2.9 FABRICATION OF GLAZING UNITS
A. Fabricate glazing units in sizes required to fit openings indicated for Project, with edge and face
clearances, edge and surface conditions, and bite complying with written instructions of product
manufacturer and referenced glazing publications, to comply with system performance
requirements.
PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine framing, glazing channels, and stops, with Installer present, for compliance with the
following:
1. Manufacturing and installation tolerances, including those for size, squareness, and
offsets at corners.
2. Minimum required face and edge clearances.
3. Effective sealing between joints of glass-framing members.
B. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Clean glazing channels and other framing members receiving glass immediately before glazing.
Remove coatings not firmly bonded to substrates.
B. Examine glazing units to locate exterior and interior surfaces. Label or mark units as needed so
that exterior and interior surfaces are readily identifiable. Do not use materials that leave visible
marks in the completed Work.
3.3 GLAZING, GENERAL
A. Comply with combined written instructions of manufacturers of glass, sealants, gaskets, and
other glazing materials, unless more stringent requirements are indicated, including those in
referenced glazing publications.
B. Protect glass edges from damage during handling and installation. Remove damaged glass
from Project site and legally dispose of off Project site. Damaged glass includes glass with
edge damage or other imperfections that, when installed, could weaken glass, impair
performance, or impair appearance.
C. Apply primers to joint surfaces where required for adhesion of sealants, as determined by
preconstruction testing.
D. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing
publications, unless otherwise required by glass manufacturer. Set blocks in thin course of
compatible sealant suitable for heel bead.

glazing tapes are used that have demonstrated ability to maintain required face
clearances and to comply with system performance requirements.
2. Provide 1/8-inch- minimum bite of spacers on glass and use thickness equal to sealant
width. With glazing tape, use thickness slightly less than final compressed thickness of
tape.
F. Provide edge blocking where indicated or needed to prevent glass lites from moving sideways
in glazing channel, as recommended in writing by glass manufacturer and in accordance with
requirements in referenced glazing publications.
G. Set glass lites in each series with uniform pattern, draw, bow, and similar characteristics.
3.4 TAPE GLAZING
A. Position tapes on fixed stops so that, when compressed by glass, their exposed edges are flush
with or protrude slightly above sightline of stops.
B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to
make them fit opening.
C. Cover vertical framing joints by applying tapes to heads and sills first, then to jambs. Cover
horizontal framing joints by applying tapes to jambs, then to heads and sills.
D. Place joints in tapes at corners of opening with adjoining lengths butted together, not lapped.
Seal joints in tapes with compatible sealant approved by tape manufacturer.
E. Do not remove release paper from tape until right before each glazing unit is installed.
F. Center glass lites in openings on setting blocks, and press firmly against tape by inserting
dense compression gaskets formed and installed to lock in place against faces of removable
stops. Start gasket applications at corners and work toward centers of openings.
G. Apply cap bead of elastomeric sealant over exposed edge of tape.
3.5 SEALANT GLAZING (WET)
A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass
lites and glazing stops to maintain glass face clearances and to prevent sealant from extruding
into glass channel and blocking weep systems until sealants cure. Secure spacers or spacers
and backings in place and in position to control depth of installed sealant relative to edge
clearance for optimum sealant performance.
1. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or
bond of sealant to glass and channel surfaces.
2. Tool exposed surfaces of sealants to provide a substantial wash away from glass.
3.6 CLEANING AND PROTECTION
A. Immediately after installation, remove nonpermanent labels and clean surfaces.
B. Protect glass from contact with contaminating substances resulting from construction
operations. Examine glass surfaces adjacent to or below exterior concrete and other masonry

surfaces at frequent intervals during construction, but not less than once a month, for buildup of
dirt, scum, alkaline deposits, or stains.
1. If, despite such protection, contaminating substances do contact with glass, remove
substances immediately as recommended in writing by glass manufacturer. Remove and
replace glass that cannot be cleaned without damage to coatings.
C. Remove and replace glass that is damaged during construction period.
