Materials & Technical Features
ROPO supplied thermally broken aluminum windows that combine cutting-edge insulation technology with sleek aluminum design. These units incorporate:
✅ Technoform Bautec™ thermal break (PA66) – Separates the interior and exterior aluminum profiles using a high-performance polyamide bar, dramatically reducing the frame's U-factor from around 2.0 to approximately 1.0 Btu/hr·ft²·°F. This performance is critical for Passive House targets.
✅ Triple glazing with Low E glass & warm-edge spacer – Enhances insulation and eliminates cold bridging around the window perimeter.
✅ German ROTO multi-point locking hardware – Guarantees long-term security, stability, and smooth operation.
✅ EPDM rubber seals – Offers air-tightness, noise reduction, and moisture protection even in extreme weather.
✅ Powder coating by Interpon (10-year warranty) – Ensures the frames are UV-resistant and corrosion-proof, even in coastal or alpine environments.
Client Testimonial – Steve & Kathy's Feedback
"We are extremely satisfied with the triple glazed windows provided by ROPO. Living in the cold climate of the South Island, thermal insulation and energy efficiency were top priorities when building our home. Since installing ROPO's triple glazed windows, our house stays warm in winter and cool in summer, with minimal need for additional heating or cooling. It has significantly reduced our energy costs.
The sound insulation is also excellent — we can enjoy a peaceful indoor environment even during storms or traffic outside. Just as importantly, the windows not only perform exceptionally well, but their sleek design also complements the modern style of our home perfectly.
ROPO's professional team provided great support throughout the design and delivery process. Everything went smoothly. If you're looking for high-performance, energy-efficient, and reliable windows and doors, we highly recommend ROPO's triple glazed windows."
