What is the price of security secondary glazing in Northamptonshire?
Our guide range for security secondary glazing in Northamptonshire is £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window, including fitting. The survey is free for new installations and your fixed price follows in writing.
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
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Fixed within the reveal, leaving the original window untouched
- Laminated glass in slim aluminium frames
- Suits sash, casement and arched openings
- Low-E glass for better insulation
- Noise and draught reduction

Questions we will ask at the survey
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
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
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.
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 Northamptonshire: questions
Which towns in Northamptonshire do you cover?
We can arrange work anywhere in Northamptonshire, including Northampton, Corby, Kettering, Wellingborough and Rushden, 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.
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.
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.
