Secondary glazing for EN7 homes
In modern homes with sound double glazing, secondary glazing is mainly worthwhile for noise, particularly in bedrooms facing main roads, railways or flight paths.
In 1930s bays, secondary glazing can follow each facet of the bay or span across it, so we measure carefully around radiators, sills and curtain tracks. Older cottages with small leaded or timber windows can keep their character with discreet secondary panels, hinged or removable so the originals stay accessible for maintenance.
Many homes here have had their windows replaced at least once, and the oldest units are starting to fail. Bungalows and detached houses often have large picture windows and patio doors. EN7 is about 7.3 miles from our Edmonton factory, via the A10. Cuffley, nearby, falls under EN6.
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
- Panels open or lift out for cleaning
Questions from EN7
Do I need planning permission for secondary glazing in EN7?
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 EN7?
Lead times vary by product and workload — confirmed with your quote. Being about 7.3 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 7.3 miles from EN7. We can also bring samples to your home in EN7 at the free survey.
