Secondary glazing for Hornsey homes
Homes in Hornsey are mostly bay-fronted Victorian and Edwardian terraces, flat conversions and some newer blocks. 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. For offices and shops in noisy locations, secondary glazing improves working comfort without altering the external facade, which helps where landlords or planners restrict changes.
The East Coast Main Line runs past Hornsey station and the big train depot, so homes nearby can be noisy. Acoustic glazing, which uses two different thicknesses of glass, reduces that. Hornsey is about 3.5 miles from our Edmonton factory, and we always check freeholder consent for flats before fitting.
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
- Suitable where replacement is restricted
- Panels open or lift out for cleaning
Questions from Hornsey
Do I need planning permission for secondary glazing in Hornsey?
Some streets in Hornsey fall within conservation areas, so we check with Haringey Council before quoting. Converted flats also need freeholder consent and may need planning permission. 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 Hornsey?
Lead times vary by product and workload — confirmed with your quote. Being about 3.6 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Is secondary glazing allowed in listed buildings in Hornsey?
Secondary glazing is generally seen as less intrusive than replacing original windows, because it sits inside and is reversible. However, listed building consent may still be required, so speak to the council's conservation officer before work starts. We can provide product details to support your application.
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 3.6 miles from Hornsey. We can also bring samples to your home in Hornsey at the free survey.
