At Kolbe, 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 most climate zones. For even better energy performance, several products include triple pane glass as standard, and as an option on even more products.
Several of Kolbe's products have met the most rigorous standards set by ENERGY STAR. For this reason, they have been designated as among ENERGY STAR's Most Efficient for 2015. Learn more about this designation and the products that meet it on our What's New page.
Due to high quality standards, many Kolbe products also meet performance levels required for green building, sustainable design, and passive house design protocols.
For example, PHIUS (Passive House Institute US) reviews manufacturer-supplied specifications for window products and recommends products that are suitable for passive house projects by climate zone. VistaLuxe® Collection and Ultra Series casement, awnings, and other products with specific options have been PHIUS verified. Learn more about the PHIUS Certified Data for Windows program, as well a Kolbe's PHIUS-verified products on our What's New page.
Finally, 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 design project provides all the benefits of a healthy and comfortable living or working environment.
