GLAZING
8.1
Note: To avoid sealant 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 set glass in each opening. Install
exterior gaskets:
Type A installation (verticals running through) − Gaskets at all verticals run through; head, sill
and intermediate horizontal gaskets butt into the vertical gaskets.
Type B installation (head/sill running through) − Gaskets at all head and sill members run
through; vertical gaskets butt into the head and sill gaskets. At intermediate horizontals, the
vertical gaskets run through.
Crowd the gaskets into the corners, cutting the horizontal gaskets at an angle to
match the bevel on adjoining gaskets. Gaskets should be removed from the roll and allowed
to relax overnight before cutting. Cut all gaskets to D.L.O. plus 1/4" per foot of aluminum extrusion.
Seal joint between the corners of the gaskets just prior to glazing; seal all exterior corners.
8.2
Position setting blocks at correct location (two per lite). Refer to approved shop drawings or
deadload charts for locations. Stake the hooks on both sides of setting chair at sill. Lubrication
on the top of the setting block will help insure proper setting for lites of glass.
8.3
Set glass in opening. Ensure that glass bite is equal on all sides.
for glazing sequence.
Start glazing the frame from bottom and work up.
GLASS SIZE CALCULATION:
D.L.O. + 1" FOR WIDTH & HEIGHT at CAPTURED SYSTEM

D.L.O. + 1" at CORNER MULLIONS (CAPTURED)
