Honest figures on how much quieter acoustic triple glazing gets. Acoustic triple glazing combines a three-pane unit with at least one laminated acoustic pane and panes of different thickness, which together reduce traffic and aircraft noise more than a standard unit.

Rules for acoustic triple glazing in England

The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.

Planning: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.

How it works

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions from Bishop's Stortford

Do trickle vents let noise in?

Standard vents can. Acoustic trickle vents are designed to keep ventilation while reducing sound.

Does triple glazing reduce noise more than double?

A little: the third pane adds about 3 dB, sometimes less. Laminated acoustic glass makes the bigger difference, whether in a double or triple unit.

Do I need permission for acoustic triple glazing in Bishop's Stortford?

In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
