Located in the prime urban precinct of North Sydney, New South Wales, the residential development at G01, G05, 103/5 Doohat Avenue represents modern high-density apartment living. As an urban Class 2 Multi-Unit residential project, the building required advanced window and door assemblies capable of delivering strict acoustic dampening, optimal energy efficiency, and structural weather resistance under the Australian National Construction Code (NCC).

To meet these high-performance energy mandates and architectural design criteria, Meichen Windows & Doors engineered and supplied a comprehensive, custom-made overseas fenestration package. Featuring a full 100 mm commercial framing envelope, thermally broken aluminum construction, integrated flush drains, and tinted low-E double glazing with grey glass makeup, the project exemplifies Meichen’s capability in delivering certified commercial glazing systems for modern Australian apartments.

System Architecture & Engineering Highlights

DOOHAT AVENUE NORTH SYDNEY — FENESTRATION SYSTEM MATRIX

• Primary System Series: ACG100 & ACG150 Commercial Thermally Broken Series
• Frame Depth & Rigidity: Full 100 mm Heavy-Duty Commercial Envelope
• Threshold Architecture: Flush Drains Sub-Sill Barrier-Free Drainage
• Glazing Configuration: Double Glazed Low-E with Tinted Grey Glass Makeup

1. Advanced Thermally Broken 100 mm Commercial Framing

Modern North Sydney residential developments require low U-values to comply with strict energy standards (such as NCC Section J and BASIX targets) while maintaining structural resistance against high urban wind pressures.

• Structural Polyamide Thermal Barriers: High-density polyamide (PA66) thermal break strips physically separate the interior and exterior aluminum profiles, drastically reducing thermal bridging, condensation risks, and energy loss.

• Full 100 mm Profile Depth: The ACG100 system features a 100 mm profile depth engineered for high structural inertia, ensuring that window mullions and door frames satisfy the deflection limits set out in AS 2047.

2. ACG100 & ACG150 Operable System Integration

The apartment units at Doohat Avenue incorporated a coordinated suite of operable windows and doors designed for urban living convenience and safety.

• ACG100 Awning Windows: Provide controlled, rain-safe natural ventilation with continuous multi-layer EPDM rubber perimeter gaskets that lock out street traffic noise and wind-driven rain.

• ACG100/150 Sliding Doors: Heavy-duty sliding assemblies engineered with precision tandem rollers, allowing large glass panels to slide effortlessly while offering high weather tightness.

• ACG100 Commercial Hinged Doors: Heavy-duty entry and balcony access doors equipped with multi-point locking hardware for elevated security and perimeter sealing.

3. Flush Drains Threshold Design & Grey Low-E Double Glazing

Urban multi-residential balconies demand a clean visual transition from indoor living areas to exterior outdoor decks without compromising water penetration resistance.

• Barrier-Free Flush Drainage: The custom sub-sill includes concealed flush drainage slots that channel driving rain rapidly away from internal tracks, preventing water ingress even during intense coastal storms.

• Double Glazed Low-E with Grey Glass Makeup: Combining spectrally selective Low-E coatings with a stylish grey tinted glass makeup mitigates solar glare, enhances occupant privacy, and lowers the Solar Heat Gain Coefficient (SHGC) to maintain comfortable indoor ambient temperatures year-round.
