Secondary Glazing Hammersmith | Flyover & A4 Traffic Noise Specialists
The Hammersmith Flyover is one of London's most notorious noise sources, carrying the A4 at elevation directly through the heart of W6. Combined with the busy King Street, Hammersmith Broadway interchange, and Piccadilly/District line surface sections, residents face relentless multi-directional noise. Our acoustic secondary glazing is purpose-engineered for flyover-adjacent properties.
Hammersmith Noise Profile
The Flyover & A4
The Hammersmith Flyover carries 80,000+ vehicles daily at roof level, creating a unique noise challenge: sound radiates downward and sideways, making conventional ground-level barriers ineffective. Properties within 200m experience 72-80dB. Our secondary glazing with 10.8mm acoustic laminate and wide air gaps is the only practical residential solution.
Tube & Bus Interchange
Hammersmith is served by four tube lines and 20+ bus routes. The Broadway interchange generates constant noise from idling buses, traffic lights, and pedestrian activity. Surface sections of the District and Piccadilly lines add rail noise to properties along Hammersmith Grove and Shepherd's Bush Road.
