Premium Fixed Window | H1200 x W900

A fixed window is a stationary architectural picture window designed without operable sashes, mechanical winders, or moving hinges, providing a clean frame profile and maximum daylight transmission. The H1200 x W900 Premium Fixed Window from New Age Construction Group delivers versatile portrait proportions, dependable structural weatherproofing, and superior acoustic sealing for modern Australian residential and commercial builds. Measuring 1200 millimetres high by 900 millimetres wide, this medium-format vertical picture window is engineered specifically for home offices, study nooks, stairwell landings, hallway alcoves, and bathroom feature walls where you want abundant natural light without the need for ventilation.

Versatile Architectural Proportions and Maximum Weatherproofing

Because fixed windows do not require opening sashes or bulky operating hardware, the aluminium frame sits flush around the perimeter of the glass pane. Standing 1.2 metres tall with a 900-millimetre width, this window offers a balanced portrait aspect ratio that suits both traditional and contemporary Australian home designs. This versatile medium format allows builders and architects to introduce structured natural sunlight into rooms where floor-to-ceiling glass is impractical or where wall space is needed below the window frame for furniture and cabinetry.

Beyond its refined visual appeal, the stationary design provides the highest possible level of weatherproofing and energy efficiency. Without operable seams, tracks, or moving seals, the glass panel is fully glazed and sealed directly into our heavy-duty commercial aluminium frame. This creates an airtight and watertight structural barrier that locks out coastal wind, driving rain, airborne dust, and street noise much more effectively than standard operable window formats. When combined with high-performance glazing options, fixed picture windows act as a dependable thermal shield for Australian homes.

Where to Use an H1200 x W900 Fixed Window

The 1200mm by 900mm footprint makes this window an exceptionally versatile solution for bringing natural light into standard residential room layouts. Its most popular application is in home offices and study nooks. Because the 1200-millimetre height leaves generous clearance above standard 750-millimetre office desks and benchtops, you can position workspace furniture directly beneath the window while enjoying a clear, unobstructed outdoor view.

This medium portrait format also excels on stairwell landings, in hallway alcoves, and across master bedroom feature walls. In bathrooms and ensuites, pairing an H1200 x W900 fixed frame with Satinlite Obscure glass creates a bright, private sanctuary without sacrificing wall space needed for vanities or towel rails. Additionally, builders frequently install this stationary window alongside matching 1200x900 awning or louvre windows in a multi-panel combination frame, giving you expansive picture glass next to controllable ventilation.

Configuring Your Custom Window

Every building site has unique solar orientation and thermal requirements, which is why we assemble each fixed window to order based on your exact specifications. Start by selecting your frame colour to match your existing doors, cladding, and architectural profiles across the property.

Next, choose your glass type. Standard Clear glass provides maximum daylight transmission for shaded or south-facing elevations. For north or west-facing walls exposed to intense afternoon sun, choosing Grey Tint helps soften harsh glare. For bathroom installations or side-boundary walls where privacy is critical, Satinlite Obscure glass lets in natural sunlight while blocking external sightlines. If energy efficiency is your primary goal, selecting Low-E glass or Double Glazing will reflect summer heat and retain interior warmth during winter, significantly improving your home's overall WERS thermal rating.

Engineering, AS 2047 Compliance, and Climate Durability

Australian weather conditions can be uncompromising, ranging from coastal salt spray to scorching inland heat. Windows require genuine structural integrity to perform reliably over the lifespan of a home. We manufacture our aluminium frames using thick-walled commercial profiles that comply with AS 2047 structural strength, wind deflection, and water penetration standards.

Every window is assembled, glazed, and inspected by our fabrication team before dispatch. Whether your job site is located in Sydney, Melbourne, Brisbane, or regional Australia, you receive a robust window system ready for straightforward installation into timber, steel, or brick-veneer frames.

Frequently Asked Questions

Where is a 1200x900 fixed window typically installed?

A 1200mm by 1800mm or 1200mm by 900mm fixed window is most commonly installed above desks in home offices, on stairwell landings, in hallway alcoves, or in bathrooms where natural light is desired above vanity height.

Do fixed windows require flyscreens or security screens?

No. Because fixed windows are stationary and do not open, they do not require insect flyscreens or security screens. This allows you to enjoy a completely crystal-clear, unobstructed view through the glass without screen mesh in your sightline.

What is the standard lead time for custom aluminium fixed windows?

Custom aluminium windows from New Age Construction Group are typically manufactured and dispatched within 3 to 5 weeks. Every unit is made to measure and inspected for quality before shipping across Australia.
