Can’t thank Lachlan enough for coming to us on such short notice, had an accident in the morning and he was out and replaced the window by early afternoon! Helped so much that he was local to Mooroolbark! Couldn’t recommend him enough, for  his advice and professionalism, 10/10

At Challenger Glass and Glazing, we offer retrofit double glazing that gives your home the performance of modern windows, while keeping the look and character of what you’ve already got.

What Is Retrofit Double Glazing?

Retrofit double glazing is a process where a second layer of insulated glass is installed into your existing window frames. The result is a double-glazed unit that improves insulation, reduces noise, and boosts energy efficiency all while preserving your existing timber frames.

It’s a popular choice for:

Older homes with timber windows
People wanting to lower their energy bills
Heritage-listed properties
Homeowners who want better comfort without a full window replacement

Rather than removing the whole window, we remove the old single pane and install a sealed double-glazed unit into the existing frame. This gives you all the benefits of modern double glazing, with far less disruption and cost.

How the Installation Works

Here’s what you can expect when you choose retrofit double glazing:

Measure & Quote

We inspect your existing windows to check they’re suitable for retrofitting, especially timber frames. If they’re in good condition, you’re good to go.

Custom Double-Glazed Units

We order sealed glass units (two panes of glass separated by a spacer) tailored to each opening in your home.

Professional Installation

Our qualified glaziers remove the old glass, prepare the frame, and fit the new double-glazed panels securely into place with care taken to preserve your surrounds.

Clean & Tidy Finish

We seal and finish everything neatly, and leave your home clean, tidy and ready to enjoy right away.

Benefits of Retrofit Double Glazing

Better Temperature Control

Double glazing improves thermal insulation, helping to keep the warm air in during winter and the heat out during summer. That means more comfort, fewer draughts, and a more consistent indoor temperature year-round.

Noise Reduction

Whether it’s traffic, neighbours, or barking dogs, a double-glazed window acts as a sound barrier making your home quieter and more peaceful.

Lower Energy Bills

With less heat escaping in winter and less heat entering in summer, you’ll rely less on heating and cooling — which can reduce your power bills and lighten your carbon footprint.

Keep the Character of Your Home

If you love the look of your original timber windows or live in a heritage home, retrofit glazing lets you keep that charm while upgrading the performance. It’s especially ideal for homes where full window replacement isn’t allowed or just doesn’t suit the style.

Cost-Effective Alternative

Retrofitting is usually more affordable than replacing all your windows. You get the benefits of double glazing without the need to replace entire frames or disturb surrounding finishes.

Is My Home Suitable for Retrofit Glazing?

Most homes with timber-framed windows are great candidates for retrofitting, provided the frames are in good condition.

We’ll inspect your windows as part of the quote to confirm what’s possible and offer a clear recommendation.

What About Full Replacement?

If your existing frames are damaged, rotting, or poorly sealed, we also offer full replacement double glazing. In this case, we replace the entire window (frame and all) with a new double-glazed unit.

We’ll talk through both options during your quote, so you can make the choice that’s right for your home, your goals, and your budget.
