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
- Noise and draught reduction
- Locks and catches that open from inside without a key
- Fixed within the reveal, leaving the original window untouched

Things to decide before you order
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Rules that apply 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.
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 Preston: questions
Can you survey in Preston and nearby towns?
Yes. Surveys in Preston, Leyland and Chorley 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.
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.
