Premium Fixed Window | H1800 x W300

A fixed window is a non-operable architectural picture window engineered without hinges, winders, or opening sashes, providing the cleanest possible frame profile and maximum natural daylight transmission. The H1800 x W300 Premium Fixed Window from New Age Construction Group delivers a striking vertical presence, dependable structural weatherproofing, and superior acoustic sealing for residential and commercial Australian builds. Measuring 1800 millimetres high by just 300 millimetres wide, this ultra-narrow vertical slot window is engineered specifically for side-boundary privacy walls, stairwell landings, hallway galleries, and installations above low masonry nib walls where you want to capture generous vertical sunlight without consuming valuable horizontal wall space.

Ultra-Narrow Vertical Sightlines and Maximum Weatherproofing

Because fixed windows do not require opening sashes or bulky mechanical hardware, the aluminium frame sits flush around the perimeter of the glass pane. Standing 1.8 metres tall with a compact 300-millimetre width, this window creates a sleek vertical slit of light that draws the eye upward while leaving room below the frame for low brickwork, timber kickboards, or interior furniture placement. This ultra-slim vertical format allows builders and architects to introduce structured sunlight into extremely tight structural cavities where a wider picture window would interfere with internal framing, columns, or cabinetry layouts.

Beyond its refined visual appeal, the stationary design provides the highest possible level of weatherproofing and energy efficiency. Without operable seams, sliding 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, tall vertical slot windows act as a dependable thermal shield for Australian homes.

Specifications and Features

• Exact Dimensions: 1800mm Height x 300mm Width, proportioned in an ultra-slim 1.8-metre tall vertical slot format engineered for boundary privacy walls and compact framing cavities.

• Heavy-Duty Frame: Built from commercial-grade Australian aluminium engineered to resist twisting, warping, and structural deflection 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 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 high-traffic areas.

• 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 H1800 x W300 Fixed Window

The compact 1800mm by 300mm footprint makes this window an exceptionally versatile solution for bringing natural light into narrow or architecturally challenging building elevations. Its most popular application is along side-boundary walls where strict local council privacy and overlooking regulations restrict large window openings. Installing an 1800-millimetre tall vertical slot window above a low masonry nib wall brings abundant daylight into living rooms, dining areas, or stairwell voids while maintaining compliance and visual privacy from neighbouring properties.

This narrow vertical format also excels in contemporary hallways, stairwell landings, and ensuite bathrooms. Because the 300-millimetre width takes up minimal horizontal space, builders frequently install these windows in repeating rhythmic series along long exterior walls. This colonnade-style layout breaks up large cladding surfaces and introduces structured daylight into the home while leaving ample wall space between each glass panel for artwork, shelving, or structural timber columns.

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 side-boundary walls or bathroom installations 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. Tall glass panels 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

Why choose an 1800x300 fixed window for boundary walls?

An 1800mm by 300mm fixed window is ideal for side-boundary walls because its narrow profile helps meet local council overlooking and privacy regulations while still bringing 1.8 metres of vertical daylight into your living spaces.

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.
