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.
Glass and fitting options
- Warm-edge spacer bars in black, grey or white
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Laminated inner pane, outer pane or both
- Made to measure for each sash, light and door panel
- Low-E coating and argon fill for insulation
- Obscure and decorative glass for bathrooms and doors
Covering Bristol
We can arrange surveys and fitting anywhere in Bristol, including Clifton and Bedminster. Dates depend on installer availability.
Bristol's glazing ranges from Georgian sash windows in Clifton and Kingsdown to Victorian bay fronts in Bedminster and modern glazed offices around Temple Quarter and the harbourside.
Typical places for security double-glazed units:
- Windows in flats on walkways and balconies
- Patio doors and bifolds
- Replacing misted or damaged units
- Glazed back and side doors
Things to decide before you order
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.
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.
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 Bristol: questions
Which parts in Bristol do you cover?
We can arrange work anywhere in Bristol, including Clifton, Bedminster, Easton, Fishponds and Southville.
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.
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.
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.
