What is Secondary Glazing?
Secondary glazing involves adding a second pane of glass on the inside of your existing window , separated by an air gap . Unlike double glazing , which requires a completely new unit , secondary glazing keeps your original windows in place .
This makes it especially popular in:
- Listed buildings where window replacements are restricted .
- Period properties where aesthetics must remain intact .
- Budget-conscious homeowners who want the benefits of noise reduction without full window replacement .

Why Secondary Glazing Works for Noise Reduction
Sound travels in waves , and windows are often the weakest point of a building’s insulation . Secondary glazing reduces noise by:
- Creating an insulating gap between the original window and the new pane .
- Disrupting soundwaves so they lose energy before reaching your ears .
- Adding thickness to the barrier—more glass = more resistance to sound .
When installed professionally , secondary glazing can reduce external noise by up to 80% .
Secondary Glazing Tricks That Actually Work
Here are proven methods that London homeowners use to fight noise pollution:
1 . Maximise the Air Gap
The wider the gap between your existing window and the secondary pane , the better the noise reduction . Aim for at least 100mm if space allows .
2 . Use Acoustic Glass
Standard glass works well , but acoustic laminated glass is designed specifically to block soundwaves . For homes on busy London streets , this is a game-changer .
3 . Seal All Gaps Tightly
Even the smallest gap can let noise through . Professional Glaziers in London use high-quality seals and precise fitting to eliminate leaks .
4 . Consider Secondary Double Glazing Units
For extreme noise (railway lines , airports) , double secondary glazing can be added for an extra layer of insulation .
5 . Combine with Curtains or Blinds
Heavy , lined curtains or acoustic blinds alongside secondary glazing provide a double defense against noise .
Secondary Glazing vs Double Glazing – Which is Better for Noisy Streets?
- Secondary Glazing: Best for listed or period homes , cheaper , and often more effective for noise reduction due to larger air gaps .
- Double Glazing: Better for thermal insulation , modern look , and long-term property value .
