What is Secondary Glazing?
Secondary glazing involves the addition of a discreet secondary window inside your existing primary windows. This method is ideal when replacing original windows may not be an option. It’s an affordable, efficient solution that enhances insulation, reduces energy bills, and minimises external noise.
Types of Secondary Glazing
When choosing secondary glazing, you have several options based on your specific needs and the style of your property:
- Horizontal Sliding Units: Ideal for larger windows, horizontal sliding units allow easy access to the primary window for cleaning and ventilation.
- Vertical Sliding Units: These are commonly used in sash windows, allowing the secondary glazing to slide vertically for ease of use.
- Hinged Units: Best suited for casement windows, hinged units open inwards, offering flexibility and access.
- Fixed Units: If you have windows that don’t require regular access, fixed secondary glazing is a cost-effective option that provides excellent insulation.

How Does Secondary Glazing Improve Energy Efficiency?
Secondary glazing works by trapping a layer of air between the primary window and the secondary unit. This air acts as an insulator, significantly reducing the amount of heat lost through your windows. According to the Energy Saving Trust, installing secondary glazing can save homeowners up to 10% on their heating bills. This solution is particularly beneficial for older homes with single glazing, which are more prone to heat loss.
Secondary Glazing vs Double Glazing
While both secondary and double glazing improve energy efficiency and reduce noise, they differ in terms of installation and cost. Double glazing replaces the existing window unit with a new one containing two panes of glass with an air gap between them. In contrast, secondary glazing is an additional window installed inside the original one. Secondary glazing is generally cheaper than double glazing and is often preferred for listed buildings or properties in conservation areas, where original windows cannot be replaced.

What is secondary glazing?
Secondary glazing is an additional window pane installed on the inside of your existing windows. It enhances insulation, reduces noise, and improves security without replacing the primary windows.
How does secondary glazing help with insulation?
Secondary glazing adds an extra layer that traps air, reducing heat loss. This helps maintain a stable indoor temperature, lowering energy bills and keeping your space warmer in winter.
Is secondary glazing suitable for listed buildings?
Yes, secondary glazing is often recommended for listed buildings, as it doesn’t alter the exterior. It provides the benefits of double glazing while complying with preservation guidelines.
Will secondary glazing reduce noise?
Yes, secondary glazing is an effective way to reduce noise. By adding an additional pane of glass with a gap between it and the original window, secondary glazing creates a sound barrier that can significantly cut down on external noise. This is particularly useful for homes or offices located near busy roads, railways, or noisy urban areas.
The thicker the glass and the wider the gap, the better the noise reduction. For optimal results, a professional installer can recommend the best glass thickness and gap size based on your specific noise concerns.
Can secondary glazing be removed?
Yes, secondary glazing is often designed to be removable, allowing for easy cleaning, maintenance, or removal if no longer required.
What types of windows can have secondary glazing?
Secondary glazing is compatible with most window types, including sash, casement, and bay windows. It’s customised to fit the specific style and size of each window.
Does secondary glazing prevent condensation?
Secondary glazing can help reduce condensation by creating a thermal barrier. However, proper ventilation is also necessary to fully control condensation issues.
Is secondary glazing environmentally friendly?
Yes, secondary glazing is environmentally friendly. It improves energy efficiency by adding an insulating layer to your existing windows, reducing heat loss and minimising the need for heating. This lower energy usage decreases your carbon footprint, helping you reduce greenhouse gas emissions.
How much does secondary glazing cost per window?
The cost of secondary glazing per window in the UK varies based on factors such as window size, type of glazing, and installation method. Here’s a breakdown to help you make an informed decision:
Cost Estimates:
- Standard Window (per square metre):
- £200–£350 for standard sizes
- £350–£500 for larger windows
- £500–£700 for custom sizes or shapes

Is 3mm or 4mm better for secondary glazing?
For secondary glazing, the choice between 3mm and 4mm glass depends on your main priorities: sound insulation, energy efficiency, or cost.
- 3mm Glass: This is often chosen for cost-effectiveness and is suitable for general insulation purposes. It provides a good level of thermal efficiency and basic sound reduction, making it a practical option if your main goal is energy savings without high noise concerns.
- 4mm Glass: This thickness offers enhanced noise reduction and slightly better thermal insulation than 3mm glass. If you live in a noisy area, such as near a busy road, or if you want maximum efficiency, 4mm glass may be worth the slight extra cost.
Does secondary glazing cause damp?
No, secondary glazing itself does not cause damp. It improves insulation and reduces drafts by creating an extra barrier against the cold. However, any form of glazing can contribute to condensation if the room lacks adequate ventilation. Condensation can occur when warm, moist indoor air contacts a cold surface, like a window pane.
With secondary glazing, ensuring good airflow and proper ventilation in your space helps prevent damp or condensation issues. If you’re concerned about damp, consider adding ventilation solutions along with secondary glazing to keep the air circulating.
