How much do security double-glazed units cost in Lisburn?
Budget £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Lisburn, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
A security double-glazed unit is a sealed unit in which one or both panes are laminated glass, usually the inner pane, so the window keeps its insulation but resists being broken through. It fits the same frame as a standard unit and is the simplest way to add security to modern windows and doors.
What you can specify
- Security glazing tape or clips where beads are external
- Toughened outer pane where safety glass is required
- Warm-edge spacer bars in black, grey or white
- Laminated inner pane, outer pane or both
- Obscure and decorative glass for bathrooms and doors
- 24 mm, 28 mm and other overall thicknesses to suit frames

Things to decide before you order
Internal or external beads
If your beads are on the outside, we add security tape or clips so the unit cannot be lifted out after the beads are removed.
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
Rules that apply in Northern Ireland
Safety glass in critical locations
In Northern Ireland, safety glazing is covered by Part V of the Building Regulations (Northern Ireland) 2012, with guidance in Technical Booklet V. It follows a critical-location approach similar to Great Britain, covering glazing in and beside doors and at low level. Laminated or toughened safety glass is the usual answer; building control at the council can confirm the detail.
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 double-glazed units in Lisburn: questions
Do you cover Belfast as well as Lisburn?
Yes. As well as Lisburn, we can arrange surveys in nearby Belfast, Newtownabbey and Lurgan. Dates depend on installer availability.
Will a laminated unit be heavier?
A little. A laminated pane weighs about the same as a solid sheet of the same thickness. On large opening sashes we check hinges and friction stays.
Can I just replace the glass and keep my frames?
Yes, if the frames are sound. We measure each unit, make security units to the same size and fit them into your existing frames.
Which pane should be laminated?
Usually the inner pane, so smashing the outer pane does not create an opening. On doors and low panes the outer pane is normally toughened to meet safety rules.
