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.
What you can specify
- Security glazing tape or clips where beads are external
- Made to measure for each sash, light and door panel
- Warm-edge spacer bars in black, grey or white
- Low-E coating and argon fill for insulation
- Laminated inner pane, outer pane or both
- Toughened outer pane where safety glass is required

Getting the right glass for your building
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.
What the rules say 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.
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.

Security double-glazed units in Cambridgeshire: questions
Which towns in Cambridgeshire do you cover?
We can arrange work anywhere in Cambridgeshire, including Peterborough, Cambridge, Wisbech, St Neots and Huntingdon, and in other towns across the area.
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.
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.
