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.

Before the glass is ordered
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.
Glazing rules in Northern Ireland
Replacing glass in an existing frame
Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.
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.

Security secondary glazing in Coleraine: questions
Can you survey in Coleraine and nearby towns?
Yes. Surveys in Coleraine, Ballymoney and Limavady are booked around 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.
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.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
