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 to think about first

How it opens

Match the opening style to the original window so both can be opened, cleaned and used for ventilation.

Frame colour and sightlines

Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.

Consents and safety: 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 Gerrards Cross: questions

Do you cover Chalfont St Peter as well as Gerrards Cross?

Yes. As well as Gerrards Cross, we can arrange surveys in nearby Chalfont St Peter, Uxbridge and Rickmansworth. 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.

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.

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.
