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.

Questions we will ask at the survey

Escape and ventilation

On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.

Listed building consent

Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.

Building regulations and safety in England

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.

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.

Security secondary glazing in Streatham: questions

Do you cover Mitcham as well as Streatham?

Yes. As well as Streatham, we can arrange surveys in nearby Mitcham, Brixton and Wimbledon. Dates depend on installer availability.

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.

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.

Can I still open my sash windows?

Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
