H900 x W1200 Aluminium Awning & Fixed Window | Custom Built

The H900 x W1200 aluminium awning and fixed window is a highly practical, weather-resistant architectural unit measuring 900mm high and 1200mm wide. It features a stationary glass panel paired with an operable awning sash that pushes outward from the bottom. This combination makes it the ideal window for Australian kitchens, bathrooms, and laundries. You gain maximum natural light through the fixed pane while securing reliable, rain-protected ventilation through the awning section.

The Advantage of the 900x1200 Split Configuration

Getting the proportions right is an essential part of residential design. The 900mm by 1200mm rectangular dimension is a standard fixture in modern Australian construction. It provides a generous amount of glass surface area without demanding an entire wall. This specific size fits perfectly above standard bench heights or midway up a bedroom wall, leaving you plenty of usable space below for furniture or cabinetry.

Choosing a split configuration for this width is a very deliberate engineering choice. Creating a single 1200mm wide awning sash places a massive amount of weight on the top hinges and the bottom winding mechanism. Over time, that weight can cause the sash to drop and bind against the frame. By splitting the unit into a dedicated fixed panel and a narrower operable sash, we eliminate that stress. You get a solid picture window for clear sightlines, alongside a perfectly balanced awning sash that operates smoothly every single time you turn the handle.

The awning mechanism itself is incredibly well suited to the local climate. Because the glass pushes outward, it acts as a rigid canopy over the window opening. You can safely leave the window cracked open during a passing rain shower. The angled glass sheds the water directly outside, allowing fresh air to continue circulating through your home without ruining your interior floors or plasterboard.

Room by Room Application Guide

Builders and homeowners frequently specify the 900mm by 1200mm frame for several key locations around the house. It is large enough to drastically improve natural lighting while remaining compact enough for tight spaces.

Kitchens and Sculleries Installing this window directly above your kitchen sink creates a brilliant workspace. You get a clear view of your backyard through the fixed pane while you prep food or wash dishes. The awning sash allows you to instantly vent steam, smoke, and strong cooking odours directly outside, reducing your reliance on loud exhaust fans.

Bathrooms and Laundries Wet areas require constant, reliable airflow to prevent mould and mildew buildup. The 900mm height provides plenty of open ventilation space. If you select our Satinlite Obscure glass option, the textured surface diffuses the light completely. You maintain total privacy from the street and neighbouring properties, making it an excellent choice for a bathroom exterior wall.

Secondary Bedrooms and Studies If you have limited wall space in a smaller bedroom or home office, this rectangular unit is a perfect fit. It lets the morning sun inside while giving you secure airflow overnight. The awning sash can be locked into a partially open position, giving you peace of mind while you sleep.

Selecting Your Glass for Energy Efficiency

Your choice of glass will heavily dictate the thermal comfort of your room. We offer multiple glazing options to help you manage the Australian sun and lower your power bills.

Standard Clear glass works perfectly for shaded patios or southern elevations where direct sunlight is not an issue. If your window faces the harsh western or eastern sun, standard glass will trap the heat and turn your room into an oven. We strongly recommend upgrading to Low-E glass or a Grey Tint for these exposed locations. Low-E glass features a microscopic, transparent coating that actively bounces solar heat back outside. It drastically improves your thermal comfort in summer and retains your internal heating during winter.

For the highest level of energy efficiency and acoustic dampening, our Double Glazed units are unmatched. The design traps an insulating pocket of argon gas between two panes of glass. This creates a massive thermal barrier that stops heat transfer and significantly muffles loud street traffic.

Frame Finishes and Screen Security

We apply a premium powder-coated finish to all our aluminium frames to ensure they resist fading, chalking, and coastal corrosion. Pearl White is a classic choice that reflects heat and looks sharp on traditional builds. Custom Black delivers a striking, modern contrast that defines contemporary and industrial architecture. If you need to match existing hardware for a renovation, our Custom Colour service guarantees a precise match for your specific project.

Because the awning sash pushes outward to the exterior, any protective screen must be mounted on the inside of the room. Our window profiles are specially extruded to hold these internal screens flawlessly. The chain winder sits below the screen track or passes through a neatly engineered slot so you never have to remove the mesh to close the window. A standard Flyscreen keeps the bugs away during summer. If you want true peace of mind, upgrade to our Stainless Steel Security Screen. This heavy-duty mesh resists forced entry and impact, meaning you can leave the window open at night with total confidence.

Built to Meet Australian Standards

The local environment is notoriously harsh on building materials. We build our products to survive extreme weather conditions without warping, leaking, or rattling. Every window we manufacture complies strictly with AS 2047 building standards. This means the design has passed rigorous laboratory testing for structural deflection, operating force, and water penetration under high wind loads.

Correct installation guarantees the longevity of your window. We supply the unit fully assembled and ready for your carpenter or builder to install. The extruded aluminium frame is exceptionally rigid, which prevents the window from bowing out of square during the fitting process.

New Age Construction Group operates out of Smeaton Grange NSW, and we deliver our custom building materials right across Australia. If your building site is located in Sydney, Melbourne, Brisbane, Perth, Adelaide, or a regional town, we transport your custom windows safely and directly to your door.

Frequently Asked Questions

How do I clean the outside glass of an awning window? Because the sash pushes outward, cleaning the exterior glass requires outside access. For ground floor installations, you can simply wash the window from your yard. For second-story applications, you will need a ladder or an extendable window cleaning pole to reach the exterior pane safely.

Can I lock the window while it is open? Yes. Our premium chain winders come standard with a keyed lock built into the handle. You can wind the window open to your preferred ventilation point, turn the key, and lock the sash in place. The window cannot be forced wider from the outside, which provides excellent security while allowing fresh air into your home.

How long does manufacturing take for a custom size? We build every window entirely to order based on your exact colour, glass, and screen choices. Our typical lead time is 3 to 5 weeks from the date of purchase. Our production team will keep you informed of our progress and schedule a firm delivery date once your items are ready for transport.
