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.

Building regulations and safety in Northern Ireland

Northern Ireland

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent from the council for works affecting their character, which can include historic glass and sash windows. The Department for Communities' Historic Environment Division advises on these cases. Conservation areas bring extra scrutiny of shopfronts and external changes.

Planning permission

Planning in Northern Ireland is handled by the eleven councils, which decide whether a new or altered shopfront needs permission; changing the glass in an existing frame usually does not. Bollards or barriers on a public footway need consent from the Department for Infrastructure's roads service.

Security secondary glazing in Carrickfergus: questions

Can you survey in Carrickfergus and nearby towns?

Yes. Surveys in Carrickfergus, Holywood and Newtownabbey are booked around 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.
