Security secondary glazing in Holywood: what will it cost?
Guide prices for security secondary glazing in Holywood are £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.
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
- Low-E glass for better insulation
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Colour-matched frames to suit the room
- Fixed within the reveal, leaving the original window untouched

Getting the right glass for your building
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
What the rules say in Northern Ireland
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.
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.

Security secondary glazing in Holywood: questions
Do you cover Newtownabbey as well as Holywood?
Yes. As well as Holywood, we can arrange surveys in nearby Newtownabbey, Belfast and Carrickfergus. Dates depend on 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.
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.
