Kolbe offers glazing options to address the optimum energy efficiency
of the overall window unit for the geographic region in which you live.
As standard, we use double strength annealed glass in most units, with
double-pane insulating LoE
-270 glass. LoE is a “smart” coating that
reduces energy transfer through the insulating glass unit. LoE coated
glass is also designed to reflect room-side heat back into the room during
winter months. In summer, visible sunlight is allowed in while blocking
96% of the sun’s infrared heat energy. The result is significant savings on
heating and cooling costs throughout the year. LoE coatings also reduce
the potential for condensation, as well as provide protection against
fading of furniture, fabrics and carpeting. Along with LoE coatings,
standard glass is filled with argon gas*, which has a 30% lower thermal
conductivity than that of air.
Kolbe also offers the following glass options, as well as many
A tinted glass recommended for warm climates that achieves solar control over a wide range of the spectrum, while also
helping to reduce glare.
Offers an ideal balance of solar control and high visibility by blocking 95% of UV rays while maintaining the interior
Helps to meet the strictest energy requirements; provides protection against heat loss and UV damage.
Mountain Air Energy Package
Specifically designed to meet a U-factor of .30 without argon gas. Consists of a specially-constructed frame, second-
generation ThermaPlus glass with LoE³-366 and a high altitude tube within the insulating glass unit. Available on Crank-
Out Casements and Awnings, Sterling Double Hungs, and Studio/Picture, Transom and Direct Set units to match Crank-
Out Casements and Sterling Double Hungs.
Provides a greater energy performing window that keeps indoor air warm and comfortable, prevents heat loss and
lowers your heating bills. It is constructed with three panes of glass, argon gas, Thermo-Edge spacer bars and is
available with a variety of LoE coatings that best suit your needs.
Tinted, Colored or Patterned
Provides shading, privacy or visual interest.
Finely Crafted Glass
Decorative glass created with a variety of caming options.
Standard in Kolbe doors to address safety concerns. Also available in window units to meet specific building codes.
Benefits include safety, security, sound control and provides the ultimate in UV blockage.
Glazing utilized to withstand harsh environmental conditions, especially in coastal regions. Combined with an impact
product, such as K-Force
, this product offers the highest level of security.
A protective film that protects the glass surfaces from scratches during transit and construction,
as well as reducing the time involved in job site clean-up.
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 glass ultra smooth, so the water “sheets off”
more readily than it would on uncoated glass, allowing you to spend less time cleaning.
* Argon gas may not be included with units to be installed in or shipped through high altitude areas. Units with true divided lites may not include argon gas.
Not all glass is available on all series. Please contact your Kolbe dealer for product specifics.
