Kolbe’s standard glass offerings are complemented by a state-of–the-art, stainless steel spacer bar system on most
units. The advanced design of this system incorporates a stainless steel spacer with airtight bent corners and a dual-
seal construction of compressed polyisobutylene (PIB) and silicone. Desiccants are contained in the spacer to eliminate
the potential for moisture. These features combine to reduce the thermal
transmission through the edge seal, creating better energy performance and
increasing the roomside glass temperature while reducing the potential for
condensation at the sash to glass interface as compared to aluminum spacer
designs. Thermo-Edge spacers are one of the many quality details that define
Kolbe windows and doors. Thermo-Edge spacers are not available on very
small radius units, units with ½" insulated glass, with the champagne or dark
Bronze Anodized spacer option, units with “pencil” bar grilles-in-the-airspace,
or true divided lites. Available in stainless steel (standard) and black painted.
Additional Glass Options
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.
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 capillary/breather
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.
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.
Tinted, Colored or Patterned
Provides shading, privacy or visual interest.
Finely Crafted Glass
(not available with argon gas)
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.
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 cleaning.
NOTE: Not all glass is available on all products. Please contact your Kolbe dealer for product specifics.

LoE insulating glass with a stainless steel spacer bar carries a 20-year warranty. Not all glass options listed have the same glass
warranty. Please contact your dealer for details.
Inert gas dissipates over the life of the insulated glass unit. Kolbe does not warrant the amount or percentage of argon
present in insulating glass or a specific level of unit thermal efficiency at any time after manufacture. Visit the energy data
section of our website at kolbe-kolbe.com to select and view your specific window and its listed energy performance values.
