Kolbe products are continually designed to meet or exceed today's stricter building codes and standards for energy efficiency. Now, Kolbe is proud to offer a wide range of VistaLuxe® Collection and Ultra Series windows and doors that have been verified by the Passive House Institute US (PHIUS). Our range of certified products means that American-made windows and doors for an entire passive house project are available from one manufacturer.

Our PHIUS-verified products have the same attention-to-detail and superior quality for which Kolbe is known. Plus, these products are available with the multitude of options you've come to expect from Kolbe. We are pleased to offer windows and doors that meet the strict PHIUS guidelines, so that we can help in the commitment to meeting high performance building principles.

NOTE: Passive House performance criteria are dependent upon a number of factors, including LoE coatings, lite divisions, and elevation placement.

The PHIUS Certified Data for Windows program reviews manufacturer-supplied specifications for window products and recommends products that are suitable for passive house by climate zone. Download a list of Kolbe products that have been PHIUS verified.
