Security secondary glazing in County Antrim

What should security secondary glazing cost in County Antrim?

Budget £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in County Antrim, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.

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.

Escape and ventilation

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

Windows needed for escape

Fire safety in new building work in Northern Ireland is covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E. Where a room relies on a window for escape, locks, secondary glazing and film must leave it able to open. Laminated glass is not designed to be broken out.

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 Antrim: questions

Which towns in County Antrim do you cover?

We can arrange work anywhere in County Antrim, including Antrim, Ballymena, Ballymoney, Belfast and Carrickfergus, 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.

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.
