Series 5900 Inside Glazed Curtain Wall Installation Instructions
Section IX: Glazing
Glazing
A.) Clean all glazing pockets prior to glazing. This is necessary to avoid clogging the
weep system and staining the exterior metal and glass surfaces.
B.) Apply the preset glazing gaskets to the horizontal exterior glazing pockets.
FIG. 3
1.) Apply silicone sealant into the raceway a minimum of 2” each way at all corners
to the inside face of the glazing pocket. See FIG. 3
2.) Gaskets can become somewhat deformed during storage in cartons. The
gaskets should be removed from the cartons and / or rolls several hours prior
to use and laid flat or hung to allow for recovery of the correct shapes. The
temperature must be at least 50 degrees to allow this recovery.
3.) Cut vertical gaskets D.L.O. + 1 ¾”
4.) Cut horizontal gaskets D.L.O. + ½”
Note: If the exterior gaskets are
difficult to install into the
glazing race, a light coat of
mineral spirits may be
applied to the gasket.
