What should security double-glazed units cost in Crawley?
Our guide range for security double-glazed units in Crawley is £174 to £594 including VAT (£145 to £495 plus VAT) per unit, including fitting. The survey is free for new installations and your fixed price follows in writing.
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
- Low-E coating and argon fill for insulation
- Laminated inner pane, outer pane or both
- Warm-edge spacer bars in black, grey or white
- Made to measure for each sash, light and door panel
- Toughened outer pane where safety glass is required
Fitting in Crawley and nearby
We arrange surveys and fitting across Crawley and the RH11 postcode district, and in nearby Horley (4 miles), Horsham (7 miles) and East Grinstead.
West Sussex includes Chichester's Georgian city centre, the seaside towns of Worthing and Bognor Regis, Crawley's new-town centre and business parks, and Horsham's market-town streets.
Good candidates for security double-glazed units:
- Ground-floor and basement windows
- Windows in flats on walkways and balconies
- Glazed back and side doors
- Replacing misted or damaged units
Before the glass is ordered
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.
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
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.
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 Crawley: questions
Do you cover Horley as well as Crawley?
Yes. As well as Crawley, we can arrange surveys in nearby Horley, Horsham and East Grinstead. Dates depend on installer availability.
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.
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.
