Fixed Window | H1800 x W1200

The H1800 x W1200 aluminium fixed window is a grand, vertical architectural picture window engineered to flood multi-story rooms and architectural voids with natural daylight while delivering absolute airtight weatherproofing. Measuring 1800mm high by 1200mm wide, this tall, balanced profile is constructed from heavy-duty commercial extruded aluminium with internal structural support. It provides Australian homeowners and builders with a rigid, maintenance-free framing solution designed specifically for grand entryways, stairwells, double-height voids, and expansive feature walls where ventilation is not required.

Key Features & Technical Specifications

• Dimensions: Exactly 1800mm in height and 1200mm in width, offering an impressive vertical rectangular proportion suited for grand architectural spaces, stairwells, and expansive multi-level glazing openings.

• Frame Profile & Strength: Constructed from heavy-duty commercial-grade extruded aluminium, engineered with internal structural support to resist twisting, sagging, and wind deflection across the 1800mm vertical 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 1800mm high by 1200mm wide fixed window is one of the most striking vertical dimensions in modern residential construction. Its grand 1.8-metre stature and generous width make it a preferred choice among architects for double-height voids, sweeping stairwells, and open-plan living areas with high ceilings. Placed where vertical circulation needs illumination, it frames a clean, expansive view of the sky and outdoor landscaping while flooding multi-level interior zones with natural daylight.

Another major application for this dimension is feature wall framing in master suites and contemporary living spaces. Pairing a tall vertical fixed window alongside standard operating windows creates a balanced architectural facade that maximizes solar gain and visual depth. 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 H1800 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 tall stairwell or void 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 bedroom or ensuite facing a boundary fence, Satinlite Obscure glass lets natural daylight flood the room while keeping outside eyes out.

Australian Standards, Engineering & Quality Guarantee

Every H1800 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. Spanning 1800mm vertically requires precise structural engineering to withstand local wind pressures and prevent glass stress across the tall frame. 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 12 to 15 working days to accommodate custom powder coating, precision cutting, and quality control prior to Australia-wide dispatch.

Frequently Asked Questions

Why is an 1800mm high by 1200mm wide fixed window ideal for voids and stairwells? The 1800mm height provides a substantial vertical viewing area that matches multi-story wall heights, while the 1200mm width adds visual weight and openness, illuminating vertical staircases and architectural voids with safe, maintenance-free natural light without requiring operating sashes.

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 12 to 15 working days. This allows sufficient time for custom powder coating, glass sizing, and thorough quality inspection before shipping anywhere in Australia.
