Expand the character of your home or project by adding one of our divided lite options to your windows and doors. Choose
anything from a traditional, colonial-style pattern to a unique, custom design to accentuate the overall appearance of
your project. Kolbe offers four types of divided lites: grilles-in-the-airspace, wood removable grilles, performance divided
lites and true divided lites. As standard, wood bars have a beveled profile, however, an ovolo profile or a square profile
is also available.
(See pg. 192, Glazing Beads & Muntin Bars.)
Divided lite cross section drawings can be found on pgs. 180-181.
Kolbe’s performance divided lite (PDL) glazing
system gives the appearance of true divided
lites without sacrificing energy efficiency.
Extruded aluminum bars are adhered to the
exterior and unfinished pine bars are adhered to
the interior of the single lite of insulating glass.
Aesthetically pleasing spacer bars are installed
within the insulating glass unit. Together, these
bars create the illusion of true divided lites. PDL
bars are available in 5/8", 7/8", 1-1/8", 1-3/4",
2-1/4" or 4-1/2" bar widths. The exterior finish
of the aluminum bars will match the exterior
finish on the unit. Variations on the PDL option
may include custom grille patterns, custom bar
widths or no spacer bars. Some designs may
have a composite material for the exterior PDL
Performance Divided Lites
True divided lites (TDL) give each unit the
traditional look often found in historical projects.
Units with TDL are comprised of wood muntin
bars in between glass panes. The horizontal
and vertical, colonial-style wood TDL bars use
interlocking half-lap joints. Profile shadow lines
enhance the warm, richness of the wood on
both the interior and exterior. The exterior finish
on the bars will match the exterior finish of the
unit. TDL options include custom patterns and
bar widths, other wood species and interior
stain or paint finishes. Depending on glass
options chosen, standard bar widths are
available in 7/8" or 1-1/8". TDL glass units are
not filled with argon gas.
