Premium Aluminium Double-Hung Window | H1800 x W800

The Premium Aluminium Double-Hung Window (H1800mm x W800mm) combines classic vertical proportions with modern thermal performance, making it the ideal choice for narrow architectural openings, heritage renovations, and feature bedrooms. Standing at an impressive 1800mm in height by 800mm in width, this extra-tall vertical window features two independently operable sashes that slide up and down to create superior convection airflow—drawing cool outdoor air in through the bottom while releasing trapped ceiling heat through the top. Customise your frame finish from our architectural colour palette, select high-performance safety glass or double glazing, and add protective exterior insect or marine-grade stainless steel security screens. Built in Smeaton Grange by New Age Construction Group to comply with AS 2047 Australian Standards and delivered securely Australia-wide.

Key Features & Architectural Benefits

• Extra-Tall Convection Ventilation: At 1800mm tall, this vertical window excels at whole-room natural cooling. By opening both the top and bottom sashes simultaneously, warm indoor air near the ceiling naturally exhausts through the top opening while fresh, cool outdoor air enters through the lower aperture.

• Independently Operable Top & Bottom Sashes: Unlike single-hung alternatives, both sashes slide vertically along the frame. This allows flexible ventilation control—keep the bottom sash closed for child safety or ground-level privacy while lowering the top sash to let fresh air circulate.

• Heavy-Duty Concealed Balance Springs: Lifting extra-tall 1800mm glass sashes is made effortless by integrated, heavy-duty spring balances concealed inside the jambs. The sashes glide smoothly and remain firmly suspended at any height without slamming shut.

• Full-Perimeter Weather & Acoustic Sealing: Engineered with continuous weather gaskets and an interlocking central meeting rail. When latched shut, the sashes compress tightly to lock out cold winter draughts, street noise, dust, and heavy driving storm rain.

• Secure Central Cam-Catch Locking: Fitted with a robust cam latch on the meeting rail that locks both vertical sashes firmly together, providing reliable everyday home security.

• Maintenance-Free Structural Aluminium: Built from thick-gauge structural aluminium joinery that will never absorb moisture, ensuring the tall frame will never warp, swell, or rot under intense Australian sun and coastal salt spray.

Glazing & Performance Options

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

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

• Grey Tint Glass: Cuts harsh afternoon glare and reduces solar heat gain during hot summer afternoons without darkening your indoor 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, making it the preferred option for side-boundary walls and bathrooms.

• Double Glazed Options: Available across clear, tinted, and Low-E variations to create an insulating air pocket that slashes thermal heat transfer and significantly cuts outside street traffic noise.

Integrated Insect & Security Screens

Because double-hung sashes slide vertically within the internal frame tracks, protective screens mount cleanly to the exterior face of the window, allowing unobstructed interior operation of both sashes:

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

• Diamond Grille 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 extra-tall ground-floor openings without obstructing your airflow or outdoor view.
