Sliding Window | H1200 x W2400

An aluminium sliding window measuring 1200mm high by 2400mm wide is a wide-format residential window engineered for open-plan living rooms, dining areas, master bedrooms, and entertainment rooms. Standing at 1.2 metres tall by 2.4 metres wide, this H1200 x W2400 unit features two horizontal sashes that glide smoothly along an integrated track to deliver panoramic outdoor views and controlled airflow. Built from heavy-duty Australian aluminium, it provides dependable weatherproofing, low-maintenance operation, and clean architectural sightlines for modern home renovations and new residential builds.

Why Choose an H1200 x W2400 Sliding Window?

When you are designing an open-plan living area or a master bedroom that looks out over a garden or patio, an H1200 x W2400 sliding window offers a superb balance of natural daylight, ventilation, and interior layout flexibility. The expansive 2400mm width opens up your wall to panoramic views without requiring floor-to-ceiling glass. This horizontal span brightens large interior spaces instantly, creating an airy and welcoming atmosphere for family living and indoor entertaining.

The 1200mm height is an exceptionally practical vertical dimension because it leaves plenty of wall space beneath the window sill. You can position couches, buffets, desks, or bedroom furniture directly beneath the glass without blocking your view or obstructing airflow. Because the window sashes slide horizontally inside the frame track, the unit never projects outward over outdoor decks, walkways, or garden beds when open. Inside your home, the sliding sash stays completely clear of curtains, roller blinds, and plantation shutters, giving you effortless ventilation and uncluttered architectural proportions.

Built for Australian Climate & Lifestyle

We engineer this H1200 x W2400 aluminium sliding window to withstand extreme Australian weather conditions and demanding daily use. Wider 2400mm frames require superior torsional rigidity, so our aluminium profiles feature reinforced mullions and heavy-duty bottom tracks designed to maintain their structural shape over decades of operation. Whether your property faces coastal salt air or hot western Sydney summers, the powder-coated finish will not rot, warp, or swell over time.

This wide-format window is a staple for modern Australian indoor-outdoor living. Unlike timber window frames that can absorb moisture and require regular sanding and repainting, powder-coated aluminium remains completely stable and low-maintenance. A quick periodic wipe of the sill and tracks is all you need to keep the nylon rollers moving smoothly year after year.

How to Configure Your H1200 x W2400 Window

You can customise every functional aspect of your window directly on this page to match your architectural plans. For contemporary architectural builds and modern extensions, Custom Black powder coating creates a crisp, high-contrast outline around your outdoor view. Traditional brick or rendered properties often look best with Pearl White for a classic, clean aesthetic.

Because an H1200 x W2400 window features a substantial 2.88 square metres of glass surface area, your glazing choice makes a meaningful difference to daily indoor comfort. Standard clear toughened glass works well for shaded side yards and covered patios. If your window faces north or west and receives direct afternoon sun, upgrading to Low-E glass or Double Glazing helps keep your living room or bedroom cooler in summer while reducing your household heating and cooling costs. You can also add custom insect flyscreens or stainless steel security screens so you can leave your window open for cooling breezes with total peace of mind.
