GLAZING 08 80 00 - 7 <br />Orange County Architectural Renovations Smith Sinnett / 2023036 <br />Hillsborough, NC Orange County Asset Management Services <br /> <br />PART 3 - EXECUTION <br /> <br /> <br />3.1 EXAMINATION <br /> <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 <br />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 /> <br />B. Proceed with installation only after unsatisfactory conditions have been corrected. <br /> <br /> <br />3.2 PREPARATION <br /> <br />A. Clean glazing channels and other framing members receiving glass immediately before glazing. <br />Remove coatings not firmly bonded to substrates. <br /> <br /> <br />3.3 GLAZING, GENERAL <br /> <br />A. Comply with combined written instructions of manufacturers of glass, sealants, gaskets, and other <br />glazing materials, unless more stringent requirements are indicated, including those in referenced <br />glazing publications. <br /> <br />B. Glazing channel dimensions, as indicated on Drawings, provide necessary bite on glass, minimum edge <br />and face clearances, and adequate sealant thicknesses, with reasonable tolerances. Adjust as required <br />by Project conditions during installation. <br /> <br />C. Protect glass edges from damage during handling and installation. Remove damaged glass from Project <br />site and legally dispose of off Project site. Damaged glass is glass with edge damage or other <br />imperfections that, when installed, could weaken glass and impair performance and appearance. <br /> <br />D. Apply primers to joint surfaces where required for adhesion of sealants, as determined by <br />preconstruction sealant-substrate testing. <br /> <br />E. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing publications, <br />unless otherwise required by glass manufacturer. Set blocks in thin course of compatible sealant suitable <br />for heel bead. <br /> <br />F. Do not exceed edge pressures stipulated by glass manufacturers for installing glass lites. <br /> <br />G. Provide spacers for glass lites where 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 <br />correct size and spacing to preserve required face clearances, unless gaskets and glazing tapes <br />are used that have demonstrated ability to maintain required face clearances and to comply with <br />system performance requirements. <br />a. Provide 1/8-inch minimum bite of spacers on glass and use thickness equal to sealant <br />width. With glazing tape, use thickness slightly less than final compressed thickness of <br />tape. <br />H. Provide edge blocking where indicated or needed to prevent glass lites from moving sideways in glazing <br />channel, as recommended in writing by glass manufacturer and according to requirements in referenced <br />glazing publications. <br />Docusign Envelope ID: 52FACC74-DA96-491B-B0B8-04AC3961737D
