Section includes glazing for the following products and applications, including those specified in other Sections where glazing requirements are specified by reference to this Section: 1. Windows. 2. Doors. 3. Glazed curtain walls. 4. Storefront framing. 5. Glazed entrances. 6. Sloped glazing. 7. Skylights. 8. Interior borrowed lites. 1.2 PERFORMANCE REQUIREMENTS A. General:  Installed glazing systems shall withstand normal thermal movement and wind and impact loads (where applicable) without failure, including loss or glass breakage attributable to the following:  defective manufacture, fabrication, or installation; failure of sealants or gaskets to remain watertight and airtight; deterioration of glazing materials; or other defects in construction. B. Delegated Design:  Design glass, including comprehensive engineering analysis according to ICC's 2003 International Building Code by a qualified professional engineer, and by analyzing Project loads and in-service conditions.  Provide glass lites for various size openings in nominal thicknesses, but not less than thicknesses and in strengths (annealed or heat treated) required to meet or exceed design data. 1.3 SUBMITTALS A. LEED Submittals: 1. Product Data for Credit EQ 4.1:  For glazing sealants used inside of the weatherproofing system, including printed statement of VOC content. 1.4 GLASS PRODUCTS, GENERAL A. Thickness:  Where glass thickness is indicated, it is a minimum.  Provide glass lites in thicknesses as needed to comply with requirements indicated. 1. Minimum Glass Thickness for Exterior Lites:  Not less than 6.0 mm. B. Strength:  Where float glass is indicated, provide annealed float glass, Kind HS heat-treated float glass, or Kind FT heat-treated float glass.  Where heat-strengthened glass UNIVERSITY of  NEW HAMPSHIRE    PLANNING, DESIGN AND CONSTRUCTION GUIDELINES January 25, 2013 CHAPTER 5 – TECHNICAL CONSTRUCTION AND RENOVATION STANDARDS GLAZING 08 8000 - 2 is indicated, provide Kind HS heat-treated float glass or Kind FT heat-treated float glass.  Where fully tempered glass is indicated, provide Kind FT heat-treated float glass. C. Thermal and Optical Performance Properties:  Provide glass with performance properties specified, as indicated in manufacturer's published test data, based on procedures indicated below: 1. Distortion of glass is unacceptable. The exterior lights of all glazing should appear flat and should not show deflection due to pressurization between the interior and exterior lights. Select appropriate glass thickness and intermediate air space to minimize deflection and specify the most current industry standards for flatness. 2. For monolithic-glass lites, properties are based on units with lites 6.0 mm thick. 3. For laminated-glass lites, properties are based on products of construction indicated. 4. For insulating-glass units, properties are based on units of thickness indicated for overall unit and for each lite. 5. U-Factors:  Center-of-glazing values, according to NFRC 100 and based on LBL's WINDOW 5.2 computer program, expressed as Btu/sq. ft. x h x deg F (W/sq. m x K). 6. Solar Heat-Gain Coefficient and Visible Transmittance:  Center-of-glazing values, according to NFRC 200 and based on LBL's WINDOW 5.2 computer program. 7. Visible Reflectance:  Center-of-glazing values, according to NFRC 300. D. Warranty: Provide 10 year minimum warranty on insulated glass units. 1.5 GLASS PRODUCTS A. Float Glass:  ASTM C 1036, Type I, Quality-Q3, Class I (clear) unless otherwise indicated. B. Ultraclear Float Glass:  ASTM C 1036, Type I, Quality-Q3, Class I, complying with other requirements specified and with visible light transmission not less than 91 percent. C. Heat-Treated Float Glass:  ASTM C 1048; Type I; Quality-Q3; Class I (clear) unless otherwise indicated; of kind and condition indicated. 1. Fabrication Process:  By horizontal (roller-hearth) process with roll-wave distortion parallel to bottom edge of glass as installed unless otherwise indicated. 2. For uncoated glass, comply with requirements for Condition A. 3. For coated vision glass, comply with requirements for Condition C (other coated glass). D. Polished Wired Glass:  ASTM C 1036, Type II, Class 1 (clear), Form 1, Quality-Q6, complying with ANSI Z97.1, Class C. UNIVERSITY of  NEW HAMPSHIRE    PLANNING, DESIGN AND CONSTRUCTION GUIDELINES January 25, 2013 CHAPTER 5 – TECHNICAL CONSTRUCTION AND RENOVATION STANDARDS GLAZING 08 8000 - 3 E. Film-Faced Polished Wired Glass:  ASTM C 1036, Type II, Class 1 (clear), Form 1, Quality-Q6 and complying with testing requirements in 16 CFR 1201 for Category II materials. F. Ceramic-Coated Vision Glass:  Heat-treated float glass, Condition C; with ceramic enamel applied by silk-screened process; complying with Specification No. 95-1-31 in GANA's Tempering Division's "Engineering Standards Manual" and with other requirements specified. G. On Drawings to identify where each color is required. Pyrolytic coatings may be used. 1.6 LAMINATED GLASS A. ASTM C 1172, and complying with testing requirements in 16 CFR 1201 for Category II materials, and with other requirements specified.  Use materials that have a proven record of no tendency to bubble, discolor, or lose physical and mechanical properties after fabrication and installation. 1. Construction:  Laminate glass with polyvinyl butyral interlayer or cast-in-place and cured-transparent-resin interlayer to comply with interlayer manufacturer's written recommendations. 2. Interlayer Thickness:  Provide thickness not less than that indicated and as needed to comply with requirements. 3. Interlayer Color:  Clear. 1.7 INSULATING GLASS A. Insulating-Glass Units:  Factory-assembled units consisting of sealed lites of glass separated by a dehydrated interspace, qualified according to ASTM E 2190, and complying with other requirements specified. 1.8 FIRE-PROTECTION-RATED GLAZING A. Fire-Protection-Rated Glazing, General:  Listed and labeled by a testing agency acceptable to authorities having jurisdiction, for fire-protection ratings indicated, based on testing according to NFPA 252 for door assemblies and NFPA 257 for window assemblies. B. Monolithic Ceramic Glazing:  Clear, ceramic flat glass; 3/16-inch (5-mm) nominal thickness. C. Film-Faced Ceramic Glazing:  Clear, ceramic flat glass; 3/16-inch (5-mm) nominal thickness; faced on one surface with a clear glazing film; complying with testing requirements in 16 CFR 1201 for Category II materials.
