Louvre Window | H1225 x W900

An aluminium louvre window measuring 1225mm high by 900mm wide is a versatile residential architectural window engineered for bedrooms, home studies, larger bathrooms, ensuites, stairwells, and living areas. Standing at 1.225 metres tall by 900mm wide, this H1225 x W900 unit features horizontal tilting glass blades held within a precision-engineered gallery mechanism that opens to provide virtually 100 percent ventilation capacity. Built from heavy-duty Australian aluminium, it delivers outstanding airflow control, low-maintenance operation, and clean architectural sightlines for both new residential builds and structural home renovations.

Why Choose an H1225 x W900 Louvre Window?

When you are designing residential rooms where maximum fresh airflow and generous natural daylight are essential, an H1225 x W900 louvre window offers superior ventilation performance compared to standard sliding or awning window designs. While conventional windows only allow half or partial airflow through their opening area, louvre blades tilt open to horizontal, giving you unrestricted cross-ventilation across the entire frame opening. This makes it an exceptional choice for capturing cooling summer breezes in bedrooms and living areas, or for clearing humidity and odours rapidly in larger bathrooms and laundry rooms.

The proportions of 1225mm height by 900mm width create a balanced opening that fits comfortably into standard structural wall layouts. The 1225mm vertical span lets in substantially more daylight than shorter 665mm louvre units, while the 900mm width provides a broad outdoor view without crowding adjacent interior furniture or plumbing fixtures. When closed, the overlapping blades lock securely into recessed weather channels, providing a reliable barrier against wind, driving rain, and exterior street noise.

Built for Australian Climate & Lifestyle

We engineer this H1225 x W900 aluminium louvre window to perform reliably across coastal, regional, and suburban Australian weather conditions. Unlike timber window frames that can absorb atmospheric moisture, swell, warp, or rot when exposed to steamy bathrooms or coastal humidity, our powder-coated aluminium profiles and UV-resistant gallery components maintain their structural integrity over decades of daily use.

The tilting blade geometry allows you to direct airflow precisely where you need it, directing cooling breezes upward toward the ceiling or downward into the living space depending on the season. Whether your property faces coastal salt air or hot western Sydney summers, the heavy-duty gallery mechanisms and powder-coated frame ensure trouble-free operation year after year.

How to Configure Your H1225 x W900 Louvre Window

You can customise every functional aspect of your louvre 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.

Blade selection is particularly important for this versatile medium-format window. If you are installing an H1225 x W900 louvre window in a ground-floor bathroom, toilet, or ensuite, upgrading to Satinlite Obscure toughened glass blades provides complete visual privacy from outside while still flooding the room with natural daylight. For windows positioned in sunny northern or western bedrooms, selecting Grey Tint or Low-E glass blades reduces heat transfer and glare significantly. You can also add custom insect flyscreens or stainless steel security screens so you can leave your louvres open for continuous airflow with total peace of mind.

Frequently Asked Questions

Where is an H1225 x W900 louvre window commonly installed? This versatile size is most popular in bedrooms, home studies, larger bathrooms, ensuites, stairwells, and kitchen living areas. The 1225mm height lets in generous daylight, while the 900mm width fits comfortably into wall spaces where wider windows would not fit.

What rough stud opening size do I need for an H1225 x W900 louvre 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 1245mm height by 940mm width allows adequate room for squaring, plumbing, and packing during installation.

How do insect screens work with louvre windows? Screens are fitted securely to the exterior side of the window frame so they never interfere with the internal tilt handles or the outward opening arc of the glass blades. This allows you to open and close your louvres freely from inside while keeping insects out.
