Retrofitting allows you to enjoy the benefits of modern double glazing without needing a complete overhaul. Whether it’s upgrading to improve insulation or replacing damaged units, we deliver solutions tailored to your needs, helping you create a home that feels just right.
What Is Double Glazing?

Double glazing is commonly used in windows and doors and is made up of two single panes of glass separated by a spacer. The space between the glass is typically filled with air or an inert gas like argon.
Double glazing is an insulated glass unit (IGU) assembled and sealed in a controlled factory environment.
This creates a thermal insulation barrier that reduces heat transfer and helps regulate the temperature inside the building.
The use of double glazing can improve the energy efficiency of a building, reducing heating and cooling costs and making the interior more comfortable.
In addition to its insulation properties, double glazing can also reduce noise from outside and improve the overall security of the building.
What Is Retrofit Double Glazing?
Retrofitting is an innovative way to upgrade single glazing to new double glazing. This process preserves the original look of your home or office while improving insulation and reducing external noise.
Choosing to retrofit helps you save on your renovation budget. Instead of completely replacing your window or door which can be expensive, we replace your existing single glazed glass with a new factory sealed energy efficient double glazed unit, making retrofit a more affordable choice.
Our process involves making minor adjustments to the frame, such as a new aluminium or timber bead, to account for the new double glazed unit. The aesthetics look virtually the same allowing you to retain the character of your home.
Our double glazed units are made to Australian Standards and factory sealed right here in Melbourne, then installed at your site. We do not use your existing glass. The process is relatively quick and hassle-free, leaving you to enjoy the comforts of your new double glazing.
Key advantages of Retrofit Double Glazing:
- Warmer, dryer, more comfortable living space.
- Improved thermal efficiency for year-round comfort.
- Preservation of natural light levels and glare reduction.
- Fading reduction.
- Noise reduction for quieter interiors.
- Seamless compatibility with timber and aluminium frames.
- Cost savings on renovation expenses (upgrade vs. full replacement of frames and glass).
Retrofitting is ideal for maintaining the charm of any home or adding value without extensive remodelling.
Why Replacement Glazing Is Sometimes Necessary?

Why Replacement Glazing Is Sometimes Necessary?
Damaged or outdated double glazed units can compromise your home’s comfort and energy efficiency. Replacing old glazing ensures optimal insulation, clearer views, and a fresh look.
Replacement is when we replace your standard double glazing with new high performing double glazing. The process is quick, simple and cost effective as we only replace the double glazing units themselves.
Why would you replace your existing double glazing window or door?
As technology changes and the need for better thermal insulation and/or solar control becomes more important for your home or office, replacement allows you to change the performance characteristics (e.g. energy efficiency, solar control) of your windows and doors.

This service is particularly beneficial for addressing:
- Condensation between glass panes
- Cracks or damage to existing glazing
- Improving noise control
- Frames that need modernised solutions
- Improving insulation
- Upgrading to a more energy efficient product with higher ratings
Our replacement solutions provide a seamless upgrade, restoring the functionality and appearance of your windows and doors.
