Fixed Window | H900 x W1200

The H900 x W1200 aluminium fixed window is a balanced, mid-sized architectural picture window engineered to flood residential rooms with natural daylight while delivering absolute airtight weatherproofing. Measuring 900mm high by 1200mm wide, this horizontal profile is constructed from heavy-duty commercial extruded aluminium. It gives Australian homeowners and builders a rigid, maintenance-free framing solution designed specifically for bedroom highlights, kitchen zones, stairwells, and general living spaces where ventilation is not required.

Key Features & Technical Specifications

• Dimensions: Exactly 900mm in height and 1200mm in width, offering a balanced rectangular proportion that suits standard wall studs, bedroom layouts, and architectural feature openings.

• Frame Profile & Strength: Built from heavy-duty commercial-grade extruded aluminium, engineered specifically to resist twisting, warping, and corrosion across the 1200mm horizontal span.

• Glass Options: Configurable with single or double-glazed safety glass, including Clear, Grey Tint, Low-E thermal performance glass, and Satinlite Obscure for privacy.

• Colour Palette: Choose from hard-wearing architectural powder-coated finishes including Pearl White, Custom Black, or specify a Custom Colour to match your exact exterior cladding, brickwork, or roofing scheme.

• Weather & Energy Performance: Built with continuous perimeter dual-seal weather stripping and structural glazing pockets to prevent air draughts and water penetration, helping your property achieve strong WERS compliance.

• Low Maintenance: Because fixed windows contain no moving parts, mechanical winders, or operating sashes, they offer maximum structural integrity and virtually zero ongoing maintenance.

Ideal Applications for Australian Homes

A 900mm high by 1200mm wide fixed window is one of the most versatile standard dimensions in residential construction. Its balanced proportions fit neatly into standard timber-frame and brick-veneer wall studs, making it a popular choice for bedrooms, studies, and hallways that require maximum natural light and outdoor views. When paired alongside operable awning or casement windows, a fixed 900x1200 picture window acts as a central visual anchor that frames your garden landscape cleanly.

Another major application for this dimension is stairwell and hallway placement. Installing a fixed window in multi-storey stairwells safely illuminates vertical walkways without introducing mechanical moving parts that are difficult to reach or clean. Because fixed windows create an absolute structural seal against the elements, they are also exceptionally popular in coastal regions across New South Wales where wind-driven rain and salty sea air demand robust, maintenance-free weatherproofing.

Configuration Guidance: Customising Your Window

When ordering your H900 x W1200 fixed window online, step through our custom configuration options to suit your room layout and environmental needs:

1. Selecting Your Colour: Pearl White remains a classic choice for traditional brick homes and weatherboard facades, reflecting intense summer heat. Custom Black creates a sharp, contemporary outline that pairs seamlessly with modern render, timber cladding, and matte black hardware. If your renovation requires an exact match to existing window frames, our Custom Colour service ensures a precise result.

2. Choosing Your Glass: Selecting the right glass depends on where the window is installed. For windows facing north or west that catch harsh afternoon sun, Low-E glass or Grey Tint reduces solar heat gain and protects interior furnishings from UV fading. If the window is installed in a bathroom or a bedroom facing a boundary fence, Satinlite Obscure glass lets natural daylight flood the room while keeping outside eyes out.

Australian Standards, Engineering & Quality Guarantee

Every H900 x W1200 fixed window from New Age Construction Group is manufactured to comply with AS 2047, the mandatory Australian Standard for windows and external glazed doors. Framing spans of this size require precise structural engineering to withstand local wind pressures and prevent glass stress. This is why our aluminium frames undergo rigorous testing for structural deflection, air infiltration, and water penetration resistance.

Manufactured at our Smeaton Grange facility in New South Wales, our windows are built using commercial-grade aluminium and quality glazing materials engineered for Australian weather conditions. Whether you are a trade builder requiring reliable site delivery or a homeowner managing a renovation, our windows arrive fully assembled and ready for installation. Standard lead times run between 3 to 5 weeks to accommodate custom powder coating, precision cutting, and quality control prior to Australia-wide dispatch.

Frequently Asked Questions

Where is a 900mm high by 1200mm wide fixed window most commonly used? This balanced dimension is frequently specified for bedrooms, home offices, hallways, and stairwells where you want to maximize natural daylight and frame outdoor views without needing an operable ventilation sash.

Can fixed windows be opened for ventilation? No. Fixed windows are non-operable picture windows designed exclusively to admit natural light and frame outdoor views. If you require ventilation in the same dimension, consider our matching aluminium awning or louvre window options.

What is the standard manufacturing lead time for custom windows? Custom aluminium windows from New Age Construction Group typically require a manufacturing lead time of 3 to 5 weeks. This allows sufficient time for custom powder coating, glass sizing, and thorough quality inspection before shipping anywhere in Australia.
