How much should I budget for security secondary glazing in Magherafelt?
Our guide range for security secondary glazing in Magherafelt is £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window, including fitting. The survey is free for new installations and your fixed price follows in writing.
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.
Choices you can make
- Locks and catches that open from inside without a key
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Suits sash, casement and arched openings
- Laminated glass in slim aluminium frames
- Noise and draught reduction
- Colour-matched frames to suit the room

What to think about first
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.
Consents and safety: 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 Magherafelt: questions
Which areas near Magherafelt do you cover?
We can arrange work in Magherafelt and in nearby Cookstown (10 miles), Ballymena (15 miles) and Antrim (16 miles). Dates depend on installer availability.
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.
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.
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.
