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.

- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Fixed within the reveal, leaving the original window untouched

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: Scotland
Listed buildings and conservation areas
Listed buildings in Scotland need listed building consent from the council for works affecting their character, which can include historic glass, glazing bars and sash windows. Historic Environment Scotland is consulted on some cases and publishes guidance on traditional windows. Conservation areas bring extra scrutiny of shopfronts and external changes.
Planning permission
Under the Scottish planning system the council decides whether a new or altered shopfront needs planning permission; changing the glass in an existing frame usually does not. Bollards or barriers in a road or footway need consent from the roads authority, which is normally the council.

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