What Is Secondary Glazing?
Secondary glazing adds a discreet, independently glazed panel to the inside of your existing window. This creates an insulating layer between the original window and the new glazing, helping to improve thermal performance, reduce draughts and create a more comfortable home.
Secondary Glazing for Listed Buildings & Conservation Areas
If you own a listed building or a property within a conservation area, changing your windows may be subject to additional requirements.
Historic Environment Scotland advises that changes to listed buildings which affect their character can require Listed Building Consent, and specifically recommends considering measures such as secondary glazing when improving the energy efficiency of traditional windows.
Secondary glazing can therefore provide an alternative to replacing original windows, because the existing external window remains in place.
Secondary Glazing vs Double Glazing
Secondary glazing and double glazing work in different ways.
Double glazing replaces the existing single-glazed unit with a sealed unit containing two panes of glass.
Secondary glazing adds a separate pane or glazed panel to the inside of your existing window.
For modern properties, replacement double glazing may be the preferred solution. However, for traditional properties where the original windows need to be retained, secondary glazing can provide a practical alternative.
Is Secondary Glazing Right for Your Home?
Secondary glazing could be a good option if:
✓ Your windows are single glazed
✓ Your home feels cold around the windows
✓ You experience draughts
✓ You live on a busy road
✓ You own a period property
✓ You want to retain your original windows
✓ Your property is listed or in a conservation area
✓ You don’t want to change the external appearance of your home
✓ You’re looking for an alternative to replacement windows
If you’re unsure, our team can assess your existing windows and explain the available options.
Why Choose Secondary Glazing?
Keep Your Original Windows
One of the biggest advantages of secondary glazing is that your existing windows remain intact. Secondary glazing allows you to improve their performance without replacing the external window.
Reduce Heat Loss
Secondary glazing creates an additional insulating layer, helping to reduce heat transfer through the window and making rooms feel warmer and more comfortable.
Improve Acoustic Performance
Secondary glazing can help reduce the amount of outside noise entering your home. The additional glazing layer and cavity between the existing window and secondary glazing can help create a quieter indoor environment.
Preserve Period Character
Secondary glazing is fitted internally, meaning the external appearance of your property can remain largely unchanged.
Frequently Asked Questions:
Is secondary glazing better than double glazing?
Neither is universally better. They are different solutions for different properties. Secondary glazing can be particularly useful where existing windows need to be retained, such as traditional or heritage properties.
Can secondary glazing be fitted to sash and case windows?
Yes. Secondary glazing can be used alongside traditional sash and case windows and is particularly useful where homeowners want to retain the original windows.
Can secondary glazing be used in listed buildings?
It can be an option for listed and historic properties because it allows the original windows to remain in place. However, requirements vary by property, so owners should check whether consent is required before carrying out work.
Will secondary glazing change the appearance of my property?
Secondary glazing is installed internally, so it can have significantly less impact on the external appearance of a property than replacement windows.
