DocuSign Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> SECTION 08 80 00-GLAZING <br /> PART 1 -GENERAL <br /> 1.1 SUMMARY <br /> A. This Section includes glazing for the following products and applications, including those specified in other Sections <br /> where glazing requirements are specified by reference to this Section: <br /> 1. Storefront framing. <br /> 1.2 DEFINITIONS <br /> A. Manufacturer:A firm that produces primary glass or fabricated glass as defined in referenced glazing publications. <br /> B. Interspace: Space between lites of an insulating-glass unit that contains dehydrated air or a specified gas. <br /> C. Deterioration of Insulating Glass: Failure of the hermetic seal under normal use that is attributed to the <br /> manufacturing process and not to causes other than glass breakage and practices for maintaining and cleaning <br /> insulating glass contrary to manufacturer's written instructions. Evidence of failure is the obstruction of vision by <br /> dust, moisture, or film on interior surfaces of glass. <br /> 1.3 PERFORMANCE REQUIREMENTS <br /> A. General: Provide glazing systems capable of withstanding normal thermal movement and wind and impact loads <br /> (where applicable) without failure, including loss or glass breakage attributable to the following: defective <br /> manufacture, fabrication, and installation; failure of sealants or gaskets to remain watertight and airtight; <br /> deterioration of glazing materials; or other defects in construction. <br /> B. Glass Design: Glass thicknesses indicated are minimums and are for detailing only. Confirm glass thicknesses by <br /> analyzing Project loads and in-service conditions. Provide glass lites for various size openings in nominal <br /> thicknesses indicated, but not less than thicknesses and in strengths (annealed or heat treated) required to meet or <br /> exceed the following criteria: <br /> 1. Glass Thicknesses: Select minimum glass thicknesses to comply with ASTM E 1300, according to the <br /> following requirements: <br /> a. Specified Design Wind Loads:As indicated. <br /> b. Probability of Breakage for Vertical Glazing: 8 lites per 1000 for lites set vertically or not more than 15 <br /> degrees off vertical and under wind action. <br /> 1) Load Duration: 60 seconds or less. <br /> c. Maximum Lateral Deflection: For the following types of glass supported on all four edges, provide <br /> thickness required that limits center deflection at design wind pressure to 1/50 times the short side length <br /> or 1 inch,whichever is less. <br /> 1) For insulating glass. <br /> d. Minimum Glass Thickness for Exterior Lites: Not less than 6 mm. <br /> C. Thermal Movements: Provide glazing that allows for thermal movements resulting from the following maximum <br /> change (range) in ambient and surface temperatures acting on glass framing members and glazing components. <br /> Base engineering calculation on surface temperatures of materials due to both solar heat gain and nighttime-sky <br /> heat loss. <br /> 1. Temperature Change (Range): 120 deg F, ambient; 180 deg F, material surfaces. <br /> D. Thermal and Optical Performance Properties: Provide glass with performance properties specified based on <br /> manufacturer's published test data, as determined according to procedures indicated below: <br /> 1. For insulating-glass units, properties are based on units with lites 6 mm thick and a nominal 1/2-inch- wide <br /> interspace. <br /> 2. Center-of-Glass U-Values: NFRC 100 methodology using LBL-35298 WINDOW 4.1 computer program, <br /> expressed as Btu/sq.ft.x h x deg F. <br /> 3. Center-of-Glass Solar Heat Gain Coefficient: NFRC 200 methodology using LBL-35298 WINDOW 4.1 <br /> computer program. <br /> 4. Solar Optical Properties: NFRC 300. <br /> 1.4 SUBMITTALS <br /> A. Product Data: For each glass product and glazing material indicated. <br /> B. Samples: For the following products, in the form of 12-inch-square Samples for glass. <br /> 1. Each type of insulated glass. <br /> C. Glazing Schedule: Use same designations indicated on Drawings for glazed openings in preparing a schedule <br /> listing glass types and thicknesses for each size opening and location. <br /> ©BOOMERANG DESIGN#1835 08 80 00-1 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 12/07/2018 <br />
