Located on Kaluna Street, this contemporary multi-dwelling Duplex Building project showcases modern residential architecture characterized by expansive facade openings, curved glass elements, and seamless indoor-outdoor living transitions.

To address varying energy efficiency benchmarks, project budgets, and orientation requirements across the development, Meichen Windows & Doors engineered two tailored commercial glazing configurations:

1. Option A (High-Performance Thermal Envelope): Featuring the ACG100 Thermally Broken System for maximum thermal insulation and energy efficiency.

1. Option B (Cost-Optimized Commercial Envelope): Utilizing the MA100 Non-Thermally Broken System for robust commercial strength with high-efficiency double glazing.

Both Duplex Buildings utilize a full 100 mm commercial framing depth, customized overseas profile extrusions, and integrated flush drains sub-sill technology, delivering versatile fenestration options for modern duplex developments.

Deep Dive: Glazing Configurations & Engineering Analysis

KALUNA STREET DUPLEX — SYSTEM ARCHITECTURE MATRIX

[ OPTION A: ACG100 SERIES ]
├── Structural Depth : 100 mm Heavy Commercial Profile
├── Thermal Barrier  : Polyamide (PA66) Insulation Strip
└── Glazing Tech     : Double Glazed Insulated Units (IGU)

[ OPTION B: MA100 SERIES ]
├── Structural Depth : 100 mm Heavy Commercial Profile
├── Thermal Barrier  : Solid High-Inertia Aluminium Extrusion
└── Glazing Tech     : Double Glazed Insulated Units (IGU)

1. System Engineering & Thermal Performance

Both systems are built around a full 100 mm commercial sub-frame, providing high visual consistency across the entire facade while offering distinct thermal properties:

• ACG100 Thermally Broken System: Isolates indoor and outdoor aluminum extrusions using structural polyamide (PA66) thermal breaks. This prevents thermal conduction, drastically reduces ambient air-conditioning loads, and satisfies strict NCC Section J and BASIX energy efficiency standards.

• MA100 Commercial System: Utilizes solid, heavy-gauge commercial extrusions paired with high-performance double glazing. It offers high structural resistance and cost efficiency, making it an ideal choice for mild orientation zones or value-engineered duplex builds.

2. Operable Systems & Functional Design

Both ACG100 and MA100 product lines feature a complete range of matching operable door and window configurations tailored for modern residential living:

• Awning Windows (ACG100 & MA100): Engineered with top-hung sashes and multi-point perimeter locks. High-grade EPDM rubber gaskets maintain air-tight seals, preventing water penetration during extreme storm events.

• Sliding & Stacker Door Systems (ACG100/150 & MA100/150): Deep 100 mm to 150 mm track options accommodate heavy double-glazed panels, allowing effortless sliding operation for wide balcony and courtyard openings.

• Hinged Doors (ACG100 Series): Heavy-duty commercial entry and terrace doors designed for high-frequency use, offering robust multi-point security.

3. Integrated Flush Drains Barrier-Free Drainage

Both configurations incorporate Meichen’s specialized flush drains threshold technology:

• Zero-Step Indoor-Outdoor Flow: Concealed sub-sill drainage allows external balcony tracks to sit flush with internal floor finishes, creating a barrier-free transition.

• Rapid Stormwater Evacuation: Integrated internal drainage channels direct rainwater away from door tracks, preventing water ingress even under intense wind-driven rain conditions.

Compliance and Engineering Accreditation

To support seamless building consent sign-offs for Australian multi-residential developments, both options are backed by comprehensive certification:

AGWA Corporate Membership: Meichen is an active corporate member of the Australian Glass and Window Association (AGWA).

In-House AGWA/AFTI Certified Engineers: Designed and verified by qualified engineers fluent in AS 2047 (Windows & External Glazed Doors), AS 1288 (Glass in Buildings Selection & Installation), and NCC mandates.

Verified Quality Assurance: Backed by independent testing and auditing schedules under the CSi PAS-Mark and JAS-ANZ frameworks.
