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.
What goes into security secondary glazing
- Laminated glass in slim aluminium frames
- Locks and catches that open from inside without a key
- Colour-matched frames to suit the room
- Low-E glass for better insulation
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Fixed within the reveal, leaving the original window untouched

Northamptonshire mixes Northampton's town-centre retail and Victorian shoe-trade streets with newer estates around Corby and Wellingborough and stone villages towards Oundle.
Good candidates for security secondary glazing:
- Homes on busy roads wanting noise reduction
- Offices in historic buildings
- Period sash windows with original glass
- Listed homes and buildings in conservation areas
Before the glass is ordered
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Glazing rules 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 Northampton: questions
Can you survey in Northampton and nearby towns?
Yes. Surveys in Northampton, Wellingborough and Daventry 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.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
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.
