    W14 Acoustic Specialists

    Barons Court Secondary Glazing — Silence the A4 & the Sky

    W14 faces a rare double noise threat: the relentless rumble of the Talgarth Road flyover and Heathrow's easterly approach overhead. Our acoustic secondary glazing delivers up to 54dB noise reduction — engineered for both low-frequency traffic and high-frequency aircraft frequencies.

    The W14 Double Noise Problem

    Barons Court is unique in London: residents face simultaneous exposure to two distinct noise types that require different acoustic solutions. Standard double glazing addresses neither effectively.

    A4 Flyover — Low Frequency

    Heavy traffic on the elevated A4 generates sustained low-frequency noise (63–250Hz) — the deep rumble that vibrates through walls and standard glass. This requires mass + air gap decoupling.

    Solution: 10.8mm laminated glass + 100–150mm cavity

    Heathrow — High Frequency

    Aircraft on the easterly approach pass at 2,000–3,000ft every 90 seconds, creating high-frequency jet whine (1–4kHz) that cuts through conventional glazing. This requires laminated acoustic interlayers.

    Solution: PVB acoustic interlayer tuned to 1–4kHz band

    W14 Noise Hotspot Map

    Every street in Barons Court has a different noise profile. Here are the key problem zones we've treated:

    Talgarth Road / A4 Flyover

    The elevated A4 carries 40,000+ vehicles daily including heavy freight. The flyover amplifies low-frequency diesel rumble (63–250Hz) that penetrates standard glazing, with sustained levels of 80–88dB at street level along Gledstanes Road.

    Affected postcodes: W14 9DA, W14 9DJ, W14 9DL

    Heathrow Flight Path (Easterly Approach)

    W14 sits directly under the easterly approach to Heathrow Runway 27L. Aircraft pass at 2,000–3,000ft every 90 seconds during peak hours, generating 70–78dB of high-frequency noise that standard double glazing cannot attenuate.

    Affected postcodes: W14 9DB, W14 8RH, W14 8RJ

    North End Road / Lillie Road Junction

    Market traffic, buses (routes 74, 430), and the Earl's Court one-way system create persistent daytime noise affecting the northern W14 boundary.

    Affected postcodes: W14 8ST, W14 8SZ, W14 9NL

    Hammersmith Road Corridor

    The A315 carries continuous traffic between Hammersmith Broadway and Kensington, with noise compounded by bus stops and the District/Piccadilly line surface sections.

    Affected postcodes: W14 8QA, W14 8QH, W14 0QL

    Street-by-Street Solutions

    We've developed bespoke acoustic specifications for Barons Court's most noise-affected streets, calibrated to each location's unique frequency profile.

    Gledstanes Road

    1880s–1890s Victorian terraces

    Window type: 12-over-12 sash with ornamental horns

    Challenge:

    Direct line-of-sight to the A4 flyover — the noisiest residential street in W14. Original sash windows with zero acoustic performance.

    Our Solution:

    10.8mm Stadip Silence with 150mm air gap achieves 50–54dB reduction, transforming 85dB traffic roar into sub-35dB background hum.

    Castletown Road

    Late Victorian mansion flats & terraces

    Window type: 2-over-2 sash with margin lights

    Challenge:

    Combined A4 road noise and Heathrow overflight creates a dual-frequency problem — low rumble plus high-frequency jet whine.

    Our Solution:

    Asymmetric glass specification: 10.8mm laminate for traffic frequencies plus optimized cavity depth for aircraft attenuation.

    Perham Road & Archel Road

    1890s terraced cottages

    Window type: 1-over-1 Victorian sash

    Challenge:

    Quieter than the A4 frontage but still affected by reflected flyover noise and aircraft descent. Narrow window reveals limit options.

    Our Solution:

    Slim-profile 38mm frames with 80mm optimized cavity — maximum noise reduction within tight heritage reveals.

    LBHF Approved

    Compliant with all Hammersmith & Fulham conservation guidelines

    Bespoke CNC Frames

    Laser-measured to fit irregular Victorian reveals within 0.5mm

    65% Heat Savings

    U-value drops from 5.0 to 1.8 W/m²K — draughty terraces transformed

    54dB Reduction

    Tested on Gledstanes Road — A4 roar reduced below library quiet
