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Outdated Appearance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.

Aluminium Window Retrofit in Malvern: What Homeowners Need to Know
Malvern is one of Melbourne's most prestigious inner south east suburbs, known for its Victorian and Edwardian housing stock and its heritage overlay streets. The suburb sits within the City of Stonnington, alongside Toorak and Armadale, and window retrofit is one of the most common renovation decisions homeowners make when upgrading a period home.
Window Society works regularly across Malvern and the surrounding Stonnington corridor. We understand the standard expected on these streets and the specific care that retrofitting a period home's windows requires.
Why Malvern's Period Homes Need Thermally Broken Double Glazing
Malvern's housing stock is dominated by Victorian and Edwardian homes, many built well over a century ago, when thermal performance played no part in window design. Original timber sashes and later single-glazed aluminium replacements are common, and both let heat escape freely in winter and build up quickly in summer.
These homes typically carry high ceilings, generous window openings, and large areas of glazing relative to floor space, which means the thermal penalty of single glazing is felt more acutely than in a smaller modern home. Melbourne's cold winters and increasingly hot summers put real pressure on heating and cooling bills in a house that hasn't had its glazing upgraded.
Thermally broken double glazing changes that equation. U-values between 1.6 and 2.4 W/m²K, compared to around 6.0 for standard single glazing, mean significantly less heat loss in winter and heat gain in summer. For Malvern's larger period homes with substantial glazing areas, the difference in comfort and running costs is considerable.
Retrofitting Slim-Profile Aluminium Into Victorian and Edwardian Homes
Retrofitting a period home is not the same job as fitting windows into a new build. The goal is to upgrade performance while respecting the proportions, sightlines, and character that make the home what it is. Slim-profile thermally broken aluminium is built for exactly this. The narrow frame dimensions sit close to the original sash proportions, so the new windows read as part of the house rather than a visible replacement.
A wide range of powder coat finishes, including off-whites, creams, charcoals, and heritage bronzes, allows the retrofit to match or complement the home's existing colour scheme and trims.
Malvern has a significant concentration of heritage overlay streets, and changes to street-facing facades, including window replacement, may require planning approval through Stonnington Council. This is not a reason to avoid upgrading. It's a reason to work with a supplier who raises it upfront. Window Society advises early on what is likely to need a planning permit and what can proceed without one, and works with heritage architects where council requires their involvement.
Renovations and Extensions on Malvern's Period Homes
Malvern is an active market for high-end renovations and rear extensions to period homes, often pairing a retained heritage facade with a contemporary addition at the back. These projects need a window supplier who can retrofit the front of the home sensitively while supplying larger, more contemporary openings for the new section, all to a consistent standard of finish.
Our SoTherm systems are specified by architects and builders across Stonnington on renovation and extension projects, with shop drawings provided for builder and certifier review and a 9 to 12 week manufacturing lead time that allows for accurate programming within the build schedule.
Window Retrofit Costs in Malvern
Whole-home window replacement for a typical Malvern home ranges from $30,000 to $120,000 for supply and install, reflecting the suburb's larger period homes and the higher specification usually required to retrofit them properly. Heritage overlay projects and homes with extensive glazing will sit above this range.
Every project is custom-quoted based on a free on-site assessment. Window Society assesses your existing windows, discusses any heritage overlay considerations, and gives you 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.
