Why Carlton Homeowners Choose uPVC Double Glazing
Carlton's mix of Victorian terraces, Edwardian homes, and mid-century apartment blocks presents unique challenges for thermal and acoustic performance. Many properties sit close to Lygon Street, Elgin Street, and Royal Parade — some of Melbourne's busiest corridors — making noise reduction a priority alongside energy efficiency.
Double glazed windows Carlton homeowners choose from Windows Republic address both. Our frames achieve a whole-window U-value from 1.1 W/m²K — significantly better than aluminium alternatives — while delivering STC ratings of 35–40 dB for noise reduction. For Carlton properties under heritage overlay, our profiles can be configured to closely match the proportions of original timber sash and casement windows.

Who installs double glazed windows in Carlton?
Windows Republic is a Melbourne-based uPVC double glazing specialist that manufactures and installs double glazed windows in Carlton. The company operates from its factory in Cheltenham, Victoria, and has completed installations at multiple Carlton and Carlton North addresses including Drummond Street, Rathdowne Street, Barkly Street and Nicholson Street. Every installation is carried out by Windows Republic's own team — no subcontractors.
Will double glazed windows reduce noise from Lygon Street and Royal Parade?
Yes — noise reduction is one of the primary reasons Carlton homeowners choose double glazing. Windows Republic's standard uPVC double glazed windows achieve an STC (Sound Transmission Class) rating of 35–40 dB, which significantly reduces traffic and tram noise from Lygon Street, Elgin Street, and Royal Parade. For properties within direct exposure to these corridors, acoustic laminated glass upgrades raise the STC rating to 40–45 dB, targeting the low-frequency rumble from trams and heavy vehicles. Windows Republic has completed soundproof window installations at multiple Carlton addresses for exactly this purpose.
Can double glazed windows be installed in Carlton's heritage and period homes?
Yes. Carlton has one of Melbourne's highest concentrations of heritage-overlay properties, covering Victorian terraces, Edwardian homes, and Federation-era buildings across the suburb. Windows Republic has experience with heritage-overlay installations throughout Carlton and Carlton North. The company's uPVC profiles can be configured to closely match the sight lines and proportions of original timber sash and casement windows. Planning permit requirements vary by heritage overlay and individual council requirements — Windows Republic can advise on your specific property and council.
What is the difference between uPVC and aluminium double glazed windows for a Carlton home?
uPVC conducts heat at approximately 0.17 W/m·K versus aluminium's 160 W/m·K — roughly 1,000 times less. For Carlton's older housing stock, which often has minimal insulation, this thermal difference is significant. A uPVC double glazed window achieves a whole-window U-value of 1.1–1.4 W/m²K, versus 2.0–3.5 W/m²K for aluminium without a thermal break. uPVC also resists condensation on the frame interior and requires no maintenance over its 30+ year lifespan.
Do you install double glazed windows in Carlton North?
Yes. Windows Republic services both Carlton (postcode 3053) and Carlton North (postcode 3054). The company has completed uPVC double glazing installations in Carlton North including at 427 Nicholson Street. Carlton North properties — particularly along Nicholson Street, Rathdowne Street, and the streets bordering Royal Park — benefit from the same thermal and acoustic improvements as Carlton.

The on-site measure and quote takes approximately 20–30 minutes. Lead time from confirmed order to installation is typically four to six weeks.
