  • This lake home project on Pearl Lake near Traverse City, Michigan showcases 82 Kolbe-crafted windows & doors. Our Ultra Series products helped this project earn a Michigan ENERGY STAR grant. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&projectCategoryID=10&pI=34">Learn more</a> about this project.
  • The builder specified Kolbe products both for their aesthetic match and their energy efficiency track record. The builder noted, "...the superior ratings of Kolbe\'s products means homeowners can enjoy the views without thinking that their dollars are flying out the windows – or the doors." <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&pI=34&ppID=51&projectCategoryID=10">Learn more</a> about this project.
  • Ultra Series windows and doors were chosen for this Rainbow Adobe home. Each was glazed with LoE²-240 solar control glass. The glass\' reflective solar properties help manage unwanted heat gain, tones down the glare and preserves the clarity of view. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&pI=37&ppID=46&projectCategoryID=3">Learn more</a> about this project.
  • Ultra Series casements, patio doors and a garden window were chosen for this Texas home. Each unit was glazed with LoE²-240 solar control glass, which helps manage unwanted heat gain and tones down the sun\'s glare. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&pI=37&ppID=47&projectCategoryID=3">Learn more</a> about this project.
  • AIA Architect Peter Pfeiffer\'s Austin home features over 50 Heritage Series wood windows - including double hungs, single hungs, awnings, transoms, and casements. Properly installed, quality windows are a big factor in minimizing energy loss from unwanted warm air infiltration. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=12&pc=12&locationID=109&keyword=&pl=331">More photos</a>
  • This home\'s design included venting windows that help further reduce the energy required to cool this home, while also providing the benefits of ample daylight and good air circulation. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=12&pc=12&keyword=%20&locationID=109&pl=332&start=2">More photos</a>
  • The Green Builder® VISION House was constructed using Ultra Series windows and doors. Helping lower energy consumption and costs, the windows reflect unwanted solar heat in the summer and retain desired heat during cooler months. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&projectCategoryID=14&pI=44">Learn more</a> about this project.
  • This Denver home features energy-efficient Ultra Series windows & doors. The LoE²-270 glass enables the windows to meet or exceed ENERGY STAR guidelines in most U.S. climate zones. <a href="http://www.kolbe-kolbe.com/gallery/index.cfm?pcID=5&pID=31&projectCategoryID=14&pI=31">Learn more</a> about this project.

Kolbe Offers Energy Efficient Window & Door Glass Options:

  • Double pane insulating glass units with LoE² coating and argon gas are standard on most of our products, helping them to meet or exceed ENERGY STAR® guidelines in most U.S. climate zones
  • ThermaPlus LoE glass option enhances the thermal performance of our windows, reducing energy costs
  • Even higher performing units with  triple pane glass  can help meet or exceed the insulating values required by ENERGY STAR's climate zones in the USA and Canada

energy starKolbe products are designed to meet or exceed today's stricter building codes and standards for energy efficiency, as well as the energy requirements for green building rating systems.

We use the latest innovations in LoE technologies in various combinations, so we are able to offer glass that is best suited to any climate. Most of our products are glazed as standard with double pane, insulating glass units with LoE coating(s), argon gas, and a Thermo-Edge stainless steel spacer bar system. These elements provide great thermal performance as well as excellent UV protection.  We also offer LoE glass coatings that help minimize solar heat gain in very warm climates. Many Kolbe products meet or exceed ENERGY STAR guidelines in the USA and Canada.

For even better energy performance, Kolbe now offers triple pane glass on several of its products. Take a close look at Heritage & Ultra Series Majesta Double Hungs, as well as Ultra Series Crank-Out Casements and Sterling Double Hungs. Windquest® Series Crank-Out Casement, and Radius & Geometric Windows are available with triple pane glass that achieves values of R-5. Look for more of our products to add this triple pane glass option in the near future.

Remember, for windows and doors to provide optimal energy efficiency, they must be flashed, caulked and sealed properly at the time of installation. All of our products are shipped with detailed installation instructions, which emphasize the importance of these final steps to the builder. Once properly installed, the energy efficient technology built into Kolbe products will further ensure your green design project provides all the benefits of a healthy and comfortable living or working environment.
