Most of the extrusions in this system are the same,
only the sill and its anchors are different. Notice
also, that the tapes used for sealing the horizontals
to mullions are located in a different manner.
The sill is designed so that the sill anchors may be
cap sealed before the frame is installed. The frame
is installed over the sill twist-in anchors. This pre-
vents 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 provide a
minimum of 3/8" clearance to move first unit side-
ways to the second unit with the same clearance
will clear interlocking legs of the expansion mull.
Adjust frame locations before running perimeter
seals. Oldcastle BuildingEnvelope recommends using
FG-2188 vinyl filler to improve the perimeter seal.
