Orange County Facility Renovations <br />Hillsborough, NC <br />Smith Sinnett GLAZING <br />2020046/2020047/2020048/2020049/2020055 08 80 00 - 8 <br />I. Set glass lites in each series with uniform pattern, draw, bow, and similar characteristics. <br /> <br /> <br />3.4 TAPE GLAZING <br /> <br />A. Position tapes on fixed stops so that, when compressed by glass, their exposed edges are flush with or <br />protrude slightly above sightline of stops. <br /> <br />B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to make <br />them fit opening. <br /> <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 /> <br />D. Place joints in tapes at corners of opening with adjoining lengths butted together, not lapped. Seal <br />joints in tapes with compatible sealant approved by tape manufacturer. <br /> <br />E. Do not remove release paper from tape until just before each glazing unit is installed. <br /> <br />F. Center glass lites in openings on setting blocks and press firmly against tape by inserting dense <br />compression gaskets formed and installed to lock in place against faces of removable stops. Start <br />gasket applications at corners and work toward centers of openings. <br /> <br />G. Apply cap bead of elastomeric sealant over exposed edge of tape. <br /> <br /> <br />3.5 GASKET GLAZING (DRY) <br /> <br />A. Fabricate compression gaskets in lengths recommended by gasket manufacturer to fit openings <br />exactly, with allowance for stretch during installation. <br /> <br />B. Insert soft compression gasket between glass and frame or fixed stop so it is securely in place with <br />joints miter cut and bonded together at corners. <br /> <br />C. Center glass lites in openings on setting blocks and press firmly against soft compression gasket by <br />inserting dense compression gaskets formed and installed to lock in place against faces of removable <br />stops. Start gasket applications at corners and work toward centers of openings. Compress gaskets to <br />produce a weathertight seal without developing bending stresses in glass. Seal gasket joints with <br />sealant recommended by gasket manufacturer. <br /> <br />D. Install gaskets so they protrude past face of glazing stops. <br /> <br /> <br />3.6 SEALANT GLAZING (WET) <br /> <br />A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass lites <br />and glazing stops to maintain glass face clearances and to prevent sealant from extruding into glass <br />channel and blocking weep systems until sealants cure. Secure spacers or spacers and backings in <br />place and in position to control depth of installed sealant relative to edge clearance for optimum <br />sealant performance. <br />B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or bond of <br />sealant to glass and channel surfaces. <br /> <br />C. Tool exposed surfaces of sealants to provide a substantial wash away from glass. <br /> <br /> <br />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
