What should security double-glazed units cost in Holywood?

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.
Choices you can make
- Low-E coating and argon fill for insulation
- Warm-edge spacer bars in black, grey or white
- Made to measure for each sash, light and door panel
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Security glazing tape or clips where beads are external
- Toughened outer pane where safety glass is required

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.
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.
Glazing rules in Northern Ireland
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.
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 Holywood: questions
Which areas near Holywood do you cover?
We can arrange work in Holywood and in nearby Newtownabbey (3 miles), Belfast (5 miles) and Carrickfergus (6 miles). Dates depend on installer availability.
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.
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.
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.
