Rehau Window Solutions has introduced a major industry milestone with the ARTEVO entrance door, the first PVC entrance door system worldwide to achieve Passive House certification from the Passive House Institute (PHI) in Darmstadt. The certification was formally presented at Fensterbau Frontale 2026 in Nuremberg, confirming compliance with one of the most demanding global standards for energy-efficient building components.

The certified ARTEVO max entrance door achieves outstanding thermal performance with U-values as low as 0.8 W/(m²K), meeting PHI requirements for the “cool temperate” climate zone. This performance is enabled by the combination of RAU-FIPRO X, a high-performance fiber-reinforced PVC material, and integrated LowE (low-emissivity) technology, which significantly reduces heat loss while maintaining structural stability and design flexibility.

Beyond its thermal performance, the system is designed as a modular platform. The ARTEVO portfolio is set to expand in December 2026 with a sash solution for overlay panels, enabling broader architectural applications. A lift-and-slide door variant is also planned, extending the system into large-format openings. In parallel, Rehau is developing a smart access solution in cooperation with Nuki, integrating digital entry systems into the platform for enhanced security and convenience.

According to Rehau CTO Frank Zimmermann, the certification reflects continuous system-level development that merges energy efficiency with modern design requirements. The Passive House approval also provides independent validation, strengthening its role in technical specification and project planning.

For architects, fabricators, and developers, PHI certification serves as a verified benchmark for ultra-low-energy building envelopes. It supports compliance with tightening European energy regulations and helps reduce heating demand in residential and commercial buildings.
