Secondary Glazing
Secondary glazing adds a second layer of glazing inside your existing windows, working alongside your current single or double glazing to keep heat in and noise out. A clear acrylic panel is fitted neatly within the window frame, helping to minimise heat loss through the glass while significantly reducing external noise. It’s a quick, cost-effective solution that suits a wide range of homes. Whether you live in a listed property, a modern flat or a 1930s semi, secondary glazing can make a noticeable difference.

Feature | Secondary Glazing | Double Glazing | Triple Glazing |
|---|---|---|---|
Heat retention | Good improvement vs single glazing; reduces drafts and improves comfort but not as efficient as double/triple. | Strong insulation; a significant step up from both single and secondary glazing. | Highest insulation; noticeably more efficient than double glazing, especially in colder climates. |
Noise reduction | Best performance — large air gap provides superior noise blocking. | Moderate — reduces noise but less effective than secondary glazing. | Moderate to good — better than double in some cases, but still generally less effective than secondary glazing for soundproofing. |
How it's installed | Least disruption — added to the inside of existing windows; no need to remove frames. | Moderate disruption — old units are removed and replaced. | Most disruptive — full window and frame replacement needed. |
Cost | Lower — cost-effective solution; good for improving older windows without full replacement. | Mid-range — more expensive than secondary glazing due to full replacement and materials. | Higher — additional glazing layers and more complex installation make it the most costly option. |
