RBKC Heritage Specialists
The Royal Borough of Kensington and Chelsea is one of London's most protected — and most acoustically exposed — postcodes. Stucco terraces on Cromwell Road, Earl's Court Road and the A4 face constant 24-hour arterial traffic, while western streets sit directly under the Heathrow 09L/27R approach.
Our secondary glazing installers deliver up to 54dB reduction using 10.8mm Stadip Silence acoustic laminate, fully reversible and routinely approved by RBKC conservation across South Kensington, Chelsea, Knightsbridge, Holland Park and Notting Hill.
RBKC properties face a double acoustic load: A4/A315 arterial traffic at 76–82dB facade levels, and jet approach noise from the Heathrow 09L/27R flight path — typically 65–75dB overhead every 90 seconds during easterly operations.
Replacement windows are effectively off the table across most of the borough: RBKC operates one of the UK's strictest listed and conservation regimes. Internal secondary glazing is the only route that satisfies heritage constraints and materially reduces both traffic and aircraft noise.
One of London's busiest 24-hour arterials. 10.8mm laminate is engineered for the low-frequency HGV and coach spectrum single glass transmits unattenuated.
Western RBKC streets sit under the 09L/27R approach. Wide 100–150mm air gaps decouple the acoustic bridge that carries jet rumble indoors.
Grade I and Grade II installs across the Royal Borough. Heritage statement, drawings and reversibility note included with every RBKC proposal.
In-house teams only, no subcontractors, 10-year performance guarantee on frames, seals and acoustic outcome.

Kensington Reviews
"Cromwell Road is a wall of sound from 6am onwards. RBKC listed-building consent came through with the heritage statement they prepared. We now shut the front reception door and hear absolutely nothing."

Stucco terrace, Cornwall Gardens
"Heathrow easterly ops used to have jets overhead every 90 seconds. The wide air gap they specified made the difference — low-frequency rumble is gone, not just muffled."

"Sirens from Chelsea & Westminster Hospital were the trigger for us. Installation was tidy, quiet, and finished in a single day. The acoustic outcome is the best money we've spent on the flat."
