3.
Measure both the vertical and horizontal dimensions
of the glass and the panel opening. Subtract the
vertical glass size from the vertical panel opening
size. Divide the difference by two. This will give the
nominal thickness of the setting block to use at
the
top and bottom rails. Several setting blocks of
different thickness may need to be combined to
obtain the desired thickness. Do the same for the
horizontal dimension to obtain the thickness of the
setting block to use at the stiles.
4.
Place a setting block (or combination of setting
blocks with desired thickness) on the bottom rail of
the panel opening such that it is about 2
"
from
the bottom corner as determined by the bracing
rules above.
5.
Carefully place the glass in the opening, making
sure
it rests on the setting block. With insulated
glass,
make sure that both inner and outer panes are
supported evenly.
6.
Place a second setting block in the same corner as
the first setting block, but in the vertical direction
along the stile such that it is about 2
"
above the
corner.
7.
Place another setting block in the upper diagonal
corner vertically on the opposite stile in the same
manner. If necessary, apply a little adhesive that is
non-damaging to the glass edge seals such as Dow
Corning 791 silicone, to keep the vertical setting
blocks from slipping.
8.
Place the last setting block on the upper rail on the
same corner as the other upper setting block. To get
a proper fit, shift the glass weight by lifting the panel
up with a plastic pry bar at the lower corner below
the upper setting block. These setting blocks should
all fit snugly but should not be forced.
Adjust the
thickness of the glass setting blocks such
that the
panel is slightly out of square. The upper
corner with
the setting blocks should be about 1/16
"
higher than
the other corner.
If the panels are large, additional setting blocks may
be needed midpoint on the stiles, especially on a
swing panel.
9. For aluminum systems insert the glass stops so that
they snap into the panel profile. For wood systems
insert the glass stop firmly into position, so they are
flush with the panel. Nail to the inner side of the panel
with small finish nails. Start with the top and bottom
stops and then the sides.
10. Insert the glazing gasket in the space between the
glass and the glass stop. First, cut the gasket to a
length a little longer than the actual length of the
glass stop because gasket material may shrink at low
temperatures. Do not stretch or pull the gasket in any
manner. If necessary, use soapy water to lubricate the
gasket to make insertion easier.
11. Make sure that the stops are locked firmly and
securely into position and are flush with the rest of
the panel profile.
12. Repeat Steps 2 to 12 for each of the other panels.
Setting blocks for each succeeding panel must be
placed at diagonally opposite corners in the proper
sequence as set forth in Step 1. See Diagram 1 for an
example of a three panel unit.
