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.

Things to decide before you order
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
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
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.
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 Willesden: questions
Do you cover Cricklewood as well as Willesden?
Yes. As well as Willesden, we can arrange surveys in nearby Cricklewood, Notting Hill and Shepherds Bush. 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.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
Is secondary glazing safe for escape windows?
It can be, as long as it opens quickly from inside without a key. We design catches and handles for that.
