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.

Divided Lites

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.
