N6 FAQs
How much noise reduction can I expect in N6?
Homes in Highgate typically see 38–45 dB reduction on low-frequency road noise, depending on window size, façade condition and glass specification. We measure before and after with a calibrated sound-level meter as part of every install.
What glass specification is best for Highgate?
For the dominant noise here (Archway Road & North Circular traffic), we recommend 10.8mm acoustic laminated glass with 150mm cavity. In listed buildings or conservation areas we use the same acoustic performance in a discreet slimline frame that satisfies planners.
Do I need planning permission in Haringey / Camden?
Secondary glazing is internal work and is almost never controlled by planning permission — even in conservation areas. Grade II listed buildings need Listed Building Consent, which we handle with drawings and a heritage statement as part of the quote.
How much does a typical N6 install cost?
London prices in 2026 start at £450 per window for a small sash and rise to £1,600 for large Georgian sashes with premium acoustic glass. A three-bed Highgate flat is usually £3,200–£6,500 fully installed.
