Ventilation Solutions for Healthier Homes

The performance of a home - how it breathes, sounds, and conserves energy - is central to specification. Indoor air quality, acoustic comfort, and energy efficiency now drive decision-making - especially in homes that are becoming increasingly insulated and airtight.

Founded in 2007, Schweigen began by addressing one of the most overlooked issues in residential design: the noise and inefficiency of conventional rangehoods. Its solution - relocating the motor from earshot - redefined kitchen extraction.

The powerful yet silent Isodrive® Motor System remains Schweigen’s flagship technology.

The Isodrive® Advantage

The German-engineered Isodrive® motor is mounted away from the cooktop - either externally of the home, or along ductwork in the bulkhead, attic or ceiling space. This provides measurable advantages:

• Silent Operation: Relocating the motor removes the dominant source of kitchen noise, supporting open-plan layouts and acoustic comfort.
• Improved Extraction: Powerful motors pull cooking exhaust out in one seamless action to the outdoors - capturing and expelling smoke, steam, odours and airborne grease before they spread through the home.
• Energy Efficiency: The Isodrive® motor system uses up to 50% less energy than comparable in-hood systems.
• Design Flexibility: Quiet operation allows specifiers to prioritise aesthetics, with inline motor options and product configurations that include undermounts to ceiling cassettes that disappear into cabinetry, bulkheads and the ceiling.
• Performance Ducting: Come bundled with Schweigen SteelFlex™ safety ducting - fire, pest, crush-proof, and guaranteed for life.
• BAL-40 Certified: Engineered for endurance and certified by the CSIRO (Australia’s national science agency) for resistance against up to 40 kW per square metre of radiant heat flux exposure and the very high risk of ember attack. It complies with the Australian Standard AS 39859:2018 for construction materials in bushfire zones.

This innovation has become a benchmark in domestic kitchen ventilation, and provides a foundation for Schweigen’s wider offerings.

From Kitchen Rangehoods to Whole-of-Home Ventilation

Today, Schweigen’s portfolio extends beyond kitchens into bathrooms and whole-of-home systems, reflecting the growing emphasis on Indoor Air Quality (IAQ) in modern housing. For specifiers, this positions Schweigen as a partner in designing homes that meet modern performance and sustainability standards.

Why It Matters

For architects, builders, and designers, Schweigen addresses several specification priorities:

• Indoor Air Quality: Products mitigate cooking by-products, VOCs, and airborne moisture, improving occupant health and reducing maintenance issues.
• Acoustic Comfort: Silent extraction supports the National Construction Code’s provisions for airflow and acoustic comfort, enhancing the quality of open-plan, multi-use living environments.
• Energy & Sustainability: Low-energy external motors reduce operational consumption and support compliance with energy frameworks.
• Design Integration: Slimline and concealed options enable ventilation solutions that complement, rather than compromise, interior design intent.

Beyond the Kitchen

Moisture and odours present ongoing challenges in wet areas, with implications for occupant health and building durability. Schweigen Silent Exhaust Fans use the same external-motor approach to remove humidity efficiently without acoustic disruption - a significant advantage for multi-residential and strata projects where noise transfer is an issue. Best of all, a single motor can vent multiple adjacent rooms.

Tools & Support for Specifiers

Recognising the demands of the built environment sector, Schweigen provides:

• CAD or BIM assets for reference and seamless integration into design workflows.
• Technical documentation aligned with NCC requirements and AS 3959 (bushfire compliance).
• Project advisory in Australia and New Zealand through a dedicated specifier support team, ensuring context-appropriate solutions.

Looking Ahead

As Australia and New Zealand moves toward higher-performing homes and tighter energy standards, ventilation will continue to be a priority. Schweigen’s commitment lies in ensuring that air quality and acoustic comfort become fundamental to design intent.

By combining quiet performance, energy efficiency, and aesthetic flexibility, Schweigen enables specifiers to deliver the next generation of housing with whole-of-home ventilation solutions that are smarter, quieter, and healthier by design.
