Architectural Aluminium Awning Window | H900 x W1800

The H900 x W1800 architectural aluminium awning window is a sweeping, panoramic horizontal unit engineered to deliver expansive sightlines alongside versatile, all-weather cross-ventilation. Measuring 900mm in height and stretching a massive 1.8 metres across, this wide-format frame intelligently pairs solid stationary glass panels with premium, push-out awning sashes. It is the definitive glazing solution for contemporary Australian homes, providing an exceptional architectural feature for expansive kitchen splashbacks, high-wall clerestory placements, and luxury bathrooms where you demand immersive natural light and total climate control without completely sacrificing valuable lower wall space.

The Architectural Logic of the 900x1800 Horizontal Format

Selecting precisely engineered, large-scale window dimensions can fundamentally transform the spatial dynamics, exterior aesthetics, and daily interior comfort of your property. The 900mm height by 1800mm width format is a highly sought-after and deeply practical measurement in modern Australian residential construction. When installed in a kitchen, for example, a 900mm high window placed directly above standard 900mm cabinetry perfectly aligns with typical lintel heights, creating a seamless, highly functional glass splashback that floods your workspaces with light.

A width of 1800mm makes a bold, undeniable architectural statement. It acts as a cinematic glass landscape that seamlessly erases the boundary between your indoor living space and your exterior environment. However, constructing a single, fully operable 1.8-metre wide awning sash is structurally impractical and aesthetically heavy. The immense weight of a single pane of that size would place impossible strain on the hinges, winders, and perimeter seals over time.

The true brilliance of this expansive unit lies in its multi-panel design. By intelligently dividing this massive 1.8-metre opening into distinct vertical sections, such as a large central fixed picture pane flanked by two operable awning sashes, or a clean, symmetrical 50/50 split configuration, we deliver the absolute best of both structural worlds. The expansive fixed sections remain completely free of heavy mechanical hardware, giving you a crystal-clear, high-definition sightline to your garden or alfresco area. The operable awning panels deliver essential climate control. Because awning sashes hinge at the top and push outward from the bottom, they create a protective exterior glass canopy. This unique mechanism allows you to catch passing coastal breezes and flush trapped hot air out of your house, even when a sudden rain shower is passing through, without compromising the sleek, modern aesthetic of the wide frame.

Room by Room Application Guide

Architects, premium builders, and discerning homeowners consistently specify this wide, 1.8-metre multi-panel frame when they want to maximize natural light and passively control the indoor temperature on a large scale. The sweeping horizontal proportions provide a serious architectural advantage for rooms that endure heavy daily use.

Expansive Kitchen Splashbacks and Sculleries Installing this 1.8-metre wide, 900mm high window directly above your kitchen benchtops creates a breathtaking, well-lit food preparation space. It acts as a cinematic frame for your side yard, allowing you to watch the kids play outside while you cook. The flanking awning sashes allow you to instantly vent steam, smoke, and strong cooking odours directly outside, drastically reducing your reliance on loud, energy-heavy exhaust canopies. Because the sashes push outward, they form a shield against light rain, keeping your kitchen dry while maintaining essential cross-ventilation.

Architectural Clerestory & High-Wall Living Areas Hot air naturally rises to the ceiling. Placing this sweeping 1.8-metre wide window high up on a raked ceiling or along the top of a living room wall creates an incredibly effective thermal chimney. This is a vital strategy in passive solar house design. You can open the awning sashes on a blistering summer afternoon to let trapped heat escape entirely, which actively draws cooler replacement air in from the lower windows in the house. The high placement gives you massive, whole-house airflow while maintaining total visual privacy from your neighbours.

Primary Bathrooms and Grand Ensuites Wet areas fundamentally demand excellent cross-ventilation to prevent condensation, peeling ceiling paint, and structural black mould. Installing this wide window in a grand family bathroom allows hot shower steam to escape rapidly. The 900mm height leaves plenty of lower wall space for a freestanding bathtub or a double vanity unit. When you configure this 1.8-metre window with our Satinlite Obscure glass, the textured surface diffuses the incoming light entirely. You guarantee total visual privacy for your family while keeping the bathroom incredibly bright, dry, and airy all day long.

Customising Your Glazing and Finish

A window of this immense horizontal scale allows a highly significant amount of solar energy into your property. The glass you choose plays a major, foundational role in your daily thermal comfort and ongoing seasonal energy bills. We build your windows entirely to order so you get the exact thermal performance your specific geographical location requires.

Standard Clear glass is a highly cost-effective choice for well-shaded boundary walls, deep covered patios, or southern elevations where direct sunlight is naturally limited. If this massive wide window faces the brutal western afternoon sun, standard glass will trap the heat and quickly turn your living space into a greenhouse. We strongly recommend upgrading to Low-E glass or a Grey Tint for these highly exposed locations. Low-E glass features a microscopic, transparent metallic coating that actively reflects radiant heat back outside. It stops your rooms from overheating during intense summer heatwaves and actively retains your expensive interior heating during the freezing winter months.

For the highest possible level of energy efficiency and acoustic performance, select our Double Glazed upgrade. Double glazing traps an insulating pocket of inert argon gas between two completely separate glass panes, creating a massive thermal and acoustic barrier right in the middle of your wall. This is a brilliant solution for homes positioned near busy roads or noisy neighbourhood spaces.

We protect all our heavy-duty aluminium frames with a tough, baked-on powder coated finish that actively resists chalking, fading, and coastal saltwater corrosion over decades of constant use. Pearl White remains a classic choice for traditional brick builds because it actively reflects heat away from the frame. Custom Black delivers a bold, striking border that highlights contemporary architecture perfectly. Our Custom Colour service is available if you need to match existing window frames precisely during a major home extension.

Internal Security and Screening Solutions

Because awning windows push outward from the bottom, all protective insect and security screens must be mounted directly on the inside of the frame. This provides a massive aesthetic and practical advantage. Mounting the screens internally keeps them completely protected from the harsh outside weather, meaning they stay significantly cleaner, avoid exterior debris buildup, and last much longer than externally mounted screens.

The primary aesthetic advantage of a multi-panel layout is that you only ever need to screen the designated ventilation zones. Your massive fixed picture panes stay completely free of mesh, providing an ultra-clear, high-definition view. A standard internal Flyscreen keeps mosquitoes and flies away during warm summer nights. If you want genuine, uncompromising peace of mind, upgrade to our heavy-duty Stainless Steel Security Screens. This premium woven mesh resists knife attacks, heavy blunt impact, and forced entry attempts, allowing you to ventilate your home safely at any hour of the day or night.

Frequently Asked Questions

Can awning windows really stay open when it rains? Yes. One of the greatest architectural advantages of the awning window design is that the glass sash hinges at the top and pushes out at the bottom. This creates a natural glass canopy that effectively deflects light-to-moderate rain away from the opening, allowing you to keep your room actively ventilated even during a downpour without soaking your internal sills or flooring.

Are the chain winders secure for ground-level installations? Absolutely. Our premium heavy-duty chain winders feature a fully integrated key lock. You can wind the window out to your desired ventilation gap and securely lock the winder in place with a key. This provides excellent security, preventing the window from being forced open further from the outside by intruders.

What is the standard manufacturing lead time for this 900x1800 frame? We build this large architectural unit entirely to order based on your chosen frame colour, glass type, and panel configuration. Our standard manufacturing lead time is typically 12 to 15 working days from the date of your order. Our production team will keep you informed throughout the build process and arrange a specific delivery date once the unit passes our final, strict quality control checks.
