DocuSign Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> SECTION 08 80 00 -GLAZING <br /> 3. Thermoplastic polyolefin rubber. <br /> 4. Any material indicated above. <br /> 2.5 MISCELLANEOUS GLAZING MATERIALS <br /> A. General: Provide products of material, size, and shape complying with referenced glazing standard, requirements of <br /> manufacturers of glass and other glazing materials for application indicated, and with a proven record of <br /> compatibility with surfaces contacted in installation. <br /> B. Cleaners, Primers, and Sealers:Types recommended by sealant or gasket manufacturer. <br /> C. Setting Blocks: Elastomeric material with a Shore A durometer hardness of 85, plus or minus 5. <br /> D. Spacers: Elastomeric blocks or continuous extrusions with a Shore A durometer hardness required by glass <br /> manufacturer to maintain glass lites in place for installation indicated. <br /> E. Edge Blocks: Elastomeric material of hardness needed to limit glass lateral movement(side walking). <br /> F. Cylindrical Glazing Sealant Backing: ASTM C 1330, Type O (open-cell material), of size and density to control <br /> glazing sealant depth and otherwise produce optimum glazing sealant performance. <br /> 2.6 FABRICATION OF GLASS AND OTHER GLAZING PRODUCTS <br /> A. Fabricate glass and other glazing products in sizes required to glaze openings indicated for Project, with edge and <br /> face clearances, edge and surface conditions, and bite complying with written instructions of product manufacturer <br /> and referenced glazing standard,to comply with system performance requirements. <br /> B. Clean-cut or flat-grind vertical edges of butt-glazed monolithic lites in a manner that produces square edges with <br /> slight kerfs at junctions with indoor and outdoor faces. <br /> C. Grind smooth and polish exposed glass edges. <br /> PART 3-EXECUTION <br /> 3.1 EXAMINATION <br /> A. Examine framing glazing,with Installer present,for compliance with the following: <br /> 1. Manufacturing and installation tolerances, including those for size, squareness, and offsets at corners. <br /> 2. Presence and functioning of weep system. <br /> 3. Minimum required face or edge clearances. <br /> 4. Effective sealing between joints of glass-framing members. <br /> B. Proceed with installation only after unsatisfactory conditions have been corrected. <br /> 3.2 PREPARATION <br /> A. Clean glazing channels and other framing members receiving glass immediately before glazing. Remove coatings <br /> not firmly bonded to substrates. <br /> 3.3 GLAZING, GENERAL <br /> A. Comply with combined written instructions of manufacturers of glass, sealants, gaskets, and other glazing <br /> materials, unless more stringent requirements are indicated, including those in referenced glazing publications. <br /> B. Glazing channel dimensions, as indicated on Drawings, provide necessary bite on glass, minimum edge and face <br /> clearances, and adequate sealant thicknesses,with reasonable tolerances.Adjust as required by Project conditions <br /> during installation. <br /> C. Protect glass edges from damage during handling and installation. Remove damaged glass from Project site and <br /> legally dispose of off Project site. Damaged glass is glass with edge damage or other imperfections that, when <br /> installed, could weaken glass and impair performance and appearance. <br /> D. Apply primers to joint surfaces where required for adhesion of sealants, as determined by preconstruction sealant- <br /> substrate testing. <br /> E. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing publications, unless <br /> otherwise required by glass manufacturer. Set blocks in thin course of compatible sealant suitable for heel bead. <br /> F. Do not exceed edge pressures stipulated by glass manufacturers for installing glass lites. <br /> G. Provide spacers for glass lites where the length plus width is larger than 50 inches as follows: <br /> 1. Locate spacers directly opposite each other on both inside and outside faces of glass. Install correct size and <br /> spacing to preserve required face clearances, unless gaskets and glazing tapes are used that have <br /> ©BOOMERANG DESIGN#1835 08 80 00-4 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 12/07/2018 <br />
