Secondary glazing for Barnsbury homes

Around Barnsbury you will mostly find Georgian terraces, early Victorian squares and converted period flats. On listed buildings, secondary glazing is often the preferred way to improve comfort, but check with the conservation officer as listed building consent may still be needed.

Behind Victorian sash windows, vertical sliding secondary glazing aligned with the meeting rail keeps the view uninterrupted and lets both windows open for ventilation. For flats where the lease or freeholder prevents changing external windows, secondary glazing fitted inside is usually the simplest way to reduce traffic noise and heat loss.

A lot of these houses are now split into flats, so the freeholder may need to sign off before work starts. We also plan deliveries carefully, as parking near Upper Street and the Caledonian Road is tight and often permit-only.

Secondary glazing is a discreet second window fitted on the inside of your existing windows, leaving the originals untouched. It suits listed buildings, conservation areas, flats where external windows cannot be changed, and anyone wanting to cut noise and draughts without replacing period windows.

  • Keeps original windows in place
  • Reduces draughts and outside noise
  • Suitable where replacement is restricted

Questions from Barnsbury

Do I need planning permission for secondary glazing in Barnsbury?

Much of Barnsbury sits within Islington Council's Barnsbury Conservation Area, so we check the council's design guidance on sash windows and front doors before quoting. Secondary glazing is fitted internally, so it does not usually need planning permission or Building Regulations approval, but listed buildings may need listed building consent first.

How soon can you fit secondary glazing in Barnsbury?

Lead times vary by product and workload — confirmed with your quote. Being about 5.6 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.

Can I still open my windows with secondary glazing fitted?

Yes. Secondary glazing can be made as sliding, hinged or lift-out panels, so you can open both the secondary unit and the original window for ventilation and cleaning. Fixed panels are also possible for windows you never need to open.

Can I see samples before I decide?

Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 5.6 miles from Barnsbury. We can also bring samples to your home in Barnsbury at the free survey.
