shall be free of dirt, corrosion, residue, oils, and any other substance that may
impair adhesion of glazing materials.

.6
Do not perform glazing when ambient temperature is below 4 degrees Celsius
.7
Ensure humidity level is low before installation.
.8
Install glazing according to manufacturers’ specifications.
.9
Ensure space between double-glazing is perfectly clean before installing the
second panel.
General Glazing requirements:
.1
Comply with the general provisions of GANA Glazing Manual and the Ontario Building
Code for minimum glazing requirements, and ensure that minimum frame lap (minimum
grip of glass) and edge clearances are provided as required for the size of openings.
Provide for expansion and contraction of glass as required.
.2
Conform with the manufacturers’ latest published installation instructions and
recommendations for glazing of tempered glass, wired glass, laminated glass, and
insulating glass. Follow manufacturer’s latest published instructions for protection of
edges and sizing of glass.
.3
Install glass in fire rated assemblies in accordance with NFPA 80.
.4
Provide setting blocks at quarter points along the bottom of the glass pane. Blocks shall
support the glass 1.5875 mm above the metal. Provide spacers to hold glass in centre
between stops.
.5
Provide spacers for glass panes where length plus width is greater than 1270 mm
.1
Locate spacers directly opposite each other on both inside and outside faces of
the glass. Install correct size of spacers and spacing to preserve required face
clearances, unless gaskets and glazing tapes are used that have demonstrated
ability to maintain required face clearances and to comply with system
performance requirements.
.2
Provide 3.2 mm minimum bite of spacers on glass and use thickness equal to
sealant width.
.6
Adjust glazing channel dimensions as required by conditions during installation to provide
necessary bite on glass, minimum edge and face clearances, and adequate sealant
thicknesses, with reasonable tolerances.
.7
Protect glass edges from damage during handling and installation. Remove damaged
glass from project site and dispose in accordance with municipal waste management and
recycling requirements. Glass is considered to be damaged if edge damage, or other
imperfections that, when installed, could weaken the glass and impair performance and/or
appearance.

Glazing of hollow metal doors and frames: glass shall be set around all edges with glazing
gaskets hereinbefore specified. Provide setting blocks and spacers blocks as required.
Set gasket legs on both sides of glass. Gasket shall be continuous, notched only at top
rail in the centre. Compress gasket at least 15 percent to form a tight seal.
.9
For indoor glass panels: - set glass panes with proper orientation so that coating faces the
correct specified direction
.10
For Hollow Metal Doors: specified in Section 8 11 00. Install 6 mm fire rated glass unless
indicated otherwise. Fixed stop bedding, glazing tape, removable stops, and glazing tape.
Tape Glazing:
.1
Position tapes on fixed stops so that, when compressed by the glass, their exposed edges
are flush with or protrude slightly above sightline of stops.
.2
Install tapes continuously, but not necessarily in one continuous length. Do not stretch
tapes to make them fit opening.
.3
Cover vertical framing joints by applying tapes to heads and sills first and then to jambs.
Cover horizontal framing joints by applying tapes to jambs and then to heads and sills.
.4
Follow tape glazing manufacturers documented instructions for application.

Installation of Mirrors
.1
Mount unframed mirrors in true planes, free of distortions. Surfaces of butted mirrors shall
be flush to < 1 mm. Mirror installation shall be flat to within 1.5 mm in 1220 mm
.2
Generally, joints in mirrors are acceptable only for locations where mirrors are longer than
3050 mm (10’). Provide butt joints with ground and polished edges. Apply 6 mm wide
clear silicone at butt joints.
.3
Mastic adhesive and bottom trim support installation:
.1
Mirror substrate shall be free of dust, clean and dry. On nonporous substrates,
such as glass, tile, or metal, sealing is not necessary. On porous substrates,
such as gypsum board or wood, use Mirro-Mastic Bond on the substrates and
allow it to dry.
2011-09-21
.2
Support mirror at the bottom aluminium trim and shim at ¼ points with concealed
setting blocks
.3
Apply mirror adhesive to the mirror or substrate in a minimum of 1 golf ball size
mound for every 0.0929 m2 of mirror. Do not apply mastic too close to the edge
to prevent “squeeze out”.

Place the mounds so space will be left between them when mirror is installed.
Mastic adhesive shall be at room temperature (22C).
.5
Press mirror firmly in place making good contact between the mirror, mastic, and
substrate.
.6
Mastic should spread to a pat approximately 114 mm in diameter. The mastic
needs air circulation to cure properly.

Curing time will depend on temperature, humidity, type of substrate, and amount
of air that can reach the mastic.
