Security secondary glazing in Purley: what will it cost?

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.

Getting the right glass for your building

Frame colour and sightlines

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

Listed building consent

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

What the rules say in England

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.

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.

Security secondary glazing in Purley: questions

Which areas near Purley do you cover?

We can arrange work in Purley and in nearby Coulsdon (2 miles), South Croydon (2 miles) and Wallington (3 miles). 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.

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.
