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
- Laminated glass in slim aluminium frames
- Noise and draught reduction
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Low-E glass for better insulation
- Colour-matched frames to suit the room
- Fixed within the reveal, leaving the original window untouched

Questions we will ask at the survey
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Building regulations and safety in 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.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Security secondary glazing in Hampshire: questions
Which towns in Hampshire do you cover?
We can arrange work anywhere in Hampshire, including Southampton, Portsmouth, Basingstoke, Gosport and Waterlooville, and in other towns across the area.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
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.
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.
