A Passive House is the gold standard of energy-efficient construction, consuming up to 90% less heating energy than existing conventional buildings and 75% less than typical new builds. At H.O. Schlüter, our passive house window systems are engineered to make this possible, meeting the strict requirements of both PHIUS and PHI certification. With U-values as low as 0.12 Btu/hr·sq ft·°F, we provide some of the most efficient windows available on the market today. The system’s exceptional performance is achieved through reinforcement chambers in the sash and frame, filled with ProEnergyTec® foam — a recyclable material that delivers outstanding thermal insulation while supporting sustainable building practices. These windows easily meet Passive House standards, ensuring annual heating requirements of just 4,755 Btu/sq ft of living space. Compatible with both the H.O. Schlüter Classic and AluClip Systems, this solution combines modern design with large glass surfaces that not only maximize natural light but also increase solar heat gains for improved efficiency.
