Secondary Glazing City of London | Square Mile Noise Reduction EC1-EC4
The City of London's residential population has grown rapidly, but the Square Mile was never designed for quiet living. 24-hour construction, HVAC plant noise from neighbouring commercial buildings, early-morning deliveries, and the A40/A1 approach corridors create a challenging acoustic environment. Our secondary glazing serves both the Barbican Estate and the growing number of City-fringe residential conversions.
City Noise Challenges
Construction & HVAC
The City has had near-continuous major construction for two decades. Adjacent commercial buildings run industrial HVAC systems 24/7, generating low-frequency drone that standard glazing cannot attenuate. Our acoustic laminate glass with PVB interlayer specifically targets these sub-250Hz frequencies.
Arterial Traffic & Emergency Services
Fleet Street, Cheapside, and London Wall carry constant traffic. The City's concentration of hospitals, courts, and financial institutions means emergency vehicle sirens are frequent throughout the day and night. Secondary glazing reduces siren peaks from 90dB+ to manageable levels.
Property Types
Barbican Estate
Grade II listed Brutalist apartments with unique window configurations. Bespoke secondary glazing respecting the estate's architectural significance and management requirements.

Office-to-residential conversions under permitted development. Acoustic glazing for large commercial-scale windows in new residential settings.
Case Studies
Barbican Tower, EC2
22nd-floor flat facing active construction site. Combined HVAC + construction noise at 68dB. After acoustic secondary glazing on 6 windows: interior reduced to 24dB — 44dB reduction. Estate management approval obtained.
Result: Home office now viable during daytime construction
