G'day! You're in the middle of a reno and you've hit a snag. You have a bathroom, laundry, or kitchen that desperately needs good ventilation to fight off steam and mould, but there's a problem. Maybe it's a ground-floor room with another storey above it, or you're in an apartment with a solid concrete ceiling. There's simply nowhere to run the ducting for a standard ceiling fan.

So, what do you do? Don't stress, mate. It's time to look at a clever, and somewhat old-school, solution: the window exhaust fan.

So, What is a Window Exhaust Fan?

A window exhaust fan is a compact ventilation unit that is designed to be mounted directly into a hole cut in a pane of glass.

Instead of needing a ceiling or wall cavity to run ducting, this fan vents the stale, moist, or smelly air directly to the outside through the window it's installed in. It’s a brilliant, straightforward solution for rooms where conventional fan installation is impossible.

When is a Window Fan the Ripper Choice?

A window-mounted fan is the perfect problem-solver in a few specific scenarios common in Aussie homes:

In Rooms with No Wall or Ceiling Access

This is the number one reason to choose a window exhaust fan. They are the go-to for:

• Ground-floor bathrooms or laundries in two-storey brick homes.
• Apartments and units with concrete slab ceilings.
• Rooms with flat roofs or cathedral ceilings that have no accessible roof cavity.

For Direct, At-Source Kitchen Extraction

In some smaller kitchens or commercial settings, a window fan placed near the cooktop can be a very effective way to pull cooking smoke and odours straight outside before they have a chance to spread through the house.

In Older or Uniquely Built Homes

You'll often see these in older brick homes that were built before modern ceiling fans became the standard. They are a proven, reliable way to add ventilation to a structure that wasn't originally designed for it.

What to Look For When Buying

• Airflow (Extraction Rate): Like any fan, its power is measured in cubic metres per hour (m³/hr). Make sure you choose a fan that's powerful enough for the size of your room.
• Reversible Functionality: This is a beauty! Many window fans have a reversible switch. This means on a hot day, you can flick a switch to turn it from an exhaust fan sucking stale air out, to an intake fan drawing fresh, cool air in.
• Weatherproof and UV-Resistant Design: A window exhaust fan lives in your window, constantly exposed to the Aussie sun and rain. It's crucial that it's made from high-quality, UV-stabilised plastic to prevent it from going brittle and cracking, and that it has a good weatherproof seal.

Installation: This is a Job for Two Professionals

This is one job that is absolutely, 100% not for DIYers. Installing a window exhaust fan is a two-part process that requires two different sets of professional skills.

1. The Glazier: First, a qualified glazier needs to come and professionally cut a perfect, clean hole in your glass window pane. This is a specialised skill to avoid shattering the glass.
2. The Licensed Electrician: Second, a licensed electrician must then install the fan into the prepared hole and hardwire it into your home’s 240V power supply.

Attempting any part of this yourself is incredibly dangerous and likely to end with a broken window and a serious electrical hazard.
