Choosing the right windows is about more than just curb appeal. In Perth, where we juggle scorching summer heat, strong coastal breezes, and wet winters, functionality is key. Whether you are planning a full renovation or building your dream home, the debate often comes down to two contenders: awning windows vs sliding windows.
Both styles have distinct advantages, but how do they stack up regarding airflow, security, and energy efficiency?
At Penot, we understand that every home is unique. This guide breaks down the pros and cons of each style to help you decide which is the best window type for your lifestyle.
Understanding the Basics
Before comparing performance, let’s clarify how each window operates.
What Are Awning Windows?
Awning windows are hinged at the top and open outward from the bottom, typically operated by a winder or friction stays. Their design creates an “awning” effect when open, providing a shield against the elements. They are a staple in modern WA designs due to their sleek look and superior sealing capabilities.
What Are Sliding Windows?
Sliding windows function horizontally, with one sash gliding past the other on a track. They are one of the most common window types in Australia because they are reliable, easy to operate, and do not protrude outward, making them a space-saving solution for walkways.
Climate Considerations for Perth Homes
Perth’s climate requires windows that can handle the “Fremantle Doctor,” high UV ratings, and storm seasons. Here is how each type performs.
Ventilation and Airflow
- Awning Windows: Excellent for controlled ventilation. You can keep them partially open to let hot air escape without worrying about sudden gusts slamming them shut. However, the sash can slightly deflect direct breezes rather than capturing them fully.
- Sliding Windows: Superior for maximum airflow volume. When fully open, the large unobstructed gap allows cooling breezes to flush out hot air rapidly, ideal for cooling a home down quickly in the evening.
Rain and Wind Resistance
- Awning: The clear winner for wet weather. The top-hinged design allows you to keep the window open during light rain showers, as the glass deflects water away from the opening.
- Sliding: generally must be closed during rain to prevent water entry. Additionally, the bottom tracks can accumulate Perth’s sandy dust, requiring regular vacuuming to ensure drainage slots don’t block during downpours.
Energy Efficiency
- Awning: When closed, the sash is compressed tightly against the frame. This compression seal virtually eliminates drafts, making them highly energy-efficient.
- Sliding: These rely on brush seals to bridge the gap between the moving sash and the frame. While modern engineering is effective, they generally have slightly lower thermal and sound insulation performance compared to the tight seal of an awning window.
Comparing Key Features
Here is a quick side-by-side comparison of how these windows perform.
| Feature | Awning Windows | Sliding Windows |
|---|---|---|
| Ventilation | Constant (usable during rain) | High Volume (maximum airflow) |
| Security | High (restricted opening size) | Medium (requires quality locks) |
| Cleaning | Moderate (outside access often needed) | High (easy access to tracks/glass) |
| Space Use | Protrudes outward | Zero protrusion (space-saving) |
| Sealing | Excellent (compression seal) | Good (brush seal) |
| Cost | $$-$$$ | $-$$ |
Which Window Style is Right for Your Home?
The “best” window often depends on the specific room it serves.
For Kitchens and Bathrooms
- Kitchens: If your window faces an alfresco area, a sliding window is ideal as it can act as a servery pass-through. However, for windows behind a sink, an awning window with a winder is ergonomically better, as it is easier to wind a handle than to lean over a tap to slide a sash.
- Bathrooms: Awning windows are the top choice here. They can be placed high for privacy while remaining open to vent steam, even during rainy weather.
For Bedrooms and Living Areas
- Bedrooms: Security and overnight airflow are priorities. Awning windows restrict the size of the opening, making it difficult for intruders to enter, allowing you to sleep safely with the window ajar.
- Living Areas: For capturing wide views or connecting to the backyard, sliding windows are superior. They minimise visual obstruction (fewer frames interrupting the view) and maximise natural light.
Renovations vs New Builds
If retrofitting, you may be limited by the shape of existing openings. Sliding windows are often wider than they are tall, while awning windows are flexible in shape. For new builds, a popular trend is mixing both, sliders for large spans and awnings for targeted ventilation.

Can You Use Double Glazing with These Window Types?
Absolutely. Double glazing is highly recommended for both styles to combat Perth’s heat.
Benefits for Awning Windows
Since awning windows already possess a superior compression seal, adding double glazing turns them into a powerhouse for thermal insulation. This combination is arguably the most effective way to reduce street noise and lower energy bills.
Benefits for Sliding Windows
Double glazing adds significant weight to the glass. For sliding windows, this necessitates high-quality rollers to ensure the sash glides smoothly. At Penot, our double glazed sliding windows are engineered with heavy-duty hardware to handle this weight effortlessly, ensuring you get thermal benefits without sacrificing ease of use.

Frequently Asked Questions
Which windows are cheaper: awning or sliding? Generally, sliding windows are more cost-effective. They use a simpler operating mechanism compared to the winders, friction stays, and compression seals required for awning windows. However, price varies based on size and glazing options.
Can I use flyscreens or security screens? Yes, but the setup differs.
- Sliding windows: Screens are installed on the outside, which is standard and very easy to use.
- Awning windows: Because the window opens outward, screens must be installed on the inside. This usually requires a special winder system or retractable screens to allow you to operate the window without removing the screen.
Which window is easier to clean? Sliding windows are typically easier to clean, as the moving sash can often be lifted out of the track, allowing you to clean both sides of the glass from inside the home. Awning windows, especially those on a second storey, may require a ladder or specialised “easy-clean” hinges to access the external glass surface.
Which type is better for soundproofing? Awning windows generally offer better acoustic performance. The compression seal around the frame blocks noise more effectively than the brush seals used on sliding windows.
Are awning windows good for ventilation? Yes, particularly in winter or wet seasons. They can remain open during rain, allowing continuous airflow without water entry, something sliding windows cannot do safely.
