When design meets performance, great things happen. See how this modern Sydney home achieved a 7-star energy rating with ROPO's thermally broken aluminium windows — built to impress and built to last.
Project Overview
In the heart of Sydney, a local builder sought to create a modern home that would exceed both aesthetic expectations and thermal performance requirements. The goal? To meet a 7-Star Energy Rating, while incorporating unique design elements like arched windows.
To meet this vision, ROPO delivered a full set of thermally broken aluminium windows and doors, engineered to meet Australia's strict AS2047, AS1288, and WERS certification standards.
Project Highlights
ROPO supplied and customized set of double glazed aluminum windows and doors, including:
Aluminium Awning Windows
Aluminium Casement Windows
Aluminium Arch Windows (custom-designed)
Aluminium Sliding Doors
Aluminium Hinge Doors
The Power of Thermal Break Technology
To achieve the desired energy performance, we used:
Thermally Broken Aluminium Frames
Featuring Technoform Bautec™ PA66 thermal break technology
Reduces heat transfer across the frame
Achieves U-values as low as 1.0 Btu/hr·ft²·°F
Ideal for meeting Passive House and high-star energy targets
These frames separate interior and exterior aluminium with a high-performance polyamide bar, minimizing energy loss while maintaining structural strength and design flexibility.
Material & Hardware Details
Powder Coated White Finish using Interpon Powder Coating – 10 Year Warranty
Double Glazing with Low-E Glass + Argon Gas, Toughened Glass, compliant with AS4666
Black Aluminium Spacer inside the IGU
Colonial Bars between the glass units for a refined traditional aesthetic
German ROTO Multipoint Locking System for enhanced security and operation
EPDM Rubber Strips for improved sealing and weather resistance
A Statement in Design: Custom Aluminium Arch Windows
One of the standout features of this project is the inclusion of arched aluminium windows, a bespoke design element tailored to the homeowner's request. These arched profiles demonstrate ROPO's ability to go beyond standard frames and deliver architectural beauty without sacrificing performance.
A Builder's Feedback
