    Soundproof Secondary Glazing for Kensington's Conservation Areas

    Kensington's beautiful Victorian and Georgian properties require sensitive noise reduction solutions. Our secondary glazing noise reduction systems preserve original windows while dramatically reducing traffic noise from Cromwell Road, Kensington High Street, and Exhibition Road.

    The Brompton Conservation Area

    The Brompton Conservation Area, stretching from the Victoria & Albert Museum to Brompton Oratory, contains some of London's finest Italianate stucco-fronted terraces. These Grade II listed properties along Thurloe Square, Egerton Crescent, and Beaufort Gardens face relentless noise from the A4 Cromwell Road—one of London's busiest arterial routes carrying over 40,000 vehicles per day. Our 10.8mm acoustic laminated glass secondary glazing achieves up to 54dB noise reduction, transforming these heritage homes into tranquil sanctuaries while remaining completely invisible from the street.

    The Ladbroke Conservation Area

    North Kensington's Ladbroke Conservation Area encompasses the grand communal gardens and sweeping crescents of the Ladbroke Estate, including Lansdowne Crescent, Stanley Crescent, and Elgin Crescent. Built in the 1840s–1860s, these properties feature original sash windows with delicate glazing bar profiles. Our bespoke secondary glazing is custom-manufactured to match each window's unique proportions, ensuring conservation officer approval. The area's proximity to Notting Hill Gate and the Westway (A40) makes soundproofing a priority for residents seeking peace without compromising the estate's unified architectural character.

    Blocking A4/Cromwell Road Traffic Noise

    Properties fronting the A4 Cromwell Road experience sustained ambient noise levels of 72–78dB from heavy traffic, buses, and emergency vehicle sirens. Our acoustic secondary glazing creates a de-coupled air gap of 150–200mm from the primary window, breaking the sound transmission path. Combined with our 10.8mm laminated acoustic glass—which attenuates across low, mid, and high frequency bands—we consistently deliver 45–54dB reduction for Kensington residents. This brings interior noise levels down to 24–28dB, well below the WHO's recommended nighttime threshold of 30dB for restful sleep.
