Supera vs. Supera Passive: Which High-Performance Window Is Right for Your Project?
In energy-efficient building design, window selection plays a crucial role in overall building performance and long-term value. INTUS Windows offers the Supera polymer window line in two distinct variations: Supera and Supera Passive. While they may look similar on the surface, their construction, thermal performance, and intended use cases reveal clear differences. This article breaks down these key distinctions, based entirely on verified specifications from INTUS.
Supera Series: Strong, Flexible, High-Performance
Supera is INTUS’ high-performance polymer window line designed for both commercial and residential applications. Available in both CW (Commercial Window) and AW (Architectural Window) classifications, it combines structural durability with solid energy and acoustic performance.
Key Features:
Material & Construction: Durable polymer frames reinforced with steel, ensuring long-term strength and structural stability, especially in mid-rise and high-rise applications.
Thermal Efficiency: Dual or triple-pane insulated glazing options, filled with inert gas (argon), provide strong thermal insulation. U-values typically range from 0.15–0.29 BTU/ft²·°F, depending on glass configuration.
Sound Insulation: High STC 31–47 / OITC 20–38 ratings make these windows suitable for urban, noisy environments like near roads or airports.
Compliance: Supera products meet or exceed NFRC, LEED, Net-Zero, and PHIUS guidelines, offering robust sustainability support without compromising on budget or aesthetics.
Applications: Ideal for multi-family housing, schools, hospitals, and commercial renovations — projects where energy efficiency and structural performance must coexist with cost-efficiency.
Supera Passive: Engineered for Passive House Standards
For projects aiming at the highest level of thermal performance, the Supera Passive system is designed to meet and exceed Passive House Institute (PHI) standards. It’s not just an upgrade — it’s a fully optimized window solution for ultra-low-energy buildings.
Key Features:
Certified Passive Component: PHI-certified with a phB performance class, making it suitable for Passive House projects in cool and temperate climates.
Frame Technology: Uses a multi-chambered profile with non-metallic (fiberglass composite) reinforcements, significantly reducing thermal bridging compared to steel-reinforced frames.
Glazing: Equipped with triple-pane IGUs up to 48 mm thick, including warm-edge spacers, argon gas, and low-E coatings for best-in-class thermal performance.
Thermal Performance: Achieves U-values of 0.16–0.19 BTU/ft²·°F, aligning with global Passive House targets.
Best for: Net-zero homes, cold-climate buildings, and Passive House-certified projects where maximizing every BTU matters.
Choosing Between Supera and Supera Passive: What Fits Your Project Best?
Choose Supera if you're looking for:
High energy performance for general-purpose commercial and residential buildings.
A balance between thermal performance and cost.
Flexibility across different project types and code requirements.
Choose Supera Passive if your project requires:
Certified Passive House performance.
Maximized insulation and airtightness for net-zero or cold climate designs.
Meeting strict building energy codes or Passive House certification standards.
Final Thoughts
Both Supera and Supera Passive represent INTUS’ commitment to high-performance window engineering, sustainability, and long-term ROI. The difference lies in how far your project needs to go in terms of energy savings and certification.
If you're building a school, a multi-family development, or a Passive House retreat, there's a Supera solution to meet your goals.
