Are Your Windows Costing You More Than You Think?
If your home has single-glazed, timber, or older aluminium windows, you might be dealing with some of these issues.
Cold Drafts & Heat Loss
Old single-pane windows let the cold in and your heating bills up. Double glazing keeps your home at a comfortable temperature year-round.
Street Noise Keeping You Awake
Traffic, neighbours, barking dogs. Double glazed windows reduce outside noise by up to 70%, giving you the peace you deserve.
Rising Energy Bills
Poorly insulated windows are costing you hundreds each year. Our windows pay for themselves through lower heating and cooling costs.
Condensation & Mould
Moisture buildup damages frames and creates health issues. Double glazing eliminates condensation problems at the source.
Outdated Appearance
Old timber or aluminium frames date your home. Modern slim-profile windows add value and street appeal instantly.
Hard to Clean & Maintain
Painted timber needs constant upkeep. Our aluminium frames are virtually maintenance-free and look great for decades.

Solid aluminium with thermal break insulation built through its core to prevent cold travelling through the frame. Strong, zero maintenance, lasts a lifetime.
Verdict - Clear winner, every day of the week. Ticks all the boxes. Thermally Broken Aluminium is universally accepted as the superior window system for high end construction.
Frames so slim they nearly disappear. What architects specify for ultra-luxury modern builds. Can become pricey.
Verdict - Most impressive looking ultra-slim window system in the world. Only if budget allows.
Plastic frames. Insulate well, but Australian sun is hard on plastic. Even if it's "UV Stabilised". Large windows, sliding doors and bi-folds flex with direct sun and heat, requiring adjustment and maintenance way more often than promised.
Verdict - Works well for Passive House types and smaller size Tilt & Turn windows. Not recommended for large sliding doors, bi-folds, floor to ceiling windows and doors.
Semi-decent builder-grade aluminium, but no insulation inside. The cold walks straight through.
Verdict - The builder’s choice to build and sell. Not recommended for homeowners to live with.
Beautiful, insulates very well. Would be rated higher if the maintenance, swelling, staining and sticking wasn't a concern.
Verdict - Only if you'll truly keep up the maintenance.
One thin skin of metal. Zero insulation. Super cheap product. Used by volume builders.
Verdict - Should be illegal.

Window Replacement in Bentleigh: What Local Homeowners Need to Know
Bentleigh sits within the City of Glen Eira and is one of Melbourne's most active renovation and townhouse rebuild markets, built out predominantly with post-war weatherboard and brick homes. Many of these properties still carry their original timber windows, and window replacement is consistently one of the first upgrades homeowners tackle when they renovate or extend.
Window Society works regularly across Bentleigh and the surrounding Glen Eira area. We understand the post-war housing stock the suburb is built on and the specific problems that come with original timber joinery.
Why Bentleigh Homes Need Thermally Broken Double Glazing
Bentleigh's post-war weatherboard and brick homes were typically fitted with single-glazed timber or early aluminium windows, neither of which was specified with insulation in mind. Single glazing has a U-value of around 6.0 W/m²K, meaning heat moves through it almost as freely as through an open window.
In practice that means cold rooms and condensation through winter, and bedrooms and living areas that heat up fast on Melbourne's warmer days. Thermally broken double glazing brings U-values down to between 1.6 and 2.4 W/m²K, a substantial reduction in heat loss and heat gain that homeowners typically notice within the first season.
For a suburb where renovation and rebuild activity is as consistent as Bentleigh's, upgrading the windows alongside other works is one of the more cost-effective ways to lift a home's comfort and performance in one project.
Replacing Original Timber Windows in Bentleigh
A large number of Bentleigh homes still have their original timber windows. Timber is a genuinely good insulator on its own and there's a reason it was the standard for decades, but after 50 to 70 years, most original timber frames in the suburb are showing swollen or sticking sashes, failing putty and seals, and paint that needs constant upkeep to keep the timber protected from Melbourne's weather.
Thermally broken aluminium replaces that ongoing maintenance cycle with a frame that doesn't swell, rot, or need repainting, while matching or improving on timber's thermal performance once paired with double glazing. For homeowners who like the look of the original joinery, slim aluminium profiles and a heritage-appropriate powder coat colour can keep the character of the window while removing the maintenance burden.
We're not going to tell you timber windows are bad. They're not. But once the frame has reached the point of ongoing repair, replacing rather than restoring is usually the more practical and cost-effective path, and it's the conversation we have most often with Bentleigh homeowners.
Renovation and Townhouse Rebuild Projects in Bentleigh
Bentleigh continues to see strong demand for renovations, extensions, and townhouse rebuilds on its post-war blocks. Whether you're renovating an existing weatherboard home or building new dwellings on a subdivided block, a window supplier who can deliver consistently across a full project, and work accurately from architectural drawings, matters for keeping the build on schedule.
Our SoTherm systems are specified on renovation and new build projects across Glen Eira, from single-storey extensions to multi-dwelling rebuilds. Shop drawings are provided for builder review, and our 9 to 12 week manufacturing lead time allows the window package to be programmed accurately against the rest of the build.
Window Replacement Costs in Bentleigh
Whole-home window replacement for a typical Bentleigh home ranges from $25,000 to $80,000 for supply and install. Where a project sits within that range depends on the number and size of openings, the glazing specification, and whether it's a straightforward like-for-like replacement or part of a larger renovation.
Every project is custom-quoted after a free on-site assessment. We look at your existing timber or aluminium windows, talk through what's driving the decision, and give you a straight view of specification and cost before you commit to anything.
