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.

Questions we will ask at the survey

Overall thickness

The new unit must suit the frame's glazing rebate. If your frames only take thin units, we use thinner laminates or adjust the beads.

Which pane is laminated

Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.

Security rules for new homes

If you are building a new home in Northern Ireland, ask the council's building control service which security requirements apply. In existing homes nothing obliges you to upgrade glass, but laminated glass to BS EN 356 P1A in doors and in windows beside them is a common benchmark taken from guidance in Great Britain.

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 double-glazed units in Belfast: questions

Do you cover Newtownabbey as well as Belfast?

Yes. As well as Belfast, we can arrange surveys in nearby Newtownabbey, Holywood and Lisburn. Dates depend on installer availability.

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.

Do security units reduce noise?

Laminated glass already damps sound better than plain glass, and acoustic interlayers improve it further, which helps on busy roads.

How long do new units take?

Units are made to order after the survey. Lead times vary with glass type and size, and we confirm them when we quote.
