3.3 Note: To avoid silicone curing before glass is set in place and contamination from job-site debris,
glazing prep must be done as each opening is glazed. Do not pre-seal the gaskets in the entire frame; install
and seal gaskets as you are ready to set glass in each opening. Install interior gaskets into backmembers, both
horizontal and vertical, installing vertical gaskets first. If the vertical mullion is spliced, run gasket through the splice
joint, setting gasket in fresh silicone at splice joint, trimming the gasket dart as necessary to form an airtight seal.
Glazing gaskets at verticals run through; horizontal gaskets butt into vertical gaskets. Crowd the gaskets into corners,
cutting the horizontal gaskets at an angle to match bevel on vertical gaskets. Pulling the horizontal gasket back, seal
joint between the corners of the gaskets just prior to setting the glass. Release the gasket back to its original position,
making sure sealant fills the entire joint. Tool corner joints after glass is set and temporary glazing retainers are
installed.
NOTE: Sealant is not required at the horizontal gasket abutting an SSG mullion. This gap will be sealed during
application of structural silicone.
3.4 Position setting blocks at correct location (two per lite). Refer to approved shop drawings or dead load charts.
Lubricating the bottom of setting block will assist in proper setting of glass.Consult glass manufacturer for correct
setting block location and length for glass sizes in excess of 40 sq. ft, and recommended lubricants.
Thermal isolator
3.1 Install face gaskets into all horizontal pressure plates. Crowd all gaskets into members to avoid relaxation of
material. See page 8 for gasket cut length information.
3.2 Install thermal isolator into groove on face of horizontal and vertical mullion tongues. Vertical isolators are cut
mull length. Horizontal isolators are cut D.L.O. minus 1/4". SEE FIGURE 17.
