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.

24 mm, 28 mm and other overall thicknesses to suit frames
Laminated inner pane, outer pane or both
Made to measure for each sash, light and door panel

Questions we will ask at the survey

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.

Energy performance

Choosing low-E glass, argon and warm-edge spacers keeps the window as efficient as possible, often better than the unit being replaced.

Building regulations and safety in Northern Ireland

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.

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.

Security double-glazed units in Coleraine: questions

Which areas near Coleraine do you cover?

We can arrange work in Coleraine and in nearby Ballymoney (7 miles), Limavady (13 miles) and Ballymena (24 miles). 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.
