2-Panel Aluminum Sliding Window | H900 x W1800

A sliding window is a classic, highly efficient architectural opening system featuring two side-by-side glass sashes where one panel glides smoothly along a horizontal track past the stationary second panel. The Heavy-Duty 2-Panel Aluminum Sliding Window in H900 x W1800 from New Age Construction Group delivers reliable weatherproofing, smooth operation, and effortless cross-ventilation for Australian residential and commercial builds. Measuring 900 millimetres high by 1800 millimetres wide, this balanced 1.8-metre wide dual-sash window is engineered specifically to fit standard 1.8-metre framing bays, making it an ideal specification for kitchens, laundries, bedrooms, and auxiliary rooms where you want dependable half-span airflow and natural light without sashes protruding outward into walkways or outdoor decks.

Balanced 1.8-Metre Utility and Space-Saving Dual-Sash Operation

The primary advantage of a two-panel sliding window is its reliable, space-saving functionality. Because both sashes operate within the same flat plane, the window requires zero external or internal clearance to open. This makes sliders the preferred choice for rooms abutting pathways, verandas, courtyards, or patios where awning or casement sashes might obstruct movement. In this 900-millimetre height format, the low-profile design leaves ample wall space above the sill for cabinetry, task lighting, or splashback tiles, while the 1800-millimetre overall width fits cleanly into standard timber stud spacings and brickwork modules without requiring custom lintels.

Performance and insect management are seamlessly integrated into this model via a matching sliding insect screen track. Unlike fixed screens that can trap debris or hinder cleaning, our sliding screen glides effortlessly on its own dedicated external track. This allows you to position the screen directly over the open sash to keep mosquitoes and flies out while welcoming fresh air inside, or slide it completely out of view when cleaning the glass panes. When closed, high-performance perimeter weather seals and interlocking meeting rails lock tightly against wind-driven rain, acoustic intrusion, and dust.

Where to Use an H900 x W1800 Two-Panel Sliding Window

The 900mm by 1800mm footprint makes this window one of the most versatile specifications for standard residential layouts. Its low 90-centimetre height fits perfectly beneath overhead kitchen cabinets and above standard benchtops, leaving ample clearance for tapware and splashbacks while providing an easy-to-reach sliding sash for quick ventilation during cooking or washing.

This balanced 1.8-metre slider also excels in secondary bedrooms, study rooms, and bathrooms where privacy and natural light are required without sacrificing wall space below the sill. Additionally, the inclusion of a smooth sliding screen ensures you can leave the window open on summer evenings without worrying about insects entering the home.

Configuring Your Custom Window

Every building site has unique solar orientation and ventilation requirements, which is why we assemble each sliding 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 package. Standard Clear toughened glass provides maximum daylight transmission and crisp outdoor viewing for shaded or south-facing elevations. For north or west-facing walls exposed to intense afternoon sun, choosing Grey Tint glass helps soften harsh glare and reduce indoor heat accumulation. For boundary walls or street-facing elevations where privacy is required, Satinlite Obscure glass lets in natural sunlight while blocking external sightlines. If thermal performance is a priority, selecting Low-E glass helps reflect radiant heat and stabilize internal temperatures year-round.

Engineering, AS 2047 Compliance, and Climate Durability

Australian weather conditions can be demanding, ranging from coastal salt spray to driving inland storms. Sliding window systems require robust structural integrity and efficient sill drainage channels to prevent water pooling during heavy downpours. 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.
