Choosing the wrong window style for your home is an expensive mistake that shows up every single day in your power bill, your comfort, and eventually your resale outcome. The double hung versus sliding windows decision trips up a lot of Macarthur homeowners, especially on the new estates spreading south from Camden Valley Way and in the established streets closer to Argyle Street in historic Camden.
Both styles are popular across South West Sydney. Both come in powder-coated aluminium. But they perform very differently depending on your room layout, your ventilation goals, and how you actually live in your home. This guide cuts through the noise so you can choose with confidence.

What Is a Double Hung Window and How Does It Work?
A double hung window has two independently movable sashes (the framed glass panels) stacked vertically inside one frame. You can slide the bottom sash up, the top sash down, or both at once. That flexibility is the key feature. Open the top sash on a warm afternoon and hot air escapes near the ceiling while cooler air enters below. This stack-effect ventilation works especially well in the bedrooms of older Camden homes built before ducted air conditioning became standard.
Newage Glass and Aluminium supplies several double hung window ranges to suit different budgets and performance needs, from the entry-friendly Classic Double Hung Windows through to the thermally improved Evoplus Double Hung Windows and the sleek sashless design of the Provista Sashless Double Hung Windows that maximises glass area and gives an almost frameless appearance.

What Is a Sliding Window and Where Does It Shine?
A sliding window opens horizontally, with one or two sashes gliding along a track inside the frame. There are no sashes moving outward, which makes sliding windows a safe, practical choice alongside walkways, above kitchen benches, alfresco areas, or anywhere a projecting sash could be a hazard. They are also easier to clean from inside on upper floors because the sash simply slides across rather than swinging out over a drop.
For wide openings, a sliding window delivers plenty of glass and light without a complicated mechanism. The Classic Sliding Windows and the performance-focused Altitude Sliding Windows both handle the wide spans common in open-plan living rooms across the newer suburbs like Spring Farm and Elderslie.
The honest limitation: a sliding window can only ever open half its total width at a time. If maximum airflow is the goal, a double hung or a casement design will outperform it.

Double Hung versus Sliding Windows: Side-by-Side Comparison
Use this table as a quick reference. No single style wins on every measure; the right answer depends on your specific opening, room, and lifestyle.
| Feature | Double Hung | Sliding |
|---|---|---|
| Opening direction | Vertical (top and bottom) | Horizontal |
| Max ventilation | Up to around 50% of frame area | Up to around 50% of frame area |
| Airflow control | Top, bottom or both | One direction only |
| Best opening shape | Tall and narrow | Wide and low |
| Above walkways/benches | Not ideal (sash projects inward) | Ideal |
| Heritage/classic look | Excellent | Moderate |
| Contemporary look | Good (sashless styles) | Excellent |
| Flyscreen integration | Full-height fixed flyscreen | Half-width sliding flyscreen |
| Double glazing available | Yes | Yes |
| Moving parts | Balances/springs in frame | Rollers on bottom track |
How Does Glass Type Affect Your Decision?
The window style is only part of the picture. Glass choice has at least as much impact on comfort, energy use, and noise as the opening mechanism does. Both double hung and sliding aluminium windows can be fitted with a wide range of glass, and the right combination depends on the room’s orientation, your council’s BASIX requirements, and your budget.
Here is a plain-English breakdown of the main options:
- Single glazing: one pane of glass. Lower upfront cost, but limited thermal and acoustic performance.
- Double glazing: two panes of glass separated by a sealed air gap, which slows heat transfer and dampens outside noise. The double glazed windows range at Newage covers both residential and commercial applications.
- Low-E glass: a microscopically thin metallic coating on the glass surface that reflects radiant heat. Often paired with double glazing for maximum thermal performance. Learn how these two options compare in the Low-E glass versus double glazing article.
- Toughened safety glass: thermally treated to shatter into blunt fragments. Required by the National Construction Code in specific locations such as near doors and low-level openings.
- Laminated glass: two panes bonded with a plastic interlayer that holds the glass together if it breaks. Better for acoustic attenuation. Compare both in the toughened versus laminated glass guide.
- Tinted and obscure glass: reduces glare or provides privacy without sacrificing natural light entirely.
According to the Your Home guide published by the Australian Government, window selection including frame material, glazing type and orientation is one of the most effective passive design strategies for reducing heating and cooling loads in Australian homes. BASIX and NatHERS requirements vary by council and building type; always check with your local council or ask your installer what applies to your project.

What Affects the Cost of Aluminium Windows in NSW?
The price of aluminium windows in NSW varies with size, glass type, glazing layers, powder coat colour, and whether installation involves a straightforward replacement or structural alteration. There is no single reliable figure to quote here; any number you see in a blog post without a site visit is a guess.
The factors that move the price the most are:
- Size and quantity: larger or more numerous windows cost more, but batch orders often improve value per unit.
- Glass specification: double glazing and laminated glass add to the unit cost but are sometimes required by BASIX or the National Construction Code.
- Frame complexity: a standard rectangle costs less to fabricate than an arch or raked frame.
- Powder coat colour: standard colours such as white, black, Dulux Monument and Surfmist are typically priced differently from custom or premium finishes. Browse the full range in the popular powder coat colours guide.
- Installation access: upper-storey windows, heritage openings, or tight sites in older Camden homes may require additional labour.

Should You DIY Window Replacement or Hire a Professional?
Some home improvement jobs reward a confident DIYer. Window replacement in aluminium frames is usually not one of them, and here is why that matters for your hip pocket and your safety.
Custom aluminium windows are made to measure. A frame even a few millimetres out of square will bind, leak, or not meet the weatherproofing requirements of AS2047, the Australian Standard that governs window performance. Getting that measurement right requires the right tools and experience. Beyond fit, there are other considerations.
- Structural openings: widening or raising a window opening involves lintels and load paths. That is a licensed builder’s domain, not a weekend job.
- Building approvals: some window replacements trigger a BASIX obligation or require council notification, particularly on heritage-listed streets in the Camden local government area. NSW Fair Trading sets out licensing requirements for residential building work; review the NSW Fair Trading site for current rules.
- Glazing compliance: toughened safety glass must be installed in the right locations. An unlicensed install that gets this wrong is a liability issue at resale.
- Warranty and insurance: manufacturer warranties on aluminium window systems generally require professional installation to be valid.
For like-for-like replacement in an existing opening of the same size, a very experienced DIYer can sometimes manage, but the risk of a costly mistake is real. For any structural change, double glazing upgrade, BASIX-affected renovation, or heritage property, professional installation is the right call every time. Newage Glass and Aluminium designs, fabricates and installs every window in house at their Smeaton Grange workshop, so the same team that makes your windows fits them, with full licensing and insurance behind every job.

How Does the Professional Installation Process Work?
Knowing what to expect makes the whole project less stressful. Here is how a typical window replacement or new installation works with Newage Glass and Aluminium:

Questions to Ask Any Window Supplier Before You Commit
Not all aluminium window suppliers operate the same way. Asking the right questions upfront saves a lot of frustration later, especially with the cost pressures many Australian homeowners are managing today.
- Do you design, fabricate and install yourselves? Some suppliers outsource fabrication or installation, which can create accountability gaps.
- Are you licensed and insured? Confirm the contractor holds the appropriate NSW builder’s licence for the work scope.
- Are your windows AS2047 compliant? This is the Australian Standard for window performance. Newage windows are AS2047 compliant, which matters for insurance and resale.
- What glass options do you stock or can source? A good supplier will walk you through Low-E, double glazed, toughened and laminated choices without upselling you on things you do not need.
- What lead times are you currently quoting? Honest, specific lead times rather than vague reassurances are a sign of a well-run operation.
- Can you provide references or a project gallery? Completed projects speak louder than any brochure. Browse Newage’s completed work in the project gallery.
When Is a Sliding Window NOT the Right Choice?
Sliding windows get specified in situations where they are simply the wrong tool. Here are the honest cases where you should steer away from them.
If your opening is taller than it is wide, a sliding window will look awkward and will not ventilate well. The sash proportion matters. Similarly, if your primary goal is stack-effect cooling, a design where you can open the top of the window (as a double hung allows) will serve you far better through a South West Sydney summer.
Sliding windows also require a clear, clean track to operate smoothly. In dusty environments near construction zones, or in alfresco areas exposed to leaf litter, the tracks need regular cleaning to prevent sticking. If low maintenance is a priority and the opening suits it, a double hung with good quality balances can actually be easier to live with long-term.
Ready to Choose? Here Is the Honest Bottom Line
For most Camden homes with traditional proportions, heritage streetscape requirements, or bedrooms needing reliable cross ventilation, residential aluminium windows in a double hung configuration are the more versatile and enduring choice. For wide openings in open-plan kitchens, living areas, or anywhere a projecting sash is impractical, a quality sliding window is hard to beat.
You do not have to choose in a vacuum. The right answer for your specific openings, budget, and lifestyle will become clear during a proper site measure, where you can look at real samples, discuss glass options, and get a written quote that reflects your actual job rather than a generic price from a website.

FAQ
How much do double hung or sliding aluminium windows cost in NSW?
The price of aluminium windows in NSW varies with the size of each opening, the glass type chosen (single, double glazed, Low-E, laminated), the powder coat colour, and the complexity of installation. There is no reliable figure to give without a site measure. A free measure and quote at your property is the only way to get an accurate number for your specific job.
Do I need council approval to replace windows in Camden NSW?
In many cases, like-for-like window replacement in the same opening does not require development approval, but this depends on your specific property, whether it has a heritage overlay, and whether the work triggers a BASIX obligation. Requirements vary, so check with Camden Council or ask your licensed installer before ordering. Newage Glass and Aluminium can advise on what typically applies in the areas they service.
Is double glazing worth it for homes in South West Sydney?
Double glazing, which is two panes of glass separated by a sealed air gap, can meaningfully reduce heat transfer and outside noise compared to single glazing. In South West Sydney where summer temperatures regularly exceed 38°C and winter nights can be cold, double glazing is a practical upgrade for bedrooms, living areas and any room facing west. Actual comfort and energy outcomes depend on the overall building design, insulation and how the home is used.
How long does it take to get custom aluminium windows made and installed?
Lead times for custom aluminium windows commonly run a few weeks from measure to installation, depending on the job size, glass specification and current workshop schedules. Newage Glass and Aluminium fabricates in house at their Smeaton Grange workshop, which gives them direct control over quality and timing. Your project manager will give you a realistic timeline when your quote is confirmed.
What glass and powder coat options are available for aluminium windows?
Newage Glass and Aluminium offers a full range of glass types including toughened safety glass, laminated glass, Low-E, double glazed units, tinted and obscure glass. Frames are powder coated in a wide range of colours, from standard whites and blacks through to popular architectural tones like Dulux Monument and Surfmist, as well as custom colour matching. Browse the options in the popular powder coat colours guide on the Newage website.
Do Newage Glass and Aluminium design, make and install windows themselves?
Yes. Newage Glass and Aluminium is a local, family-run specialist that designs, fabricates and installs all aluminium windows and doors in house using their own team at the Smeaton Grange workshop. This means the same people who measure your home make your windows and fit them, with full licensing and insurance across every stage of the job.
