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Outdated Appearance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 Doncaster: What Homeowners Need to Know
Doncaster is one of Melbourne's most established eastern suburbs, part of the City of Manningham, known for its elevated blocks, leafy streets, and city-view aspects that make it one of the most sought-after pockets on this side of town. Window replacement is one of the most common upgrades Doncaster homeowners undertake, whether renovating an existing home or starting from scratch.
Window Society works regularly across Doncaster and the surrounding Manningham area. We understand the suburb's housing stock and the specific challenges its original windows present.
Why Doncaster's Brick Veneer Homes Need Thermally Broken Double Glazing
Doncaster's housing stock is dominated by 1960s and 1970s brick veneer homes, many built on elevated blocks that catch more wind and weather than homes on flatter, more sheltered land. A large share still have their original single-glazed aluminium sliding windows, a standard specification of the era that performs poorly by today's expectations. Thin aluminium frames with no thermal break conduct heat and cold straight through, and single glazing does little to stop it.
The elevated positions that give many Doncaster homes their valued city views also expose them to more direct sun and wind than homes lower down. Original sliding windows in these positions are prone to draughts and rattling, and the temperature difference between exposed north and west-facing rooms and cooler, sheltered rooms can be significant.
Thermally broken double glazing addresses both problems. U-values between 1.6 and 2.4 W/m²K, compared to around 6.0 for standard single glazing, cut heat loss in winter and heat gain in summer substantially. For homes on Doncaster's elevated, exposed blocks, the improvement in comfort is immediately noticeable, not just a number on a spec sheet.
Knockdown Rebuilds and Townhouse Projects in Doncaster
Doncaster has one of Melbourne's most active knockdown-rebuild markets, and the trend shows no sign of slowing. Older brick veneer homes on generous blocks are regularly being demolished and replaced with architecturally designed homes, or subdivided into two or three townhouses, as the suburb's land value and proximity to the city continue to attract investment.
Whether you're building a single new home or a multi-townhouse development, Window Society works from architectural drawings to deliver windows and doors accurately and consistently across the full project. Our new build and extension experience covers everything from single dwellings to multi-unit developments, with shop drawings provided for builder and certifier review and a 9 to 12 week manufacturing lead time that allows for accurate construction programming.
Replacing Original Single-Glazed Aluminium Sliders
If you're not rebuilding, replacing your original single-glazed aluminium sliding windows is one of the highest-impact upgrades available to a Doncaster home. These sliders were the standard specification for most of the suburb's 1960s and 70s brick veneer stock, and decades on they're typically the weakest point in the building envelope: thin frames, single panes, and seals that have long since perished.
A straight swap to thermally broken double glazing, matched to your existing openings, delivers a substantial jump in comfort and efficiency without the scope or cost of a full rebuild. It's a common starting point for homeowners planning to stay in their current home and renovate in stages.
Window Replacement Costs in Doncaster
Whole-home window replacement for a typical Doncaster home ranges from $25,000 to $80,000 for supply and install, depending on the number and size of openings, the specification chosen, and whether the project is a straight replacement or part of a larger renovation or new build.
Every project is custom-quoted based on a free on-site assessment. Window Society assesses your existing windows, discusses what's driving your decision, and provides a straight view of the right specification and cost before you commit to anything. For a full breakdown of what affects double glazing costs across Melbourne, see our double glazing Melbourne guide.
