3-Panel Aluminium Sliding Window| H1800 x W2700

The 3-Panel Aluminium Sliding Window with Transom (H1800mm x W2700mm) combines expansive panoramic sightlines with classic architectural character and effortless horizontal gliding operation. Measuring an impressive 1800mm in height by 2700mm in width, this grand-scale three-panel window features an integrated horizontal transom bar that creates a distinct upper highlight section above the smooth-sliding lower sashes—enhancing structural rigidity across the wide 2.7-metre span while adding a timeless architectural aesthetic. Engineered with heavy-duty tandem carriage rollers, interlocking weather mullions, and integrated keyed deadlocking, it delivers exceptional natural ventilation and dependable everyday security. Customise your frame finish from our architectural powder-coated colour palette, select high-performance toughened safety glass or double glazing, and add protective sliding insect or marine-grade stainless steel security screens. Built in Sydney by New Age Construction Group to comply with AS 2047 Australian Standards and delivered securely Australia-wide.

Key Features & Architectural Benefits

• Scale 1800mm x 2700mm Proportions: Standing 1800mm tall and spanning 2.7 metres wide, this grand horizontal window is engineered for feature living room walls, formal dining rooms, master bedrooms, and open-plan entertaining zones where maximum natural daylight and panoramic outdoor viewing are essential.

• Integrated Architectural Transom Bar: Featuring a horizontal structural transom bar across the upper section of the frame, this design separates the window into an elevated highlight pane and a primary lower sliding zone. The transom not only introduces classic visual symmetry and architectural detail but also reinforces the structural integrity of the 2700mm frame against high wind deflection.

• Versatile 3-Panel Configuration: Divided into three generous 900mm-wide bays (available in standard XOX centre-fixed or sliding-to-fixed layouts) to balance unobstructed viewing with flexible airflow. The lower operable sashes slide smoothly along concealed tracks, allowing you to open up to two-thirds of the lower window area for cooling cross-ventilation without protruding into interior or outdoor living spaces.

• Heavy-Duty Tandem Carriage Rollers: Supporting large glazed sashes requires commercial-grade hardware. Each operable panel is fitted with heavy-duty, adjustable tandem carriage rollers that glide effortlessly along nylon-capped aluminium tracks, preventing track wear, jamming, or heavy friction over years of daily use.

• Full-Perimeter Weather & Acoustic Sealing: Engineered with deep interlocking meeting stiles and high-performance EPDM weather gaskets around the frame and transom rebate. When locked shut, the interlocking mullions seal tightly together to block out cold winter draughts, street traffic noise, dust, and heavy driving storm rain.

• Integrated Keyed Security Locking: Fitted with a robust, ergonomic keyed latch mechanism on the meeting stile that locks the sliding panels firmly into the frame, providing reliable home security and peace of mind.

• Maintenance-Free Structural Aluminium: Crafted from thick-gauge, powder-coated structural aluminium joinery designed to support wide 2700mm spans without sagging, bowing, or rotting under intense Australian UV exposure and coastal salt spray.

Glazing & Performance Options

Tailor your grand window's thermal efficiency, visual light transmittance, and privacy level by selecting from our premium safety glass range:

• Clear Toughened Safety Glass: Delivers maximum visible daylight transmittance and crystal-clear exterior viewing at an accessible price point.

• Grey Tint Toughened Glass: Cuts harsh afternoon glare and reduces solar heat gain during hot summer afternoons without darkening your indoor living space.

• Low-E Toughened Glass: Features a permanent, microscopic low-emissivity coating that reflects interior warmth back inside during winter while slowing down radiant summer heat transfer.

• Satinlite Obscure Glass: Textured privacy glass that lets natural daylight stream in while completely obscuring visibility from neighbouring properties.

• Double Glazed Options: Available across clear, tinted, and Low-E variations to create an insulating dead air pocket that slashes thermal heat transfer and significantly cuts outside neighbourhood traffic noise across both the transom highlight and lower sliding sashes.

Integrated Insect & Security Screens

Our 3-panel sliding windows feature dedicated exterior screen tracks that allow protective screens to slide independently across the operable lower glass panels without obstructing interior operation:

• Sliding Flyscreens: Custom-fitted insect screens with durable fibreglass mesh that keep flies and mosquitoes outside while allowing cooling cross-breezes to circulate.

• Diamond Grille Security Screens: Classic aluminium security grilles that provide physical deterrence against intruders alongside everyday insect protection.

• Stainless Steel Security Screens: Heavy-duty, marine-grade woven stainless steel mesh that resists knife cuts, heavy impact, and coastal corrosion, securing your window without obstructing your airflow or outdoor view.
