Awning Window | H1200 x W900

An aluminium awning window measuring 1200mm high by 900mm wide is a versatile residential architectural window engineered for bedrooms, home studies, larger bathrooms, ensuites, stairwells, and kitchens. Standing at 1.2 metres tall by 900mm wide, this H1200 x W900 unit features a top-hung operable sash that swings outward from the bottom via a smooth, corrosion-resistant chain winder mechanism. Built from heavy-duty Australian aluminium, it delivers superior weatherproofing, controlled ventilation during wet weather, and crisp architectural sightlines for both new residential builds and structural home renovations.

Why Choose an H1200 x W900 Awning Window?

When you are designing rooms where you want generous natural daylight combined with reliable wet-weather airflow, an H1200 x W900 awning window offers significant functional advantages over standard horizontal sliding window designs. Because the sash is hinged at the top and opens outward from the bottom, the glass pane acts as a protective canopy when opened. This allows you to leave the window partially open for fresh air during rainy weather without rain dripping onto interior sills, bedroom floors, or study desks.

The proportions of 1200mm height by 900mm width make this window an exceptional choice for medium-sized wall openings where a wider 1200mm square frame might feel too crowded. The 1200mm vertical span lets in substantially more natural light than shorter window formats, while the 900mm width fits comfortably between structural framing studs or alongside bathroom vanities and bedroom furniture. When closed, the sash pulls tightly against full-perimeter compression weather seals, delivering an airtight seal that improves thermal performance and blocks outside street noise more effectively than traditional sliding window frames.

Technical Specifications & Features

Built for Australian Climate & Lifestyle

We engineer this H1200 x W900 aluminium awning window to perform reliably across harsh Australian weather conditions and high-moisture indoor environments. Unlike timber window frames that can absorb moisture, swell, warp, or rot when exposed to steamy bathrooms or coastal humidity, our powder-coated aluminium profiles maintain their structural integrity and clean surface finish over decades of daily operation.

The top-hung outward-opening geometry provides outstanding resistance to wind loads and driving rain. Because the sash compresses firmly against continuous rubber perimeter gaskets when wound shut, this window delivers superior acoustic insulation and energy efficiency. Whether your property faces coastal salt air or hot western Sydney summers, the heavy-duty winder mechanism and powder-coated frame ensure trouble-free operation year after year.

How to Configure Your H1200 x W900 Awning Window

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

Glazing selection is particularly important for this versatile window format. If you are installing an H1200 x W900 awning window in a ground-floor bathroom, toilet, or ensuite, upgrading to Satinlite Obscure toughened glass provides complete visual privacy from outside while still flooding the room with natural daylight. For windows positioned in sunny northern or western bedrooms and home offices, selecting Low-E glass or Double Glazing reduces heat transfer and glare significantly. Because awning windows open outward, all insect screens and security screens are fitted internally. This clever layout allows you to operate the chain winder without ever having to remove the screen, keeping your home secure and insect-free.

Frequently Asked Questions

Where is an H1200 x W900 awning window commonly installed? This medium-format size is most popular in bedrooms, home studies, larger bathrooms, ensuites, stairwells, and kitchens. The 1200mm height lets in generous vertical daylight, while the 900mm width fits comfortably into wall spaces where wider 1200mm or 1800mm windows would not fit.

What rough stud opening size do I need for an H1200 x W900 awning window? Your carpenter or builder should prepare a framed opening approximately 20mm taller and 40mm wider than the window frame. For this unit, a rough stud opening of 1220mm height by 940mm width allows adequate room for squaring, plumbing, and packing during installation.

Why choose an awning window over a sliding window for a bedroom or study? An awning window provides a clean, uninterrupted pane of glass when closed and opens outward from the bottom to create a weather-resistant canopy. This allows you to maintain fresh airflow even during rainy weather while offering superior perimeter sealing against draughts and outside street noise.
