Premium Fixed Window | H300 x W1800

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 natural light transmission. The H300 x W1800 Premium Fixed Window from New Age Construction Group delivers ultra-slim horizontal sightlines, dependable structural weatherproofing, and superior acoustic sealing for modern Australian residential and commercial projects. Measuring just 300 millimetres high by 1800 millimetres wide, this streamlined architectural ribbon window is engineered specifically for high-level clerestory slots, above-door transoms, shower privacy walls, and custom feature lighting where you want daytime illumination without compromising personal privacy or wall space.

Ultra-Slim Architectural Sightlines 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. In a compact 300-millimetre by 1800-millimetre format, this creates a sleek, uninterrupted slot of light that has become a signature design element in contemporary Australian architecture. This ultra-slim profile allows builders and architects to introduce natural sunlight into tight architectural cavities where a standard opening window would simply not fit.

Beyond its distinctive visual appeal, the stationary design provides the highest possible level of weatherproofing and energy efficiency. Without operable gaps, 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 paired with high-performance glazing, fixed ribbon windows act as a dependable thermal shield for energy-conscious homes.

Specifications and Features
Exact Dimensions: 300mm Height x 1800mm Width, proportioned in a streamlined 1.8-metre wide horizontal slot format engineered for architectural privacy lighting.

Heavy-Duty Frame: Built from commercial-grade Australian aluminium engineered to resist twisting, warping, and structural movement over decades of exposure to harsh weather.

Glass Selection: Choose from standard Clear glass, Grey Tint for solar heat and glare reduction, Low-E thermal glass, Satinlite Obscure for bathroom privacy, or high-performance Double Glazed units.

Powder-Coated Finishes: Available in Pearl White, Custom Black, or Custom Colour finishes applied to resist fading, chalking, and blistering under intense Australian UV radiation.

Zero Maintenance Profile: With no mechanical winders, rollers, or hinges to lubricate or adjust, fixed windows offer a true low-maintenance solution for elevated and hard-to-reach ceiling heights.

Acoustic and Thermal Superiority: Fully sealed perimeter glazing prevents air infiltration, providing outstanding noise reduction and improving internal temperature stability.

Certified Compliance: Tested and manufactured to meet AS 2047 requirements for Australian residential and commercial building compliance.

Where to Use an H300 x W1800 Fixed Window
The compact 300mm by 1800mm footprint makes this window a versatile solution for introducing natural light into privacy-sensitive or spatially constrained rooms. Its most popular application is as a high-level clerestory slot window installed directly below the ceiling line in contemporary living rooms, master bedrooms, and hallways. Placing a slim ribbon window high on the wall allows sunlight to wash across the ceiling while keeping the interior completely private from neighbouring two-storey properties and street traffic.

This slim format also excels in modern bathrooms and ensuites. Mounted high above shower recesses or vanity mirrors, it provides essential daytime illumination without requiring traditional frosted or obscured glass, since the window sits well above eye level. Additionally, builders frequently use the 300x1800 window as an architectural transom light positioned directly above standard 1800-millimetre wide entry doors or internal feature doorways to add extra vertical light to a hallway or foyer.

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. If thermal performance and energy efficiency are your primary goals, Low-E glass or Double Glazing will significantly reduce solar heat gain in summer while retaining interior warmth during winter, 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 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 300x1800 fixed window typically used?
A 300mm by 1800mm fixed window is most commonly used as a high-level clerestory slot window near the ceiling line, as a privacy window above shower recesses in bathrooms, or as a decorative transom window positioned above 1800mm wide doors.

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 12 to 15 working days. Every unit is made to measure and inspected for quality before shipping across Australia.
