THE RIGHT WINDOWS FOR VENTILATION

The placement of your windows will determine whether you need panes with larger or smaller openings. While your architect will advise you on this, it’s still up to you to choose the most suitable style of window. Different rooms in your home will also have different ventilation needs. Because of this, it’s essential to understand how each type of window offers or limits the ventilation in your home.

It’s also important to remember window openings can be restricted for regulatory reasons.

This restriction will limit the amount of air flow coming in and out of your home. To counteract windows with regulatory restriction in a particular room, you may need to reconsider the types or amount of windows you choose for that particular area.

SLIDING WINDOWS

Sliding windows don’t protrude when they’re opened, so they’re ideal for assisting ventilation in areas with limited inside and outside opening space.

Sliding windows are also easily combined with insect or security screens without compromising your ventilation.

In rooms that require plenty of ventilation (such as bathrooms), sliding windows can be ordered with a vent lock. This allows you to lock the window at different opening points along the track for security and total control over your ventilation.

It’s important to keep in mind that for sliding windows, only half (sometimes less) of the window can be opened for ventilation. This restriction limits the volume of natural airflow. And in other cases, the opening can be more than half (like in the case of a sliding window with three panels – two sliding and one fixed). This allows for extra air flow in a room that needs lots of ventilation.

AWNING WINDOWS

Like sliding windows, awning windows can be placed in areas with limited opening spaces.

They can also be combined with insect or security screens for secure ventilation.

In most cases, awning windows have significantly smaller openings than sliding windows. Because of this, awning windows are most appropriate for rooms that require less ventilation. They’re also ideal for areas where your home’s design needs windows with smaller openings to encourage the ventilation process.

As they can be left open during light rain, awning windows can provide ventilation in situations where other window cannot. So even awning windows have their place in a naturally ventilated home.

DOUBLE HUNG WINDOWS

Double Hung windows offer particular control over your ventilation.

That’s because you can choose to invite air into your home through the top of the window, the bottom, or both by moving each of the two window sashes as desired.

Like sliding and awning windows, double hung windows are ideal for restricted opening spaces. They can also be combined with insect or security screens for increased security without affecting airflow. (However, it’s worth noting that this makes them difficult to clean, some types of screens cannot be removed.)

BI FOLD WINDOWS

If you want maximum ventilation, you can’t look past bi fold windows.

These windows fold all the way back to provide a large opening area that’s almost the size of the window frame itself.

Unlike the other window options, there are limited screening options for bi-fold windows. Because they protrude to the width of each panel on the outside, bi-fold windows can only be installed in areas with room for large opening spaces.

CASEMENT WINDOWS

Casement windows are another style of window designed for maximising ventilation in your home.

Thanks to their wide opening arc and how they open, casement windows allow you to control and divert breezes from different directions into your home. It’s these two features that account for why they’re one of two window types recommended by the Australian government for maximising air movement in your home.

Casement windows are known to be difficult to screen, but Bradnam’s Windows and Doors has released a screenable casement window offering a modern look that provides security and protection from the outside world.

LOUVRE WINDOWS

The other window type recommended by the government for encouraging airflow in your home is louvre windows.

With the ability to open out to be as much as 95%, louvre windows are ideal for encouraging ventilation in your home. Their variable opening angles also allow you to control and direct this ventilation as desired and required. Importantly, while second storey louvre windows have restricted openings for safety (much like most other types of windows), they still invite plenty of ventilation into your home.

FIXED WINDOWS

Due to their fixed nature, fixed windows do not contribute to natural ventilation in your home.

While they’re ideal for light, views, and architectural accents, they’re not useful for ventilating your home.

MAKE INFORMED CHOICES

Choosing windows is a task that should be done in consultation with your architect or builder, or with one of our consultants.

Now that you know about different windows and their ventilation potential, you’ll be able to make better informed choices.

Choosing the right windows and doors can be a challenge, especially if you’re new to the process. Our selection guideline will help you find the correct windows and doors for your project.
