Kolbe and LuxWall Partnership brings Vacuum Insulating Glass to Designers, Builders and Homeowners

Kolbe and LuxWall partnership offers VIG to residential design

Wausau, Wisconsin (February 13, 2024) – Kolbe Windows & Doors announced their partnership with LuxWall, Inc. to offer vacuum insulating glass (VIG) as a new, high-efficiency glass option for designers, builders and homeowners.

VIG is an innovative technology that features a airless space between two panes of glass called a vacuum. The unique characteristics of the vacuum allow the glass to achieve insulating values similar to that of wall insulation. LuxWall’s VIG design—called Enthermal™—dramatically reduces heat gain from the sun and heat loss from a warmed interior, decreasing energy consumption and costs. An additional benefit of Enthermal is the potential for improved acoustic performance when compared to standard glass products.

LuxWall’s development of Enthermal represents significant progress in glass innovation as it is fully tempered and the first VIG product made in America.

“LuxWall has made tremendous strides in developing effective, reliable and aesthetically pleasing vacuum glass technology,” said Jeff DeLonay, Kolbe’s president. “We are honored to be collaborating with them at this critical point in their growth, and we are enthusiastic about providing this innovative option for our energy-conscious customers in the residential market.”

When compared to similar high-efficiency glass technologies like triple-pane glass, Enthermal is significantly thinner and lighter. These characteristics are inspiring potential applications not only in new construction but also in residential renovation and historical retrofit projects.

“Kolbe is the perfect partner to introduce a whole new level of glass performance to the North American market,” said LuxWall CEO Scott Thomsen. “Kolbe’s customers demand the best in quality and performance, and together we will bring them the best of both. We appreciate the support from the entire Kolbe team and look forward to a great launch.”

LuxWall’s Enthermal will be available as a glass option in select Kolbe products later this spring.
