Awning & Casement Windows Guide Melbourne (2026)
What Are Awning Windows?
Awning windows are hinged at the top and open outward from the bottom, typically operated by a winder or crank handle — which is why they are also commonly called wind out windows. As the handle turns, a scissor arm or friction stay pushes the sash outward to a controlled angle, holding it firmly in place even in breeze.
The defining characteristic of awning windows is their geometry when open: the sash angles downward, meaning the glass itself acts as a shield that deflects rain away from the opening. This is the reason a bathroom awning window is the standard choice across Australian homes — you get continuous ventilation to remove steam and moisture without having to close the window every time it rains.
Modern awning windows are available in uPVC, aluminium awning windows, and timber. Of these, uPVC double glazed awning windows deliver one of the best thermal performance and the lowest lifetime maintenance cost — a key consideration for Melbourne’s variable climate.
- Hinged at top, open from bottom outward
- Operated by winder (wind out) or push bar
- Rain protection when open — unique to this style
- Ideal for high-placement openings for privacy with ventilation
- Night-vent striker plate for millimetre-gap secure overnight ventilation
- Compatible with retractable fly screens
💡 Most popular style in Australia
Casement and awning windows are the most widely used window style in Australia. Their outward-opening design, tight seal when closed, and compatibility with double glazing make them the default choice for new builds and window replacements alike.
What Are Casement Windows?
Casement windows are hinged at the side and swing fully outward like a door. Unlike awning windows, the entire sash area opens — making casements the preferred choice wherever maximum airflow is the priority. Their unobstructed glass pane (no horizontal mid-rail) also delivers clear, panoramic views and excellent natural light, which is why modern casement windows are a popular choice for living rooms and home offices.
In Melbourne, uPVC casement windows use multi-point espagnolette locking hardware — the handle engages multiple locking bolts simultaneously around the frame, creating both a highly secure window and an extremely tight compression seal for thermal and draught performance. This makes uPVC casement windows significantly more airtight than standard aluminium casement windows, which rely on single-point or basic compression seals.
A French casement configuration — two sashes hinged on their outer edges, meeting in the centre — is also available, offering a wide, unobstructed opening and a striking contemporary look that suits modern awning windows and casement pairings in open-plan homes.
- Hinged at side, opens fully outward (like a door)
- Full sash opening = maximum ventilation
- Unobstructed glass for panoramic views
- Suitable as emergency egress window
- Available with colonial bar grilles for period homes
- French casement option for wide openings
Casement and Awning Windows: Head-to-Head
Both styles are outward-opening, both work with double glazing, and both are excellent choices for uPVC frames. The right pick comes down to the specific needs of each room and opening.

Double Glazed Awning Windows: Why They Matter in Melbourne
Double glazed awning windows combine the practical advantages of the awning style with the thermal and acoustic benefits of two glass panes separated by a sealed, gas-filled cavity. For Melbourne homes — where winter mornings can be frigid and summer afternoons brutal — this combination addresses both comfort and running costs simultaneously.
The performance of a window is measured by its U-value (heat transfer rate — lower is better). A standard single-pane aluminium awning window sits at around 5.0–6.0 W/m²K. A uPVC double glazed awning window with argon gas fill achieves 1.4–1.6 W/m²K — more than three times better. Premium triple glazed units reach as low as 0.9 W/m²K.
The same principle applies equally to awning double glazed windows used in casement configurations — the uPVC frame plus double glazed unit combination is what drives the performance, regardless of whether the sash is top-hinged or side-hinged.
🏡 NCC 7-Star Minimum Standard
Since 2023, all new Australian homes must achieve a minimum 7-star NatHERS energy rating. Double glazed awning windows with uPVC frames are one of the most effective tools for meeting this requirement in Melbourne’s heating-dominated climate zone.
uPVC vs Aluminium Awning Windows: Which Is Better?
Aluminium awning windows have dominated the Australian market for decades — they are widely available, cost-effective upfront, and structurally strong. But aluminium has a fundamental weakness: it is an excellent conductor of heat. In winter, an aluminium frame rapidly transfers warmth from inside your home to the cold outside air. In summer, it works in reverse. This makes aluminium window awnings a significant source of energy loss regardless of the quality of the glass unit.
uPVC awning windows solve this problem at the frame level. The multi-chamber uPVC profile traps still air inside the frame, creating a thermal barrier that conducts heat at roughly 1/1,000th the rate of aluminium. Combined with double glazing and warm-edge spacer bars, a uPVC awning window in Melbourne delivers dramatically better whole-window thermal performance.
| Factor | uPVC | Aluminium | Timber |
|---|---|---|---|
| Thermal performance | ✔ Excellent | ✘ Poor | ◑ Good |
| Frame cost per m² | $300–$500 | $300–$1,250 | $600–$1,500 |
| Maintenance required | Minimal — wipe clean | Low–moderate | High — paint & seal regularly |
| Coastal corrosion resistance | ✔ Excellent | ✘ Poor untreated | ✘ Poor |
| Lifespan | 25–35+ years | 20–30 years | 15–25 years |
| Termite resistance | ✔ Yes | ✔ Yes | ✘ Susceptible |
| Colour options | Main colours | Powder coat range | Multiple |
| Noise reduction | Up to 47 dB (double glazed) | Moderate | Moderate |
Awning Window Fitting Costs in Melbourne (2026)
The cost of awning window fitting in Melbourne depends on the frame material, glass specification, window size, and whether you are replacing existing windows or installing in new construction. uPVC double glazed units sit in the mid-range — more than basic aluminium single-glazed, but significantly less expensive over their lifetime when energy savings and zero maintenance are factored in.
| Window Type & Specification | Supply Only | Supplied & Installed |
|---|---|---|
| Awning — white uPVC, double glazed (air fill) | $500–$700 | $800–$1,100 |
| Awning — white uPVC, double glazed argon | $600–$900 | $900–$1,300 |
| Awning — custom colour, double glazed argon | $700–$1,100 | $1,000–$1,500 |
| Casement — white uPVC, double glazed argon | $650–$950 | $950–$1,500 |
| French Casement — double glazed argon | $1,400–$2,000 | $2,800–$3,500 |
| Any style — triple glazed | 10-15% more | 10-15% more |
| Whole home — 3-bedroom (10–15 windows) | $15,000–$40,000 total | |
💰 Cost tip
Replacing all windows in a single job significantly reduces per-window labour costs. Mixing window types — fixed frames where ventilation is not needed, awning or casement where airflow matters — is the most cost-effective approach for a whole-home upgrade in Melbourne.
Maintenance & Longevity
One of the strongest arguments for uPVC over aluminium awning windows or timber casement windows is the near-zero maintenance requirement. No painting, sanding, sealing, or corrosion treatment is ever needed. Annual care is simple: wipe frames with mild soapy water, lubricate winders and hinges, and check rubber perimeter seals for any compression damage. Most quality uPVC awning windows in Melbourne carry a 10-year frame warranty and 7–10 years on the sealed double glazed unit.
People Also Ask
The most commonly searched questions about awning windows and casement windows — answered directly.
What is the difference between awning and casement windows?
Awning windows hinge at the top and open from the bottom — they can stay open in rain. Casement windows hinge at the side and open fully outward for maximum ventilation, but must be closed in wet weather.
Are aluminium awning windows good?
Aluminium awning windows are durable and cost-effective upfront, but aluminium is a poor thermal insulator — it conducts heat rapidly, increasing energy costs. uPVC awning windows outperform aluminium significantly on energy efficiency.
What are wind out windows?
Wind out windows are awning or casement windows operated by a winder handle that cranks the sash open. The winder controls the opening angle and holds the sash securely in position. All uPVC awning windows from Windows Republic use winder operation.
Which window is best for a bathroom?
A bathroom awning window is the standard choice — it can be positioned high for privacy, left open during rain to exhaust steam, and set to a tiny gap overnight using a striker plate for continuous secure ventilation.
Do awning windows come in modern styles?
Yes. Modern awning windows in uPVC feature slim sight lines, near flush external profiles, and various colour options including black, grey, and woodgrain foils — complementing both contemporary and heritage Melbourne homes.

Frequently Asked Questions
What are awning windows?
Awning windows are hinged at the top and open outward from the bottom via a winder or crank handle. The sash angles downward when open, deflecting rain away from the opening — meaning you can leave them open during light rain. They are one of Australia’s most popular window styles, particularly for bathrooms, kitchens, and laundries where continuous, weather-safe ventilation is needed.
What is the difference between awning windows and casement windows?
Awning windows are hinged at the top and open outward from the bottom — ideal for rain-safe ventilation. Casement windows are hinged at the side and open fully outward like a door, providing maximum airflow and an unobstructed glass pane for panoramic views. Both are excellent when fitted with uPVC double glazed frames.
How much do double glazed awning windows cost in Melbourne?
Double glazed awning windows in Melbourne typically cost $2,2=000–$3,200 per installed window. Custom colours, Low-E glass, or triple glazing increase the price. A whole-home replacement across a 3-bedroom house typically costs $15,000–$40,000.
Are uPVC awning windows better than aluminium awning windows?
For thermal performance, yes — significantly. uPVC awning windows conduct heat at roughly 1/1,000th the rate of aluminium, making them far more effective at reducing heat loss in winter and heat gain in summer. Aluminium awning windows remain durable and are a reasonable choice for budget-focused projects, but they cannot match the energy efficiency or lifetime maintenance savings of uPVC.
Can awning windows stay open in rain?
Yes — this is their primary advantage over casement windows. Because awning windows hinge at the top, the angled sash acts as a canopy that deflects rain away from the opening. This makes them the go-to choice for bathrooms, kitchens, and laundries in Melbourne homes. Casement windows are side-hinged and should be closed during wet weather.
What are wind out windows?
Wind out windows — also called winder windows or crank-out windows — are awning or casement windows operated by a winder handle. Turning the handle cranks the sash open to a set angle via a scissor arm or friction stay, which holds the window firmly in place. uPVC wind out windows use corrosion-resistant hardware and require only annual lubrication to maintain smooth operation for decades.
What is the best awning window for a bathroom in Melbourne?
A uPVC double glazed bathroom awning window is the optimal choice. It can be positioned high on the wall for privacy, opened during rain without water ingress, and set to a tiny night-vent gap using the striker plate for continuous secure ventilation. The double glazed uPVC unit also prevents condensation forming on the glass — a common problem with single-pane aluminium bathroom windows.
What is awning window fitting?
Awning window fitting is the professional process of supplying and installing awning windows into a home or building. For uPVC awning windows in Melbourne, fitting includes precise measurement of each opening, removal of existing frames where replacing, installation of the new uPVC frame, fitting of the double glazed unit, hardware adjustment and testing, and weathersealing. A single window fitting typically takes 2-4 hours; a whole-home job of 12–15 windows is usually completed in 4-6 days.
Are aluminium casement windows worth buying in Melbourne?
Aluminium casement windows are a cost-effective option for projects where thermal performance is less critical — garages, outbuildings, or commercial spaces. For residential homes in Melbourne, where heating and cooling costs are significant, uPVC casement windows deliver substantially better energy efficiency, eliminating the thermal bridging that makes aluminium frames a weak point in an otherwise well-insulated home.
How long do uPVC awning and casement windows last?
Quality uPVC awning and casement windows in Melbourne last 25–35 years or more with minimal maintenance. They never need painting or sealing. Most reputable suppliers offer a 10-year manufacturer’s warranty on the uPVC frame and 5–10 years on the sealed double glazed unit.
Can double glazed awning windows reduce energy bills?
Yes. Double glazed awning windows with uPVC frames can reduce household energy bills by around 10-30%. The combination of the multi-chamber uPVC frame and the argon gas-filled sealed unit minimises heat transfer in both directions — keeping warmth inside in winter and solar heat outside in summer. Low-E glass coating amplifies this effect further by reflecting radiant heat without reducing natural light.
What colours are available for awning and casement windows?
uPVC awning and casement windows are available in various colours and finishes including white, black, anthracite grey, cream, silver, grey aluminium and woodgrain foils. Many Melbourne suppliers, including Windows Republic, allow you to specify different colours for interior and exterior faces — matching internal décor while achieving a specific look.
