Most of the extrusions in this system are the same, only the
sill and its anchors are different. Note that the tapes used
for sealing the horizontals to mullions are located in a differ-
ent manner.
The sill is designed so that sill anchors may be cap sealed
before the frame is installed. The frame is installed over the
the sill with twist-in anchors. This prevents any additional
screws from penetrating the sill and causing leaks under the
sill.
Multiple units require the use of split mullions. A minimum of
7/16" clearance between the jamb and sill end dam must be
provided. This will allow a minimum of 3/8" clearance to
move first unit sideways so the second unit with the same
clearance will clear the interlocking legs of the expansion
mull. Adjust frame locations before running perimeter seals.
OBE recommends using FG-2188 vinyl filler to improve
the perimeter seal.
OBE does not recommend the shear block or stack
method of assembly for inside glazing.
