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.

Things to decide before you order

Listed building consent

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

Frame colour and sightlines

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

Rules that apply in Northern Ireland

Northern Ireland

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.

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 County Down: questions

Which towns in County Down do you cover?

We can arrange work anywhere in County Down, including Banbridge, Bangor, Comber, Downpatrick and Holywood, and in other towns across the area.

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.

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.
