H1200 x W3000 Aluminium Slide / Fixed / Slide Window

The H1200 x W1200 aluminium slide, fixed, and slide window is a massive three metre wide architectural unit built to maximize natural light and capture heavy airflow. It features a large central fixed glass panel flanked by two independent sliding sashes on either side. This symmetrical three-panel configuration makes it the perfect solution for wide living room walls, large outdoor entertainment serveries, or any space where you need completely unobstructed panoramic views alongside highly controllable ventilation.

The Engineering Behind the Three Metre Span

Installing a window that is three metres wide completely changes the dynamic of a room. It essentially replaces a solid wall with a sweeping glass display. However, managing a piece of glass this large requires very specific structural engineering.

If you tried to build a standard two-panel sliding window at this exact width, each glass panel would measure 1.5 metres across. That creates an incredibly heavy moving sash that places immense strain on the bottom rollers and track system. By splitting the three metre span into a slide, fixed, and slide configuration, we distribute the weight perfectly. The centre of the window becomes a dedicated, heavy-duty fixed picture window. The left and right sides house the operable sliding sashes.

This specific layout gives you the best possible balance of aesthetics and functionality. You get a massive, uninterrupted sightline right through the middle of the frame where you look the most. At the same time, two people can operate the outer sashes independently. You can open one side to catch a gentle morning breeze, or slide both outer sashes fully open to flush hot air out of a large living space rapidly.

Ideal Placements for Large Australian Homes

Builders and homeowners specify this massive three metre frame when they want to make a serious visual impact. The H1200 height provides a generous vertical viewing area while leaving room below for furniture, heating units, or kitchen cabinetry.

Open Plan Living and Dining Areas A three metre wide window acts as a brilliant glass wall in an open plan space. It completely opens up a dark living room and creates a strong visual connection to your backyard or garden. Because you can open both ends simultaneously, this window excels at creating cross-ventilation. It draws fresh air right across your living space to cool the house naturally on a hot summer afternoon.

Alfresco Serveries and Kitchens This specific configuration is highly popular for indoor and outdoor entertainment areas. If you install this window flush with your kitchen benchtop, it functions as a massive servery. You can slide the outer sashes open and pass food, drinks, and plates directly out to your patio or barbecue area. The wide central fixed pane protects your kitchen prep area from the wind while keeping you visually connected to your guests outside.

Master Bedrooms and Rumpus Rooms Large bedrooms and dedicated rumpus rooms need plenty of natural light to feel inviting. This window floods large spaces with morning sun. The dual sliding sashes give you total control over the temperature. You can crack the windows slightly for a cool overnight breeze, knowing the key-lockable handles keep the sashes securely fixed in place.

Customising Your Glazing and Finish

Three square metres of glass is a significant thermal bridge. The type of glass you select will heavily dictate how hot or cold your room feels throughout the year. We build every window to order so you can choose the exact thermal performance your location requires.

Standard Clear glass is a great cost-effective choice for heavily shaded patios or southern facing walls where direct sunlight is not an issue. If this large window faces the harsh western sun, standard glass will quickly turn your living room into an oven. For these exposed locations, we strongly advise upgrading to Low-E glass or a Grey Tint. Low-E glass features a microscopic coating that actively reflects radiant heat. It bounces summer heat back outside and helps retain your internal heating during the winter months.

For the highest level of energy efficiency, you need our Double Glazed units. Double glazing traps an insulating pocket of argon gas between two separate glass panes. This setup creates a massive thermal barrier that significantly lowers your air conditioning costs while simultaneously blocking out loud traffic noise.

We finish all our aluminium frames in a highly durable, baked-on powder coating. This finish actively resists fading, chalking, and coastal corrosion. Pearl White is a classic, heat-reflective choice that suits traditional Australian homes. Custom Black provides a striking, high-contrast border that frames your outside view like a modern photograph. If you need a specific architectural match, our Custom Colour service ensures your new window blends perfectly into your building project.

Internal Security and External Screening

Unlike awning windows, sliding windows feature screens mounted on the outside of the track. Because the central pane is fixed, you only need to screen the two outer sliding sections. This is a massive aesthetic advantage. The large central picture window remains completely free of mesh, giving you a crystal clear, unobstructed view of your property.

Our window profiles include integrated external tracks to hold these screens securely. If you simply want to keep flies and mosquitoes out during summer, our standard Flyscreens do the job perfectly. If you want true peace of mind, upgrade to our Stainless Steel Security Screens. This heavy-duty woven mesh resists knife attacks and forced entry attempts. It allows you to leave both sides of your three metre window wide open on a hot night while keeping your family totally secure inside.

Built to Meet Australian Standards

The Australian climate destroys cheap building materials very quickly. We build our products to survive extreme heatwaves, driving rain, and strong winds without warping or leaking. Every aluminium window we manufacture complies strictly with AS 2047 building standards. This certification means your specific window design has passed rigorous laboratory testing for structural deflection, operating force, and water penetration resistance.
