DocuSign Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> SECTION 08 80 00 -GLAZING <br /> demonstrated ability to maintain required face clearances and to comply with system performance <br /> requirements. <br /> 2. Provide 1/8-inch minimum bite of spacers on glass and use thickness equal to sealant width. With glazing <br /> tape, use thickness slightly less than final compressed thickness of tape. <br /> H. Provide edge blocking where indicated or needed to prevent glass lites from moving sideways in glazing channel, <br /> as recommended in writing by glass manufacturer and according to requirements in referenced glazing <br /> publications. <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 gasket on opposite side, <br /> provide adequate anchorage so gasket cannot walk out when installation is subjected to movement. <br /> K. Square cut wedge-shaped gaskets at corners and install gaskets in a manner recommended by gasket <br /> manufacturer to prevent corners from pulling away; seal corner joints and butt joints with sealant recommended by <br /> gasket manufacturer. <br /> 3.4 TAPE GLAZING <br /> A. Position tapes on fixed stops so that, when compressed by glass, their exposed edges are flush with or protrude <br /> slightly above sightline of stops. <br /> B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to make them fit <br /> opening. <br /> C. Where framing joints are vertical, cover these joints by applying tapes to heads and sills first and then to jambs. <br /> Where framing joints are horizontal, cover these 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. Seal joints in tapes <br /> 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 /> G. Center glass lites in openings on setting blocks and press firmly against tape by inserting dense compression <br /> gaskets formed and installed to lock in place against faces of removable stops. Start gasket applications at corners <br /> and work toward centers of openings. <br /> H. Apply cap bead of elastomeric sealant over exposed edge of tape. <br /> 3.5 GASKET GLAZING (DRY) <br /> A. Fabricate compression gaskets in lengths recommended by gasket manufacturer to fit openings exactly, with <br /> stretch allowance during installation. <br /> B. Insert soft compression gasket between glass and frame or fixed stop so it is securely in place with joints miter cut <br /> and bonded together at corners. <br /> C. Center glass lites in openings on setting blocks and press firmly against soft compression gasket by inserting dense <br /> compression gaskets formed and installed to lock in place against faces of removable stops. Start gasket <br /> applications at corners and work toward centers of openings. Compress gaskets to produce a weathertight seal <br /> without developing bending stresses in glass. Seal gasket joints with sealant recommended by gasket <br /> manufacturer. <br /> D. Install gaskets so they protrude past face of glazing stops. <br /> 3.6 SEALANT GLAZING (WET) <br /> A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass lites and glazing <br /> stops to maintain glass face clearances and to prevent sealant from extruding into glass channel and blocking weep <br /> systems until sealants cure. Secure spacers or spacers and backings in place and in position to control depth of <br /> installed sealant relative to edge clearance for optimum sealant performance. <br /> B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or bond of sealant to glass <br /> and channel surfaces. <br /> C. Tool exposed surfaces of sealants to provide a substantial wash away from glass. <br /> 3.7 PROTECTION AND CLEANING <br /> A. Protect exterior glass from damage immediately after installation by attaching crossed streamers to framing held <br /> away from glass. Do not apply markers to glass surface. Remove nonpermanent labels, and clean surfaces. <br /> ©BOOMERANG DESIGN#1835 08 80 00-5 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 12/07/2018 <br />
