- 🏠 Warmer in winter
- ☀️ Cooler in summer
- 🔇 Less outside noise
- 💧 Reduced condensation
- 💰 Lower heating and cooling costs
- 🌿 Better energy efficiency
Why Double Glazing?
A significant amount of heat can be gained or lost through your windows.
Double glazing uses two panes of glass separated by an insulated spacer, creating a thermal barrier that helps reduce heat transfer through the window.
The result is a home that feels more comfortable throughout the year, with less reliance on heating and cooling.
- ❄️ Keep the warmth inside during winter
- ☀️ Reduce unwanted heat entering during summer
- 🌡️ Maintain a more consistent indoor temperature
- ⚡ Improve the overall energy efficiency of your home
Why Retrofit Your Existing Timber Windows?
Replacing quality timber windows isn’t always necessary.
Our retrofit system allows us to install new double glazed units directly into many existing timber window frames, helping you retain the original style and character of your home while significantly improving performance.
Unlike secondary glazing or an add-on panel, our retrofit double glazing is installed directly into the existing window system for a clean, permanent finish.
Our experienced team carefully modifies each window to accommodate the new double glazed unit, with attention paid to seals, operation, appearance and the finer finishing details.

A few useful answers
Before we
get started.
Can every timber window be retrofitted?
We need to check the timber condition, frame and sash dimensions, and how the window operates. Photos are a useful starting point, followed by a site assessment.
Do I need to replace all my windows at once?
We can quote the windows you want to prioritise. Let us know which rooms you’re looking to improve and we’ll discuss a suitable scope.
What should I send for a quote?
Send photos of the windows, approximate sizes and your suburb. We’ll let you know what else is needed before confirming the work.
