Project Overview
This project involves a high-rise residential apartment development in Melbourne, Australia, where strict regulatory compliance and high wind-load resistance were critical requirements.
Located in a metropolitan coastal-influenced zone, the project needed window systems that not only met AS 2047 performance standards, but also aligned with the National Construction Code (NCC) and local building approval processes governed under the Building Code of Australia (BCA).
The developer prioritized certified compliance, long-term durability, and energy performance suitable for multi-storey residential apartments.

Key Project Challenges
1. High Wind Pressure in Upper Floors
Due to the building height, the window systems were required to withstand a design wind pressure of up to 3000 Pa, corresponding to N5–N6 ratings under Australian standards—without long-term deformation or air leakage.
2. Compliance & Certification Approval
The project demanded strict compliance with:
AS 2047 (air infiltration, water penetration, wind resistance)
AS 1288 for glazing safety
NCC / BCA requirements for residential buildings
Melbourne building surveyors required independent test reports from NATA-accredited laboratories, not manufacturer self-certification.
3. Energy Performance Expectations
To align with local energy efficiency assessments, the window solution needed thermal performance consistent with WERS (Window Energy Rating Scheme) evaluation logic.
Our Window & Door Solution
System Selection
A 120 Series thermally broken aluminum window system was selected to balance structural strength and thermal efficiency—well-suited for high-rise apartment applications.

Engineering Design – Cross-Section Details
To ensure resistance against high wind loads, reinforced aluminum profiles with internal ribs were applied.
Key engineering highlights include:
Increased profile wall thickness for structural rigidity
Reinforced internal chambers to resist deformation under pressure
Integrated thermal break structure to improve insulation performance
This cross-section design directly supports AS2047 wind and water performance while enhancing long-term durability.
Implementation Highlights
Project-based customization according to architectural drawings
Strict pre-shipment quality inspections
Specialized steel-frame packaging to prevent glass breakage and profile scratches during sea freight
Complete technical documentation provided to support on-site installation and compliance inspections
All test reports and documentation were prepared to ensure seamless approval by Melbourne building surveyors.
Project Results
Following installation, the window systems successfully passed all required inspections under AS2047 and NCC guidelines.
The developer confirmed stable performance under strong wind conditions, smooth approval processes, and overall satisfaction with product quality and compliance support.
