Can You Add Double Glazing to Existing Aluminium Windows?

It’s possible to add double glazing to your existing aluminium windows – but the age of your windows, the style of your frames and the age of your property could impact whether a secondary glazing option is best for your home.
Regardless, there are multiple options to insulate your windows, which our aluminium window experts can happily advise you on.
Once installed, your home can begin to benefit from improved insulation, thermal control, increased energy efficiency, reduced condensation and noise insulation.
Read on to discover whether double glazing or secondary glazing is best for your aluminium windows.
What is secondary glazing?
Secondary glazing is the process of adding an additional layer of glazing inside an existing window frame, improving insulation and reducing noise without replacing the original window.
Secondary glazing aluminium frames are designed to uplift the performance of your windows whilst matching their original aesthetic, perfect for older properties or for those who want the benefits of improved energy efficiency whilst keeping traditional stylings.
Secondary glazing is also a more cost-effective option than replacing your windows entirely, as well as being typically easier to approve for listed building consent. This is because secondary glazing can be a reversible change – and in some instances – consent may not be needed at all.
Secondary glazing is available in a range of frame styles, including:
• Horizontal sliding windows
• Vertical sliding windows
• Hinged units
• Lift-out window units
• Fixed unit windows
• Bespoke and arched windows
If you are considering secondary glazing aluminium frames for an older property, always seek permission before any action is taken. The Heritage Window Company is experienced in working within listed building parameters while renovating older properties – as can be seen in our renovation of Evelyn House, Kensington.
Should you add secondary glazing to existing aluminium windows?
Yes, if you have single-glazed aluminium windows, secondary glazing should definitely be added to your property.
Improved insulation and thermal control will save you money on your utility bills, as well as provide better noise insulation and pane durability – acting as an extra deterrent from opportunistic burglars.
If you are looking to fully replace your old windows with new aluminium windows, you should consider double-glazed aluminium windows.
