Aluminium Double Hung Windows Australia | Custom Sizes & Colours

Why Choose Aluminium Double Hung Windows for Australian Homes

Traditional timber sash windows are a common sight in classic Australian homes, but they come with serious structural headaches. Old timber sashes absorb seasonal moisture and swell shut during wet summers, while their internal counterweight cords inevitably snap and jam inside the wall cavity. Custom aluminium double hung windows solve these problems by replacing heavy timber and clumsy lead weights with rigid, powder-coated aluminium profiles and concealed stainless steel spring balances. You get the classic vertical proportions of a heritage window without the endless sanding, painting, and maintenance.

Ventilation efficiency is where double hung windows outperform standard residential joinery. By lowering the top sash by a few inches and raising the bottom sash at the same time, you create an active thermal exchange. Hot, stale air trapped near your ceiling is drawn outside through the upper gap, pulling cool garden breezes in through the lower gap. This convection cooling effect lowers indoor temperatures quickly on warm summer evenings without needing to run air conditioning.

Because both sashes operate vertically inside the window track, double hung frames never swing outwards over garden paths, decking, or narrow side alleys. You can install them alongside high-traffic outdoor living areas or close to boundary fences without risking anyone walking into an open window pane. The interlocking meeting rails and compressible weather seals lock out draughts, dust, and driving storm rain when closed.

Key Features & Custom Configuration Options

Every renovation, Hamptons build, or commercial upgrade has distinct styling and thermal targets. We manufacture our aluminium double hung windows to order, allowing you to configure the frame finish, performance glazing, and security screening to match your exact building schedule.

Architectural Colour Palette

• Pearl White: A crisp, classic gloss finish that reflects summer radiant heat and complements traditional Hamptons weatherboards or coastal brick facades.

• Custom Black: A clean, bold matte black finish that adds modern architectural contrast and highlights surrounding garden views.

• Custom Colour: Need to match a specific facade colour? We can supply custom powder-coated shades so your new vertical windows match your existing exterior colour scheme.

Performance Glass & Glazing

• Clear Glass: Standard float or toughened safety glass that provides maximum visible daylight and clean exterior viewing at an affordable price point.

• Grey Tint: Tinted glass that cuts harsh glare and reduces solar heat gain during hot afternoon sun without darkening your interior living spaces.

• Low-E Glass: Coated with a microscopic low-emissivity layer that reflects indoor warmth back inside during winter while slowing down radiant summer heat.

• Satinlite Obscure: Textured privacy glass that is ideal for ground-floor bathrooms, laundries, and ensuites where you want fresh vertical airflow without compromising privacy.

• Double Glazed Options: Available across clear, tinted, and Low-E variations. Double glazing traps an insulating air pocket between two glass panes, significantly reducing thermal heat transfer and cutting traffic noise.

Integrated Insect & Security Screens

• No Screens: A minimal visual finish suited for internal breezeways, upper-storey windows, or enclosed patio spaces where insect control is not required.

• Flyscreens: Standard external insect screening that covers the entire frame height, allowing you to open both top and bottom sashes while keeping mosquitoes and flies outside.

• Diamond Grille: Traditional heavy-duty aluminium security grille screens that provide a visual deterrent and physical protection for ground-floor bedrooms and front facades.

• Stainless Steel Security Screen: Premium marine-grade stainless steel woven mesh that resists knife cuts, heavy impact, and coastal corrosion. The screen frame mounts cleanly to the exterior of the window, allowing full operation of both vertical sashes from inside the home.

Custom Sizing & Made-to-Measure Engineering

Buying standard off-the-shelf windows from large hardware retailers often forces you to pack out timber framing or compromise on your window placement. We manufacture every aluminium double hung window to your exact height and width measurements down to the millimetre. This precision sizing ensures your window drops straight into your prepared structural opening, saving your carpenter time and money on site.

Our range scales from compact 800mm-high bathroom windows up to tall 2100mm statement windows for classic living rooms and bedrooms. Every sash is engineered with integrated finger grips along the top and bottom rails for easy lifting and lowering. Instead of bulky pulley systems, our frames use heavy-duty, tension-adjustable spring balances that support the sash weight evenly, allowing smooth vertical movement that will not drop or slide shut unexpectedly.

Where to Use Double Hung Windows Around Your Property

Aluminium double hung windows are versatile enough to work across a wide variety of residential rooms and commercial fit-outs:

• Hamptons & Heritage Renovations: Recreate the timeless vertical grid look of traditional timber sash windows while upgrading your home with modern double glazing and powder-coated durability.

• Narrow Pathways & Verandahs: Provide maximum bedroom and living room ventilation along side boundaries or covered deck areas where outward-pushing windows would block foot traffic.

• Kitchens & Laundries: Enjoy easy single-handed vertical opening over sinks and benchtops where sliding window tracks might be harder to reach.

• Multi-Storey Bedrooms: Lower only the top sash during the night to let fresh air circulate safely while keeping the bottom opening closed for child safety.

Australian Standards, WERS Ratings & Built-to-Last Durability

Quality building products need to prove their structural performance under rigorous testing. All our custom aluminium double hung windows are built to comply with AS 2047, which is the official Australian Standard for windows and external glazed doors. This certification guarantees that your joinery has been tested for structural deflection, operating force, air infiltration, and resistance to water penetration during severe storm conditions.

We also design our window joinery to support WERS (Window Energy Rating Scheme) efficiency goals. Pairing our thermally solid aluminium profiles with Low-E glass or sealed double glazing helps your home meet modern 7-star energy rating requirements while lowering your heating and cooling bills. All powder-coated finishes are applied under strict quality controls for surface adhesion and film thickness, ensuring the metal resists chalking, fading, and peeling under harsh Australian sun.

Frequently Asked Questions

How much do aluminium double hung windows cost in Australia?

Prices depend on overall window height, width, glazing selection, and screen upgrades. A standard custom-sized residential double hung window with clear glass generally costs between $450 and $950, while large double-glazed windows or systems fitted with stainless steel security mesh can range from $1,000 to $2,100+. Using our online product configurator lets you check live pricing for your exact dimensions instantly.

What is the difference between single hung and double hung windows?

In a single hung window, only the bottom sash slides upward while the top pane remains fixed in place. In a double hung window, both the top and bottom sashes move independently. Double hung windows offer superior ventilation because you can open both sashes at once to create convection cooling, or lower only the top sash for secure, draught-free night airflow.

Are aluminium double hung windows hard to lift and open?

No. Unlike old timber windows that relied on heavy cast-iron counterweights and cotton cords, our aluminium double hung windows use internal pre-tensioned stainless steel spring balances. These springs carry the weight of the glass, allowing you to raise and lower the sashes smoothly with very little effort.

Can you put flyscreens or security screens on a double hung window?

Yes. Every aluminium double hung window we supply can be fitted with an external flyscreen, diamond grille screen, or woven stainless steel security screen. Because the screen frame sits on the exterior perimeter of the window track, you can freely operate both the top and bottom sashes from inside your home without removing or disturbing the screen.
