Why install secondary glazing?

Secondary glazing offers several benefits, especially if you want to improve your windows without replacing them completely.

Common reasons homeowners choose secondary glazing include:

• Improving thermal insulation and reducing heat loss

• Reducing outside noise from traffic or neighbours

• Lowering energy bills

• Preventing draughts around older windows

• Retaining the original windows in period properties

• Improving comfort in older homes

Because the glazing is fitted internally, installation is usually less disruptive than replacing the windows themselves.

What does secondary glazing installation involve?

A professional secondary glazing installer will normally follow several key steps to ensure the system fits correctly and performs as intended.

Step 1: Assessing your windows

Your installer will begin by inspecting the existing windows and measuring the internal frames to ensure the secondary glazing fits precisely.

Step 2: Choosing the glazing system

There are several types of secondary glazing, including sliding panels, hinged units and lift-out panels. The best option depends on how often you open the window and the available space.

Step 3: Custom manufacturing

Secondary glazing units are typically made to measure to match the exact dimensions of your windows.

Step 4: Installation

The secondary glazing frame is fitted inside the existing window reveal and secured carefully to ensure an airtight fit.

Step 5: Sealing and finishing

The installer will check the alignment, seals and operation of the panels before finishing the installation.

Secondary double glazing in listed buildings

Secondary glazing is often recommended for listed buildings and properties in conservation areas, where replacing original windows may not be permitted.

Because the glazing is fitted internally and does not alter the external appearance of the building, it can sometimes be installed without affecting the character of the property.

Many homeowners install secondary glazing in listed buildings to:

• Improve insulation while keeping original sash windows

• Reduce street noise in historic city centres

• Prevent condensation on older single-glazed windows

However, planning rules can vary depending on the building and your local authority. A specialist installer in your area can advise whether permission is required before installation.

How much does secondary glazing cost?

The cost of hiring a secondary glazing installer varies depending on the size of the windows, the glazing system used and how many windows need upgrading.

As a guide, secondary glazing normally costs around £300–£500 per window, depending on the system used.

Costs can vary depending on the glazing design, accessibility and installation complexity. Our secondary glazing cost guide has more detailed pricing information.

What affects the cost of secondary glazing installation?

Several factors can influence the final cost of installing secondary glazing:

• Size and number of windows

• Type of secondary glazing system

• Shape of window openings

• Accessibility of the property

• Whether scaffolding is required

• Thickness of glazing used for sound insulation

• Labour time

When choosing a contractor, always try to compare quotes from several trusted local tradespeople to understand what’s included.

Common mistakes to avoid when installing secondary glazing

• Choosing a system that blocks window access

• Not measuring windows accurately

• Ignoring ventilation needs around older windows

• Hiring an installer without specific experience in secondary glazing
