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.
Choices you can make
- Locks and catches that open from inside without a key
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Suits sash, casement and arched openings
- Colour-matched frames to suit the room
- Laminated glass in slim aluminium frames
- Fixed within the reveal, leaving the original window untouched

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.
Building regulations and safety 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.
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 Barnes: questions
Which areas near Barnes do you cover?
We can arrange work in Barnes and in nearby Chiswick (1 mile), Putney (2 miles) and Fulham (2 miles). 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.
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.
