TW9 FAQs
How much noise reduction can I expect in TW9?
Homes in Richmond / Kew typically see 35–42 dB reduction on jet approach 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 Richmond / Kew?
For the dominant noise here (Heathrow arrival noise over Richmond), we recommend 10.8mm acoustic laminate + 200mm cavity + edge sealing. 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 Richmond?
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 TW9 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 Richmond / Kew flat is usually £3,200–£6,500 fully installed.
