Double Glazed Windows Melbourne
Manufactured at our Carrum Downs factory, Novalite double glazed uPVC windows use multi-chambered profiles, argon gas-filled cavities and Low-E glass coatings to deliver industry-leading thermal and acoustic performance. Factory direct — no importers, no middlemen.
What Are Double Glazed Windows?
Double glazed windows consist of two panes of glass separated by a sealed cavity filled with argon gas. Argon is 34% less conductive than air, making it an effective thermal barrier between your home and the outside environment. The result is a window that keeps warmth in during winter and heat out during summer — dramatically reducing your reliance on heating and cooling systems.
Standard single-glazed windows are responsible for up to 40% of a home’s heating energy loss and up to 87% of unwanted heat gain. Upgrading to Novalite double glazed uPVC windows addresses both problems simultaneously: the multi-chambered uPVC frame eliminates thermal bridging through the frame itself, while the Low-E glass coating reflects heat back toward its source on both sides of the glass.
1 pane, no cavity, poor insulation, high energy loss
2 panes, argon cavity, Low-E glass, 20-40% energy savings
Why Melbourne Homeowners Choose Novalite for Double Glazed Windows
Most double glazed window companies in Melbourne are importers or distributors. Novalite is different — we manufacture every window at our Carrum Downs factory.
Melbourne Manufacturing
Every Novalite window is manufactured at our Carrum Downs factory — not imported from overseas. This means custom sizes as standard, faster turnaround, and direct support from the people who made your windows.
Factory Direct Pricing
No importers. No distributors. No showroom markup chain. You deal directly with the manufacturer, which keeps pricing competitive without compromising on materials or quality.
Low-E Coated Glass Included
All Novalite double glazed windows include Low-E coated glass as part of the standard specification. The Low-E coating reduces heat transfer through the glass in both directions — keeping warmth in during winter and heat out during summer.
BAL Bushfire Rating
Novalite is one of very few double glazed window manufacturers in Australia offering BAL-rated products (BAL 12.5, 19 and 29) — an important consideration for properties in designated bushfire zones across Victoria.
Multi-Chamber uPVC Profile
Our 70mm multi-chamber profile with galvanised steel reinforcement outperforms basic uPVC profiles used by lower-cost competitors. More chambers means better thermal break and greater rigidity.
German Hardware
Multi-point locking hardware from Germany engages the frame at multiple points simultaneously. Significantly more secure than single-point locks on standard aluminium windows.
Benefits of Double Glazed Windows in Melbourne
Melbourne’s climate presents a unique challenge: cold, wet winters and hot, dry summers with occasional extreme heat events. Double glazed uPVC windows are engineered to handle this entire range, keeping your home comfortable year-round without the energy cost.
Keeps warmth in during winter (7-star climate zone) and heat out during Melbourne summers. The uPVC frame has near-zero thermal conductivity versus aluminium which conducts heat directly.
Reducing heat transfer through windows can cut household energy bills significantly. The savings depend on your home's existing glazing, but improvement over single-glazed aluminium is always dramatic.
The double glazed cavity significantly attenuates external noise. Ideal for Melbourne homes near arterial roads, trams, trains or the airport flight paths.
Condensation on windows is a sign of heat loss and is a precursor to mould. Double glazed uPVC windows eliminate window condensation by keeping the interior glass surface at room temperature.
German multi-point locking hardware that engages the frame at 3-5 points simultaneously, making forced entry significantly harder than single-point locks.
Double glazed uPVC windows are a highly visible upgrade that appeals strongly to buyers. Energy-rated homes in Melbourne command a measurable premium.
