Introducing the qVENT Type 3 the latest Australian innovative design and made in Australia to support ventilation systems. It is specifically designed to enhance air circulation, energy efficiency, and sound attenuation in modern spaces. Our product stands out due to it louvre-less design made from durable plastic and fully patented to ensure exclusivity and superiority in the market.
Key Benefits of qVENT Type 3
- Acoustic Sound Attenuation: Our mirrored design incorporates sound-absorbing foam, offering noise transmission reduction compared to conventional louvered vents or just a simple gap at the bottom of a door.
- Enhanced Airflow: qVENT Type 3's design ensures excellent airflow, promoting better ventilation, reducing condensation, and improving overall air quality.
- Security and Privacy: Our design restricts inspection cameras more effectively, providing better privacy.
- Extremely effective for switch and computer room equipment.
- Modern Aesthetic: qVENT Type 3 features a sleek, contemporary design with recessed screw fixings, blending seamlessly with modern interiors.
- Energy Efficiency: By facilitating better air movement even when doors are closed, Qvent Type 3 contributes to a more energy-efficient heating system, reducing energy usage and costs.
- No Undercut Needed: Eliminates the need for door undercuts, enhancing acoustic performance and preventing pests like mice and insects from infiltrating through closed doors.
- For use on solid core or hollow core doors.
- 14200mm² of opening which satisfies ABCB Housing Provisions Standard 2022 (NCC) Section 10.8.2
Instead of removing a door to undercut it, achieve 14000mm2 for building code with an acoustic performing door vent that has a modern looking design, getting away from traditional louvred commercial looking door vents.
Acoustic Attenuation Performance
Bathrooms typically have elevated mid to high frequency noise levels compared to other rooms within a dwelling. This can lead to extra annoyance for those outside the bathroom and a lack of privacy for those within. The amplification of high frequency noise in a typical bathroom may be attributed to the following factors:
The presence of hard, reflective surfaces such as mirrors, glass, tiles and porcelain coupled with minimal soft furnishings contribute to an increase in the level of the reverberant field, amplifying mid-high frequency noise produced by plumbing fixtures and bathroom activities such as running water, showering and toilet flushing.
qVENT vs 25mm Gap (Larger is better)
Specimen R Value (dB) 1/3 Octave data from CSIRO Measurement Report – Report no: TL811-08-1, TL811-01-1 & TL812-01-1
qVENT (Type 3) focuses on attenuation in the mid-high ranges, with a 2-3 dB improvement from 800Hz to 1600Hz and a 2-4dB improvement from 2000Hz to 5000Hz when compared to a 25mm gap.
Data collected on noise levels in bathrooms reinforces the expected amplification of mid-high frequency noise seen in a typical bathroom with a high proportion of reflective surfaces with an absence of absorptive surfaces (see absorption coefficients table in Engineering Noise Control sixth edition pages 373-375).
Why Choose qVENT Type 3 Over Competitors?
Outdated Designs: Competing louvered vent designs are aesthetically dated and visibly marred by exposed screw fixings.
Ineffective Sound Attenuation: Most existing systems do not offer effective sound mitigation and cannot be retrofitted with sound absorption materials.
Security Flaw: Conventional louvered vents and gaps under doors are susceptible to privacy breaches via inspection cameras.
Design Shortcomings: Many rival products feature components that fit inside each other, causing sound vibrations to travel through the materials.
qVENT Type 3 transcends current door vent systems with its innovative, patented upside-down mirrored design. It is not merely a vent but a comprehensive solution to enhance energy efficiency, sound attenuation, security and overall air quality within any building. Choose qVENT Type 3 for a modern, efficient and more secure approach to door ventilation and improving the indoor air quality in your building.
For more information as to why you might want to provide air for ceiling fans, click here or understand ducted heating energy efficiency
In many cases Bathroom and Toilet fans cannot get of enough air to move through the fan. With air coming from down low in a door, humidity and smells move quickly and efficiently outside via your ceiling fan.
At Efficiency Matrix we take air flow quite seriously, so we measured the actual flow rates within an average bathroom with a single ceiling fan. With a door vent fitted, the flow of air up and out of the ceiling fan is increased by 33%. The substantial increase in air flow as a result of a door vent can improve air quality and thus lessen the incidence of mould.

Ducted heating systems can become unbalanced when the supply vent in a home is not able to get back to the return vent. This happens when doors in the home are kept closed. The best way to solve this problem, is to let the air get back via a door grill.
