Double Glazing

Secondary Glazing vs Traditional Double Glazing

If you’re looking to install double glazing windows to reduce heat loss or to reduce noise, it’s easy to become bogged down in technical details that make it difficult to decide on one solution over another. With traditional and add-on options available, it’s important to decide which one is right for you and your specific requirements. Here’s a quick look at how secondary and traditional double glazed windows compare.

Insulation Benefits

Secondary glazing from Stop Heat Loss is just as effective as traditional double glazed windows in providing thermal insulation to your home. Heat loss and gain from your windows will be reduced by up to 50%, leading to significant savings on energy bills.

Effectiveness at Reducing Noise Levels

Traditional double glazing typically results in a 20% reduction in noise. This is achieved through the installation of two panes of glass, separated by a space of approximately 5 to 20mm. Further noise reductions can be gained by increasing this distance. The add-on double glazing system by Stop Heat Loss employs spaces of up to 100mm, creating a larger space of air between the panes that cushions sound and results in a more effective reduction in noise. As a result, noise can be minimised by up to 70% – more than double the efficiency of traditional methods.


When taking cost into consideration, the secondary glazing system from Stop Heat Loss is a clear winner, providing a fantastically affordable solution to traditional solutions. Double glazing requires the complete removal and replacement of existing windows – an unnecessary expense that often blows out the cost to over $1000 per square metre installed. Fortunately, Stop Heat Loss can work with your current windows to lower costs. Utilising existing windows to keep costs to a minimum, our secondary double glazed windows cost less than half the price of complete replacements, making it a cost-effective solution that saves money as well as time.

Ease of Installation

Traditional double glazing requires a full replacement of existing windows, turning the installation into a lengthy ordeal. However, Stop Heat Loss can install add-on double glazing on existing windows, simplifying the process from beginning to end.
