How to Select a Window Fan for a New Window?

If you want to install a window fan into a brand new pane of glass what sort of things do you need to consider? Continue reading the below article for some of our useful hints and tips for installing and picking the best window fan for your requirements!

Before you install an exhaust fan in a window, you will first need to ensure that the window is suitable for an exhaust fan installation. For instance, many window fans have a large protrusion into the room which will mean the fan cannot be installed on a sliding window or one with solid blinds (ie Venetian blinds).

If you decide that you want the ability to uninstall the fan in the future without an electrician, then selecting a fan with a lead and plug installed would be the most convenient option for you. This is especially true if you have a power point located near the window.

Be mindful that unlike wall or ceiling applications where the plaster or brick can be altered to suit the fan, glass once cut cannot be adjusted so you will need to be sure of the fans’ cut out size before contacting a glazier to professionally cut your hole. Most fans come with a cut out template that the glazier can use as a guide when cutting the hole.

Installing a window fan in a plane of glass that has not had a fan in it previously means you have a much wider range of fans to choose from, and that you can select a fan based on the extraction requirements of the room. For example, we suggest installing a fan that can provide at least 15 air changes per hour, meaning that the air in the room is removed 15 times every hour. You can calculate this by multiplying the LxHxW of the room in meters which gives you the volume, and then multiplying that figure by 15. This will give you the recommended minimum airflow capacity in ‘cubic meters per hour’ (m3/hr) you need to meet or exceed when looking for a fan.
