Secondary Glazing Islington | Upper Street & N1 Noise Specialists
Islington's elegant Georgian squares sit alongside some of London's busiest corridors: Upper Street, Essex Road, and the A1 City Road. Combined with Northern and Victoria line rumble, and a thriving restaurant and bar scene that peaks past midnight, N1 homes face relentless noise. Our acoustic secondary glazing cuts up to 54dB, letting you enjoy Islington's character without the cacophony.
Islington's Noise Profile
A-Road & Bus Traffic
Upper Street carries 20,000+ vehicles daily including constant bus traffic from five TfL routes. The A1 City Road and Pentonville Road form a noise corridor reaching 76dB at peak hours. Our 10.8mm acoustic glass with 150mm air gap reduces this to under 30dB indoors.
Evening Economy & Tube Vibration
Islington is one of London's top dining destinations — Upper Street alone has 70+ restaurants and bars. Late-night noise regularly hits 80dB. Victoria line vibration adds sub-40Hz frequencies that only acoustic laminate glass can effectively attenuate.

Upper Street can be lively late into the evening; Holloway Road brings a steadier traffic presence, and some streets hear event crowds. In Islington, the most exposed room is often dictated by which elevation faces the source rather than the whole neighbourhood.
Choosing secondary glazing in Islington
For Islington soundproof windows, an internal secondary pane can keep Georgian-square or Victorian terrace sashes in place. We assess air leakage, glass and cavity depth for each N1, N5 or N7 opening and check consent needs for protected buildings.
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.
