Improve air quality in your home with passive ventilation
Passive ventilation uses doors, windows, vents, louvres and other openings to bring fresh air into your home and let stale air out. This will make your home healthier by improving air quality and reducing mould, mildew and condensation. During the cooler months, it will make your home easier and more efficient to heat.
Ventilation is important for providing a healthy indoor environment and works best if air has clear, uninterrupted pathways through your home. You can maximise air flow by designing open plan areas or having high vents or other openings between rooms. Where cooling is required, windows or other openings up high or on upper levels can be opened to let warm air escape. In winter, well-designed passive ventilation refreshes the air in your home without creating draughts or letting out too much heat.
If your home is designed for passive ventilation, all you’ll need to do is open and close windows, doors or other vents as needed to reduce the temperature and improve the quality of the air you’re breathing. Effective ventilation is necessary for temperature control and air quality.
NZWindows have a range of passive ventilation options available – to the straightforward Sashvent and Aerovent system, to the sophisticated Ventient system.
Sashvent System
An effective ventilation system which delivers background ventilation through the bottom of an opening window.
- Installed into bottom-opening windows (awning), meaning it is hidden away.
- A manual slide allows the vent to be opened and closed.
- Insect mesh barrier ensures only fresh air is allowed in.
Aerovent system
Designed primarily for use at the top of windows or in transoms, the ‘Aerovent’ has a generous weather hood on the outside and is opened or closed on the inside by a slide. The airflow is through a series of vertical slots that are hidden from view, and the slide is a U-channel that also deflects air movement to prevent draughts.
- Improves airflow with less visual intrusion.
- A cover on the inside also acts as a manual slide for opening and closing.
- Air movement is directed upwards to prevent draughts.
- Internal insect mesh barrier ensures only fresh air is allowed in.
- Ideal for cross-ventilation and air flow.
Ventient System
Naturally automated trickle ventilator suitable for high-end residential and commercial projects
- Has an internal device, which automatically opens and closes in response to outside air temperatures.
- Installed in Metro or APL Architectural Series windows or doors.
- Mesh prevents insect entry to the aluminium Ventient box and dust and pollen filters are also incorporated.
