Frequently Asked Questions About Secondary Glazing in London
Noise and soundproofing in London
A London home can face very different sounds depending on the room: road traffic at the front, trains at the rear or late-night activity below a bedroom. The first step is to identify which windows face the source and when the disturbance is worst, rather than assume one specification fits every address.
Choosing secondary glazing in London
For soundproofing windows in London, a well-sealed secondary pane creates a separate barrier inside the original window. Glass choice, cavity depth and ventilation need to be considered together; we survey each opening before suggesting acoustic secondary glazing for a period home, flat or workplace.
Results depend on the existing window, surrounding structure and installation. Noise sources above describe local context, not measured levels at your address.
Internal noise level calculator
Estimate the level you are likely to measure inside the room. Set the level outside the window, then describe the window size, the glazing specification, the wall construction and how well the window seals.
Quiet side street 55dB, busy London road 70-78dB, main arterial or rail 80dB+.
Estimated internal level
43 dB
Estimated reduction
27 dB
Intrusive indoors; a higher specification is advisable
Window size: The most common London sash or casement size.
Glazing: Original 3-4mm glass with worn seals; around 25dB in good condition.
Wall construction: Heavy masonry performs well, so the window is the weak point.
Sealing: Small perimeter gaps let higher frequencies leak through.
Estimates are indicative and based on typical performance recorded during our London installations. Reduction of up to 54dB is achievable in suitable configurations; actual performance depends on the existing window, glass specification, air-gap depth, installation quality, room construction and noise frequency. Only an on-site survey with a calibrated meter can confirm figures for your property.
