What should security double-glazed units cost in Limavady?

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.

Before the glass is ordered
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
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.
Glazing rules in 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.
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.

Security double-glazed units in Limavady: questions
Do you cover Coleraine as well as Limavady?
Yes. As well as Limavady, we can arrange surveys in nearby Coleraine, Derry and Ballymoney. Dates depend on installer availability.
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.
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.
