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.
Glass and fitting options
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Colour-matched frames to suit the room
- Fixed within the reveal, leaving the original window untouched
- Locks and catches that open from inside without a key
- Laminated glass in slim aluminium frames
- Noise and draught reduction

What to think about first
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
Consents and safety: England
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.
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.

Security secondary glazing in Havant: questions
Can you survey in Havant and nearby towns?
Yes. Surveys in Havant, Waterlooville and Portsmouth are booked around installer availability.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
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.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
