Premium Aluminium Double-Hung Window | H1200 x W800

The Premium Aluminium Double-Hung Window (H1200mm x W800mm) delivers classic vertical proportions, effortless operation, and superior thermal ventilation for modern Australian homes and heritage renovations. Measuring a standard 1200mm in height by 800mm in width, this versatile vertical sliding window features independently operable top and bottom sashes that allow for natural convection cooling—drawing cool outdoor air in through the lower opening while exhausting rising indoor heat through the top. Customise your frame finish from our architectural powder-coated 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

• Classic Standard Proportions: The 1200mm x 800mm dimension is one of Australia's most versatile and widely specified window sizes. It fits seamlessly into bedrooms, studies, kitchens, and bathrooms, making it an ideal choice for both contemporary new builds and traditional timber weatherboard replacements.

• Independently Operable Top & Bottom Sashes: Unlike single-hung designs, both vertical sashes slide smoothly along the frame. This provides flexible airflow control—open the bottom sash for direct ventilation, lower the top sash for child safety and draft-free air circulation, or open both simultaneously for natural whole-room convection cooling.

• Heavy-Duty Concealed Spring Balances: Lifting and lowering the glass sashes is effortless thanks to integrated, heavy-duty spring balances concealed discreetly within the side jambs. The sashes glide without friction and remain firmly suspended at any height without slamming shut.

• Full-Perimeter Weather & Acoustic Sealing: Engineered with continuous compressible 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, ergonomic cam latch on the meeting rail that locks both vertical sashes firmly together, providing reliable everyday home security.

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

Glazing & Performance Options

Tailor your 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 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, making it the preferred option for bathrooms and side-boundary walls.

• 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 neighborhood 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 frame. This allows unobstructed interior operation of both the top and bottom sashes:

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

• 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 window without obstructing your airflow or outdoor view.
