Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />GLAZING <br />08 80 00 - 11 <br /> <br /> <br />J. Where wedge-shaped gaskets are driven into one side of channel to pressurize <br />sealant or gasket on opposite side, provide adequate anchorage so gasket cannot <br />walk out when installation is subjected to movement. <br />K. Square cut wedge-shaped gaskets at corners and install gaskets in a manner <br />recommended by gasket manufacturer to prevent corners from pulling away; seal <br />corner joints and butt joints with sealant recommended by gasket manufacturer. <br />3.4 GASKET GLAZING (DRY) <br />A. Fabricate compression gaskets in lengths recommended by gasket manufacturer to <br />fit openings exactly, with allowance for stretch during installation. <br />B. Insert soft compression gasket between glass and frame or fixed stop so it is <br />securely in place with joints miter cut and bonded together at corners. <br />C. Center glass lites in openings on setting blocks and press firmly against soft <br />compression gasket by inserting dense compression gaskets formed and installed to <br />lock in place against faces of removable stops. Start gasket applications at corners <br />and work toward centers of openings. Compress gaskets to produce a weathertight <br />seal without developing bending stresses in glass. Seal gasket joints with sealant <br />recommended by gasket manufacturer. <br />D. Install gaskets so they protrude past face of glazing stops. <br />3.5 SEALANT GLAZING (WET) <br />A. Install continuous spacers, or spacers combined with cylindrical sealant backing, <br />between glass lites and glazing stops to maintain glass face clearances and to <br />prevent sealant from extruding into glass channel and blocking weep systems until <br />sealants cure. Secure spacers or spacers and backings in place and in position to <br />control depth of installed sealant relative to edge clearance for optimum sealant <br />performance. <br />B. Force sealants into glazing channels to eliminate voids and to ensure complete <br />wetting or bond of sealant to glass and channel surfaces. <br />C. Tool exposed surfaces of sealants to provide a substantial wash away from glass. <br />3.6 CLEANING AND PROTECTION <br />A. Protect exterior glass from damage immediately after installation by attaching <br />crossed streamers to framing held away from glass. Do not apply markers to glass <br />surface. Remove nonpermanent labels, and clean surfaces. <br />B. Protect glass from contact with contaminating substances resulting from <br />construction operations, including weld splatter. If, despite such protection, <br />contaminating substances do come into contact with glass, remove substances <br />immediately as recommended by glass manufacturer.
