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.
What you can specify

- Colour-matched frames to suit the room
- Laminated glass in slim aluminium frames
- Vertical sliding, horizontal sliding, hinged and lift-out styles

What to think about first
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Consents and safety: 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.
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.

Security secondary glazing in Larne: questions
Do you cover Carrickfergus as well as Larne?
Yes. As well as Larne, we can arrange surveys in nearby Carrickfergus, Newtownabbey and Bangor. Dates depend on installer availability.
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.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
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.
