The award-winning ventilation for designer abodes you need to know about

For decades, ducting has been hidden above ceilings and behind walls, rarely questioned or improved upon, until the innovative Expella team challenged this convention by developing Coreduct (Trademarked).

Recipient of two Gold 2025 Australian Good Design Awards for the Product Hardware and Building and Engineering categories, Coreduct is a low-profile, flat-pack rigid duct system designed for domestic and commercial ventilation. The product is addressing the inefficiencies of traditional HVAC installations and showing how thoughtful materials and logistics can support sustainability.

For example, Coreduct’s clever flat-pack design reduces transport and storage bulk, while local manufacturing, and using recyclable polypropylene instead of PVC, minimises the environmental impact. The result is a lighter, cleaner, and more sustainable solution addressing common environmental and logistical inefficiencies in the building industry.

The Good Design Awards Jury described the Coreduct system as a “simple but elegant solution addressing a genuine need with demonstrated positive impact,” adding, “the size reduction and efficiency gains in this product are remarkable. If it can scale as a mainstream solution, it has strong potential to shift the industry.”

Sometimes great design comes in the smallest packages, such as Expella’s Ceiling Mounted Humidity Sensor Switch, winning a 2020 Good Design Award Gold Accolade in the Product Design Hardware and Building category (from a record 835 entries).

Developed to detect high humidity within confined spaces (like bathrooms or laundries), the sensor automatically activates the exhaust fan when needed, and switches it off, when the air clears. Why? Think reduced energy use, lower running costs, and improved indoor air quality without any user intervention – now that’s impressive design.

Clearly, the Good Design Award’s judges agreed, who praised the Humidity Sensor, “Clean looking and nicely detailed - an elegant balance of form and function. Smart application of automation with a simple yet fit-for-purpose design that eliminates unnecessary exhaust fan running costs. All homes should have these installed in wet areas.”

The Humidity Sensor Switch is coming soon to the Expella website.

Expella’s commitment to local manufacturing, recyclable materials and energy efficiency reflects the brand’s responsible design philosophy. From smart automation to designer airflow, Expella’s award-winning innovations help create healthier, more sustainable living spaces while working with, rather than against, the interior design.
