3.1 EXAMIlVATION <br /> A Do not proceed with glazing until uusatisfactory conditions have been corrected. <br /> 3.2 PREPARATION <br /> A. Clean glazing channels and other framing members receiving glass immediately before <br /> �lazing. Remove coatings that are not firmly bonded to substrates. <br /> 3.3 GLAZING,GENERAL <br /> A. Comply with combined recommendations of manufacturers of glass,sealants,gaskets,and <br /> other glazing materials, except where more stringent requirements are indicated, including those in referenced <br /> glazing publications. <br /> B. Glazing channel dimensions as iridicated on Drawings provide necessary bite on glass, <br /> minimum edge and face clearances, and adequate sealant thiclrnesses, with reasonable tolerances. Adjust as <br /> required by Project conditions during installation. <br /> C. Protect glass from edge damage during handling and installation as follows: <br /> 1. Use a rolling block in rotating glass units to prevent damage to glass comers. Do not impact glass <br /> with metal fraaning. Use suction cups to shift glass units within openings;da not raise or drift <br /> glass with a pry bar. Rotate glass lites with flares or bevels on bottom horizontal edges so edges <br /> are located at top of opening,unless otherwise indicated by manufachuer's label. <br /> 2. Remove damaged glass from Project site and legally dispose of off site. Damaged glass is glass <br /> with edge damage or other imperfections that, when installed, weaken glass and impair <br /> performance and appearance. <br /> D. Apply primers to joint surfa�es where required for adhesion of sealants,as determined by <br /> preconstruction sealant-substrate testing. <br /> E. Install elastomeric setting blocks in sill rabbets,sized and located to comply with referenced <br /> glazing standard,unless otherwise required by glass manufacturer. Set blocks in thin course of compatible sealant <br /> suitable fon c�el bead. <br /> F. Do not exceed edge pressures stipulated by glass manufacturers fnr installiug glass lites. <br /> G. Provide spacers for glass sizes larger than 50 united inches(length plus height)as follows: <br /> 1. Locate spacers inside,outside,and directly opposite each other. Install conect size and spacing <br /> to preserve required face clearances,except where gaskets and glazing tapes are used that have <br /> demonstrated ability to maintain required face clearances and comply with system performance <br /> requirements. <br /> 2. Provide 1/8-inch minimum bite of spacers on glass and use thiclrness equal to sealant width. With <br /> glazing tape,use thickness slightly Iess than final compressed thickness of tape. <br /> H. Provide edge blocking to comply with requirements of referenced glazing publications, <br /> unless otherwise required by glass manufactiu�er. <br /> I. Set glass lites in each series with uniform pattern,draw,bow,and similar characteristics. <br /> J. Where wedge-shaped gaskets are driven into one side of channel to pressurize sealant or <br /> gasket on opposite sid�,provide adequate anchordge so gasket cannot walk out when installation is subjected to <br /> movement. <br /> K. Square cut wedge-shaped gaskets at corners and install gaskets in manner recommended by <br /> gasket manufacturer to prevent comers from pulling away; seal corner joints and butt joints with sealant <br /> recommended by�asket manufacturer. <br /> Page 6 of 8 <br />
