Why Does Condensation Form On Windows?
If you've ever woken up to foggy, dripping windows on a cold Melbourne morning, you're not alone. Window condensation is one of the most common complaints among Melbourne homeowners and it can also damage your home if left unchecked.
Condensation forms when warm, humid air inside your home comes into contact with a cold surface and during Melbourne winters, single-glazed windows are almost always the coldest surfaces of your home. The glass temperatures chill, moisture in the air comes into contact with the cold pane and water droplets form on the inside of your windows.
It might seem like a minor inconvenience, but persistent condensation causes real damage over time: rotting timber window frames, peeling paint, mould growth on walls and sills, and poor indoor air quality that can affect the health of your family.
How Double Glazing Reduces Condensation
Warmer Inner Glass Surface
Double glazing helps keep the inside pane of glass warmer, reducing the temperature difference that causes condensation.
Advanced Thermal Insulation
Two panes of glass separated by an insulating argon-filled gap create a barrier that limits heat transfer from outside.
Reduced Window Condensation
By keeping the inner glass closer to room temperature, double glazing prevents moisture in warm indoor air from forming condensation on windows.
Retrofit Double Glazing: A Solution for Melbourne Winters
Winter in Melbourne can pose a challenge for homeowners wanting to minimise window condensation as many Melbourne homes are older Victorian, Edwardian or mid-century properties with original timber windows that are likely to be single-glazed.
At RetroFit Double Glaze, we specialise in upgrading existing timber windows to double glazing without replacing the frames. Our retrofit process replaces only the glass within your current window frames, so you keep the character and craftsmanship of your original windows while significantly minimising condensation, draughts, and heat loss that come with single glazed windows.
Our double glazing solution is particularly effective for heritage and period homes in Melbourne suburbs like Fitzroy, Carlton, Hawthorn, and Kew, where original timber sash windows and casement windows are a defining feature of the home.
Additional Benefits of Double Glazing
Minimising condensation is one of many benefits the double glazing your existing windows can offer. Additional benefits include:
1
Protect your original timber frames
By reducing moisture that causes condensation, double glazing also protects your original timber frames from the rot, swelling, and paint damage that condensation causes over time.
2
Improved indoor air quality
Less condensation means less mould and mildew, contributing to a healthier living environment for your family.
3
Warmer Winters, Cooler Summers
Double glazing reduces heat loss through windows by up to 75%, meaning your home stays at a more comfortable temperature year-round with less reliance on heating and cooling.
4
Lower energy bills
A warmer home requires less heating which can translate to reduced gas and electricity costs.
5
A quieter home
Double glazing reduces external noise by up to 70%, making your home more peaceful among Melbourne's urban and traffic-heavy neighbourhoods.

Frequently Asked Questions
Condensation forms when warm indoor air meets a cold surface. Single-glazed windows are typically the coldest surface in the room, causing moisture to collect on the glass. Double glazing keeps the inner pane at room temperature, eliminating the cold surface that condensation forms on.
Yes. Persistent condensation causes moisture to pool around your frames, leading to timber rot, swelling, paint damage, and mould growth on sills and surrounding walls. Eliminating condensation through double glazing also protects your original timber frames and extends their lifespan.
Yes. Condensation on the inner surface of your window is caused by single glazing and is resolved by double glazing. Condensation between the panes of an existing double glazed unit indicates a failed seal. The unit needs to be replaced and is covered under our 10-year IGU warranty.
Yes. Mould around windows is almost always a direct result of condensation. By reducing moisture at the source, double glazing removes the damp conditions that mould needs to thrive, improving indoor air quality and reducing maintenance.
Most clients notice the difference immediately, particularly after the first cold night. Where windows would previously be dripping with condensation by morning, double glazed windows remain clear. The improvement is most dramatic during Melbourne's winter months.
Yes and it's one of the most effective solutions available for older Melbourne homes. Our retrofit process replaces only the glass within your existing timber or heritage frames, so you get all the condensation and thermal benefits of double glazing without losing the character of your original windows.
Improving ventilation and reducing indoor humidity can help manage condensation, but these measures rarely eliminate it in Melbourne's cold winters. Double glazing addresses the root cause directly by keeping the inner glass surface warm, making it the most effective and permanent solution for condensation on windows.
