Data Manual" for/ suggestions concerning flatness.) '\'P, NOTE li The gauge or thickness of metal for gutters should be determined by the type and size'of gutters. Refer to Plate 1 Chart 6 of SMACNA Manual for recommended gauges based on girth of gutter. Also refer/ to Chart 7 on Plate 3 for recommended distance betweenex-, pansion joints for built-in gutters. NOTE 12 Where adjustable metal louvers, seif closing fire louvers or other special type louvers are required, revise the specifications accordingly. Louvers requiring duct connections should be provided with collar extensions unless this requirement is included as part of the, duct work. ` ADDITIONAL COPIES /.Additional copies, of-any of the Specifications -fpr {Stainless'Steel Stainless .Steel Revolying Doors ' Stainless,'S.teel Rolling Doors and Grilles "-I' Staiifless'sceel, Swinging Doors and Frames Z&sFi--r Stainless Steel Sliding Doors and Frames Stainless Steel Windows 'j Stainless Steel Curtain Walls,or Stainless <, ": 'f ~ Steel Components In Curtain Walls Stainless Steel Roofing, Flashings and Accessories. - .
