Security secondary glazing is a separate slim window fitted on the room side of an existing window, glazed with laminated glass so it forms a second barrier. It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.

- Fixed within the reveal, leaving the original window untouched
- Low-E glass for better insulation
- Noise and draught reduction

Things to decide before you order
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Rules that apply in England
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.
Windows needed for escape
Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

Security secondary glazing in Holloway: questions
Which areas near Holloway do you cover?
We can arrange work in Holloway and in nearby Highbury (1 mile), Archway (1 mile) and Camden Town (1 mile). Dates depend on installer availability.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
Do I need permission for secondary glazing in a listed building?
It depends on the building and the council. Internal secondary glazing usually has less impact than replacement windows, but listed building consent may still be needed. Ask the conservation officer before ordering.
Will secondary glazing cause condensation?
A well-fitted unit usually reduces condensation on the inner pane. Some ventilation of the gap may be needed, which we discuss at the survey.
