Passive House Windows

Beyond standards. Built to last.

What is Passive House?

Passive House (Passivhaus) and PHIUS are among the most demanding benchmarks for energy efficiency in the world. For a client, this essentially means one simple thing: products designed to go further in insulation, airtightness, and comfort. The result: less energy loss, a more stable indoor temperature, reduced discomfort near windows, and stronger long-term savings potential.

While building codes set the minimum and ENERGY STAR is often a good starting point, PHI and PHIUS approaches push the requirements much further. They open the door to a new generation of projects—whether new builds or renovations—aiming for performance levels compatible with ambitions such as LEED Platinum, BREEAM Outstanding, or carbon neutrality. The result: less energy loss, greater comfort, and a building envelope designed to last.

That’s why we work with recognized partners such as Reynaers, while also developing our own solutions. If we hold some of the most demanding certifications in the industry, it’s because they provide tangible proof of our commitment to go further.

Benefits of Passive House windows

01

Superior insulation

Passive House frames and glazing significantly reduce heat loss, helping lower heating and cooling demands well beyond common standards such as ENERGY STAR.
02

Enhanced everyday comfort

By keeping the interior surface of the glass more temperate, Passive House products improve comfort near openings, reduce the cold-wall effect, and contribute to a more stable indoor temperature.
03

Long-term impact / environment

Beyond immediate performance, these products are designed to deliver lasting value. By reducing energy needs and emphasizing durability, they support a more responsible approach to building—one that looks toward the future.
