Carlton is one of inner Melbourne’s grandest Victorian-era suburbs, built around Lygon Street, Carlton Gardens and the University of Melbourne, in the City of Melbourne. Its streets are lined with substantial Victorian terraces, many now student and tenant housing close to the university, and most still run single glazed timber sashes that leak heat in winter and let Lygon Street and arterial noise straight in. Double glazing in Carlton has a clear brief: lift thermal and acoustic comfort in characterful period homes without compromising their proportions, whether the home is owner-occupied or an investment property. APS manufactures German-engineered uPVC double glazed windows and doors that can be sized and styled to suit heritage facades, so an upgrade sits comfortably on a Victorian terrace. For homeowners and investors across Carlton, it is comfort, quiet and efficiency gained while protecting period character.
Carlton’s Victorian terraces call for windows that keep their proportions. Casement and double-hung profiles maintain the narrow vertical lines of the originals while adding a sealed double glazed unit behind them, and because APS makes every frame to measure, a replacement matches an existing period opening rather than forcing a standard size into it.
Casement windows hold the narrow vertical lines of Carlton’s Victorian terraces and seal tightly against Lygon Street noise, while tilt-and-turn windows suit its many upper-floor rentals, where inward-opening sashes make external cleaning safe.
Every frame is built in APS’s own Kilsyth factory. If you are weighing the investment, our Melbourne double glazing cost and pricing guide breaks down what a project like this typically costs.




Carlton has a character all its own among the inner suburbs: alongside its grand owner-occupied terraces, a large share of housing is investment property let to students and staff near the University of Melbourne. That shapes the window decision. For owners, the priority is keeping the period look while gaining comfort; for investors, double glazing lifts tenant comfort, cuts noise and adds long-term value with a frame that does not need repainting. Much of the suburb sits within City of Melbourne heritage overlay, including around Carlton Gardens, so a full external window replacement can require a planning permit.
uPVC double glazing suits both situations. Made to measure, frame widths can be kept slim so the result is sympathetic to a heritage terrace, while a low-e double glazed unit holds warmth inside thin-walled period homes that were never insulated and the sealed frame cuts the Lygon Street and arterial noise. Where a home is under a heritage overlay, we advise raising it at the quote stage and confirming requirements with council. Many of these upgrades qualify for the Victorian Energy Upgrades rebate, and as a registered provider APS handles the VEU rebate paperwork for you.
The cost of Carlton double glazing can vary based on several factors. The size and number of windows or doors you plan to install are primary considerations, with larger or more extensive projects naturally costing more. The type of glazing you choose—such as double or triple glazing—along with any custom features like special coatings or finishes, can also influence the price. Installation complexity is another factor; homes with more challenging access points or unique structural characteristics may require additional labour, affecting the overall cost. While the upfront investment may seem significant, the long-term savings on energy bills and the added value to your home make double glazing a worthwhile investment

Possibly. Much of Carlton sits within City of Melbourne heritage overlay, particularly around Carlton Gardens, and a full external window replacement can require a planning permit. uPVC can be configured to match the sight-lines of original timber sashes, so the result is sympathetic. We advise raising it at the quote stage and confirming requirements with council.
Often, yes. Double glazing lifts tenant comfort, cuts the noise common to Carlton’s busy streets, and adds long-term value with a uPVC frame that does not corrode or need repainting. It can also support a higher-quality tenancy, and many projects qualify for the Victorian Energy Upgrades rebate, which reduces the upfront cost.
Yes. A sealed double glazed uPVC unit blocks considerably more tram and traffic noise than single glazed timber. On Carlton homes near Lygon Street and the arterial roads, matching the right glass thickness to the window style makes a clear difference to how quiet the inside feels.
Considerably. Victorian terraces were built with thin, solid walls and no insulation, so much of their heat escapes through single glazed windows. A low-e double glazed uPVC unit slows that loss sharply, holding warmth inside through winter while keeping rooms cooler in summer.
