SECONDARY GLAZING
Secondary glazing offers an ideal solution for those living in listed buildings, conservation areas, or period homes where replacing the original windows or installing standard double glazing may not be permitted.
This system involves fitting a slim, discreet second pane to the inside of your existing window, helping to improve energy efficiency and reduce outside noise without altering the appearance of your original windows.
Secondary glazing can reduce heat loss by up to 60% and is proven to lower external noise by as much as 80%. It also helps to minimise condensation and draughts, all while maintaining the charm and character of your home.
Available in a range of opening styles, it can be tailored to suit your existing sash or casement windows and is fully reversible – making it a preferred option for listed or protected properties.
We offer a range of secondary glazing options to suit both your windows and your budget, and we’ll always provide honest advice to help you decide what’s best for your home.
SECONDARY GLAZING FOR SASH OR CASEMENT WINDOWS
Discreet Glazing That Preserves Character While Improving Comfort
Secondary glazing is a discreet and effective way to improve energy efficiency and noise insulation in period properties without altering the original windows.
By fitting a slim-line internal window behind the existing one, it creates an additional barrier that helps to retain heat and reduce sound—ideal for homes affected by road noise or drafts.
This makes it particularly suitable for listed buildings or those in conservation areas where replacing the primary glazing may not be possible or permitted.
Our high-quality aluminium secondary glazing comes in a variety of styles to suit different window types and can even be beneficial in homes with modern double glazing where noise reduction is a priority.
SECONDARY GLAZING FOR SASH WINDOWS
For traditional sash windows, our most popular secondary glazing option is the tilt-balanced vertical slider. This design allows the secondary panes to mirror the movement of original sashes while offering added functionality – such as inward tilting for easy cleaning and improved airflow control.
It’s ideal for properties with limited access or where preservation of the primary frame is essential. Alternatively, a single pane fixed unit may be used in more restricted areas or where access is not required.
Both options maintain a discreet appearance while delivering excellent thermal and acoustic insulation performance – all while respecting the original character of your sash windows.
SECONDARY GLAZING FOR CASEMENT WINDOWS
For casement-style windows, we offer a range of horizontal sliding secondary glazing units that work perfectly with this traditional window type.
Available in 2 to 5 panel configurations, these units allow for flexible ventilation and easy access while maintaining the classic lines of your original frames.
Our systems include slim aluminium frames, smooth gliding runners, and toughened 4.0mm glass – all tailored to enhance thermal retention, reduce noise intrusion, and minimise visual impact.
Perfect for wide casement windows, bays, or multi-panelled sections, this style provides a discreet and practical solution for improving performance in heritage or conservation area homes.
