The Evolution of Air Distribution

DUCTUS is redefining air distribution in the Australian HVAC industry through advanced lightweight pre-insulated duct technology (LWDT).

Our systems fundamentally change how ductwork is designed, installed, and performs over its lifecycle—delivering measurable improvements in efficiency, constructability, and long-term reliability.

Working with globally proven technologies including Regal Premium Duct Board, AFLO, and Kingspan systems, DUCTUS delivers solutions that are:

• Significantly lighter
• More energy efficient
• Faster to install
• Easier to coordinate
• Proven across major infrastructure and commercial projects

This is not conventional ductwork—it is a complete re-engineering of airflow delivery systems.

Proven on Major Projects

DUCTUS systems are installed across some of Australia’s most demanding and high-profile projects, including:

• Sydney Opera House
• Sydney Central Tower
• Sydney Airport
• Bendigo Hospital
• Ipswich Hospital
• West Coast Eagles Training Facility
• Her Majesty’s Theatre
• Vaxxes Biomedical Facility

These projects demand:

• Complex services coordination
• High-performance airflow systems
• Architectural integration
• Long-term operational reliability

Lightweight Pre-Insulated Duct Technology (LWDT)

At the core of DUCTUS is pre-insulated duct technology, eliminating the need for traditional sheet metal ducting and secondary lagging.

Key Engineering Advantages

• Faster installation compared to traditional systems
• Dramatically reduced air leakage (as low as ~1.5–5%)
• Integrated insulation—no secondary lagging trades required

All systems are fully compliant with:

• National Construction Code (NCC)
• AS4254.2 ductwork standards

Constructability First — Designed for Real Projects

On-Site Flexibility Where It Matters

DUCTUS systems are engineered for real-world construction environments, particularly:

• Refurbishment projects
• Brownfield upgrades
• Congested ceiling spaces

Installers can:

• Navigate existing structures with ease
• Adapt to undocumented services
• Resolve clashes without costly redesign delays

Seismic Design Efficiency — Practical Benefits under AS 1170

With the latest updates to AS 1170.4:

• Ductwork systems ≤ 10 kg per metre (individually supported) may not require seismic bracing

DUCTUS lightweight systems enable:

• Reduced seismic restraint requirements
• Less structural coordination
• Faster installation and lower costs

Additionally, Ductus has collaborated with specialist engineers and Gripple systems to develop verified seismic-compliant solutions tailored for lightweight duct systems.

Performance in Challenging Environments

Condensation Control — Thermablock Innovation

Thermoblock technology introduces a PVC/aluminium hybrid thermal break system that:

• Prevents surface condensation
• Maintains temperatures above dew point
• Eliminates moisture-related IAQ risks

Ideal for:

• Hot and humid climates
• Aquatic centres
• Food and pharmaceutical facilities

Acoustic Performance — AcoustiPlus

DUCTUS Regal AcoustiPlus delivers:

• High acoustic absorption in minimal thickness
• Noise Reduction Coefficient (NRC) ~0.40 (15mm)

Additional benefits:

• Anti-microbial properties
• Low VOC materials
• No fibre release (unlike traditional fibreglass insulation)

Antimicrobial Air Distribution — AFLO Active

DUCTUS integrates AFLO Active technology, which:

• Utilises Silver Zeolite compounds
• Actively reduces pathogens within the airstream
• Targets bacteria, mould, and viruses

Tested against pathogens including:

• Legionella
• Staphylococcus
• E. coli

Real Design Impact — Why Engineers Specify DUCTUS

Spatial Efficiency & Coordination

• Slim duct profiles (no traditional flanges required)
• Reduced hanger requirements
• Improved ceiling space coordination

On projects such as Sydney Central:

• Exposed ductwork required both performance and aesthetics
• Lightweight systems enabled floating architectural designs
• Reduced structural load and increased usable headroom

Installation & Programme Advantages

• Faster installation
• Reduced labour requirements
• Fewer trades on site
• Lower programme risk

Value Across the Project Lifecycle:

For Mechanical Contractors (D&C)

• Faster installs and reduced labour costs
• Flexibility to adapt on site
• Reduced seismic bracing scope
• Lower coordination risk

For Facility Managers

• Lower energy consumption
• Reduced leakage and maintenance
• Improved indoor air quality
• Long-term durability and corrosion resistance

Applications Across High-Performance Environments

DUCTUS systems are widely used in:

• Healthcare and hospitals
• Commercial offices
• Industrial facilities
• Food and pharmaceutical manufacturing
• Swimming pools and humid environments
• Data centres and IT facilities

Engage Early — Unlock Full Value

The full benefits of DUCTUS systems are realised when engaged early in the design process, including:

• Airflow strategy development
• Duct routing and sizing optimisation
• Prefabrication planning
• Seismic and structural coordination
