EC1 Acoustic Specialists
Clerkenwell Secondary Glazing & Loft Conversion Noise Solutions
Clerkenwell's converted Georgian warehouses, Victorian workshops, and Edwardian terraces are some of London's most desirable addresses — but EC1's dense urban fabric means persistent noise from Farringdon Road traffic, the Thameslink corridor, and Exmouth Market nightlife. Our acoustic secondary glazing delivers up to 54dB reduction.
Farringdon Road Traffic
The A201 carries heavy HGV and bus traffic at 72–80dB. Our 10.8mm acoustic laminate blocks the low-frequency rumble that resonates through warehouse conversions' open-plan spaces.
Exmouth Market Nightlife
Restaurants, bars, and late-night venues create persistent evening noise at 65–75dB. Our compression-sealed glazing blocks music bass and crowd chatter.
Islington & Camden Approved
Clerkenwell straddles two boroughs. Our installations comply with both Islington and Camden conservation policies. Internal, reversible, no planning permission.
Local Noise Profile
Every street has a different noise character. Here are the key problem zones we've identified and treated:
Farringdon Road / A201
Major north-south arterial with heavy bus and commercial traffic at 72–80dB. The road's position in a valley amplifies noise for properties on Clerkenwell Road and surrounding streets.
Affected postcodes: EC1R 3AR, EC1M 3JB, EC1R 0DU
Clerkenwell Road / A5201
East-west traffic corridor connecting Angel to Smithfield. Bus routes 55, 243, and 63 create sustained diesel rumble. The junction with Farringdon Road is a particular noise hotspot.
Affected postcodes: EC1R 5DB, EC1M 5PQ, EC1M 5RS
Exmouth Market / Rosebery Avenue
Evening restaurant noise, outdoor dining, and late-night bar traffic create 65–75dB from 6pm to midnight. Weekend brunch crowds extend noise into Saturday/Sunday mornings.
Affected postcodes: EC1R 4QL, EC1R 4QD, EC1R 0JH
Thameslink / Farringdon Station Corridor
Mainline rail services and Crossrail (Elizabeth Line) create intermittent noise events at 68–76dB. Structural vibration from deep-level tunnelling affects buildings within 100m of the alignment.
Affected postcodes: EC1M 3HN, EC1A 4JA, EC1M 6BN
Glass Performance: Sound Reduction vs. Thickness
For properties near high-noise corridors, we recommend 10.8mm acoustic laminate as the benchmark for blocking low-frequency bus rumble, traffic, and mechanical plant noise.
| Glass Type | Thickness | Sound Reduction | Best For |
|---|---|---|---|
| Standard Laminate | 6.4mm | 35–40dB | Side streets, garden squares |
| Enhanced Laminate | 6.8mm | 38–44dB | Bus routes, secondary roads |
| Stadip Silence | 10.8mm | 48–54dB | A-roads, supercars, aircraft, plant noise |

Conservation Area Solutions
Clerkenwell contains several conservation areas spanning two borough boundaries. Secondary glazing is universally accepted as the approved noise solution for these heritage buildings.
Clerkenwell Green Conservation Area
Georgian and Victorian warehouse conversions
Challenge:
Large industrial windows (often metal-framed) with minimal acoustic performance; open-plan interiors that amplify transmitted noise
Our Solution:
Hinged casement secondary panels with heavy 10.8mm glass to add mass to lightweight industrial glazing
Hat & Feathers Conservation Area
Victorian terraces and workshop conversions
Challenge:
Narrow streets creating noise canyons; mixed residential/commercial use adding variable noise sources
Our Solution:
Full-perimeter treatment with compression seals targeting the broadband urban noise spectrum
New River Conservation Area
Edwardian terraces along the New River Walk
Challenge:
Rosebery Avenue traffic on one side and nightlife noise from Exmouth Market on the other
Our Solution:
Asymmetric specs: 10.8mm on road-facing elevations; 6.8mm on the quieter garden-facing side
Conservation Area & Listed Building Notice
Secondary glazing is the preferred choice for Grade II listed buildings and conservation areas in the London Borough of Islington (with parts in Camden). Because it is installed on the interior, is fully reversible, and makes no alteration to the external façade, it typically requires no planning permission.
Our systems are designed to be invisible from the street and fully compliant with local conservation policies. We handle all compliance documentation as standard.
