How to Make the Most of Passive Ventilation Using Windows

Proper ventilation is crucial to keeping a clean, comfortable and safe home. With proper airflow, you can have peace of mind that fresh air is entering your home and you can avoid breathing in stale, polluted indoor air.

Passive Ventilation Using Windows

Heating and cooling systems usually play a significant role in ensuring a well-ventilated home. Nevertheless, your custom windows can also contribute to this goal. In fact, they can be a great source of passive ventilation. Read on to learn more about how you can make the most of your home’s passive ventilation using windows.

How Does Passive Ventilation Work?

Passive ventilation is the use of openings such as windows, doors and vents to bring fresh air into your indoor space. But in order for it to work, the size and placement of these openings should be carefully considered. Furthermore, there should be clear, unobstructed pathways through which air can flow. It would also be good to have open plan spaces or high vents between rooms.

What Can Be Done to Maximize the Use of Windows for Passive Ventilation?

To maximize the passive ventilation that you can get from your replacement window, below are some simple things that you should do regularly:

  • Open your windows for at least 15 minutes, at least five times a week.

  • If you have windows on the south and east sides of your home, you should open them to catch the cool breeze early in the morning.

  • Open your windows on the north and west sides of your home so that air can keep circulating.

  • There should be enough openable windows on each side of your to get the most out of the microclimate breezes.

  • Choose your windows carefully. Certain window styles are better used for passive ventilation than others. For instance, windows that can be opened sideways are more ideal for catching breezes and letting them into your home than, say, awnings.
