Performance 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 wood bars 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.
When the weather turns frigid, LoE-180 glass is the
perfect cold remedy. It keeps homes warmer and more
comfortable by blocking heat loss to the outside and
letting the sun’s heat stream in to increase solar heat
Wherever glare is a problem, LoE²-240 glass is a solution
to maintain year-round comfort in warmer climates.
In summer, it blocks oppressive solar heat gain and
maintains cool glass temperatures. When winter rolls
around, it keeps inside glass temperatures warm.
LoE²-270 glass delivers year-round comfort in most
types of weather. Offering a balance of high clarity and
low solar heat gain, LoE
-270 is standard in most Kolbe
products. In summer, it rejects the sun’s heat and
damaging UV rays. In winter, it reflects heat back into the
For warm climates, LoE³-366 delivers a balance of solar
control and high visibility. This coating helps provide
protection of fading, blocking up to 95% of the sun’s
ThermaPlus LoE is an additional interior coating applied
to help meet the strictest energy requirements and
provide protection against heat loss and UV damage.
Triple-pane glass provides a greater energy performing
window that keeps indoor air warm and comfortable,
prevents heat loss and lowers your heating bills. Available
with a variety of LoE coatings that best suit your needs.

conditions, especially in coastal regions. Combined with
an impact product, such as K-Force

the highest level of security.
Harnesses the sun’s UV rays to loosen dirt so water can
rinse it away, leaving windows virtually spotless. A special
sputter-coating process makes the exterior glass surface
ultra smooth, so the water “sheets off” more readily than it
would on uncoated glass, allowing you to spend less time

individual glass panels. The exterior finish on the bars will
