Sliding Window | H900 x W900

An aluminium sliding window measuring 900mm high by 900mm wide is a compact residential window designed for bathrooms, ensuites, laundries, and small kitchens. Standing at 900mm square, this H900 x W900 unit features horizontal sashes that slide smoothly along an integrated track to provide controlled ventilation and natural daylight. Built from heavy-duty Australian aluminium, it delivers dependable weatherproofing, low-maintenance operation, and clean architectural sightlines for renovations and new home builds.

Why Choose an H900 x W900 Sliding Window?

When you are designing smaller functional rooms in a residential build or renovation, an H900 x W900 sliding window offers a practical balance of airflow, privacy, and natural daylight. The square 900mm by 900mm dimensions make it an ideal choice for bathrooms and ensuites where you need ventilation to clear steam without sacrificing wall space for vanities, mirrors, or towel rails. It is also a popular size for laundries and walk-in pantries.

Because the window sashes slide horizontally within the frame, the window does not project outward over exterior pathways or narrow side yards. Inside the house, the sliding sash stays completely clear of blinds and interior shutters. You gain excellent airflow and uncluttered proportions in a low-maintenance design that operates smoothly for decades.

Built for Australian Climate & Lifestyle

We engineer this H900 x W900 aluminium sliding window to withstand tough Australian weather conditions and high-moisture indoor environments. Unlike timber frames that can swell or rot when exposed to bathroom steam or laundry humidity, our powder-coated aluminium profiles maintain their structural shape and pristine appearance over decades of daily use.

The compact square frame provides outstanding rigidity and structural integrity. Whether your property faces coastal salt air or hot western Sydney summers, the weather seals and internal drainage channels ensure reliable protection against wind-driven rain. It is a low-maintenance window solution that requires only an occasional wipe of the tracks to keep the rollers moving freely.

How to Configure Your H900 x W900 Window

You can customise every functional aspect of your window directly on this page to match your building plans. For contemporary architectural builds, Custom Black powder coating creates a sharp outline around your window opening. Traditional brick or rendered properties often look best with Pearl White for a classic, clean finish.

Glazing choice is particularly important for this compact window size. If you are installing an H900 x W900 window in a bathroom, ensuite, or laundry, upgrading to Satinlite Obscure glass gives you complete visual privacy while still flooding the room with natural daylight. You can also add custom insect screens or stainless steel security screens so you can ventilate your home safely.
