N1 · N5 · N7 Heritage Specialists
Islington's Georgian and early Victorian terraces are among London's finest — and its bar-and-restaurant strip on Upper Street is among the loudest. Between late-night bus routes on the A1, East Coast Main Line rail through Canonbury and Highbury, and constant City Road traffic, most N1 residents live with a chronic noise problem.
Our secondary glazing installers deliver up to 54dB reduction using 10.8mm Stadip Silence acoustic laminate, fully reversible and routinely approved by Islington conservation officers across Barnsbury, Canonbury, Highbury and De Beauvoir.
Upper Street, Essex Road and the A1 through Angel measure 76–82dB at facade level with sustained bus, bar and taxi traffic well past 2am. Canonbury and Highbury terraces also face East Coast Main Line rail noise — sustained rumble plus periodic wheel-squeal peaks around 78–84dB.
Islington's conservation area coverage is one of the densest in London — replacement double glazing is rarely permitted. Internal secondary glazing is the route that satisfies both the borough's heritage regime and the actual acoustic problem.

Islington Reviews
"Upper Street bar noise past 2am was the problem. Islington conservation approved the internal install without issue and the outcome is genuinely transformative — 80dB street noise reads as 30dB indoors."

Grade II Georgian terrace
"The East Coast Main Line runs alongside our building — the wheel-squeal peaks were the worst. The 10.8mm laminate handles both the sustained rumble and the peaks. Bedrooms are transformed."

ECML-adjacent flat
"North London Line plus the A1 was our double-hit. In-house team, tidy install over two days, ten-year guarantee. Best decision we've made on the flat."
