Thermally broken aluminium windows feature an insulating polyamide barrier engineered into the frame, separating the interior and exterior aluminium sections to prevent heat transfer — delivering superior energy performance without compromising the strength and sleek aesthetics of aluminium.
This technology is essential for meeting Australia’s increasingly stringent energy efficiency standards. The polyamide thermal break creates a physical separation between the inner and outer aluminium profiles, dramatically reducing thermal conductivity through the frame and minimising condensation on interior surfaces.
At Smart Doors & Windows, we supply and install thermally broken aluminium window systems across Melbourne for commercial, multi-residential, and high-performance residential projects — from NCC-compliant office buildings to passive house designs.
Technical Specifications
Our thermally broken aluminium window systems are precision-engineered to deliver outstanding thermal and acoustic performance while meeting the demanding requirements of commercial construction.
- Frame Construction: Aluminium profiles with polyamide (PA6.6) thermal break barrier separating interior and exterior sections
- Thermal Performance: Dramatically reduces heat gain in summer and heat loss in winter — Uw range from 1.8 to 3.2 W/m²K depending on glazing configuration
- Condensation Control: Thermal break minimises condensation on interior frame surfaces, protecting finishes and improving indoor comfort
- Configurations: Available in casement, awning, sliding, fixed, and hinged door configurations
- Finishes: Extensive powder-coat colour range including Dulux and Interpon options, plus anodized finishes in satin, bronze, and black
- Energy Compliance: Meets NCC Section J commercial energy requirements and residential 6-star and above energy ratings
- Standards Compliance: Certified to AS 2047 (windows and external glazed doors) and AS 1288 (glass in buildings)
Key Features & Benefits
Thermally broken aluminium windows offer a range of performance advantages that make them the preferred choice for energy-conscious architects, builders, and developers:
- Thermal Break Technology: The polyamide barrier creates a physical separation between inner and outer aluminium profiles, reducing thermal conductivity by up to 60% compared to standard aluminium frames
- Enhanced Acoustic Performance: When paired with acoustic glazing, thermally broken systems deliver superior sound insulation — critical for buildings in high-traffic urban areas and flight paths
- Condensation Minimisation: The insulated frame design keeps interior surfaces warmer, significantly reducing the risk of condensation and associated mould growth
- Multiple Configuration Options: Available in casement, awning, sliding, fixed-lite, and hinged configurations to suit any architectural vision and ventilation requirement
- Residential & Commercial Compatibility: Systems are compatible with both residential and commercial framing systems, making them versatile enough for mixed-use developments
- Long-Term Durability: Aluminium frames with thermal breaks maintain structural integrity and finish quality for decades with minimal maintenance
Ideal Applications
Thermally broken aluminium windows are suited to a wide range of projects where energy efficiency and occupant comfort are priorities:
- Commercial Offices: Meet NCC Section J energy requirements while delivering floor-to-ceiling natural light and a modern facade
- Multi-Storey Residential: Essential for apartment buildings and high-rises where energy ratings and acoustic control directly impact occupant satisfaction
- Healthcare & Aged Care: Superior thermal and acoustic performance for patient comfort and wellbeing in hospitals, clinics, and aged care facilities
- Schools & Universities: Energy-efficient glazing that reduces HVAC costs while creating comfortable, quiet learning environments
- Hotels & Hospitality: Premium finish and performance for guest rooms, lobbies, and conference areas where comfort and aesthetics are paramount
- Passive House Projects: High-performance thermal break systems that contribute to the stringent U-value requirements of passive house certification
All our thermally broken systems comply with AS 2047, AS 1288, and NCC requirements for commercial and residential construction. Available powder-coated in any RAL colour or anodized to match your building’s design.
