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.
Options for security double-glazed units in Islington
- Low-E coating and argon fill for insulation
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Warm-edge spacer bars in black, grey or white
- Security glazing tape or clips where beads are external
- Obscure and decorative glass for bathrooms and doors
- Laminated inner pane, outer pane or both

Things to decide before you order
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.
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 England
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Security double-glazed units in Islington: questions
Which areas near Islington do you cover?
We can arrange work in Islington and in nearby Highbury (1 mile), Holloway (1 mile) and Camden Town (2 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.
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.
