Company History

Kolbe Windows and Doors excel on the legacy of Herb and Ervin Kolbe, two brothers who began a humble business of repairing and building windows and door frames. Their little shop started in 1946 in Marathon, Wisconsin, and continued to grow thanks to their hard work and steadfastness. 

Today, over seven decades later, Kolbe is a nationally recognized leader in the window and door industry. Their broad range of quality products is available through hundreds of retailers across the United States, Canada, and further. While the business has outlived its founding members, the sense of family and commitment to their local employees still holds. Kolbe is now run by Judi Gorski, the daughter of Herb Kolbe, and Jeff De Lonay, who started as a factory worker over 30 years ago and worked his way up as he gained hands-on training with the business.

Product Lines & Styles

Kolbe offers four product lines including the VistaLuxe Collection, Forgent Series, Ultra Series, and Heritage series.  Each line of windows is designed to meet specific architectural needs and have a wide range of customizable options. 

VistaLuxe Collection

The Vistaluxe Collection features a contemporary look for homes with a modern aesthetic. Kolbe describes this series as utilizing clean lines and large expanses of glass. All of the windows in the VistaLuxe Collection are available for new construction applications. There are two sublines in this collection. VistaLuxe WD is the original collection and made with extruded aluminum exteriors and warm wood exteriors. The VistaLuxe AL Line is all aluminum. 

The WD line is available in two profile styles. The Flush profile provides a stream-line look and the sash in the same plane as the frame. The Accent profile adds visual interest by recessing the sash. This creates a shadow line effect while keeping the sash in the same plane as the frame. When painted in a darker color, the frames simulate the look of steel. The WD line promises better efficiency, lower cost, and shorter lead times. Both profiles are available with double and triple pane glass. 

The WD line is available in the following styles:

  • Casement
  • Awning
  • Sliding
  • Specialty

The AL line is all aluminum and thermally broken, meaning that high-performance insulator material separates where the metal parts join. It prevents heat from exiting the home by traveling from the interior to the exterior by following a connected bridge or path between the inside and outside of the window frame. Aesthetically, the windows emphasize clean lines and coordinated profiles. This series is available in four powder-coated and two anodized finishes for both the interior and exterior. Square interiors and exteriors for a sleek design, European-style hardware, and large expanses of glass. 

The AL line is available in three styles:

  • Casement
  • Awning
  • Specialty

Ultra Series

The Ultra Series exterior is made from extruded aluminum and can mimic the look and style of wood windows with warm wood interior and exterior trim. Kolbe describes the Ultra Series as being designed for versatility, durability and performance and have options for storm-resistance in hurricane-prone coastal areas.  This series compliments both modern and traditional architecture and comes in a variety of options for hardware, divided lite profiles and patterns, and aesthetic and efficient glass.  There are over 50 standard color options for the exterior including custom colors and more than 20 interior prefinished choices and a variety of wood species as well as customized options.  Enhanced energy efficiency and impact resistance standards have been verified by PHIUS (Passive House Institute US). Ultra Series windows are available as new construction and double-hung styles are available as replacement units.

The Ultra Series is available in the following styles:

  • Casement 
  • Awning

All Forgent Series windows have a Glastra exterior with a choice of a Glastra or natural wood for the interior with energy-efficient and impact-resistant options for local climates and weather.
