SE10 UNESCO Heritage Acoustic Specialists
Greenwich Secondary Glazing & Soundproof Sash Windows
Maritime Greenwich is a UNESCO World Heritage Site — Wren's Old Royal Naval College, the Queen's House, Royal Observatory and the Georgian and Victorian streets that surround them. Property values of £700k–£3M+ reflect the heritage significance. But the A102 Blackwall Tunnel approach, DLR services through Cutty Sark and Greenwich stations, and year-round tourist coach traffic create acoustic challenges that single-glazed heritage windows cannot address. Our secondary glazing delivers up to 54dB reduction while satisfying both Greenwich conservation policy and UNESCO heritage integrity.
UNESCO Compliant
The only window improvement that preserves the Maritime Greenwich World Heritage Site's integrity. Internal, fully reversible, invisible from the street — accepted by Royal Borough of Greenwich and Historic England.
A102 & Tourist Traffic
A102 Blackwall Tunnel approach carries 80,000+ vehicles daily at 78–82dB. Coach tourism on Romney Road and King William Walk adds sustained low-frequency engine noise — both blocked by 10.8mm Stadip Silence.
DLR & Southeastern Rail
DLR services through Cutty Sark every 4–6 minutes plus Southeastern through Greenwich station generate 70–76dB events. Acoustic laminate plus extended cavity blocks both surface and underground rail signatures.
Riverside Thermal Fix
Riverside exposure plus Georgian and Victorian single glazing creates significant heat loss. 65% U-value reduction and 30–40% heating-bill savings on large heritage properties — without external alteration.
Local Noise Profile
Every street has a different noise character. Here are the key problem zones we've identified and treated:
A102 Blackwall Tunnel Approach
80,000+ vehicles daily including major HGV traffic to and from the Blackwall Tunnel generating sustained 78–82dB. Properties along the Greenwich Peninsula and East Greenwich corridor face the highest sustained acoustic exposure in SE10.
Affected postcodes: SE10 0AA, SE10 0PH, SE10 0SB
Romney Road & King William Walk
Tourist coach traffic, river-bus shuttles, and bus routes 129, 177, 180, 188, 199, 286, 386 converge around the Old Royal Naval College and Cutty Sark generating sustained 70–76dB plus weekend tourist crowd noise reaching 65–72dB.
Affected postcodes: SE10 9LW, SE10 9NF, SE10 9HT
Greenwich High Road (A206)
Through-traffic between New Cross and Woolwich at 72–78dB. Bus-heavy corridor with sustained low-frequency rumble affecting Victorian terraces along Royal Hill, Crooms Hill foot, and Greenwich South Street.
Affected postcodes: SE10 8JA, SE10 8NN, SE10 8LX
DLR Cutty Sark to Greenwich
DLR services every 4–6 minutes generate 70–76dB events at street level. Properties along Greenwich Church Street, Stockwell Street and the DLR cutting between stations experience continuous train movement noise from 05:30 to 00:30.
Affected postcodes: SE10 9BJ, SE10 9JN, SE10 8LL
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
Maritime Greenwich's UNESCO World Heritage status and the Royal Borough of Greenwich's conservation policies make external window replacement effectively impossible. Secondary glazing is the only window improvement that satisfies UNESCO, Historic England, and the Royal Borough — it is fully internal, reversible, and invisible from the street, requiring no planning permission.
Maritime Greenwich World Heritage Site
Old Royal Naval College, Queen's House, Royal Observatory, and surrounding Georgian and Victorian residential fabric
Challenge:
UNESCO requires preservation of the World Heritage Site setting; Greenwich conservation officers prohibit any external window alteration; A102 and tourist traffic exposure
Our Solution:
10.8mm Stadip Silence in ultra-slim 25mm frames, custom RAL matched to original paint colours; vertical sliding operation mirroring Georgian sash geometry; UNESCO-compliant internal-only installation
West Greenwich Conservation Area
Georgian and early Victorian terraces around Crooms Hill, Royal Hill and Gloucester Circus
Challenge:
Greenwich conservation officers protect the Georgian streetscape; sustained Greenwich High Road bus and through-traffic noise
Our Solution:
Slim-profile frames matched to Georgian glazing bar geometry; concealed magnetic perimeter seals; phased installation across 12–18 windows
East Greenwich Conservation Area
Victorian terraces along Trafalgar Road and the streets behind the A102
Challenge:
Direct A102 Blackwall Tunnel approach exposure; Victorian bay windows demand bespoke per-opening solutions
Our Solution:
Custom-surveyed angled bay frames following original geometry; maximum-cavity installation in deep Victorian reveals; 10.8mm acoustic laminate throughout
Conservation Area & Listed Building Notice
Secondary glazing is the preferred choice for Grade II listed buildings and conservation areas in the Royal Borough of Greenwich. 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.
