What should security double-glazed units cost in Bishop's Stortford?
Guide prices for security double-glazed units in Bishop's Stortford are £174 to £594 including VAT (£145 to £495 plus VAT) per unit for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.
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 goes into security double-glazed units
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Made to measure for each sash, light and door panel
- Toughened outer pane where safety glass is required
- Security glazing tape or clips where beads are external
- Warm-edge spacer bars in black, grey or white
- Low-E coating and argon fill for insulation

Before the glass is ordered
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.
Glazing rules 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.
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Security double-glazed units in Bishop's Stortford: questions
Can you survey in Bishop's Stortford and nearby towns?
Yes. Surveys in Bishop's Stortford, Harlow and Hoddesdon are booked around installer availability.
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.
