PASSMORE CENTER ADDITION AND RENOVATION <br />HILLSBOROUGH, NORTH CAROLINA <br />other imperfections that, when installed, could weaken glass and impair performance and <br />appearance. <br />D. Apply primers to joint surfaces where required for adhesion of sealants, as determined by <br />preconstruction sealant - substrate testing. <br />E. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing <br />publications, unless otherwise required by glass manufacturer. Set blocks in thin course of <br />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 length plus width is larger than 50 inches (1270 mm) as <br />follows: <br />1. Locate spacers directly opposite each other on both inside and outside faces of glass. <br />Install correct size and spacing to preserve required face clearances, unless gaskets and <br />glazing tapes are used that have demonstrated ability to maintain required face clearances <br />and to comply with system performance requirements. <br />2. Provide 1/8 -inch (3 -mm) minimum bite of spacers on glass and use thickness equal to <br />sealant width. With glazing tape, use thickness slightly less than final compressed <br />thickness of tape. <br />H. Provide edge blocking where indicated or needed to prevent glass lites from moving sideways <br />in glazing channel, as recommended in writing by glass manufacturer and according to <br />requirements in referenced glazing publications. <br />I. Set glass lites in each series with uniform pattern, draw, bow, and similar characteristics. <br />3.4 TAPE GLAZING <br />A. Position tapes on fixed stops so that, when compressed by glass, their exposed edges are flush <br />with or protrude slightly above sightline of stops. <br />B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to <br />make them fit opening. <br />C. Cover vertical framing joints by applying tapes to heads and sills first and then to jambs. Cover <br />horizontal framing joints by applying tapes to jambs and then to heads and sills. <br />D. Place joints in tapes at corners of opening with adjoining lengths butted together, not lapped. <br />Seal joints in tapes with compatible sealant approved by tape manufacturer. <br />E. Do not remove release paper from tape until just before each glazing unit is installed. <br />F. Apply heel bead of elastomeric sealant. <br />GLAZING 088000- 12 <br />
