How much should I budget for security double-glazed units in Havant?

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
- Made to measure for each sash, light and door panel
- Laminated inner pane, outer pane or both
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Low-E coating and argon fill for insulation
- Security glazing tape or clips where beads are external
- Toughened outer pane where safety glass is required

What to think about first
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.
Consents and safety: 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 Havant: questions
Can you survey in Havant and nearby towns?
Yes. Surveys in Havant, Waterlooville and Portsmouth are booked around 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.
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.
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.
