Kolbe Windows

Kolbe builds premium-quality casement and awning windows, double and single hungs, sliding windows, as well as bays and bows. We offer direct set windows, stand-alone radius windows, operating windows with radius tops, and geometric shapes. We even offer convenient folding windows.


Casements open easily from the side and provide excellent ventilation. They are energy efficient because they seal tightly to the frame when closed, which prevents air infiltration.

Folding Windows

Folding windows create expansive openings and are available in many operational configurations. They use the same basic hardware as folding doors and provide a graceful pass-through to the outdoors.

Sliding Windows

Sliding windows are windows with two or three sash which slide horizontally to operate. This makes them popular for use in tight spaces. In some cases, the sash can be removed for cleaning from the indoors.


Awnings open at the bottom, for ventilation even in mist or light rain. When closed, effective weather-stripping helps create a tight and efficient seal.

Direct Sets

Direct Sets are designed for projects that do not require operating windows. The glass is set directly into the frame, maximizing the viewing area and allowing a great deal of daylight into a room.


Radius windows are available as stand-alone full-circles and ovals. Half-circles, quarter-circles and ellipticals can be installed as stand-alone units or stacked and mulled with other windows.

Double Hungs

Double hung windows have two sash – one above the other – that operate by sliding up and down. Double hungs offer a cottage-type atmosphere and are often embellished with divided lites.

Corner Windows

Corner windows in a variety of degrees allow expansive views, with a crisp, contemporary aesthetic.


Geometric windows are available in a wide variety of shapes. They can be stand-alone units or they can be mulled and/or stacked with other windows to create unique configurations.
